If you unfortunately have to face a problem using our Hot Water Heat Pump system, please check the following items, before seeking for professional help.
|Status||Considerable Causes||Action to Take|
|No hot water comes out of water tap
The temperature of hot water is too low
|Small or no hot water left in the storage tank.||- Stop using hot water and wait for about 1 hour
- Consider a change of the electricity supply off-peak mode (Length of power- supply hours may be too short for the water heating cycle to cover the hot water consumption)
|Air removing procedure from the heat pump system may be insufficient.||- Open the water drain plugs on the Heat Pump Unit to remove air from water circuit. (Be careful for burning)|
|Filter on cold inlet connector may be blocked.||- Check the filter and remove if there is any blockage|
|Water flow speed may be dropped due to the heat pump piping bend, blockage or crush.||- Check for any piping bend or crush and remove if any|
|Pipes may be frozen.||- If frozen area is found on the piping, melt the ice on the pipe and provide a heat insulation|
|Stop valve is closed.||- Open the valve|
|Air absorption is not sufficient due to a blockage on the evaporator.||-Remove the object blocking the air flow through the evaporator
(e.g. fallen leaves,grass, snow, etc.)
- Do not turn off the electricity supplied to the heat pump system even if you go away from home and not useing hot water for a long while.
- If the system is equipped with freeze protect heaters, also do not turn off the power supply to the heaters.
- Failure to do so may cause the pipes to crack, due to freezing.
For those problems not listed in the list above, an inspection provided by a skilled engineer is required. Please contact us
