How does an air source heat pump work in cold weather?
As winter draws closer, you might be wondering whether your air source heat pump (ASHP) will work during the colder weather.
Rest assured, air source heat pump systems are designed to provide warmth even if the air temperature outside drops, ensuring your home stays cosy throughout the season.
Let's look a bit closer at how an air source heat pump delivers winter warmth, while at the same time, providing an efficient, cost-effective heating solution.
Benefits of air source heat pumps in UK winters
Air source heat pumps have numerous advantages during UK winters. These systems provide efficient heating even when the air temperature is low, leading to reduced energy consumption and lower bills. They provide a greener alternative to traditional heating systems, utilising renewable energy from the air to minimise carbon emissions.
With government incentives and grants available, installing an ASHP is becoming more accessible and cost-effective. These financial supports promote a shift towards sustainable heating solutions, making them an attractive option for eco-conscious homeowners in the UK like you.
Operating an air source heat pump in winter
Now let’s look at how air source heat pumps work. An ASHP captures heat from the outside air and transfers it indoors. You can think of this process as being like the one that keeps your fridge cool, but in reverse. But you might be thinking, “What if it’s freezing outside? Will the system still provide warmth?” The short answer is yes! In fact, air source heat pumps can work well in temperatures as low as –25 degrees in some cases, although it’s unlikely that we will experience such temperatures here in the UK.
As the system absorbs warmth from the cold air, the refrigerant inside the pump evaporates and turns into a gas. This is then compressed, raising its temperature significantly, and the generated heat is then transferred to your home, keeping you comfortable, no matter what the weather outside.
