Dear all

Starting to get really confused
I was under the impression that now or I the near future both

Thermostatic radiator valves
And
Condensing boilers

Would be a prerequisite for a new installation.

Reading some details in FAQ the two systems don’t seem to be entirely
compatible.
The reason being that thermostatic radiator valves mean the water
temperature returning the boiler is higher than the optimum?

Thermostatic rad valve or some other method of controlling the room temp,
e.g. thermostat, is required now in every room, new build or refurb. You
don't really have to do this.
Fitters like to have TRVs in every room because it makes it easier for them
as they don't usually bother balancing the rads properly.
Condensing boilers will be required soon. When that happens you won't be
able to buy otherwise.

Modern boilers are able to modulate their power to fit the load so your last
statement doesn't apply.
Bear in mind that a condensor will probably not operate at full efficiency
except on the coldest days. Also with a condensor you will need those higher
output rads because the input temperature to the rads will be lower.
