Air source heat pump energy consumption – save on heating costs

In recent years, winter electricity prices have skyrocketed to record highs, causing heating costs to put a serious dent in homeowners' wallets. An air-to-air heat pump can significantly reduce these expenses. In this article, we'll explain how much electricity an air source heat pump consumes and what determines its energy efficiency. You'll learn how the right unit and smart usage can lower heating costs in Finnish conditions, and how to evaluate electricity consumption and savings.

How much electricity does an air source heat pump consume? Choose a model suited for the Nordic climate

When used correctly, an air source heat pump can cut home heating costs and carbon emissions by up to half. The device collects thermal energy and transfers it via refrigerant from the outside air indoors when heating, and from indoors to the outside when cooling. Electricity consumption remains low, as power is only needed to run the compressor and fan motors. Generating heat with electric heaters, for example, is significantly more expensive. Even when used for cooling, energy consumption is minimal if used wisely.

You get the most benefit with the right device and proper use. The colder the air, the more energy the device uses for heating, which is why an air source heat pump must be suitable for cold Nordic conditions. During heating, condensation drips from the outdoor unit, which can cause it to freeze. However, devices designed for the Nordic climate defrost the outdoor unit automatically and energy-efficiently in freezing temperatures.

Air source heat pumps still use the old energy labels, with separate ratings for cooling and heating. A single device might have an A+++ rating for cooling but an A+ rating for heating. Annual heating consumption is also affected by where in Europe the pump is used. Naturally, heating is required more and for longer in Finland than in Central or Southern Europe.
