Most heating systems use types of fuel

Types of heat exchangers fuels

Most heating systems use either combustion fuels--natural gas, propane, oil, or wood--or electricity. It is possible to choose a combination of these conventional sources, or even other alternatives, such as solar energy. (Solar energy options will be discussed in detail in a future article.) Energy prices can vary greatly from region to region, and in many areas natural gas, which must be distributed by pipeline, is not available.
Check local prices to see if energy will be saved by switching energy sources or making modifications to employ more than one energy source. Table 1 gives the energy content for the various energy sources, per unit in which they are commonly sold. It also provides spaces to enter the local prices of energy sources available in your area. Table 2 lists the typical seasonal efficiency of common heating equipment used with each energy source. Use the information in these tables and follow the Heating Cost Worksheet to determine savings in energy cost from switching heating equipment.
