What is an indirect water heater?
An
indirect is a storage tank with a heating coil built inside the tank. Hot water
from any hydronic heating boiler is circulated through the coil inside the tank
to heat all the water in the tank. The unit is piped like any other heating
zone.
Why use an indirect water heater?
An
indirect provides abundant hot water, low operating cost, and long life.
Abundant hot water
The
Model 40 takes the full output of a 150,000 BTU boiler giving you over 150
gallons per hour of hot water @ 90 degree F rise, continuous! This compares to
only 20 gallons per hour for a typical 4.5 KW electric water heater, and only
33 gallons per hour for a typical gas fired water heater. The Model HF-40 1st
hour rating is 190 gallons. For an electric water heater to produce 190 gallons
1st hour, it would need to be a 187 gallon tank!
Low operating cost
Increased
boiler on time increases boiler efficiency, and since there is no center flue
like gas and oil fired water heaters, standby losses are extremely low.
Operating costs of 50% less than an electric water heater are common.
Long life
No
direct flame reduces lime accumulation and there are no electric elements to
burn out. The units are all stainless steel construction. If you are installing
or updating a hydronic heating system, or have an existing hydronic heating
system, the indirect water heater is the right solution every time! Say goodbye
forever to hot water shortfalls and high electric water heating costs.
