What type of heating system would you recommend?
I always had the impression that hot water baseboard heat was the best, or the modern equivalent, radiant floor is the best. Since it does not warm by moving air, it does not dry out the room as bad as forced air.
Radiant won't mess with furniture arrangements, whereas base heat may keep some items off the wall. Electric base heat and forced air may yank furniture placement too. Unless you don't mind the inefficiency of the system it creates. If you block electric base heat with furniture, that is not only inefficient, but a fire hazard too.
