Lower cost and maintenance are only some of the many benefits with this option. Indirect water heaters are efficient and easy to install with no additional upgrades required.
The indirect hot water heater as the indirect-fired system uses a boiler-based space heating for domestic hot water heating.
The water inside the insulated storage water tank is heated by the boiler, indirectly, while fluids are kept separate; they are not allowed to mix. Thanks to the insulated storage water tank, energy inside is kept longer while the furnace or boiler operates less often.
The indirect system permits hot water production year-round in great quantities and typically at a much higher efficiency than conventional water heaters. The indirect system is tied into your home’s space heating system and it will heat the water even if there is no need for space heating.
Continuous use of the boiler for heating domestic hot water is very good for the system as it prevents costly deterioration which occurs when the boiler is idle for long periods.
During the winter, when the indirect water heater is used for the home heating, only a small fraction of the heat is used for domestic water heating. In summer all of the heat is used for hot water preparation.
Indirect hot water heater systems can heat water by using natural gas, propane, electricity, oil or solar energy. Heat pumps, gas or oil-fired burners are used as the source of the heat.
