    Quiet towel radiators?

    Anyone managed to fit a towel radiator that doesn’t ping and groan as the heating comes on? I have fitted loads, cheap and expensive they all seem to make noise.

    Programmable TRVs for cast iron radiators

    Does anyone know of programmable TRVs that would not look out of place on period cast iron radiators? Even finding regular TRVs is tricky, all the ones that "look good" seem to be very expensive and very good quality.

    Air / Blowing / Whooshing Sound in All Radiators

    I hear a noise in all of my radiators. The higher the TRV setting the louder the noise gets. If I turn the TRV down to a low setting the noise goes away, presumably because the radiator is no longer heating up. The noise sounds like air moving around the system, although it's very loud. It...

    Previously had a problem with noisy pipes and the forum suggested replacing the three way valve which has now been done. Before doing that the noise had stopped though the hot water was very hot and turning the boiler thermostat down didn't make much difference. As mentioned the new three way...
