What size Radiator
6 Answers
We have just moved from a house to a bungalow and the front room is very cold even with the radiator on full, and i was thinking that the rad could be too small for the size of the room (which is big) could anyone tell me in laymans terms how do you determine what size rad should be installed, just in plain language please, height and width in feet and inches and whether it should be double or single panel.
Thank you in advance.

As someone else mentioned on here the other day, there seems to be a website for just about everything these days:

However, you may need a plumber (or Heating Engineer) to check that your boiler is up to the job of providing the extra heat.

If the rad is hot yet the room temperature still does not get up to want you were expecting, the rad is not big enough.
The sort of website Count links you to are fine, though remember that it will make a general assumption about the thermal performance of your room (the amount of insulation in the walls and the ceiling if the roof is immediately above it.
One can trade-off a smaller dimensioned double radiator for larger single one - the radiator calculator programme will do that for you. Many people prefer to fit doubles because one can get the same thermal performance in a smaller sized rad - taking up less room on the wall.

Apologies to Bob for hijacking your thread. Builders mate, can you advise me please about "bleeding" radiators. Is there a special sequence in which they should be done (e.g. nearest the boiler 1st or last?) or doesn't it matter?. Sorry if this sounds like a really stupid question. Thank you. Apologies again to Bob
Heat input requirements are complicated, taking into account all losses due to wall and ceilings, windows, temp needed, etc. There are calculators, which I use. Potterton do a good on online.
A large room should preferably have radiators on opposing sides, and underneath windows to give a heat check.
