Natural Gas and Oil Heating Systems

Install a Carbon Monoxide Detector

Carbon monoxide (CO) detectors are highly recommended in homes with fuel-burning appliances, such as natural gas furnaces, stoves, ovens, and water heaters, and fuel-burning space heaters. An alarm signals homeowners if CO reaches potentially dangerous levels.

If you plan to buy a new heating system, ask your local utility or state energy office for information about the latest technologies available to consumers. They can advise you about more efficient systems on the market today. For example, many newer models incorporate designs for burners and heat exchangers that result in higher efficiencies during operation and reduce heat loss when the equipment is off. Consider a sealed combustion furnace; they are both safer and more efficient. Check the shopping guide for additional information on how to understand heating system ratings.
