THE TWO TABLES shown may be used to arrive at very approximate comparisons for fuel consumptions, relative to the home being well insulated with, say, two inches and a half fibreglass in walls and ceilings, metal roofing on sacking and a concrete slab floor (not insulated). .The tables are based on British figures and should be used as a guide only—the capacities of any heating system may be obtained, together with running costs, for various conditions, from heating manufacturers. It may be readily seen that with our 1000 sq. ft home, the requirements very approximately could be 38,000 units of electricity; 850 gallons of fuel oil; 5.4 tons of bituminous coal.
