How to Save on Heating Costs
Heating and cooling your home accounts for about 50 percent to 70 percent of the energy used in your home. Unless your home was built as an energy-efficient home, adding insulation will probably reduce your utility bills. Even a small amount of insulation–if properly installed–can reduce energy costs dramatically

HOW INSULATING YOUR HOME SAVES MONEY

The coldest part of your house in the winter and the hottest area in the summer is the attic. For this reason, it's important your attic floor have adequate insulation to prevent cold or heat moving down into your home. Having inadequate insulation or even worse, having no insulation in your attic can be expensive. In fact the Department of Energy estimates that having no insulation in an attic can add 30% to a home's energy costs, and with the average cost of heating a home over $1500 per year that adds up pretty quickly.
 !    Finding the R-Value
The R-value changes because of the type of heat you use and where you live. It also changes between new and existing homes. To find the recommended R-value for the area of the country you live in, contact your local electric company or gas company. You can also find the recommended R-value by zip code and heat source at the Department of Energy Web site, www.eren.doe.gov
