I have a 1980's 3-storey house. ceiling to ceiling height per floor is 3050mm (yes, I know that's a lot, over 10 feet). In the centre of the house is the hall and stairwell. The hall is 2000 wide and 5500 long, with a part glazed wooden door at each end, and an open porch at the front. Also on the ground floor next to the hall are an unheated but draftproofed and insulated integral garage, an unheated utility room, WC, shower and spare room. The floor is uninsulated concrete. The interior walls are tri-wall dense concrete blocks.
Although the house is well heated and insulated, you can see that the hall is always going to be the coldest part. It has a 1200 x 700 single rad, but of course the heat rushes up the stairwell to the upper landings which are comfortable.
I am wondering if a long, low rad would do any better, or if I should be thinking about floor heating. I am thinking that a large surface at a modest temperature might not lose all its heat up the stairwell.
I don't want to use a fan heater in the hall if I can help it.
What ideas?
