we are renovating our house - putting in new rads, windows etc. One problem is our hot press. The current cylindar is not insulated and we are considering replacing it with an insulated cylindar (possibly stainless steel) to reduce heat loss. Problem is - how do we keep heat in the hot press to air clothes etc? do we need to put a radiator in there? Its a approximately 3ft deep by 8ft wide and is under the stairs? any ideas?
