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.) |
||
Caution:
