You take the size of your home in square feet and times it by how many rooms you have. A 70,000 BTU furnace will heat a house 1600 square feet.
I would say a 40,000 BTU furnace could big enough to heat a 400 SQ ft house, but where have you found a 400 SQ Ft house?
Heat load calculations need to be conducted for home to determine the proper size furnace. There is no simple answer to this question. There are a number of factors that can effect what size your furnace should be. Example: square footage, duct work size, insulation factors, windows etc. I recommend having a heating professional look at your home and conduct a heat load calculation. Over sized and under sized furnaces can cause you number out problems in the long run.
