What is the HSPF rating ?

How is the HSPF calculated on a heat pump?

If you’re looking for an air conditioner or a heat pump, you’ve probably heard of the abbreviation HSPF. The term HSPF stands for Heating Seasonal Performance Factor. In French, you will find the abbreviation FRSC which means Factor of Seasonal Efficiency in Heating.

The HSPF is actually a ratio or rating of energy efficiency that each device is evaluated according to their heating performance. In other words, the higher the HSPF, the less energy the appliance will consume during the heating season. Now, it is important to understand that HSPF is only a measurement for “heating” and is not applicable for cooling data from air conditioners. The HSPF energy efficiency is the ratio between the heating power in (BTU/h) divided by the gross energy consumption of the appliance (Watt/h or kWh). This is the average for a heating season and is calculated using a constant indoor temperature of approximately 20°C and an outdoor temperature of 8°C.

All heat pumps have an energy efficiency rating for the heating season and it must be displayed on the unit’s Energy Guide (yellow) sticker.

Is HSPF so important? I confirm that yes!

At first glance, the term HSPF doesn’t mean much, but if you compare the different rates, there can be a huge difference in energy consumption between heaters over a 20-year lifespan. . However, it is extremely important to weigh the investment costs of purchasing the device against the profitability of the device in the long term. Obviously there is no point in buying an appliance with an HSPF of 12+ if you intend to move in 2-3 years, because it is the next owner of your house who will benefit from the move. energy savings of your heat pump.

If you plan to stay in your home for several years, buying a heat pump with a high energy efficiency rate will have several benefits.

First, a heat pump with an HSPF greater than 10+ will consume significantly less energy compared to one that has an HSPF of 8.

Second, appliances with a higher HSPF are usually considered “high end” appliances so your appliance will also have a higher SEER and that will save you money for the cooling season (what is SEER?). It is important to consider the HSPF of heat pumps if you live in Quebec, because we must not forget that we have about 3-4 months of summer and 8-9 months of cold weather. HSPF will save you more on energy consumption compared to SEER.

Third, appliances with a high HSPF are usually built by industry-recognized manufacturers who have many years of experience in designing heating appliances (heat pumps). To obtain a high HSPF, manufacturers must use the best parts and components in order to obtain high performance yields. So this assures you that your device is built with quality materials.

Finally, buying a heat pump is not an easy task, particularly because of their acquisition costs. It is therefore important that you are well advised according to your needs, your current situation and your budget.
