Thermostatic Radiator Valve's
 

any plumbers on o0ple recommend any and which to avoid?

going to use 15mm, 90 degree type, vertical head and not straight through

need to get 7 x 15mm & 1 x 10mm fixings

been suggested I use Pegler Terrier II

I just use my local plumbers merchants, half the price of B+Q

Drayton TVR4 are common and work well, seem to go very cheaply on eBay, new & buyitnow.

Drayton TRV4 are one of the best. We have used hundreds over the years and very rarely have had any problems
