A fairly powerful 35kw combi has been installed. Radiators all
perform
as expected with no cold spots on any of the panels.

controls are in the main hall on the ground floor. Setting
the
thermostat at a fairly reasonable 20c results in the boiler

constantly, never reaching the 20c setting.


I have a Jaguar boiler in one of my flats, and you can set it for a
variety of Kw outputs.

What is the make and model of your boiler? Whilst it may have a max
setting of 35Kw, it might be set to much less.
