A high efficiency heat pump can deliver 50-75% in energy savings compared to traditional energy sources. If you have a heat pump as heat source in your home, we have some general advice for you, before entering the cold season.
Here are 5 simple heat pump troubleshooting steps to help you achieve the best heating for your household during the cold season. Most of them you can do yourself in a matter of minutes!
Step 1: Check the brine level
It’s essential that the brine circuit is always filled with the correct fluid levels otherwise the heating installation may become damaged. The fluid level may also vary depending on the temperature of the heat source. Under no circumstances must the fluid level be allowed to drop so far that it is no longer visible in the expansion tank. If the brine level is too low please contact your installer.
Step 2: Clean the brine circuit strainer
The brine circuit’s strainer must be cleaned twice a year. To clean it: Switch off the heat pump; Remove the insulation around the filler cock; Turn the shut-off tap (A) to the closed position; Unscrew the cover (B) and remove it; Remove and rinse the filter (C); Reinstall the filter; Check that the O-ring (D) on the cover is not damaged; Screw the cover back into place; Turn the shut-off tap to the open position; Reinstall the insulation around the filler cock; Start the heat pump.
Step 3: Check the water level of the heating system
Check the line pressure of the heating installation once a month. The external manometer must have the correct pressure. The pressure of the heating installation might differ from country to country but the most common setting is between 1 and 1.5 bar. If the value display is below 0.8, the water must be topped up. If the heating system pressure is too low or you are not aware of your heating system pressure settings please contact your local installer.
Step 4: Clean the strainer for the heating system
The strainer must be cleaned twice a year. Have a cloth ready when opening the strainer cover as a small amount of water usually escapes. To clean the strainer: Switch off the heat pump; Turn the shut-off tap (A) to the closed position; Unscrew the cover (B) and remove it; Remove and rinse the filter (C); Reinstall the filter; Check that the O-ring (D) on the cover is not damaged; Screw the cover back into place; Turn the shut-off tap to the open position; Start the heat pump.
Step 5: Switch operation modes
In the OPERATION menu you can set the operating mode of the heat pump. Please make sure that before the heating season arrives your heat pump is in AUTO or HEAT PUMP mode.
When changing operating mode, confirm your choice by pressing the right button once. The asterisk will move to the selected operating mode.
