Hi

Took delivery of nine radiators today which are being installed next
week by a local central heating guy. The problem is 4 of the
radiators are chunky at 9.5cms in depth. Is this a usual size? The
other radiators are not exactly svelt but its the 4 chunky ones I'm
concerned about. Are these likely to be cheap radiators? Is that why
they are so big? None of my rooms are particularly big. I'm going to
speak to the guy tomorrow but wouldn't mind some opinions first.

I assume your central heating guy has selected the outputs. Read up here...

The size of a radiator is determined by the required heat output. I presume
the fat ones are double panel rads, with one or two lots of fins between the
panels? Assuming your installer knows what he's doing, he'll have chosen
appropriately sized radiators. If you want single panel rads (which are
slimmer) they'll need to be a lot bigger in height or width. Maybe you're
limited for available wall space in some rooms?

If you need a lot of heat, you need a lot of surface area. Price doesn't
really come into it.

If the guy is starting from scratch it probably that he is working to a
design using lower radiator temperatures to maximise boiler efficiency.
hence the need for double panel double convector units which are just as
big if they are expensive 'designer' styles as the bog standard units.
