  • How does the Paloma PH-28R Tankless Water Heater works ?

    - Set temperature of hot water on the remote control. The computer will detect the incoming water temperature and calculate necessary heat to achieve set temperature. Heated water temperature will be monitored upon exiting, in case adjustments are needed.

    - The electronic system detects temperature of incoming water and activates the burner as water flows through the controls, heating it instantaneously as it flows -and only when it flows- through the highly efficient heat exchanger. There is no holding tank with reserve water.

    - Digital setting allows you to choose anywhere between 100°F and 120°F with Bath Control (between 100°F and 140°F with Main Control) . And since it is electronically controlled, it maintains the same temperature.

    - This water heater can deliver 288 GPH (gallons per hour) at 70°F temperature rise. For example, if you wish to have 120°F of hot water when the incoming water is 50°F , you will get 288 gallons of 120°F (50°F + 70°F) hot water per hour. If the incoming water is warmer, you will get more than 288 GPH.
