What is an indirect fired hot water heater?
An indirect water heater uses the main furnace or boiler to heat a fluid that’s circulated through a heat exchanger in the storage tank. The energy stored by the water tank allows the furnace to turn off and on less often, which saves energy.
Do I need to flush indirect water heater?

At left is an Alliance indirect water heater from Burnham (also discussed below).
Where does the water come from in an alliance indirect water heater?
Look around the oil-fired hydronic heating boiler in the left of the photograph. This boiler is providing hot water that circulates through the heating coil inside the Alliance indirect water heater. We found water around the floor of the heating boiler not at the hot water tank itself.
How does a leak in an indirect water heater work?
Therefore a leak in the heat exchanger coil used in an indirect water heater will normally send building water supply water (potable water) into the heating boiler and its piping system, entering at the coil leak and passing into the piping that connects the coil inlet and outlet to the heating boiler.
Can a radiator drive an indirect water heater?
If, however, your home ranks among the relative few with hydronic baseboard, radiator, or in-floor radiant heating, when you install an indirect unit, the boiler drives both systems, heating the house and the water.
