: I did those heat loss calculations for first floor and the total btu is 60381 for first floor.
*** that is a very BIG first floor. As it has no ceiling loss at all, all the heat is going out the walls, windows and floor, as the floor doesn't lose much heat, unless it is over open pilings, the heat is leaaving the walls and windows. With ordinary insulation that means you have an average of 700 linear feet of wall, which is a building that is 150 feet by 150 feet. Even if it has NO insulation it would be an 80 by 800 foot building.
Assuming the other floors are roughly the same, the total btu is about 180,000 btu. what type of device do you recommend installing at the steam boiler (I'd like to keep the steam boiler, as converting this house from steam to hot water will take about 3 years), or do you recommend replacing the steam boiler (if it makes a difference)
*** The upper floor would have MORE heat loss because it has a roof to lose heat as well. A middle floor would have slightly LESS. Incorrect assumptions lead to incorrect results.
If you have THAT much heat loss, insulate the place first and then change to a water system; the energy loss would be astounding.
