Undersized kitchen/dinner/lounge radiator

sdsparks · Dec 4, 2010

I have a client with an open plan kitchen/dinner/lounge complaining it is freezing cold, basically a big room with double glazed patio doors leading onto the garden and 12 sky lights in the roof, the dimensions are 7.2 long x 4.5 wide x 2.45 high and all they have is a 4ft column radiator!

Because of the U value nightmare I have manually calculated Fabric & Ventilation losses, F1 & F2 factors and have came to a sum of 6350 watts of heat needed, I'm confident my calculations are correct.

The problem I have is I cant find a radiator rated to the number of watts needed above, so now I'm thinking two radiators but I only have the existing flow and returns to use as the floor is tiled, will the flow/return cope with this?

Any ideas or suggestions welcome

Thanks

Sam

Only a suggestion but I bet there's not enough in the budget ... fit an Aga or Rayburn!!

column rads dont give of a lot of heat i had someone insisting on them these were 500 wide and 5ft high there was 2 they got warm but that was only in a room 20 ft by 8ft what size pipe you using 10mm or 15mm is that metres or foot for your room size plus depends how far the boiler is away from the rad other rads could be getting the heat first especally if ye on 10mm

That room size is in metres! Not sure many of us could fit a 4ft column radiator in a room that's 2.45 feet high - not vertically at any rate!!!

(It's easy to mis-read something on a computer screen - much easier to see in real life - but I just couldn't resist the above bit!!! - sowwy!!)
