  • I'm thinking of investing in a tado set up, we have a radiator that has a thermostatic valve in the living room but I'm not sure about the bedrooms. It's the bedrooms I want to be able to turn off during the day. Newbie question but how do I tell what the valve is and if compatible? We have these Honeywell valves in 3 of the rooms.

    Thanks

  • tarp set up

    You mean Tado?

    Most smart thermostats come with a whole bunch of adapters.

    Tado fit m28 x 1.5, which is the standard size of European lockshield valves

    Our place didn't have standard ones though, so we used adapters for a while.

    Until they turned out to be shit.

    So we replaced all of the lockshield valves in the house over summer - this is a pain, but very doable.

    To see what you have, you can unscrew the TRV (using the knurled bit there), and measure the threaded bit.

  • Haha, yup, tado not tarp, have edited.

    I thought the rads had to already have TDVs on them for them to be compatible. We're in a relatively newish house so hopefully everything will be standard fittings. Our last place was just a mix up and a total pain.

    It's a bit like buying bike parts, iso Vs JSI, left hand threaded/RH threaded etc etc.

    Explains why my parts box kept growing
