I live in a fairly large house that is over 3 stories and has 22 radiators. The house is approx 8 years old and has a condensing boiler (Potterton) and a Grundfos 15/60 pump with a microbore sealed CH system operating at 1.5 bar.
Last year i put in some bigger radiators as the original house builder had undersized them(fairly normal of them apparently) Whilst the house is a lot warmer, it still does not heat up as quickly as i would like. Does anybody have any advice on the following :
1. The central heating pump speed. This is currently set to 2.
2. Getting bigger radiators - Should i just get some larger radiators with the view that the place will heat up quicker as by definition the rads are bigger.
3. TRV valves. I have noticed a couple of the rads in the house have the TRV valve and lockshield valve on the wrong ends. I have read somewhere on the internet that the TRV valve on the wrong end can cause problems in that the water pressure is not enough to lift the ball in the valve. The rad in question is the 'slowest' to heat up ?
4. A lot of rads seem to be a lot cooler at the bottom than the top. I know there is no sludge in the system as i have checked. Could this be because i have shut the lockshield valves down on some to almost closed (not even open 1/4 of a turn !) ?
Thanks In advance for your valued views/opinions
