All the radiators in our house (except one, which I understand should be the one in the same room as the thermostat, but isn't) are fitted with Myson 2 way TRVs. On some of them the TRV seems to be faulty as the radiator stays off even when the room is very cold, and the heating system is on.
I've read the wiki article (//www.diynot.com/wiki/plumbing:thermostatic_radiator_valves_-_trvs) and I don't think the problem is with the valve sticking - as soon as I remove the head the radiator heats up. So far I've just removed the heads from all the radiators where we've had this problem and that's fine, but it does mean we've got no control over how high we have the radiator in each room.
Is my only option to buy replacement heads or is there another solution? Do I need to replace the heads with TRV ones, or is there a "standard" radiator control that will screw onto the the TRV valve?
If I do get new heads, are they a standard fitting? (ie will I need to buy Myson ones) We've had problems with 4 of 7 so far so I'm not that impressed with them. The house was new build 5 years ago and speaking to neighbours others have had problems too. Are the Myson TRVs just not very good, or have we just got a faulty batch?
Thanks for any help anyone can offer.
