  • 【Stable and comfortable temperature】Benefiting from the calculation and control of the heating power 1000/s by the chip, the temperature difference of the water can be precisely controlled within ±2°F.
  • 【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 5.1 GPM for 40 minutes, which is enough time to produce almost 200 gallons of hot water.

If installing a tankless water heater in a new house, its compact size makes it easy to install. Of course, we recommend that all installations are carried out in accordance with local building and plumbing codes by licensed professionals.
