Hi Lemonade
Can you tell me if TRV's are a direct replacement for ordinary radiator valves and are those that can fit on either flow or return ends of the radiators better than dedicated valves. If not, are you able to explain how to determine which is flow and which is return?
Many thanks

TRV's
Hello Tony
Yes TRV's are a direct replacement of standard radiator valves. There are many versions of TRV's, however you can get many TRV's which offer a bi-directional flow capability. Bi-directional valves are normally better than one way types. They are more accurite by use of a wax sensor instead of liquid. The price of a Bi-directional valve is normally more expensive though....but often worth the extra. To find out which pipe is flow or return:- If you know where the pump is, trace the pipe from there as this will be the flow. But usually the main valve on the radiator is the flow.
Try looking online at screwfix.com as they offer numerous valves (amongst many other things) at very reasonable prices.

To add:
It's good practice to keep at least one radiator on the standard valves, typically bathroom or hallway ones. Known as a 'heat leak', it gives the hot water somewhere to go -ie: away from the boiler, prolonging the life of the burners/heat exchanger.
Also, do not use a TRV in conjunction with the room thermostat (usually the hall rad as mentioned above) as you will need the room stat to have ultimate control over (that part) of the central heating system. You don't want the two controls arguing over how warm/cold it is!
Finally, keep the room thermostat! It's a requirement of Part L1b of the Building Regulations (Conservation of Fuel & Power (Existing Dwellings)2006)
If there are any problems, I would recommend you consult a qualified/competent plumber.
All the best.
