    What to do if my Sanden Water Heater has no hot water?
    • N
      Nicholas HillAug 1, 2025
      If no hot water is coming from your Sanden Water Heater, several factors could be the cause. First, the temperature of the hot water might be too low; in this case, stop using hot water and wait about 1 hour. Another cause can be a blockage on the evaporator, so remove any object blocking the air flow. Also check if the stop valve is closed and open it. If the filter on the cold inlet connector is blocked, check the filter and remove any blockage. The issue could also stem from frozen pipes; if you find a frozen area, melt the ice and provide heat insulation. Additionally, inspect the heat pump piping for any bends or crushes and correct them.

    Why is my Sanden Water Heater not producing hot water?
    • B
      Brian TaylorAug 16, 2025
      There are several reasons why your Sanden Water Heater might not be producing hot water. Insufficient air absorption due to a blockage on the evaporator could be the cause; clear any obstructions like leaves or snow. The water flow speed may be dropped due to the heat pump piping bend, blockage or crush, so check for any piping bend or crush and remove if any. Also, the 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 the water circuit, being careful of burns.
