HeatLink Plumbing PEX Tubing

 

You can plumb your entire house with Heat-Link Plumbing PEX. The HeatLink Potable Water System features PureLink PEX-a tubing, the EasyFit manifold system. The unique HeatLink PEX-a process is based on a method developed during the 1970’s and uses organic peroxide to chemically cross-link the polyethylene during the manufacturing process. The PEX-a process produces a higher degree and greater uniformity in crosslinking, resulting product with significantly improved material properties with respect to temperature, pressure, strength and chemical resistance. Press sleeve technology has been used for decades worldwide in plumbing systems, and has also been used extensively for pneumatic and hydraulic applications.

HeatLink’s superior potable water system carries all necessary approvals for North American installations, and offers significant advantages and benefits in comparison to both copper and most common PEX plumbing systems in use today.

 

HeatLink EasyFit Plumbing PEX Manifolds

 

Heatlink EasyFit Plumbing PEX Manifolds - Example

Heatlink Easyfit Pex Manifolds come in 2 and 3 Port Tees and are sold with 1/2" PEX adapters. So just order the actual amount of ports you need and you should be good to go. There are several different End Connection you need to choose from as well as 3/4" Tee to allow you to send hot or cold water to a separte plumbing manifold in a different location. If you want to use this manifold with 3/8 Inch PEX tubing - buy our Coupler 1/2 by 3/8 inch for each branch you want to use with 3/8 Inch PEX.


Use silicone lubricant to lubricate dry o-rings to ensure a tight seal.
In case a leak develops during testing, remove pressure from system, clean the o-ring, and reapply silicon lube.
When placing the manifold into the supporting bracket, place the bottom snap-in lock in the bottom (braced) notch in bracket and then rotate it so that the top snaps into place.
In order to prevent stress on the manifold supply end connections, the supply piping must be braced or supported, parallel to the manifold and centred with the manifold’s inlets.  Please visit us at  Houseneeds.com to purchase products.

When you save energy, you're saving money and the environment!

An energy-efficient home will keep your family comfortable while saving you money. Whether you take simple steps or make larger investments to make your home more efficient, you'll see lower energy bills. Over time, those savings will typically pay for the cost of improvements and put money back in your pocket. Your home may also be more attractive to buyers when you sell.

The 113 million residences in America today collectively use an estimated 22% of the country's energy. Unfortunately, a lot of energy is wasted through leaky windows or ducts, old appliances, or inefficient heating and cooling systems. When we waste energy in our homes, we are throwing away money that could be used for other things. The typical U.S. family spends at least $2,000 a year on home utility bills.

You can save 10% - 50% each year by making smart energy choices.

Solar Heating Tax Credit up until December 31, 2016 Solar Water Heating Federal Tax Credit Solar Heating can save you up to 30% on your taxes in addition to year-round savings on your energy bill.

On February 17, 2009, President Obama signed a stimulus bill (The American Recovery and Reinvestment Act of 2009) that made some significant changes to the energy efficiency tax credits. At least half of the energy generated by the “qualifying property” must come from the sun. Homeowners may only claim spending on the solar water heating system property, not the entire water heating system of the household. Solar Heating Tax Credits are not limited to the $1,500.00 Tax Credit Cap. The credit is not available for expenses for swimming pools or hot tubs. The water must be used in the dwelling. The system must be certified by the Solar Rating and Certification Corporation (SRCC). Improvements made up until December 31, 2016 can be claimed on your taxes (filed by April 15, 2017) — use IRS Tax Form 5695 (2009 version). For more information on the bill, check out the U.S. Department of Energy website. What is a tax credit? A Solar Water Heating Tax Credit is not received when you buy the product, like an instant rebate. A Tax Credit on Solar Water Heating System is claimed on your federal income tax form at the end of the year. The credit then increases the tax refund you receive or decreases the amount paid in. Tax credits vs. tax deductions. In general, a tax credit is more valuable than a similar tax deduction. A tax credit reduces the tax you pay, dollar-for-dollar. Tax deductions – such as those for home mortgages and charitable giving, for example – lower your taxable income. If you are in the 30 percent tax bracket, your income tax is reduced by 30 percent of the value of a tax deduction. But a tax credit reduces your federal income tax by 100 percent of the amount of the credit. For more information on Federal Tax Credits for Energy Efficiency, click here.

Perfect Summer Project

Only you can control the sources of pollutants in your home, but Fantech HEPA Filtration can help provide ventilation and filtration. Tighter houses prevent outside air from getting in, but they also prevent indoor air pollutants and allergens from carpet, pets, mold, plants, cooking and tobacco smoke from getting out. Your family could be breathing air that is five times more polluted than the air outside.

 Fantech’s Whole House HEPA installs on your home’s forced air furnace/air handler or can be used as an independent system mounted in the attic, crawl space or closet. The unit is small, compact and very affordable. A powerful 240 CFM fan directs air through a series of three filters then delivers clean, safe, healthy air back into your entire home. Don't let invisible indoor air pollutants affect your home and the health of your family.

Why Choose A Whole House HEPA Over A Portable Filtration Unit? Portable HEPA units are designed to clean only the air in a single room or small area of the home. The Fantech Whole House HEPA will clean the total volume of air in an average house once each hour. Ideal for homes up to 3600 sq. ft.

Did You Know...

HousePex's molecular orientation is achieved during extrusion, which is a very unique process. Peroxide cross-linking occurs simultaneously with the orientation and guarantees optimal tubing properties (pex stands for polyethylene cross-linked).

EVOH - Refers to a type of oxygen barrier that is commonly used in Pex Tubing. EVOH stands for ethylene vinyl alcohol, this compound prevents oxygen diffusion and is bonded to the Pex during the manufacturing process.

HousePex is Manufactured in Sweden on state-of-the-art
extruding machines, uses Peroxide Extrusion which is the most
flexible / strongest and meets SDR-9 specification (standard dimensional ratio).

Whole House Fan Basics

On a sunny day the temperature of an attic can reach as high as 140 degrees! And this high temperature in your attic will keep the indoor temperature higher than the outdoor temperature for several (or more) hours after the sun goes down.

By pulling heat out of your home with the a Whole House Fan, cooler outside air is drawn into the home. The heated air is then pushed out of your home through the attic vents. WHF's can make you more comfortable and could reduce your air conditioning bills.

When you choose a fan, divide that fans cfm by 750 (1 square foot of opening for each 750 cfm (cubic feet per minute) of airflow). This number determines the amount of square footage of net free air required to properly vent. To allow for any restrictions created by screening and louvers multiply that number by 2. This number is the minimum square footage of venting required for the fan to exhaust properly. One can choose a combination of ridge, soffit and/or gable venting to make up the square footage.

The benefits of a PEX Radiant Heat System:

Comfort - It may be freezing outside, but your pex radiant heat system will keep you warm from head to toe. Nothing compares to the comfort and surrounding warmth of a pex underfloor radiant heat system in your home using our PEX Tubing. We have PEX-A, PEX-C and Alum PEX Tubing.


Efficiency - Radiant Heat with PEX is the most efficient heating system available. Radiant underfloor heat costs less to heat your home than any other type of heating system by being able to lower the thermostat temperture while still staying toasty warm. Generally, you can save 15 to 20% as compared to forced-air or hydronic baseboard heating systems.


Zoning - With pex radiant heat, you can zone different areas of your home to different temperatures to fit your lifestyle, unlike central heating and air.


Flexibility - A radiant floor heating system can be installed under practically any type of flooring, such as carpeting, tile, linoleum, wood floors, etc. Easily add underfloor heat to small areas such as bathrooms or kitchens.


Improves Air Quality - PEX Radiant Heat reduces dust mites and air borne allergens by 60%-90%. No other heating system reduces allergies as effectively as radiant heat.


Interior Decorating Freedom - PEX Radiant heat systems are installed with PEX Tubing and is within the structure of your home, which means you will not have to consider vents, hydronic baseboards, hydronic radiators, or drafty areas when decorating and furnishing your home.


Adds Value to Your Home - There are many other potential implementations of pex radiant heat in your home such as heating your garage or melting snow from your driveway in winter. A radiant heating system will increase the value of your home more than it costs to install.

Surge Suppressor and Power Conditioning Systems

On residential units we emphasize the PowerGUARD’s ability to protect the whole house. In fact, the PowerGUARD is ETL listed for spike and surge suppression. A common misconception is that the PG is capacitor driven. It is a magnetic choke based system that improves Power Factor inductively. Along with the energy savings, the power quality is improved (better balanced voltage, reduced amperage and spike / surge protection)which is far more than a capacitor can offer.

With all the heat pump and HVAC applications in the southern part of the country, there is ample opportunity for energy savings for the average homeowner. Some solar installers include a PowerGUARD unit in each application as it protects the Photo Voltaic system from spikes, surges and helps the system last longer as well as reducing total usage for the homeowner.

Did You Know

The earth has a much more constant temperature than the air. It might be 100 degrees in summer and -40 degrees in winter where you live. But a few feet down, the earth will always be a steady temperature.

For every 100 feet you go down into the earth, the temperature rises 1.5 degrees. So if you were to dig down to a depth of 600 feet, assuming the temperature a few feet below ground is 60 degrees, the deeper rock would have a temperature of
69 degrees.

Home Energy Conservation and Tips

Saving energy means more dollars in your pocket, but it is also a powerful way to save our valuable resources. Energy conservation is the most important green initiative that we should take to heart and practice.

We can start with small steps to lighten the "footprints" we leave behind for future generations like the simple changing of a light bulb which can make a dramatic difference in energy efficiency and cost savings (standard incandescent light bulbs with compact fluorescent light bulbs (CFLs) can save 75% of lighting cost).

A surprisingly large number of electrical products—TVs to microwave ovens to air conditioners—cannot be switched off completely without being unplugged. These products draw power 24 hours a day, often without the knowledge of the consumer. We call this power consumption "standby power."

An individual product draws relatively little standby power but a typical American home has forty products constantly drawing power. Together these amount to almost 10% of residential electricity use.

Identify and reduce these energy drains by using smart strips or unplugging when not in use.


Energy Saving Tips

Turn off the lights when you leave a room.

Replace energy-hungry incandescent lights with fluorescent lighting.

Check with your utility company for energy conservation tips.

Use a programmable thermostat that automatically turns off

the air conditioner or heater when you don't need them.

Add insulation to your home.

Use a fan instead of air conditioning.

Use an EPA-approved wood burning stove or fireplace insert

Insulate your water heater or buy a tankless unit.

Install low-flow showerheads.

Solar Collectors

EVACUATED TUBE COLLECTORS:
Another type of active solar collector consists of several
glass tubes, each of which has concentric inner and outer
walls. The annular space between these glass tubes has
been evacuated of air and thus acts like a Thermos®
bottle. Convective heat transfer between the inner and
outer glass tubes is essentially eliminated. A coated
copper absorber strip with attached tubing is located
within the inner glass tube, as shown in figure 12.
Most current-generation evacuated tubes have a
specialized fluid sealed within the internal copper tubing.
When heated, this fluid changes from liquid to vapor
and rises toward the top of the tube. It then passes into
a small copper capsule that fits tightly into a manifold
assembly at the top of the collector. Heat conducts
though this copper capsule into fluid circulating along
the manifold. The fluid sealed within the evacuated
tubes never contacts the fluid in the manifold. As heat
is released from the fluid within the evacuated tube, it
condenses back to a liquid and flows back to the bottom
of the tube ready to repeat the cycle.


FLAT PLATE COLLECTORS:
The principal component in this type of collector is the
absorber plate, which is usually an assembly of copper
sheet and copper tubing. The top surface of the absorber
plate is coated with dark colored paint or electroplated
“selective surface” coating that absorbs the vast majority
of solar radiation striking it. The instant solar radiation
strikes this surface it is converted to thermal energy
(e.g., heat). The copper sheet acts as a wick to conduct
this heat toward the copper tubing that is welded or
otherwise bonded to the sheet. Heat moves across the
copper sheet toward the tubes because the fluid flowing
through the tubes is cooler than the absorber sheet. This
fluid absorbs the heat and carries it out of the collector.
To minimize heat loss, the absorber plate is usually
housed in an enclosure made of aluminum and capable of
withstanding many years of exterior exposure. The sides
and back of this enclosure are insulated with materials
capable of withstanding temperatures in excess of 350ºF,
which might occur if the collector is exposed to intense
sunlight without fluid flow through its absorber plate.
The upper surface of the enclosure is usually tempered
glass with a low iron oxide content. Tempered glass can
withstand high thermal stress as well as potential impact
from hailstones or other objects. Low iron oxide content
glass minimizes absorption of solar radiation as it passes
through on its way to the absorber plate.

Sizing An Electric Tankless Water Heater

When sizing an electric tankless water heater for your home remember to look at the manufactures recommended electric service to the house (in Amperage) for each model you are considering. A common mistake when ordering online is to look at the 220/240 Volts and not the Amperage, often resulting in getting the wrong size and the wasted time of a return.

Our electric tankless water heaters are 97% efficient and are not subject to stand-by losses of conventional tank type water heaters.
This offers a 20% or more savings on the hot water portion of your bill.

Energy Tips

1. If you spend $2000 a year on fuel consider replacing an older boiler (65% efficiency) with a 95% high efficiency boiler. This could save you up to $580 dollars a year!

2. The heating equipment in your home needs regular tune-ups just like your car. Having a professional clean and calibrate your boiler every year can typically save you 5-8% on your bill.

3. Radiant heat is not only more comfortable to your body but you can see savings of 10%-30% in most residences and up to 60% in shops, garages, and warehouses.

4. Check the furnace filter each month, and clean or replace it as needed. Dirty filters block airflow through your heating equipment, increasing your energy bill and shortening the equipment’s life.

5. Fans can suck all the heat out of the average house in little more than an hour. Minimize use of ventilation fans such as bathroom and kitchen hood fans during cold temps.

A Circulator Is Like a Ferris Wheel

Once the system completely filled with water, all the circulator has to do is move it around. It helps to think of a heating system as a Ferris wheel. When a Ferris wheel turns, the weight going up balances the weight coming down. There’s no lifting going on here, there’s only turning. That’s because everything is in perfect balance. The Ferris wheel’s motor doesn’t have to do any lifting. All it has to do is overcome the friction in the bearings (and in the air, of course) to set the big wheel in motion.

We use the term "Pump Head" to describe the force the circulator develops to overcome pressure drop. When we work with closed hot water heating systems, "Pump Head" has nothing to do with the height of the building. It has only to do with the circulator’s ability to overcome friction. That’s because the system is completely filled with water. Height, as far as the circulator is concerned, doesn’t exist. The circulator doesn’t know (or care!) if the building is 100 feet high and ten feet wide, or ten feet high and 100 feet wide. All it knows is friction.
Static pressure has nothing to do with the number of fittings and valves or the width of the building’s piping network. Static pressure has only to do with gravity, and the weight of the column of water.
"Pump Head," on the other hand, has a lot to do with the number of fittings or valves and the size of the building’s piping network. But it has nothing to do with gravity or the fill pressure of the system.

The water has to squeeze through this smaller opening to get out of the volute. The effect you get is similar to what happens when you put your thumb over the end of a garden hose. The velocity increases, doesn’t it? Well, that velocity is the force that moves the water around the system’s pressure drop. Remember, there’s no lifting going on here, nor pulling or pushing either. Circulators turn the water, just like a big Ferris wheel.

Electro Boiler with WarmFlow technology

The Electro Boilers are 100% efficient and the price per KW/h determines the cost of operation. Most models have a built-in electronic aquastat and WarmFlo technology.
WarmFlo will automatically modulate (delivers just the heat you need) eliminating unnecessary energy consumption.

Why Thermal Board works so well:
Non-structural Thermalboard™ is designed specifically for subfloor applications. Thermalboard™ is constructed of a dense composite board covered with aluminum that spreads the heat evenly and quickly from the hydronic tubing. It heats rapidly and is easy to control with setback thermostats for maximum energy efficiency. It contains just enough thermal mass to be effective, but not so much that it’s difficult to control. No other product offers this combination of performance, ease of installation and cost-effectiveness. (Up to 40 BTU SF)

ESTIMATING THE REQUIRED NUMBER OF THERMALBOARDS:
The following calculations can be used for estimating the required number of boards. For experienced installers:
calculate the net square footage of each room and multiply sq ft by
the following factors: Straight – 0.133 Utility – 0.028 Combo End and Utility pieces

Example: For a 600 Sq. ft. room, multiplying 600 by 0.133 gives approximately
80 straight boards. Multiplying 600 by 0.028 gives 17 Utility pieces.
Multiplying 600 by 0.028 gives 17 Combo end pieces. It is always recommended
that additional 10% material excess is added to the estimation.

Radiant Heat Install Options

Radiant Floor Heating Installation Options using PEX Tubing


PEX Radiant Concrete Floors (Slab on Grade)
For concrete floors (slab on grade), the Radiant PEX tubing is attached to the reinforcing mesh with cable ties before the slab is poured. This type of PEX Radiant Floor Heat has a large mass.
With this type of radiant underfloor heat the space can only changed by the radiant floor about 1/2 a degree per hour. Typically the water temperature used in pex water line for this type of radiant floor is between 90° and 115° Fahrenheit. It is imperative that the surface temperature of any PEX Radiant floor stays below 85° or it becomes uncomfortable and unsafe.
Radiant Concrete Floors (Slab on Grade)


PEX in thin slab over wood framing
Simpler in new construction but you can install this type of radiant floor as a retrofit, the radiant PEX Pipe is installed over framed floors and covered with concrete or lightweight concrete. We like this type of pex radiant floor heating the best. Very easy to install and it provides a very even heat. Thin slab PEX radiant floors have a much quicker response time. With this type of radiant floor the space it is heating can be changed by the radiant floor as fast as 2 a degree per hour. Thin slab radiant floors have many floor covering options. (tile, stained concrete, wood using sleepers, carpet, etc.). Typically the water temperature used in this type of radiant floor - the pex water lines are between 90° and 125° Fahrenheit.
A quick note: When installing this type of pex radiant floor heat you need to have a tension break between the concrete and the wood substrate to allow the concrete and the wood floor to expand and shrink at there own rates. We recommend using 6 mil. sheet plastic.

PEX Under Floor Systems with Heat Transfer Plates
In a typical remodeling project, the PEX radiant tubing is snapped into radiant heat transfer plates which radiate heat to the floor above. The radiant heat plates tend to make the floor above them have warm and warmer spots. Still very comfortable. The installation of PEX under floors has its draw backs. PEX when heated expands 1.1 inch per. 10 feet with a 100° temperature rise. Typically the temperature for this type of installation is between 120° and 145° Fahrenheit. If not properly installed this PEX radiant floor can be quite noisy or if you get the wrong type of transfer plates for your pex underfloor heating system.


Under floor installation using
Radiant Heat Transfer Plates


PEX Radiant Tubing Under Floor
In a typical remodeling project, the PEX radiant tubing is hung with hangers below the floor about 1 inch. This allows the PEX radiant tubing to slide a little and sag a little as it expands making for a quiet floor. The hot water running through the PEX radiant tubing heats the air which intern heats the floor above. A insulation with a reflective surface mounted facing up leaving a 3 to 4 inch air space to the bottom of the floor is required. The PEX Radiant Heat from this floor system is very even. The air in this space must be stagnant, meaning all penetrations must be calked and the floor joists where they meet the band joist also. Typically the temperature for this type of PEX installation is between 120 deg. and 165 deg. Fahrenheit. We know of many houses using this method, new construction and existing. In Vermont where tubing was hung 16 inches on center and the water temperature is run from 125 degrees to 180 degrees out of the boiler or with a mixing valve. This has kept houses at a comfortable range with efficiency and no noise. In warmer climates you can run with a cooler temperature, but all this depends on your house's heat loss and other factors.

Rinnai Space Heaters

Rinnai Gas Direct-Vent Space Heaters are freestanding energy efficient heaters with the ability to modulate both its burner and blower to provide maximum efficiency and comfort. The Rinnai Heater incorporates an electronically driven 7-stage gas control system to maintain an even and continuous heat output to give you stable room temperature with unparalleled efficiency in both gas and electrical consumption. The Rinnai Direct-Vent Heaters are attractive, quiet, and compact and have a cool-to-the-touch cabinet. Rinnai Heaters extended life stainless steel heat exchanger transfers 84% of consumed gas energy to useful heat.

How many BTU’s?
We can make a rough approximation of the heat loss by using the square foot rule of thumb; about 35 BTU’s per Sq FT here in VT for a home with 2 x 4 construction, aluminum storms, R-13 in the walls and R-25 in the ceiling.

New construction would be between 20 and 25 BTU’s per sq ft.

Radiant Slab on Grade Install Diary

This project was part of a weekend class taught by HouseNeeds and held by a local design build school, Yestermorrow.

HouseNeeds is here with more how to. This time we are looking at a radiant slab for a garage. If you are going to make the effort to pour a slab, why not lay tubing in it for added comfort and value. Homes with radiant heat are generally valued higher and differentiate themselves on the market. At HouseNeeds we make slabs easy. There are Slab Packages ready for your floor and layout patterns in our Heating University.


Thermal Break/Moisture Barrier
This how-to was a garage project. The floor was prepared, as you would normally prepare a floor for any slab. Soil or gravel is compacted and leveled according to plan. Any necessary drainage is put in place to avoid problems with water touching the slab. The next step is to create a thermal break and moisture barrier. The idea is to avoid letting any heat transfer into the ground below or the adjacent footer.

**We began by laying the Low-e slab shield rolls on the floor. Allow extra at the end and sides, so it will come atleast an inch or so above the pour. The Low-e can be trimmed after. If the slab is in a cold climate, foam board can be inserted around the perimeter for extra insulation. The rolls are then taped together with seam tape, to create a continuous membrane. The Low-e is both a thermal break and moisture barrier. Corners are easily formed and then taped well. We are now ready for welded wire or rebar. This is also the time you want to mark your pour height. This can be done on the footer wall.

Rebar and Welded Wire Mesh
Now it is time to place our rebar and welded wire. In this application structural rebar was required and welded wire, 6x6 inch square, will be placed as a grid on top. This will allow the even attachment of PEX later.


Manifold and PEX Positioning
Once the rebar is in place the wire is zip tied over. This is also when we place our manifold. Careful thought should be put into where the manifold goes. Supply water, outside walls, easy access and a protected area are all concerns. Laying the tubing begins with placing PVC bends and attaching the PEX to the manifold. The tubing is then zip tied to the welded wire or rebar. The spacing of the PEX depends upon the desired BTU output.

Laying Out the PEX
Unreel the PEX, do not pull the PEX off so it coils like a phone cord. This will make things much more difficult and could result in kinks. A PEX un-coiler can be purchased or made if you don’t have enough hands.

Even Loop Lengths = Even Flow
Contouring to bump outs and irregular shapes is easy. The perimeter runs will dictate how this happens. The key is to have even loop lengths for even flow. Once you calculate your loop lengths cut the PEX and start your layout. Extra PEX can be put closer together on the edge. Small shortages can be compensated for by wider spacing in the center of the floor.

Finished PEX Tubing Layout
Here is a picture of the finished pattern. The loop lengths are even, spacing varies very little. Note the tubing is closer together at the edge, where heat loss is greatest. When creating a garage slab a thermal break should be used at the apron. We don't want heat sneaking under the door and outside.

Pressure Testing
The PEX is fully attached to the manifold and ready for pressure testing. There is more info on our site about pressure testing.

Pouring and Leveling the Concrete
Once the concrete is poured the screed process begins. We are not concrete experts, so we will not try to reinvent the wheel. Follow your concrete contractors instructions and level the pour. Note there are 1 inch PEX supply lines in the background. They will supply the water to the manifold.

**We rented afloat, making the work much easier. There are many options when finishing concrete. You should always consult a concrete specialist.

Trimming Extra Slab Shield
This close-up shows the slab shield corner and the extra slab shield to be trimmed. The foam is trimmed after the concrete cures. There are several caulking products available to cover the foam and prevent water, insects and anything else from getting into the foam.

Installing Pex Under Floor Options

There are many ways to install PEX under the floor between the floor joists. We will review four of them; heat transfer plates, hung, staple up and joist hung.

To properly install PEX we need to understand what happens to PEX when it is heated. PEX expands at a rate of 1.1 inches for every 10 feet at 100-degree rise in temperature. If the PEX is held tightly it will make noise when it expands and contracts. For under the floor radiant heat applications the temperature should not exceed 160 degrees Fahrenheit with heat transfer plates or staple up. The hung method can be run as high as 180 degrees Fahrenheit as it does not come in contact with the floor directly. This is the maximum water temperature you should use. The water temperatures should be set as low as possible to provide even heating for your comfort level.

First is the Heat Transfer Plates. They are made of aluminum and steel (aluminum is used most often) and provide the most BTU’s per sq ft of the four methods (24 BTU’s per sq ft) and allow for lower water temps for higher efficiencies with condensing boilers.

The extruded aluminum plates (C-Track) are the nicest and the most expensive. They are 4 to 4-1/2 inches wide and 4 feet long and approximately 1/32 inch thick. The extruded part allows the PEX to snap in sideways holding it securely and held in place with screws.

The other type of heat transfer plate is a stamped aluminum sheet. These are made of thin metal that look like flashing material. The sheets typically are 4-1/2 inches wide and 16 to 24 inches long (we sell the 24 inch ones). These plates have a stamped groove in them to hold the PEX up against the bottom of the floor (but not as securely as the C-Track) and are usually staples to the sub floor.

The extruded heat transfer plates are the least noisy of the plate method and only at higher water temperatures. The stamped plates tend to be the nosiest as the PEX rubs against the floor and plate when it expands and contracts. This tends to scratch the oxygen barrier on the PEX surface. Heat transfer plates can lead to uneven floor heating as they concentrate the heat directly above the plates.

The second is the Hung Method. The PEX rests on supports mounted between the joists every 2 1/2 feet and approx 1 5/8 below the floor. The PEX is laid over the top of them and zip tied to the supports. This method provides approx 18 BTU per sq ft.

One important advantage of the Hung Method is the PEX does not touch the floor (1” away) and allows for convective air currents to heat the floor evenly. This also means hard wood-flooring nails will not reach the PEX.

This is why we prefer the hung method (we installed in our own homes) because when the PEX expands it just sags up and down in the joist space causing no noise or damage.

The third method is a staple up using talon, standoff clamps or staples to attach the PEX directly under the sub floor. This is one of the least expensive methods and offers approximately 15 BTU per sq ft, as there is minimal convection around the PEX.

When stapling the PEX directly to the sub floor, the spacing needs to be approx every 2 feet to avoid noise. The staples are only 1/16 inch wide and, in our opinion, this is not enough support to keep the PEX from damage over time.

The forth method (which is not recommended) is to attach the PEX directly on the sides of the floor joists with talon or stand off clamps. The joists act as heat sinks and draw some of the heat away from the floor.

All methods require containment of the heated air between the joists (dead air space) so heated air will not be replaced with colder outside air. And the use of a small length of protection sleeve is to protect the PEX where it passes through the holes drilled in the joists. (It is recommended that you use protection sleeve whenever you pass through floor joists with any under floor installation.)

When heating within the framework of a building you need to caulk all the electrical holes, plumbing and chimney chases, around all of the band and rim joists, and any other area that heated air could escape. This is easiest with modern platform framing as the plywood sub floor caps off the heated air.

For older ballooned framed houses and houses that are sheathed with boards we do not recommend radiant heating within the joist spaces. When houses that are sheathed with planking the gaps in the boards allow the heated air to travel out of the joist spaces easily. This causes a negative air pressure with in the framework and draws in cold outside air.

Under floor radiant installations should have a reflective insulation, which helps contain the heated air. The insulation is positioned 4 inches down from the PEX and stapled against the joists. If the space is heated, the use of a secondary insulation is optional. If it is not heated, (like a basement), we recommend the use of fiberglass or high-density foam board below the foil.

Remember, it is very important to know the heating limits of the floor (25 BTU’s sq ft). The Staple Up method can deliver up to 15 BTU’s per square foot. The hung method can deliver up to 18 BTU’s per square foot and 24 BTU’s with heat transfer plates. If you try to deliver more heat than this you can damage the floor.

When the heat load required for a specific area is larger than the radiant floor can provide, supplemental heat is needed like radiators, wood stoves, or gas direct vent heaters.

What is PEX Tubing? Why should you use it for Radiant Heat?

What is PEX Tubing? Why should you use it for Radiant Heat?


PEX is an acronym for polyethylene, crosslinked. It is made to last about 200 years, but if you live for another 200 years and the PEX you buy is still in the floor and working - please give us a call - as soon as possible. PEX pipe is, however, the material you'll find all over Europe. The Europeans have been doing hydronic radiant floor heating with PEX since the early Seventies and there's a lot more of it there than there is here. PEX Tubing has a great track record.

PEX Tubing manufacturers have been taking the time to spell out the differences between their products. And there are differences in the way different companies make PEX piping. Knowing this can help you make the right decision when you're shopping for a PEX supplier for your radiant floor heating or plumbing system.

Most manufacturers start with a material called HDPE, which stands for High-Density Polyethylene. HDPE evolved from polyethylene, a material discovered by accident by a group of British scientists during the 1930s.

PEX differs from HDPE in that PEX has this special three-dimensional link between the molecules. It's this network of macromolecules that gives PEX such a fine memory for its original shape. If you kink PEX pipe, you can just heat it up and it will always return to the shape in which it was first crosslinked.

The linking of the molecules happens during the manufacturing process, and how a manufacturer chooses to make that happen affects the properties of the final product. The manufacturer can't link all the molecules together because that would make the PEX pipe too brittle. On the other hand, if they link too few molecules the material won't be any better than HDPE, from whence it came. They have to find just the right combination of linked and non-linked molecules.

There are different ways to get where they need to go, and from what I've learned, some ways seem better than others. Here are the principal methods manufacturers are using today to make PEX:

Engel-method PEX (also known as PEX-A) This is the stuff Tomas Engel brought into the world. Engel was the guy who invented PEX. He is a European scientist and he had nothing to do with the radiant heating industry when he invented PEX. What's important for you to know is that Engel-method PEX gets crosslinked while it's still in its melted form. The manufacturers do this by adding peroxide to the mix and then applying a tremendous amount of pressure and temperature to the liquid. What comes squirting out of the machine is PEX that's as clear as glass. As it cools, it takes on a darker color. The Engel method gives the pipe an essentially uniform distribution of the crosslinking sites throughout the material. This is the best way to make PEX pipe. It takes a while longer to do it this way, and this sort of PEX may cost a bit more.
HousePEX PEX-A Tubing is made with the Engle-Method - thus HousePEX PEX-A PEX is "PEX-A".

Irradiation-method PEX (also known as PEX-C) Irradiated PEX starts out as straight polyethylene tubing. As with other methods of making straight polyethylene, the tubing takes on a definite form during the extrusion process. With the irradiation method, the crosslinking takes place in a second process when the manufacturer runs the tubing through an electron beam cannon. The beam gets the polyethylene molecules so excited that they crosslink. This method can sometimes result in a less uniform crosslinking of the material. If it's not done properly, the outer layer of irradiated PEX tube can become brittle, but this is not a concern in a well-controlled process.
HousePEX PEX-C Tubing is made with the Irradiation-method - thus HousePEX PEX-C PEX is "PEX-C".

Silane-method PEX (also known as PEX-B) The big difference between this method and the other two methods is that with the Engel and Irradiation methods, the crosslinking consists of a bond between carbon molecules. With the Silane method the crosslinking takes place across silicon and oxygen molecules. These links are weaker than the carbon-carbon links that result from the other methods, and this may have an effect on the long-term chemical stability of the material. If we live long enough, we'll probably find out.

It's good for you to know the differences between these materials even though they all go under the name PEX. Let's face it, you're the one who's going to be putting the tubing under the floor.

In fairness, though, I have to tell you that none of these methods is a bad method; The American Society for Testing and Materials (ASTM) approves all three methods. However, in a world among "equals," it seems to me that some methods are more "equal" than others. Don't think of PEX as a commodity item. There is a difference.

And this is why HouseNeeds sells PEX Tubing manufactured with the Engel-method for radiant heat for floors, walls, and ceilings as well as your plumbing needs. We strive to offer only the best products for your housing needs.

Installing PEX Tubing Under Flooring

Click on the above link for a diagram

For Hung PEX Pipe (Slide Brackets, PEX Heat Transfer Plates or Staple Up Methods)


Installing PEX Tubing through the joists:
Drill (2) 1-1/2” holes in each joist as shown in Drawing A
Feed the PEX tubing through the hole (furthest from the sill plate) starting that particular loop in the last joist bay. PEX Tubing should be uncoiled off the top of the roll to avoid kinking.
The returning PEX Pipe goes through the holes closest to the sill plate.
Starting with the joist bay furthest from the manifold, grab the loop and twist 180°, then pull the PEX loop the length of the joist bay. Fasten the end of the loop in place or let it hang. Continue to work back toward the manifold (see drawing B).
This procedure applies for all three methods of attaching the PEX (Heat Transfer Plates, Hung Method and Staple Up). Please Note: Top of Slide Bracket (Hung Method) should be 1 5/8 inches below subfloor.
Foil Insulation is placed approximately 4 inches below the PEX tubing when done.
