WATER HEATERS Q: What is an indirect-fired water heater?
Indirect-fired water heaters use the burner from your boiler to heat domestic water as well as water to heat your home. A coiled pipe is installed inside your boiler, where the hot water in the boiler heats the tap water flowing through the coil. In the winter, this results in huge water-heating savings or virtually FREE hot water. For homes with heavy hot water use, you can also install a separate insulated storage tank called an aquabooster for greater economy.
