Indirect water heaters can be a more efficient choice without sacrificing the convenience of a storage tank. These systems use the main boiler or furnace to heat water that is circulated to its storage tank by a heat exchanger. The energy stored in the water tank allows the furnace or boiler to turn off and on less often, saving energy.

How do indirect water heaters work?
As the name would suggest, indirect water heaters work by utilizing an external heat source, typically an oil, or gas fired boiler. Once water is heated to a relatively high temperature (typically between 150 and 180°), it is pumped into a heat exchanger which consists of tubing, or a shell type design which contains domestic water.
