What Are Air Source Heat Pumps?

Air source heat pumps (ASHPs) are an innovative way of heating your home by extracting heat from the air outside—even when temperatures are as low as -15 °C—and using them to warm your home and provide hot water.

Unlike traditional heating systems, which burn fuel to generate heat, ASHPs move heat from one place to another, making them an extremely energy-efficient option. The process works much like a refrigerator, but in reverse, it captures heat from the outside air and transfers it into your home’s heating system.

Benefits of Air Source Heat Pumps

Energy Efficiency and Reduced Bills

One of the major advantages of air-source heat pumps is their impressive energy efficiency. They can provide up to five times more energy than they consume in electricity, with a Coefficient of Performance (COP) of up to 5:1, meaning that for every unit of electricity used, the pump can deliver up to five units of heat(source: Worcester Bosch). This efficiency could translate directly into savings on your heating bills, especially compared to older, less efficient systems like oil or gas boilers or direct electric heating.

Environmental Benefits

Air source heat pumps are a renewable energy technology, making them a great choice for reducing your carbon footprint. By using natural heat from the air, ASHPs reduce reliance on fossil fuels, significantly cutting greenhouse gas emissions(source: Worcester Bosch). As the world moves towards more sustainable energy solutions, heat pumps are a key component in transitioning to a low-carbon future. For homeowners, this means contributing to environmental preservation while enjoying the comforts of an efficient heating system.

Government Incentives

Installing an air source heat pump could also make you eligible for financial incentives from the UK government. Schemes such as the Boiler Upgrade Scheme (BUS) provide grants to help cover the cost of installation​(source Worcester Bosch). This initiative encourages homeowners to adopt renewable energy systems by providing up to £7,500 for an air source heat pump. Combined with the long-term savings on energy bills, these incentives make ASHPs a smart financial investment for the future. MJM Plumbing (Lincoln) Ltd are registered installers for the Boiler Upgrade Scheme.

Low Maintenance and Longevity

Air source heat pumps require relatively little maintenance compared to traditional heating systems. With periodic checks and servicing, an ASHP can last up to 20 years, providing a reliable and cost-effective solution for long-term heating needs(source: Worcester Bosch). MJM Plumbing (Lincoln) Ltd, offers comprehensive servicing plans to ensure that your heat pump continues to operate at peak efficiency, reducing the likelihood of unexpected breakdowns and extending the life of your system.

Flexible Installation

MJM Plumbing (Lincoln) Ltd installs air source heat pumps in various properties, from new builds to older homes undergoing renovation. Unlike ground source heat pumps, which require significant land for installation, ASHPs only need external space for the outdoor unit.

This makes them suitable for urban, suburban, and rural properties alike (source: Worcester Bosch). Furthermore, the compact design of modern air source heat pumps means they take up minimal space and can often be installed without requiring planning permission.
