Boiler : Vokera Linea 25HE
Wireless Programmable Roomstat
I seem to have having major issues getting rooms up to a desirable temperature since moving into this flat.
It's an old 1920s tenement style building (ground floor 1 bedroom flat) with very high ceilings. Thick brick walls external and internal, uPVC double glazing.
I have the roomstat set to 21 for evening (comes on at 5pm, goes off at 10:30pm), overnight/during day set to 15.
So far i've never seen the roomstat hit 21 by the time 1030pm arrives (or at any other point during the evening). Usually sitting at around 18-19. So after being on for 6 hours it's never reached the desired temp. Rooms are always feeling on the cold side.
Rads are always hot to the touch during the peak time. TRVs are set to full on all rads.
Overnight when it's set to 15 the boiler is constantly kicking in for some minutes then going off again. I assume because it getting the temp back up to 15 then turning off, then the room temp is dropping quickly and thus the loop continues. The boiler is in the bedroom so this continual on/off loop is not great for sleep. I've had to set it so the boiler is off for heat overnight just to get a decent sleep.
So what is the issue here? Is the boiler just not up to the job? Are the rads too small for the rooms?
