What is an air source heat pump?

An air source heat pump (ASHP) is a renewable technology that extracts heat from the air to provide indoor heating or water heating. 

It works by absorbing heat from the outside air, even in cold weather, and then raising the temperature to warm your space and water.

Air source heat pumps offer a more environmentally friendly option compared to traditional heating systems dependent on fossil fuels. They can notably cut down carbon emissions and reliance on non-renewable energy.

By using heat from the air, which is an essentially limitless resource, ASHPs contribute to lowering the carbon footprint of heating systems, playing a part in addressing climate change.

The UK government promotes air source heat pumps (ASHPs) to support low-carbon and renewable energy technologies. People get help to use ASHPs in homes and businesses. 

This helps make energy use better, reduces pollution, and supports the country’s goal to have zero carbon emissions.

Using air source heat pumps in the UK fits with wider environmental goals and plans, like those in the Clean Growth Strategy and the aim to reach zero carbon emissions by 2050. ASHPs help reduce pollution in heating by lowering carbon emissions, which are a major contributor to overall emissions.

Benefits of Air Source heat Pump

Reduced carbon emissions and environmental impact

ASHPs rely on renewable energy, significantly reducing greenhouse gas emissions compared to traditional fossil fuel-based heating systems.

High efficiency

Modern ASHPs can achieve a coefficient of performance (COP) of up to 5 meaning they can generate 5 units of heat for every 1 unit of electricity consumed.

Lower running costs

ASHPs can significantly reduce your heating bills compared to traditional systems, especially in well-insulated homes.

Modern Control

ASHPs are useful for heating both your home and water, making them a complete solution for all your heating needs.

Air Source Heat Pump Installation Guide in 2024

Air Source Heat Pumps (ASHPs) are gaining popularity for their efficiency and sustainability in heating homes and businesses. This guide walks you through the key stages of ASHP installation, helping you make informed decisions about adopting this technology.

We will consider factors like heating capacity, energy efficiency (COP), climate compatibility, brand reputation, and budget when choosing your ASHP. We will prioritize a system that suits your specific climate and offers long-term energy savings.

Site Assessment & BUS Grant

Before installation, a qualified installer evaluates your heating needs, considering your home’s size, insulation, and existing system. They identify suitable locations for outdoor and indoor units based on space, sunlight, noise, and accessibility.

The optimal ASHP size is determined for efficient performance by means of a full room by room heat loss calculation. Your installer will then apply for the £7500 BUS grant on your behalf.

Equipment Selection & Installation of the outdoor unit

The outdoor unit, housing the evaporator coil, compressor and condenser coil is crucial. The process includes preparing the location, securely mounting the unit, connecting pipework and hydraulic components, and electrical wiring by a qualified electrician.

Indoor Installation

After selecting an appropriate location for any indoor components such as your hot water cylinder and system controls a qualified technician will connect up the system. After making connections, a qualified technician tests and adjusts the system for optimal performance. This ensures everything is working efficiently and safely.

Finishing Up & Completion of the BUS Grant

Final steps involve cleaning the work area, demonstrating system operation, and providing important documentation like user manuals and warranty information. Your system will then be commissioned by an MCS registered engineer, all paperwork will be completed and the £7500 BUS grant voucher will then be redeemed.

How Air Source Heat Pumps Work: Unlocking Sustainable Comfort

Extracting Heat from the Air

An Air Source Heat Pump (ASHP) operates by extracting heat from the ambient air outside, even in colder temperatures. It utilises a refrigerant that evaporates at low temperatures, absorbing heat from the outdoor air.

Compression and Temperature Increase

The absorbed heat is then compressed, causing the refrigerant to become hot. This process significantly increases the temperature of the refrigerant, turning it into a high-temperature gas.

Heat Exchange with Your Home

The high-temperature gas is then passed through a heat exchanger inside your home. This allows the heat to transfer to the heating system, whether it’s underfloor heating, radiators, or a forced-air system.

Distribution of Heat

The now-cooled refrigerant returns to the outdoor unit, and the process repeats. The heat extracted from the air is efficiently distributed throughout your home, providing a consistent and comfortable indoor temperature.

Efficient Control Technology

Advanced control technology regulates the temperature and output, ensuring optimal efficiency and comfort. Some systems even allow for cooling in warmer months, providing a versatile solution year-round.

Energy Efficiency and Environmental Benefits

Air Source Heat Pumps are renowned for their energy efficiency. They require minimal electricity to operate, making them a cost-effective and environmentally friendly heating solution. By harnessing heat from the air, they contribute to reducing carbon emissions and promoting sustainability.

Understanding the fundamental process of how Air Source Heat Pumps work showcases their versatility, efficiency, and commitment to sustainable heating solutions. SL Energy is your trusted partner in bringing this innovative technology to your home.
