    The five TRVs arrived on time and were as described. They fitted easily but as the weather has been warm so we’ve not tested them properly, but I have no reason to think they will not work as expected.

    Struggled to find compatible TRVs for my old radiators, saw these and seller assured me they would fit. Ordered 1 to try, arrived a few days later, fitted OK, Ordered another 5 to fit remaining radiators. All arrived 3 days later, great service!

    Radiator TRV’s

    I had been looking for a TRV head to replace my old Landis & Gyr TRV heads, I ordered 4 to give them a try. These units came in good time and fitted not problem and they work well.

  • Most critical review

    Multi fit is not multi fit for me

    This product looks ok & probably is ok but the thread diameter is larger than my radiator fittings which are not that old. No mention is ever made of the size of coupling & I thought that as described as multi-fit it would be ok. So disappointed.
