Hello everyone,

We have a triple (k33) stelrad (i think) - can't find another make that makes triple depth, so assuming its stelrad.

Radiator is 50cm wide and 60cm high.

Boiler Ideal Classic FF250 set to 5

Hall is 4.1m (L) x 1.8m (W) x 2.5m (H)

On Specs its says delta 30 = 615W
delta 40 = 894W
delta 50 = 1195W

We have no radiator in small kitchen 2.8m x 2m

so no heat to help out that end of house

Can't get temperature in hall above 61 which seems far too low

What KW should I have for adequate heat 65+

Anyone tell me what out my current radiator is?

House 1924 semi

Thanks in advance

according to Stelrad specs your radiator is 1195 watts / 4077 BTU.

I have a similar problem in my house, it won't really get above 17c

also consider how much heat is being lost through draft doors / windows etc and also if your radiators are correctly balanced
