Can an air-source heat pump be wall-mounted?
Pro arguments
- Saves space
If you have limited outdoor space, wall mounting your air-source heat pump can free up ground area for other uses. Leaving you more room around your house.
- Improves air flow
Positioning the air-source heat pump unit higher on a wall can enhance air flow around the heat pump as it can avoid other obstructions.
- Protects from debris
Elevated heat pump units are less likely to be affected by debris, such as leaves or snow, that could accumulate around ground-mounted air-source heat pump units. Allowing less maintenance.
- Fits houses and flats
Wall mounting a heat pump often enables you to install it for flats which otherwise couldn't be heated with a heat pump. This is particularly useful in built-up, urban locations where every square metre counts.
Technical considerations
Requirements for wall-mounted installation of a heat pump.
- Structural supportThe wall chosen for the installation must be strong enough to support the weight of the heat pump. This often requires a professional assessment to ensure that the wall can handle the load without compromising structural integrity.
- Noise and vibrationsIt may be that the location is close to the boundary lines for your property and could be near a neighbour where the sound levels may be a nuisance. Wall-mounted units can transmit vibrations and noise. Installing anti-vibration mounts and ensuring proper insulation can mitigate these issues, providing a quiet operation.
- Access for annual servicingAn engineer must have safe and suitable access to the heat pump for annual servicing. It may void your manufacturers guarantee if an annual service is not completed.
- Clearance and air flowYou will need to allow enough clearance around the air-source heat pump to comply with the manufacturers installation guidance. You must ensure the heat pump is located in an open area to allow air to circulate freely.
- Local building regulations and guidanceYour must consider local building regulations that may restrict installation, such as planning permission if the heat pump unit is visible from public spaces.
- Installation heightThe height at which you mount the heat pump can affect its performance. It’s crucial to follow the manufacturer’s guidelines to ensure optimal efficiency and functionality.
Wall-mounted vs. floor-mounted: which is right for you?
Deciding whether to wall mount your air-source heat pump depends on various factors that are bespoke to your home and lifestyle.
Do you have limited outdoor space? If your garden is small, wall mounting your heat pump can free up valuable ground space.
Is your home structurally suitable? You must ensure that your walls can support the weight and installation of an air-source heat pump.
Wall mounting an air-source heat pump can be a practical and efficient solution for many homeowners. It can often offer space-saving solutions and improve airflow to your heat pump, whilst protecting it from debris. However, it is crucial to consider structural support, local building regulations and proper installation to ensure optimal performance.
Your installer will be able to provide the guidance on location, sizing and any additional measures your property will need to have an air-source heat pump installed.
Benefits of floor mounting
Your best alternative: our floor-mounted heat pumps.
- Easy maintenance
Floor-mounted units are generally easier to access for maintenance and repairs compared to wall-mounted units. This can simplify routine checks and servicing, potentially extending the lifespan of the system.
- Increased stability
Floor mounting can be advantageous in situations where wall structures are not strong enough to support the weight of an air-source heat pump, or where wall mounting could compromise the building's structural integrity.
