HSPF2 (Heating Seasonal Performance Factor 2) is the updated rating system used to measure the heating efficiency of a heat pump over an entire season. A higher HSPF2 rating indicates that the system uses less electricity to provide a specific amount of heat, making it a crucial metric for winter comfort. Our Alpic Eco series is engineered to deliver high HSPF2 ratings even in freezing northern climates. This rating is part of the 2023 DOE standards that also introduced the SEER2 metric for cooling. When shopping for a Multi-Zone system, comparing HSPF2 values helps you estimate your potential winter energy savings. Systems with high HSPF2 are often eligible for federal tax credits and localized utility rebates. We prioritize these high-efficiency Components to ensure our customers get the best possible return on their investment. Understanding HSPF2 allows you to choose a system that is as effective at heating as it is at cooling.
