Why are my radiators cold in my DeDietrich Heat Pump?
- T
  Timothy DominguezJul 27, 2025
  Your radiators might be cold due to several reasons: * The heating set point temperature might be too low. Try increasing the room temperature set point, or if you have a room thermostat, increase the temperature on it. * The heating mode could be deactivated. Make sure to activate the heating mode. * The radiator valves may be closed. Open all the valves on the radiators connected to the heating system. * The heat pump might not be operating. Check that it is switched on and inspect the fuses and switches on the electrical installation. * The water pressure could be too low (less than 1 bar). Top up the system with water.
