What valves do you have at present? It is in the regs that all new CH

radiators have all got TRV's ( thermo- static radiator valves ) on
them, one ( typically in the hallway ) will have to have the TRV
removed, so the thermostat ( also in the same room ) can control the
CH sytem without fighting a TRV.

When you say a thermostat, aree you sayiny it is compulsory to have to
have roomstat in the one room which is not covered by a TRV? I'm about
to have a system installed and was intending to go for a towel rail in
the bathroom with manual valves, and no roomstats (all other rads with
TRVs) - does this design not cut the Part L mustard? Had a look at the
approved doc but can't find this.
