What is Indirect Water Heater?
An indirect water heater utilizes a separate heat source, typically a home’s boiler, to warm its water. Instead of direct combustion, a heat exchanger, often a coiled pipe within the tank, transfers heat from the boiler’s hot water or steam to the potable water. This design makes it highly efficient, especially when paired with an existing high efficiency boiler. It avoids the need for a dedicated burner, vent, or chimney. Its key significance lies in providing abundant hot water economically, leveraging the boiler’s capacity, and offering exceptional recovery rates for household use. Applications range from residential to light commercial settings.
