How much energy does an ASHP use in freezing vs. mild weather?

The electricity consumption of a heat pump can vary significantly depending on the weather conditions. In freezing temperatures, heat pumps need to work harder to extract heat from the cold air, leading to higher electricity usage. Conversely, in milder weather, they operate more efficiently and use less electricity. This variability is a key consideration for anyone looking to understand the energy efficiency and operating costs of heat pumps in different climates and seasons.

Discover the electricity usage of our 18kW air source heat pump in varying temperatures. We’ve closely monitored its consumption during colder days when temperatures fall below 0°C, as well as during milder conditions, with temperatures above 7°C. This data offers insights into the efficiency and cost-effectiveness of using a heat pump across different weather scenarios, providing an understanding of its performance in real-world conditions.
