Heat pump running costs: turning rumours into savings.
Energy consumption of a heat pump
What makes a heat pump economically superior?
Heat pumps are not just a modern heating solution; they redefine energy efficiency. Yet, many wonder about their energy consumption and the costs involved. Let's explore the expected energy costs and what influences them. But first, the essentials:
The efficiency of a heat pump indicates how much usable heat it delivers in relation to the energy supplied. Compared to other heating systems they achieve rates between 300% and 500%. Impressively, 75% of the energy a heat pump uses is sourced from the environment - air, ground, or water - leaving only 25% powered by electricity. This means for every 1 kWh of electricity, a heat pump produces four times the heat energy. It's a smart, cost-effective way to warm your home.
Factors influencing energy consumption
Defining factors of a heat pump's elctricity demand.
- Flow temperature
The larger your heating surfaces are, the lower is the flow temperature they require. And the lower flow temperature requirements are, the less energy your heat pump consumes to meet them.
- Insulation
Enhanced insulation across a building, including windows, walls, roof, and basement, boosts energy efficiency and minimises energy consumption.
- Your needs
A household's heating energy consumption is influenced by the size of the house, number of residents, your individual heating and hot water requirements and more.
- Supporting systems
A heat pump can be supplemented with another product to increase efficiency, such as a photovoltaic system or a domestic hot water storage. These heat pump systems can lead to lower operating costs.
Energy sources for heat pumps
The essential role of energy sources in electricity consumption.
- Air-source
- Ground-source

Air-source heat pumps
The air source heat pump experiences the most significant temperature changes from its main energy source, the heat in the surrounding air. When outside temperatures drop, more electricity is needed to reach the desired heating level, leading to fluctuating electricity usage. However, the air-source heat pump stands out for its simple and affordable installation process.
Understanding heat pump efficiency
One part in, four parts out - that's what we call efficient.
The energy consumption of a heat pump is closely tied to its Coefficient of Performance (COP) and Seasonal Coefficient of Performance (SCOP). COP measures efficiency by comparing energy input to heating output under fixed conditions. For instance, a heat pump uses just 1 kWh of electricity to produce 4 kWh of heat.
The SCOP, on the other hand, adjusts these conditions to various climatic regions, providing a wider efficiency outlook.
Our air-source heat pump , boasts an impressive energy efficiency rating of A+++ with a COP of 3.5. This means it delivers 3.5 kWh of heat for every 1 kWh of electricity used, showcasing significant savings potential.
Go even more efficient with photovoltaics.
Combine heat pumps with photovoltaics for a truly eco-friendly and cost-efficient heating solution. By installing a photovoltaic system on your roof, you can generate your own electricity. This not only liberates you from electricity providers but also protects the environment and slashes your operating costs.
Typically, 10 to 12 solar panels can comfortably meet the needs of a four-person household. With a total area of around 20 square metres, these easily installable panels can fit even on smaller roofs. Even when facing south, they still generate significant energy, ensuring efficiency and sustainability.
