We live in a Block with a communal heating and hot water system.

Some have previously replaced their radiators and have TVR's.
To my very simple mind I'm not convinced that it will work.... but I
will soon be corrected. At the moment if I have a valve full on or turn
it down to barely on the radiators stay at the same heat.

It seems to me if the radiator doesn't cool down the valve isn't off.

When we moved in the valves were corroded and did not turn. We had them
replaced when the new boilers were put in two years ago. When off the
rads go cold but any on position gives out the ame heat.
TRVs should cut down the costs - you won't get people having to open the
windows to control heat.

That was the first thing we noticed when we moved here, most poeople
just opened windows to cool rooms down.
