Today, heat pumps have an HSPF rating of about 8, transferring 2.34 times heat against electricity consumed. The HSPF ratings can be converted to the seasonally averaged COP by changing BTUs and electricity consumed to joules – a standard energy unit.Īvg COP = Heat transferred / electricity consumed If you’re wondering where this number came from, read on: To identify the COP value of a heat pump, you have to multiply the HSPF rating of the heat pump by 0.293. You can measure HSPF or heat pump efficiency through the Coefficient of performance or COP.ĬOP measures the amount of heat transferred against the electricity consumed.

But how much electricity did we consume? Well, the average US price per kilowatt-hours is $0.13, and the required power was 20,000kWh. Now, convert kWh into watt-hours, and since 1kWh = 1000Wh, we get: HSPF = Heating effect (BTUs) / Electricity consumed (kWh) Therefore, we can calculate the HSPF rating of heat pumps using this formula: Meanwhile, the heat pump powered by 20,000 kWh generates almost 160,000,000 BTUs of heat. ft of space during long winters, we drain approximately 20,000 kWh. The average heating we experience and our heating capacity needs in BTU.įor instance, to heat around 1500 sq.Electricity spent on heating and its power usage in kilowatt-hours kWh.HSPF is the metric unit of energy efficiency for equipment such as heat pumps. This model can offer impressive energy savings compared to most Energy-Star-approved heat pumps.
It’s still considered the highest energy-efficient unit on the market. In short, it’s a five-stage heat pump that provides excellent performance! 13.0 HSPFĬarrier Infinity has another heat pump known as the Infinity 20 with an excellent 13.0 HSPF rating of heating efficiency. It can operate anywhere from 25 to 100%, which means that these units only require the bare minimum energy. Heat pumps with 11.0 HSPF ratings are super-efficient, i.e., Carriers’ Infinity 18VS.
Heat pumps with 8.5 HSPF ratings meet the minimal standards for better energy efficiency in the United States and come with Energy Star certification, ensuring less consumption and higher savings! 11.0 HSPF In many instances, 8.2 HSPF rated heat pumps are much more efficient than most of the older heat pumps you’re planning to replace.
