How do Air Source Heat Pumps work?

Air Source Heat Pumps, or ASHPs, work on the principle of transferring heat energy from the outside air to the interior of a building during colder seasons and extracting heat from the indoor air to release it outside during warmer seasons. ASHPs consist of an outdoor unit and an indoor unit, connected by refrigerant lines.

The outdoor unit contains a fan, a compressor, and a heat exchanger. The fan draws in air from the surroundings, and the heat exchanger extracts heat from this air, even in temperatures as low as -15 to -20 degrees Celsius (5 to -4 degrees Fahrenheit). The compressor increases the temperature of the extracted heat, making it suitable for space heating or hot water.

The indoor unit typically includes a heat exchanger and a fan or blower to distribute the heated air throughout the building. In some cases, ASHPs can also be equipped with a reversing valve, allowing them to operate in reverse to provide cooling during hot weather, similar to an air conditioner.

Professional Installation

Our highly trained and professional installation engineers will design, install and commission your system up with the minimum of fuss and at a time to suit you.

Boiler Upgrade Scheme (BUS)

The Boiler Upgrade Scheme (BUS) supports the decarbonisation of heat in buildings. It provides upfront capital grants to support the installation of heat pumps in homes and non-domestic buildings in England and Wales.

Get £5,000 from the Boiler Upgrade Scheme

£5,000 government grants will be given to households as part of the Boiler Upgrade Scheme to promote clean heat from low carbon technologies such as heat pumps. to decarbonise the nation through the Heat and Buildings Strategy announced by the UK Government with a budget of £450 million run over 3 years starting April 2022.

Air Source Heat Pumps FAQs*

What is an air source heat pump?

An air source heat pump (ASHP) is a heating and cooling system that extracts heat from the air outside a building and transfers it indoors for heating purposes. It works on the principle of using refrigerant to absorb heat from the outside air, then compressing and transferring it indoors.

How does an air source heat pump work?

An air source heat pump consists of an outdoor unit (containing a compressor, fan, and heat exchanger) and an indoor unit (which distributes the heated or cooled air). The outdoor unit absorbs heat from the outdoor air, and the refrigerant inside the system carries the heat indoors. Inside, the heat is released into the building, and the cooled refrigerant returns to the outdoor unit to repeat the process.

Are air source heat pumps energy-efficient?

Yes, air source heat pumps are considered energy-efficient heating and cooling systems. They can generate up to three units of heat for every unit of electricity consumed. However, their efficiency can vary depending on factors such as outdoor temperature, insulation levels, and the specific model and installation.

Can air source heat pumps be used for both heating and cooling?

Yes, air source heat pumps can provide both heating and cooling. They can extract heat from the outdoor air for heating during colder months and reverse the process to remove heat from indoors and provide cooling during warmer months.

What are the benefits of using an air source heat pump?

Air source heat pumps offer several benefits, including energy efficiency, reduced carbon emissions, lower operating costs compared to traditional heating systems, versatility for both heating and cooling, and the potential to qualify for government incentives or rebates in some regions.

Are air source heat pumps suitable for all climates?

Air source heat pumps can be effective in a wide range of climates. While they work best in moderate climates with average winter temperatures above freezing, advancements in technology have made them more suitable for colder climates as well. However, in extremely cold regions, a backup heating system may be necessary.

How does the efficiency of air source heat pumps change with temperature?

The efficiency of air source heat pumps decreases as the outdoor temperature drops. However, modern heat pumps are designed to provide effective heating even in colder climates. The heating capacity of a heat pump is typically specified by the manufacturer for different outdoor temperature ranges.

What is the lifespan of an air source heat pump?

The average lifespan of an air source heat pump is typically around 15 to 20 years. Proper maintenance and regular servicing can help ensure optimal performance and prolong the lifespan of the unit.

Are air source heat pumps noisy?

Air source heat pumps produce some noise, but modern models are designed to minimize the sound. The noise levels are generally comparable to other common household appliances, such as a refrigerator or an air conditioner.

Are there any financial incentives available for installing air source heat pumps?

Depending on your location, there may be financial incentives available for installing air source heat pumps. These incentives can include tax credits, rebates, or grants offered by governments or utility companies to promote energy efficiency. It is advisable to check with local authorities or energy agencies to explore available incentives in your area.

*Please note that specific details and requirements may vary depending on your location and the particular air source heat pump system.
