Do Heat Pumps Work in Cold Climates?
Heat pumps are known for their ability to draw warmth from outside air, even in freezing conditions. This article explores how a cold climate heat pump operates effectively as temperatures drop, making heat pumps in winter a viable option for keeping homes warm without excessive energy use.
Your heat pump will extract energy from the outside air in order to heat your pump’s refrigerant, which will then start evaporating immediately , even at minus temperatures. This means it’s extremely unlikely that your heat pump will freeze over. The result? Cosy warmth and lower energy costs during the chilliest months.
What’s the Coldest Temperature a Heat Pump can Work at?
The coldest temperature a heat pump can function at depends on two factors, which type you have and how well insulated your home is. Here at D-mec we supply and install quality air-source heat pumps from the top brands. Our air source pumps can operate effectively in an impressive temperature range of -25℃ to 32℃.
During the winter, the UK climate sees average temperatures of just below 0℃ which isn’t remotely close to -32℃, meaning even when your heat pumps in cold weather, it’ll keep you warm with ease.
How to Boost Heat Pump Efficiency in Winter
Heat pumps perform reliably in winter, though due to the extreme colder temperatures they may suffer slight efficiency loss. Here are some life-saving tips to make your heat pump in cold weather more efficient:
- Regular maintenance: It is important to get your heat pump serviced by one of our HVAC engineers, at least once a year. This will ensure that the air filter is clear and replaced when necessary.
- Ensure your heat pump is clear of leaves and debris: By regularly checking your pump is clear, you will eliminate the risk of your pump being blocked or damaged. This is a simple step you can take yourself to ensure your heat pump works efficiently.
- Keep the thermostat on one setting: It may be tempting to play around with the temperature but keeping it at one setting will keep the heat pump running as efficiently as possible. This will also benefit the environment and your energy bill.
Is a Heat Pump Cover Worth it?
During the cold months in the UK, many heat pump owners consider buying a cover to protect their heat pump in winter. While this seems like a smart choice, there are some potential negatives to covering a pump.
Heat pump covers are intended to protect against extreme snow and winter elements but as the UK isn’t a snowy climate, it’s not necessary. Covering your heat pump can jeopardise efficiency, restrict airflow and in some cases void manufacturers warranty. By restricting the airflow, it forces the heat pump to work harder to reach desired temperature, which can lead to higher energy bills.
Other potential negatives of a heat pump cover include reduced lifespan due to wear and tear, and risk of pests. By covering the heat pump it creates a shelter likely to attract pests, this increases the risk of damaged wires and maintenance issues.
Unless you live in a consistently snowy climate with extreme winter conditions, we wouldn’t recommend installing a heat pump cover. Regular maintenance and ensuring the pump is clear of debris will do the job just fine.
