Is Your Home Suitable for an Air Source Heat Pump?

Are you searching for the perfect heating solution to keep your home cosy and energy efficient all year round? Look no further than air source heat pumps! These remarkable devices have gained significant traction in recent years, thanks to their ability to extract heat from the surrounding air and use it to warm your home.

 However, a common misconception around air source heat pumps is that not every property is suited for an air source heat pump. In this guide, we'll explore how heat pumps are a sustainable and efficient way to heat a variety of homes- old or new. 

Understanding Air Source Heat Pumps

Air source heat pumps capture the latent heat energy present in the outdoor air and transfer it indoors to heat your living spaces. This process is remarkably efficient, with air source heat pumps capable of producing up to three times more energy than they consume.

Unlike traditional gas boilers, which generate heat through combustion, air source heat pumps leverage the refrigeration cycle to move heat from one place to another. This means they can provide both heating and cooling, making them a versatile choice for year-round comfort.

Is my home suitable for an air source heat pump?

While there are several factors affecting the suitability of your home, for most, an air source heat pump will be suitable and provide many advantages to your home. Factors such as insulation, outdoor space, correct design and installation and whether it is compatible with your current heating system all need to be considered to make sure you get the most out of your investment. 

1. Proper Insulation

Effective insulation is the foundation for any energy-efficient heating system, and air source heat pumps are no exception. Your home's walls, loft, and windows should be well-insulated to minimise heat loss and ensure the heat generated by the pump is retained within the living spaces.

Homes with poor insulation will struggle to maintain a consistent temperature, as the heat produced by the air source heat pump will quickly dissipate. This can lead to higher energy consumption and increased running costs, diminishing the benefits of this eco-friendly heating solution.

2. Underfloor Heating or Large Radiators

Air source heat pumps operate at lower temperatures compared to traditional boilers, typically around 35-40°C. To effectively distribute this heat throughout your home, you'll need a heating system that can efficiently utilise these lower temperatures.

Underfloor heating or oversized radiators are ideal, as they provide a larger surface area for heat transfer. Standard radiators may not be able to effectively circulate the heat generated by an air source heat pump, leading to uneven temperatures.

3. Sufficient Outdoor Space

Air source heat pumps require an outdoor unit to be installed, typically placed on an external wall or in a garden, this unit needs adequate space around it to ensure unobstructed airflow. However, if your property does lack the necessary outdoor space, or if the available area is too cramped, some heat pump models can be mounted on a wall. It is always necessary to discuss with an installer the best placement of a heat pump to ensure minimal disruption to air flow. 

4. Interior Space for the Indoor Unit

In addition to the outdoor unit, air source heat pumps also require an indoor unit, which houses the heat exchanger and controls. This indoor component needs to be situated in a suitable location within your home, with enough space for proper airflow and heat distribution.

Depending on the specific model, the indoor unit may take up a significant amount of space, so it's important to carefully consider where it can be positioned without compromising the functionality or aesthetics of your living spaces.

5. Compatibility with Existing Heating System

If your home already has a central heating system in place, it's crucial to ensure that an air source heat pump can be seamlessly integrated. 

In some cases, upgrading or modifying the existing system may be necessary to ensure optimal performance and efficiency when paired with an air source heat pump. This could involve installing larger radiators or making adjustments to the overall heating distribution network.

6. Heating Demand of your Home

You need to consider the size of your property, the number of occupants and your demand for hot water. The higher your demand, the larger the size of heat pump output you will require. Contact a trusted heat pump installer to work out the size of the heat pump which will best meet your heating demands. 

7. Age of your Home

One common misconception is that air source heat pumps are not suitable for older homes- this is not true. While older homes typically require more work to improve insulation levels, there is typically no reason why an older home can’t benefit from a heat pump. It’s always worth contacting a local heat pump installer to ensure your home is eligible and if not, what can be done to improve its suitability

8. Noise levels

Some homeowners worry that the outdoor unit of an air source heat pump may be excessively noisy, however, manufacturers have made significant strides in reducing the noise levels of these units, with many modern models operating at a decibel level comparable to a standard household appliance. If possible, aim to place the heat pump away from neighbours’ windows and gardens to ensure minimal disruption.

When selecting an air source heat pump, be sure to consider the noise specifications and choose a model that aligns with your preferences and the surrounding environment.


Determining whether your home is suitable for an air source heat pump requires careful consideration of various factors, including insulation, heating system compatibility, and available outdoor and indoor space. By understanding these key considerations, you can make an informed decision on the most appropriate heating solution for your property.

If your home ticks the boxes for an air source heat pump, you can look forward to enjoying the benefits of a highly efficient, eco-friendly heating system that can help you save money on your energy bills while reducing your carbon footprint.
