if u tell me what make and model of boiler you have and measure the lenth and depth of all your radiators i can work out how big a radiator can be installed. Also let me know which are single panel, double panel or p+.

that would be a great help thankyou
my combi boiler is a BOSCH worcester 28CDI
the radiator size's are: 8 rads in total
2: 1000x600
1: 480x600
2: 400x600
1: 1440x450
2: 960x460

all rad's are single

im hoping to add a 1000x300 rad into a conservatory would rather fit a double but a single will do if need be what do you think?

kind regards

Hi Rambo sorry for the delay in getting back to you i forgot that i asked for the dimensions and not many people actually come back to a post but here gos

Your boiler is the rsf (room Sealed Flue) I hope as you said it was the 28cdi this has an output on the central heating side of
9-24kW (30,700-82,000 Btu/hr)

The size of your radiators have a btu size of (give or take 10 btus)

2: 1000x600 3519 each total 7038
1: 480x600 1759
2: 400x600 1408
1: 1440x450 not sure but roughly 4500
2: 960x460 3021 each 6042
o==
you have just under 21000 btus used so the boiler should be sufficient as the radiator you want to hang is only 3737 btus

So long as the pipework is not too long the boiler should cope well enough.
