An energy efficient heat pump can cool your home as effectively as a similarly sized air conditioner, but a heat pump is much more flexible. When the outside weather turns cold, a heat pump can reverse cycle to provide heat as needed. This flexibility gives homeowners a new level of control over their HVAC system. Heat pumps are also a great way to help reduce seasonal utility costs. Of course, not all heat pumps are the same. Fortunately, when it comes to measuring individual heating efficiency, all you have to remember is HSPF.
HSPF: Heating Seasonal Performance Factor
As you may have already eruditely inferred from the subtitle, HSPF stands for Heating Seasonal Performance Factor. Which sounds really complicated, but don't worry. Basically, HSPF just measures the energy efficiency of a given heating unit over an operating season. The higher the rating, the more energy efficient a given unit can perform. So, roughly speaking, the higher the rating, the less money you are going to spend when you use your heat pump to generate heat. And who doesn't like saving money?
