  • I have one of these (I think) that is leaking from the pin at the top. Both myself and a gas engineer have tightened it but still leaking. I swapped the actual white bit for a tado one when it was fitted (by a plumber) about 2 years ago.

    Can anyone point me in the direction of a decent replacement? I don't need the white head or the lockshield, just the actual valve. I want to buy a few so a can put the 'old' thermostatic valves (replaced with Tado) onto the hall radiators which are currently just on/off.

    I would also like to swap at least one existing valve for one that points horizontally away from the radiator, rather than vertically. The Tado/rad combination means that the heat sensor decided it's 25deg because it's right next to the rad. Is this a waste of time?

  • Wickes locshield valves do the job, cost only a few quid, and are the right size for tado trvs.

    Have you tried the temperature offset in the settings of the trv?

  • Thanks, any chance of a link. I’m looking at lots of things that look really similar!

    I’ve set the offset, but it doesn’t really work for me for two reasons.
    A) my partner thinks the room is @ 16deg when it’s not and puts the heating on for no reason.
    B) when the rad is off, Tado thinks it’s 3deg colder than it actually is because the thermometer is reading actual room temp, then subtracting 3. When the rad is on, Tado ‘thinks’ it’s 22deg in the room while reading 25 then subtracting 3. But the far side of the room is barely 20.

    A separate stat in each room would be best but ££££. I would just like it a bit more true to life, rather than an expensive on off switch.
