Why is no hot water coming out of my Sanden Heat Pump?
- U
  umooreAug 4, 2025
  If no hot water is coming out of your Sanden Heat Pump's water tap, it could be due to several reasons. First, the temperature of the hot water might be too low; in this case, stop using hot water and wait for about 1 hour. Another reason might be insufficient air removal from the heat pump system; open the water drain plugs on the Heat Pump Unit to remove air from the water circuit, being careful to avoid burns. Also, the filter on the cold inlet connector may be blocked, so check the filter and remove any blockage if present.

What to do if my Sanden Heat Pump has no hot water coming out of the tap?

  Andrea CarlsonAug 12, 2025
  If you find that no hot water comes out of the water tap of your Sanden Heat Pump, it might be because the water flow speed has dropped. Inspect the heat pump piping for any bends, blockages, or crushes, and remove any obstructions you find. Also check if any pipes may be frozen. If a frozen area is found on the piping, melt the ice on the pipe and provide heat insulation.

How to fix a Sanden Heat Pump when no hot water comes out of the tap?

  Anthony HughesAug 25, 2025
  If your Sanden Heat Pump isn't dispensing hot water, ensure that the stop valve is open. Insufficient air absorption due to a blockage on the evaporator could also be the cause. Remove any objects blocking the airflow through the evaporator, such as fallen leaves, grass, or snow.
