Smart Radiator summer / maintenance / bleeding mode (leaving the radiator open)

sdmaino ✭✭✭

When summer comes, the valves should stay in open position. With the currently available modes, specially referring to "OFF", the valves stay closed. This is dangerous for the valves themselves, risk to get stucked, and for the pumps of the boilers which run periodically to prevent pump lock due to long inactivity.

    i have post a new thread with the same idea last year on the italian community

    Have 50 upvote, i try write here maybe the english section have more tado employee can implement this

    but i have just little hope, because some users say that is around 3/4 years they have to implement

    Did this for the same reason: have some more visibility.


  • It is also useful in case of several Thermostats. If by this system we are focusing of money saving, it is not acceptable to run heating while AC cooling the room under the winter target temperature.

    For radiator thermostats a stuck prevention would be also great. Open and close valves in every 2-3 weeks.

  • As winter approaches I've been doing the usual maintenance on my heating system, which includes making sure it's properly pressurised, all the radiators are bled etc.

    The problem is that normally tado keeps all the TRVs closed, which means actions like bleeding one radiator or pressurising the system don't properly propagate around the pipes. The only way to keep them open is to ramp the heating up, but then the system fills with hot water, and running the pump makes it easier for more air to be drawn into the system whilst bleeding.

    At the moment I'm getting around this by switching the boiler off at the mains, but I'd love a "maintenance mode" in the app which would fully open all TRVs and switch the boiler off, regardless of temperatures or heat requests. This would also be useful for things like draining or flushing central heating systems.

  • Another user had a similar request, to be able to fully open valves in the as it increases the longevity of the thermostatic valves.

    So it looks like there’s multiple scenarios where this is needed. Upvoted. :-)
  • I was suprised that this isnt a feature on Tado.

    Migo has this, but when I used Migo i had old school radiator thermostats that I could simply open fully during summer when the heater was off.

    So yes ...

    A summer/winter function which turns of the heating function of my boiler (or enters a summer mode) AND opens up all the valves.

  • Could this be a workaround:

    • Set your heater to 'off' for the heating (i can leave the hot water function on)
    • Twist off all TRV's, that way the valve remains fully oppen (correct?)
    • Set a new shedule preset (use of the three options that isnt in use for example) with a low temperature so there is no heat being requested.

    To be clear: I'd rather like to see this implemented as a software feature/setting in the app instead of doing this manually :)

  • Ive also reached out to tado and asked them to have this feature.

  • I asked the same question and got the following answer (Screenshot attached)

    If the Tado actuator causes an issue then just remove it temporarily. There is zero need to replace it with regular TRV.
    Once you remove the Tado actuator the valve will be fully open.
    Additionally, radiators should not be bled with the pump running as this can draw air in, rather than letting it out.
    Finally, all rad's have 2 pipe connections. TRV valve being shut *should* not prevent the radiator from being bled through the other pipe.
    Just make sure the system is fully pressurised (and remains pressurised while being bled) and any zone valves are hooked open.

    Different origin but at the end same feature. Let's upvote both !

  • Definately a needed feature

    Another workaround that I assume will work??

    Set all trv's to have no zone controller making each one an "independent trv" and therefore unable to call for heat. Open them all fully (maybe with the boost option) and neither the pump or the boiler should not switch on.

    But a feature within the app would be much better
