Heating warm, although off
Basically, the heater must be cold when you turn the rotary knob all the way to the right and it is at zero. If you then notice that the radiator is warming even though it is off, there are a few tips you should definitely try out. If the defect is not rectified quickly, this will affect your utility bill.
Reasons the heater is warm even though it's off
- First, you should check that your heater is defective at all. If you turn the gearshift knob all the way to the right, the radiator is off. The radiators in the entire house can also be switched off centrally. Many landlords initiate this in the summer months. If your radiator is still warm even though it is switched off, there is a defect.
- The cause is usually a defective valve. Either the valve is broken or it is incorrectly adjusted. If the adjustment is incorrect, the radiator cannot be set to 0, but remains slightly switched on. If the room is also very cool, maybe because a window is open, the heater heats up more than with a warmer air temperature.
- A temperature measuring device is installed in each radiator. This can also be the cause of the defect.
- The valve could be jammed. Unscrew it, you will see a metal pin behind it.
- The radiator could be set to frost protection. You can see the ice crystal symbol on the knob. If the radiator is set to this, this prevents the heater from freezing. However, the pipes can still be affected by frost. If the rotary knob is set to frost protection, a little heat is still emitted from the radiator. This setting is recommended in winter; in summer you should turn off the radiator completely.

Solution tips - how to turn off the heating completely
- If your heater is warm even though it is off, the valve may be trapped. Then simply unscrew it yourself and use pliers to loosen the metal pin located behind it. It must be able to move freely so that the valve works again.
- If the valve is not adjusted correctly or the temperature measuring device is defective, this must be repaired by an installer. Contact an installer and have this repaired. Otherwise you will have to spend more money on heating costs than you need to. That would be very annoying.
- Live at the rent, the landlord must ensure that the heating works properly. You then simply contact your landlord and he has to hire an installer at his own expense or repair the damage himself.
- You cannot carry out an exact hydraulic temperature adjustment if the heating system does not have a thermostatic valve with the option of presetting. Check this by unscrewing the thermostat head. You will need a pipe wrench for this. water cannot escape here. If you see engraved numbers on the valve insert, your radiator has a presettable thermostatic valve. If the numbers are missing, replace the thermostatic valve and then carry out a hydraulic balance. You can use the thermostatic valve to make a presetting according to which the flow of warm water in the heating system is restricted.
