Features

【Smaller size and better performance】It is only 1/4 the size of a 50 gallon tank water heater, yet it produces approximately 4.0 GPM of hot water through 90,000 BTU for both bathroom and kitchen hot water demand. The highly integrated components also provide greater safety from water pressure surges without the need to install an expansion tank.
【Fast and endless supply of hot water】The heat exchanger quickly heats the water to a maximum of 140℉ in a short time, and the hot water is quickly piped through to the shower and tap. No need to wait for the water temperature to heat up slowly like a tank water heater. After that it continues to operate at approximately 4.0 GPM for 40 minutes, which is enough time to produce almost 160 gallons of hot water.
