Are you feeling bamboozled by air-source heat pumps and heat pump technology in general? You’re not alone. Many UK homeowners shy away from these efficient and versatile systems because they feel a little daunted by how they work.
We’ve put together a handy guide explaining how air-source heat pumps work, how they can save you money, and why they might be the best decision you make for your comfort and home. We’ll also tell you how you can get a heat pump for your home with an energy-saving heat pump grant.
How Do Air Source Heat Pumps Work?
Air-source heat pumps are an efficient and eco-friendly way to heat and also cool your home, making them an attractive option for UK homeowners. These systems work by extracting heat from the outside air, even in cold temperatures, and transferring it into your home.
During the winter, the pump absorbs heat from the air and amplifies it using a refrigeration cycle. Then, it distributes the warmth through your home via radiators or underfloor heating. In the summer, the process reverses, and the pump* (*depending on model) acts like an air conditioner, removing heat from your home to keep it cool.
One key benefit is the significant reduction in energy bills and carbon footprint, especially if an air source heat pump is used in conjunction with a renewable energy system, such as solar PV panels or a wind turbine.
Moreover, with the UK’s commitment to reducing carbon emissions, installing an air-source heat pump can also qualify you for government incentives, making it a smart investment for the future.
How Much Space Does a Heat Pump Take Up?
The space required for an air-source heat pump depends on the type and model, but generally, they are quite compact. Here’s a breakdown of the typical space requirements:
Outdoor Unit: The outdoor unit, which is usually about the size of a large suitcase, needs to be placed in an open, well-ventilated area. It requires about 1-2 meters of clear space around it for adequate airflow and maintenance access. Ideally, it should be installed on a solid base like a concrete slab or in some cases can be mounted on an exterior wall.
Indoor Unit: The indoor unit is often wall-mounted and comparable in size to a standard boiler. It can be installed in various locations, such as a utility room, garage, or cupboard, and requires less space than traditional heating systems. The exact dimensions vary, but typically it will need around 60-70 cm width, 50-60 cm depth, and 150-170 cm height.
How Efficient Are Air Source Heat Pumps?
They are highly efficient, converting each unit of electricity into 3-4 units of heat, making them more energy-efficient than traditional heating systems. By switching from a non-condensing LPG or Oil Boiler to a heat pump, savings of over £1000 per year can realistically be expected, especially if used in conjunction with renewable energy.
Are Air Source Heat Pumps Suitable For Any Home?
Air-source heat pumps are suitable for most homes, especially those with good insulation and underfloor heating. They work best in homes that are well-insulated to maximise efficiency and cost savings.
What Are The Primary Benefits Of Using Air Source Heat Pumps?
Benefits include lower energy bills, reduced carbon footprint, and eligibility for government incentives such as the Renewable Heat Incentive (RHI). They also provide a reliable and sustainable heating solution, even in colder temperatures.
How much do air source heat pumps cost to install and operate?
Installation costs typically range from £10,000 to £20,000, depending on the size and complexity of the system. Due to their high efficiency, operating costs are lower than traditional heating systems, potentially saving you money on energy bills.

How Efficient Are Air-Source Heat Pumps Compared To Other Heating Systems?
Air source heat pumps can achieve efficiencies of 300-400%, meaning they produce three to four times more heat energy than the electrical energy they consume. This makes them significantly more efficient than traditional boilers.
Can Air Source Heat Pumps Function Effectively During Winter?
Yes, air source heat pumps are designed to operate efficiently even in temperatures as low as -15°C. They can reliably provide heating throughout the winter months.
What Kind Of Maintenance Is Required For Air Source Heat Pumps?
Maintenance is minimal, typically involving annual checks by a professional. Tasks include cleaning filters, checking refrigerant levels, and ensuring the system operates efficiently.
Do Air Source Heat Pumps Also Provide Hot Water?
Yes, air-source heat pumps can provide both space heating and hot water for your home, making them a versatile heating solution.
Are Air Source Heat Pumps Noisy?
Modern units are designed to be quiet, typically producing noise levels comparable to a refrigerator. As the ASHP unit is located outside the property, it is very unlikely that you will hear it from inside your home.
Can They Work With Existing Radiators?
Yes, but larger radiators or underfloor heating systems are recommended for maximum efficiency.
How Long Do Air-Source Heat Pumps Last?
With proper maintenance, they can last 20 to 30 years.
How Can I Get a Heat Pump Grant?
You might not realise you could qualify for a heat pump grant. Anyone living in England, Scotland, or Wales can apply for government grants to reduce the cost of installing an air source heat pump. Grants of up to £7,500 are available.
Fill in our grant checker today to see if you qualify for a heat pump grant. Heat pumps are one of the best ways to heat and cool the home and could reduce your energy costs and carbon footprint considerably. Stop relying on an old and inefficient heating system when a heat pump can improve your comfort throughout the home and throughout the year.
