The US Department of Energy is currently providing funding to promote a consumer rebate program for qualified ENERGY STAR appliances. These rates have increased since the start of the program in April (see the Liberty Homes blog entry dated 4/21/10).

In the state of Pennsylvania, the NEW savings range from $250 - $1,000 on ENERGY STAR gas storage or tankless water heaters, oil or gas furnaces, and oil or gas boilers purchased after August 2, 2010. Those purchased between April 21, 2010 and August 1, 2010 will receive the prior savings of $100 - $500.

There are specific requirements for eligible products so before making a purchase, please confirm funding and requirements at www.paheatingrebates.com. As of August 24, 2010, 22% of the estimated rebate funds remain.

“R-value” is a term that measures the insulation properties of a material. For example, fiberglass insulation is measured by its R-value.

The energy efficiency of windows is measured by a “U-value.” Because windows are not insulators by design, they cannot be measured in R-values. However, windows obviously have insulating properties, so there needs to be a measurement that allows comparison of styles and window packages.

There is a relationship between R-values and U-values. Whereas the higher the R-value, the greater its insulating ability, the lower a U-value, the better that product’s insulating efficiency. To find a U-value, divide the number ‘1′ by the R-value. For example, an R-value of “4” is equal to a U-value of .25.

When planning an addition, building a new home, or replacing windows, be sure to consider placement as to southern exposure and room size as well as the energy efficiency of the windows. This will ensure your satisfaction and comfort when the job is done.
