We live in a Block with a communal heating and hot water system.
It has been suggested that residents at their own expense have TVR's
fitted to their radiators to cut down on the communal heating bill.
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.
If everybody fits and correctly adjusts TRVs, it will cut down the heat
used and the (presumably shared) heating bill.
However, it's a bit like global warming - it relies on *everybody*
taking suitable counter-measures, or it doesn't work equitably.
If only *some* people fit TRVs, they will potentially reduce their own
comfort levels whilst continuing to subsidise the high energy
consumption of those who don't!
Irrelevant, but in some council-run district heating schemes each
dwelling has a device on the wall that measures the room temperature and
this is used to calculate the bill for that dwelling. So the residents
drape bags of frozen peas over the device.
A very common misunderstanding is that a TRV is a *radiator* thermostat.
It is not - it's a *room* thermostat.
The radiator will variously go hot/warm/cold, as the TRV maintains the
The big problem with communal heating systems is that people just throw
the windows open when it gets too hot. With my home automation, the
heating in that zone is switched off if an outside door or window is
opened for 5 minutes or more.

I spotted that one before installation, so when the time
came I fitted them on the return side of the radiators so
that the sensor is horizontal and a tad further away from
the heat source. Works very well.
Also to the OP remember to leave one radiator without a TRV
so that some water can always flow through your system
(although I guess this applies more to a single domestic
installation.) The bathroom is the best option.
The bathroom towel rail (no Rad there) works off the hot water system.
When the new boiler was installed I was going to get new radiators
installed. Only three out of eight contacted from the local Checkatrade
directory wanted to come to quote. They scratched their heads and did
not understand how they would do it. I took them next door to a
neighbour who had previously replaced her rads replaced and had TVR's.
They evidently understood then. By the way we have parquet flooring
under the carpets if that makes any difference.
Two did not want to do it. Silence from the third. Eventually an E-Mail
to him produced a quote of over £3k for three radiators and another
Grand if we wanted an additional one in the hall.I did not bother
