What is an indirect water heater?
An indirect boiler uses the firebox or main boiler to heat a liquid that circulates through a heat exchanger in the storage tank. Due to the energy stored in the water tank, the heating has to be switched on and off less often, which saves energy.People are also wondering what the difference is between a direct and indirect water heater.A direct combustion boiler can be heated with propane, oil or natural gas and has its own burner. They are more energy efficient than an indirect boiler because it heats the water. The indirect water heater relies on the stove or water heater to provide the necessary heat to the water.Does the indirect boiler also save money?
Indirect water heaters use an existing heat source for electricity and can therefore save a lot of money in the long run. They require less maintenance than a direct model because they have fewer parts and often have better insulation so you don't need a hot water cover.Also, do you know how long an indirect water heater will last?
