High-Efficiency Boilers, Furnaces, Heating Systems

Boilers and Furnaces. The following features can help improve efficiency: Condensing: A condensing boiler or furnace extracts heat from the water vapor in combustion gases, getting more "bang for your buck" from the exhaust before it goes up the chimney. Condensing systems can achieve burner efficiency as high as 96%.

About Energy Kinetics Boilers

Basic conventional boilers provide DHW by passing cold water through a coil that is installed in the boilers' water jacket. This is extremely inefficient and virtually causes the boiler to run every time you run the hot water tap. To make DHW efficiently Energy Kinetics makes 40 gallons of hot water at a time and stores it in an insulated
