If your radiators are getting warm or even hot though it is switched off in the tado° app, there may be an issue with your heating system - provided your Smart Thermostat / Extension Kit had been wired correctly during installation.
There is a simple test that you can do to find out what the problem might be before you call an engineer:
- Double check that both heating and hot water (if available) is switched off in the tado° app (mobile or web). If hot water is not controlled by tado°, then turn it off at your boiler or existing external programmer.
- Now wait for your radiators to cool down - depending on your home, this may take an hour or so, but it is important for the next step.
- Once the heating has cooled down, only turn on the hot water.
Wait for a while and touch your radiators regularly to check if they are getting warm.
The reason for this is that in most homes, there is one boiler that heats water for both central heating and domestic hot water, and there are valves that control where the hot water needs to flow depending on the demand.
Sometimes these valves can get stuck and the hot water will flow into either the wrong circuit (eg. heating) or both at the same time.
If only hot water is turned on, and the radiators warm up, then you need to get an engineer to examine your heating system - we can put you in touch with an engineer who can help.
