How air source heat pumps work
Air-source heat pumps use renewable heat from the outside air to warm your home and provide hot water through an efficient heating cycle.
-
Capture heat: The outdoor unit absorbs heat from the air into a refrigerant.
-
Increase temperature: The refrigerant is compressed, raising its temperature.
-
Heat your home: The warmed refrigerant transfers heat to your radiators or underfloor heating.
-
Provide hot water: Any remaining heat is stored in a hot water cylinder for daily use.
This efficient process repeats continuously, delivering reliable heating and hot water throughout the year.
Why switch to an air source heat pump?
Are you looking for a more sustainable way to heat your home? If so, you have come to the right place. A Mellor Plumbing & Heating Services Limited are experts in renewable energy solutions, specialising in installing and maintaining air source heat pumps in Bacup and throughout Lancashire. Traditional heating systems can be unpredictable, expensive to run, and produce many harmful emissions. Air-source heat pumps offer an efficient and affordable alternative.
Our team can manage the whole installation process, so you can simply enjoy your new heat pump system. There are many reasons to make the switch to an air-source heat pump, including:
-
Extended lifespan: With a traditional boiler, you will get a 12-year lifespan; if you’re lucky with an ASHP, you will get nearly double that. They often last 20 years or more before they need to be replaced.
-
Low maintenance: Once your ASHP is installed, it requires very little maintenance. Often all that’s needed is a quick inspection now and again. Gone are the times of costly regular maintenance and frequent breakdowns that you experience with traditional gas or LPG heating systems.
-
Reduced heating bills: As heat pump systems don’t burn any fossil fuels to heat your home, you can say bye to costly gas heating bills, saving you money on your home’s heating bills.
-
Return on investment (ROI): When you install an ASHP, you add value to your property, making it a sound investment and an attractive prospect to future potential buyers or renters. Government grants: There are many government schemes available to help with the installation of your ASHP, with grants of up to £7500. Our team can even help you with the application process.
-
Eco-friendly: Heat pump systems don’t burn any fossil fuels when supplying your home with heat. This results in a 75% reduction in CO₂ emissions.
At A Mellor Plumbing & Heating Services Limited, we are passionate about climate change, and by choosing a greener energy solution, you are showing your dedication to delivering a better environment for generations to come. Our engineers are fully trained and have many years of experience installing and maintaining air source heat pumps, so you know that your heat pump system will be installed to the highest possible industry standard.
