The biggest share of home energy costs is accounted to home heating at 60%. If your boiler or furnace is more than 10 years old, it's probably a low-efficient model having a Annual Fuel Utilization Efficiency (AFUE) between 60 to 70%. i.e. It's only producing 60 to 70 cents worth of heat for every dollar you are spending.

There  are Energy Star natural gas equipment that can perform upto 97% AFUE (furnace) and the Energy Start boilers can perform at 85% or more AFUE.
