The Homeowner’s Ultimate Guide to Air Source Heat Pumps

With the increasing need for energy-efficient and eco-friendly heating solutions, air source heat pumps (ASHPs) have emerged as an attractive option for many homeowners. Offering a cleaner, greener alternative to traditional fossil fuel heating systems, ASHPs provide significant energy savings and a sustainable way to heat your home. In this comprehensive guide, we will explore how air source heat pumps work and their associated benefits while discussing the installation process of The Electric Heating Company‘s Iconic Air heat pump.

To develop a thorough understanding of air source heat pumps, it is essential to comprehend their basic principles, which involve extracting heat from the ambient air outdoors, amplifying it, and then transferring it indoors to heat your living space. This process relies on the science of thermodynamics, utilising a refrigerant to facilitate the absorption and release of heat energy. By contrast, traditional heating systems burn fuel to generate heat, contributing to carbon emissions and environmental harm.

There are several advantages to choosing an ASHP as your home’s primary heating source, including reduced carbon emissions, lower energy bills, minimal maintenance requirements, and compatibility with underfloor heating systems. Moreover, ASHPs can contribute to reduced reliance on fossil fuels and are often eligible for renewable heating incentives, providing financial benefits for homeowners.

How Air Source Heat Pumps Work

1. Heat Absorption

The process of air source heat pumps begins with the outdoor unit extracting heat from the ambient air, even on colder days. This outdoor unit houses a heat exchanger and a fan. As the fan blows air over the heat exchanger, it transfers the captured heat to a refrigerant, which is well suited for absorbing and transferring heat energy.

2. Heat Amplification

The refrigerant, now infused with heat energy, is then compressed using a compressor to increase its temperature further. This heat is subsequently transferred to the indoor heating system via a second heat exchanger.

3. Heat Distribution

The indoor unit of the ASHP connects to your home’s heating distribution system (such as underfloor heating or radiators), efficiently transferring the heat from the heat pump to heat your living spaces. When used with underfloor heating systems, ASHPs can operate at a lower temperature, thereby achieving higher levels of energy efficiency.

4. Repeating the Cycle

Finally, the refrigerant’s pressure is reduced, causing it to cool down. The refrigerant then returns to the outdoor unit, and the cycle starts once more. This continuous process ensures a constant supply of heat to your home while maintaining energy efficiency.

5. Iconic Air’s Special Feature 

The Iconic Air, Air Source Heat Pump comes with an extra feature of a modulating element inside the indoor unit. The modulating boost heating element collaborates with the heat pump to maintain the desired temperature, particularly during low outdoor temperatures. It also serves as a backup heating source when the outdoor unit is undergoing maintenance, ensuring continuous heating for the property.

Advantages of Air Source Heat Pumps

1. Reduced Carbon Emissions

Air source heat pumps contribute to a significantly lower carbon footprint compared to traditional fossil fuel-based heating systems. This reduction is due to their renewable energy generation capabilities and higher efficiency levels.

2. Lower Energy Bills

With a greater emphasis on energy efficiency, ASHPs can contribute to reduced energy bills, especially for homeowners replacing older and less efficient heating systems. This energy efficiency allows for a greater return on investment over the heat pump’s lifespan.

3. Minimal Maintenance

Air source heat pumps boast minimal maintenance requirements compared to traditional heating options. With a life expectancy of up to 20 years, regular servicing and occasional component replacements are the only maintenance tasks necessary to ensure optimal performance.

4. Compatibility with Underfloor Heating Systems

ASHPs are well suited for use with underfloor heating systems, which require lower water temperatures than conventional radiators. The lower operating temperatures in underfloor heating systems allow ASHPs to work more efficiently, contributing to further energy savings.

Installing an Iconic Air Heat Pump

1. Selecting the Right System Size

The first step in installing an Iconic Air heat pump is determining the correct size for your specific property. Consulting with a qualified heating engineer will help ensure the heat pump meets your unique heating requirements while maximising efficiency.

2. Property Preparation

It is crucial to prepare your property for the installation of an ASHP. This preparation includes ensuring suitable outdoor space for the heat pump’s outdoor unit and easy access for maintenance. Additionally, it is essential to insulate your home thoroughly to minimise heat loss and increase the overall efficiency of the heat pump.

3. Hiring Qualified Professionals

Enlisting the help of experienced professionals is integral in guaranteeing a successful ASHP installation. These professionals should possess all the necessary certifications and expertise to ensure a smooth, efficient, and cost-effective installation process.

4. Complying with Building Regulations

It is vital to comply with all relevant building regulations and health and safety standards when installing an ASHP. Your installer should be familiar with these requirements and able to assist you in meeting them, ensuring a legally compliant and safe installation process.


Air source heat pumps, such as The Electric Heating Company‘s Iconic Air, provide homeowners with a more sustainable and energy-efficient heating solution. By understanding how air source heat pumps work, recognising their advantages and familiarising yourself with the key aspects of installation, you will be prepared to make an educated decision about a suitable heating system for your home.
