This could be more involved than the subject header suggests!
I am refurbing 1970s bathroom and intend to replace the radiator.
Currently there is a single panel convector rad installed 450 high 1000 long
(Stelrad K1 type I think).
My questions are as follows:
1. I have installed an extractor and wonder how much the radiator size
should be increased to compensate for the air removal.
2. Mounting the heating source vertically (as in a towel rail) would appear
to be self defeating, as a proportion of the heat is being applied at the
top of the room rather than at occupier level. The radiant heat effect felt
by the bather must be partially lost. Has anyone felt a "loss of comfort"
due to this vertical rather than horizontal trend? Should a ladder type
radiator be oversized to allow for this?
3. Are Stelrad's ladder towel rails any good?
4. Bearing in mind the lack of head between the header tank and the top of
any vertical radiator (Stelrad state minimum 600mm), do they function as
well as a radiator? I am thinking particularly about water flow around and
therefore heat distribution from the total surface.
5. Any good alternatives to Stelrad?
