Malfunction in heat or cold delivery:
Determine if there is a malfunction in some or all spaces in the heat or cold delivery. If the malfunction occurs in part of your home, heat is still being delivered to your home but not to all spaces. This indicates a malfunction in the indoor installation, such as your (room) thermostat, controller, or a component of your floor distributor. The ownership boundary indicates who owns these components in your home.

Check if the thermostat is set correctly. You can temporarily set the desired temperature higher or lower on the thermostat. Ensure that your thermostat is set to request heat. This allows you to check if the temperature in your home changes after some time.
Check if the thermostat batteries need replacing. The thermostat indicates when the batteries need to be replaced.
Is your heating system still not warming up?
Find out if your neighbors are experiencing a similar malfunction. This could indicate a collective malfunction. This information is crucial for promptly and effectively resolving the malfunction.
