  • How to solve the problem occurring water flow fault when unit is running?

    You can solve the problem according to such points:1) Check whether the filter is blocked;2) Check whether the water flow rate is higher than the rated rate;3) Check whether the water flow switch is broken down;4) Check whether the controller input is broken down.

  • Why doesn't the compressor work when powered on?

    1) Please check the power source (lack of a phase or an error of phase).2) The compressor capacitor is broken down, change a new one.3) The compressor relay is broken down.4) The controller with no output, change a new one.5) The compressor is broken down, change a new one.

  • Why does the unit turn on and turn off frequently?

    1) Power pressure is abnormal;2) The refrigerant is overfull (let spare refrigerant out);3) Cooling system of condenser is not good (wash the filter).

  • Why doesn't fan work when the unit started up?

    The problem may result from such reasons:1) Check fan relay (if its broken, change a new one);2) Check fan capacitor (change a new one);3) Check controller output (if no output, change a new controller);4) Fan motor is broken, change a new one.

  • How to solve the problem that the unit makes terrible noise?

    The problem may result from such reasons:1) Fan motor noise (blockage or the fan capacitor is aging);2) Fan motor electromagnet noise (change a new one);3) Fan noise (change a new one);4) Compressor noise, please assure the right operation without exceeding its function.

  • The unit keep running, but with less heating efficiency, how to solve such problem?

    The possible reasons are as following:1) Leakage of refrigerant or a lack of refrigerant, please check the leaking point and vacuum again, charge the refrigerant with certain amount stated on the logo;2) Vacuuming or refrigerant-charging system blocked;3) Air flow system doesn t work well, please check evaporator and wash it if needed;4) Overfull refrigerant, please release the spare part;5) Compr...

  • What is the certification of the hot water heat pump do you have?

    We have CE and ETL certifications.

  • What is the hottest water the hot water heat pump could make?

    It is 60 degrees.

  • Why to install the condenser drainpipe?

    Because moisture or condensation can be a by-product of the PHNIX hot water heat pump depending on humidity and the run time of the heat pump. Condensate amount will vary according to these conditions.Since the heater has a condensate tube, a drain is a must and better close to the unit. The drain must be no higher than 36" above the floor (laundry drain is acceptable).

  • Whether the hot water heat pump could replace traditional water heat pump such as natural gas water heater and liquefied gas water heater?

    First, you have to consider installation and power supply. The PHNIX hot water heat pump requires 230V, 10amp electrical power to operate. Most natural gas or liquid petrol water heaters do not require electricity. To replace natural gas or LP water heater with a PHNIX hot water heat pump the current natural gas or LP supply line would need to be capped by a licensed plumber and the water heater n...

  • What is the range of ambient running temperature of the unit?

    It is among -7℃-43℃.

  • How much carbon emission will be decreased of the hot water heat pump?

    Operating a PHNIX hot water heat pump instead of a standard electric model could help a household avoid up to 62% of CO2 emissions on the grid from water heating.If 25% of households worldwide choose PHNIX heat pump water heater instead of a standard electric water heater, more than 4 billion pounds of CO2 emissions on the grid could be avoided annually, equivalent to the annual emissions of more ...

  • Where hot water heat pump should be installed?

    The PHNIX hot water heat pump should be installed in a clean and dry area, close to the place where most hot water needed is a plus; this could help reduce the wasting when water goes through un-insulated hot water lines. Because the units inhale air from the room to heat water, the room must be at least 10 x 10 x 7 (700 cubic feet) or larger. If the room is smaller than 700 cubic feet, the room m...

  • What will the unit perform suddenly be power off when running?

    The PHNIX hot water heat pump will not work without electrical power. When power is restored after an outage, the water heater will go through the dry fire process then automatically revert back to the original user setting.

  • What is holiday mode?

    This feature is used when the homeowner is away from home for an extended period and hot water is not needed. In this mode, the temperature will drop the water temperature down to 10℃and will use the most efficient heating mode to conserve energy. The unit will automatically resume heating one day before the program return, so that hot water will be available.
