110,000 btu
Since British Thermal Unit deals with volume rather than area, we need to know the height of the ceilings. The original answer probably (and sensibly) assumes standard 8' ceilings. Hate to sound like a nitpicker, but many of today's homes have at least one room with a "cathedral" or vaulted ceiling. My previous home had "Saltbox" architecture; at one place in the great room (which comprised 1/2 the house's total square footage) reached a height of 42' sloping to 8' in front and 35' in the rear. The total square footage of the house was ~1700, where the cubic footage must have been almost 3 times that of a standard 1700 sf house.

A HVAC contractor would be the best person to ask this question to because they need to run something called a heat load calculation to determine the BTU number for your home.
Measure from front to back of house,then you multiply it bye 2 (both sides of the house).this gives you the sq footage of the house. Look at box and see how much is sq ft. Is in the box . Add the amount of boxes to the sq ft you got from the house.
Most houses don't use common bricks for the foundation. Concrete is more effective and commonly used.
You need 100W per square meter. 100W equals around 341.3BTU. 1 square meter are around 10.7 square feet. You therefore need around 32 BTU per square foot.
