Radiators and pipes making noise since installing Tado

Hello all,

Since I have installed the Tado system my radiators and pipes are making a lot of noise when they are being heated. Before we installed Tado we didn't hear a thing.

At first I thought it had to do with air in the system so I bled out everything several times but the noise continues. Perhaps it has something to do with the pressure in my system? Before I installed the Tado system all the radiators were open, now, most of them are closed all the time and only the radiator requesting heat is open. However, the pressure in the system is currently 1.9 bar when cold which is within the suggested range of 1.5 - 2 bar.

What could be the cause of this noise? And more importantly, how do I fix it?

Thanks in advance!

  • The noise is probably due to pump speed. It’s very likely that you have a water pump set to a fixed speed to push the water through all the radiators at once. Now you are using the same speed with fewer radiators open to the flow of water. You probably need to make some adjustments, but what you do depends on the type of pump installed.

    This article may help to understand the different types of pump.

    The static water pressure in your system will have minimal effect on the noise.
