#hspf

Heat pumps are rated in terms of HSPF (Heating Seasonal Performance Factor). In general, the higher the HSPF rating, the less electricity the unit will use to do its job. In 1992, the federal government established the minimum heating efficiency standard for new heat pumps at 6.8 HSPF. (Most heat pumps manufactured before 1992 had HSPF ratings below 5.) The minimum HSPF standard changed again in 2006 to an HSPF of 7.7. Today, an HSPF of 8.2 or higher is considered “high-efficiency”; the maximum available is 9.35.

For many homeowners, electric heating is the simplest way to warm spaces where a central heating system might not reach.(More…)

Because heating and air conditioning technology improve over time, a unit designed with newer, more energy-efficient equipment makes sense, especially if your system is 7 or more years old.(More…)
