Thermostatic Radiator Valves

Postby Morgan » Mon Sep 01, 2008 8:17 pm

I have just replaced all of of my old radiators for more efficient compact radiators with convectors on the back. I have found this forum excellent for problems i have encountered. however, my question is ... do I have to still balance the system with TRV's fitted. Thank you in anticipation

If the heat is not being evenly distributed - then yes. Balance using the lockshield valve, not the TRV.

This will probably be a daft question to most people, but I am re-furbishing a 3 bed detached bungalow and I have put in a new gas combi boiler. Do I actually need Lock Shield valves? What is there purpose?

lockshields are the valves on the end of the radiator that once set don't get used to turn the rad on or off unless closing off to remove the rad. these are needed so you can restrict the radiators that heat up too fast robbing larger radiators of heat, so you can balance the system and have it all heat up efficiently so yes you need them/have them.
