Factors That Influence Heating Costs

The cost of operating any natural gas heaters system is determined by four factors, including the type of fuel, the cost per unit of fuel, the amount of heat provided per unit of fuel, and the efficiency of the heating system. The amount of heat is measured in British Thermal Units -- or BTUs -- while the efficiency rating room heater electric can be found by checking the annual fuel utilization efficiency. The University of Maine suggests using this formula to calculate heating costs: cost per unit times per unit/efficiency. This formula gives you the fuel cost of heat. The average home requires of heat each winter according to the U.S. Department of Agriculture
