Will a 40,000 btu furnace be enough to heat my 1375 square foot middle unit town house.
It depends on the size of the boards.
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.
The number of BTUs needed to heat a room can vary based on factors like insulation, ceiling height, climate, etc. As a rough estimate, you can use the formula: 20 BTUs per square foot for a room with standard ceiling height. Therefore, for a 60 square foot room, you would need around 1,200 BTUs to heat it effectively.
It depends on the width of the carpet.
1 square foot = 929.0304 square centimetres.1 square foot = 929 square centimetres
