Thanks for all your help, have gone with 2 rads

We've just had a new kitchen/diner extension built with an area size of 18ft x 16ft, we only have 1 wall available to hold a radiator are we better off with 1 large rad or 2 small rads or does it make a difference as long at the BTU output is sufficient. Thanks for your help.

Finally managed to resolve all problems we were experiencing!!! and thought I'd post the solution. Whilst staring at the boiler/pump waiting for inspiration, I noticed an anti-gravity valve in a section of pipe above the pump, I removed the valve and found it was full of debris and as such...

I have checked the entire system (incl. loft and airing cupboard) and there is no bleed screw cap on a vertical bit of pipe. All I have found is lots of draining points (i.e. above boiler, below pump next to a couple of rads and in the airing cupboard next to cylinder) Should I drain and...

Have hunted high and low for a bleed screw cap on a vertical bit of pipe with no success - any idea on where it might be located? I have turned off all but one of the (cold) rads, the pump is on 3 and just switched the heating on.

No we don't have this pump - our pump (DAB) is an in line pump next to the boiler downstairs. Does this help??

I think its a gravity fed system (i.e. there is a tank in the loft) - is this enough info? (it's a Potterton 'profile' boiler) It must be pretty obvious that central heating systems are not my strong point!

Thanks for the advice, found the similar question and the suggestion was same as yours - bleed the pump. I tried this and there was no trapped air - clear'ish water came straight out. Any other ideas? Any/all help much appreciated. :?

Help please! Just replaced 1 rad in hallway, when system turned back on 4 out of 7 rads are stone cold. 3 rads which work are first in the system, 2 upstairs and 1 downstairs. I have tried: 1) bleeding all rads with pump off, fairly sure all air is out of rads. 2) checked pump when...
