Designed to give a more realistic measure of performance over an entire year, seasonal ratings take into account:
- Performance in different climate zones
- Performance at both full and partial capacity
- Energy consumption in auxiliary and stand-by modes
- Varying load requirements owing to temperature fluctuations
What SCOP and SEER give you is an indication of energy consumption vs. heating or cooling output respectively. And since air source heat pumps can heat and cool, you’ll find both SCOP and SEER ratings provided by the manufacturer.
What is the Efficiency of an Air Source Heat Pump?
When it comes to seasonal efficiency, products vary, but generally speaking the higher the rating the better. This means your heat pump requires less energy to operate, lowering your carbon footprint and generating cost savings.
A key thing to remember though is that SCOP and SEER indicate maximum efficiency, and this will not be achieved in all circumstances.
To ensure the greatest energy savings, an air source heat pump should be correctly matched to the demands of the building in which it is installed. In domestic properties this is fairly straightforward, but in a business setting it’s more complex - you’ll need to account for how the space is used and typically occupancy, as well as considering a flexible design, future proofed for any possible changes in premises use.
