Common Issues with Air Source Heat Pumps and How to Prevent Them

In our short blog we give you some tips in how to get the most from this fantastic renewable energy option for your home or business.

Poor Installation

Issue:

Incorrect installation, such as improper sizing or poor placement, can lead to inefficiency and higher energy costs. An undersized heat pump may struggle to meet heating demands, while an oversized system may short-cycle, reducing efficiency and lifespan.

Prevention:

• Work with certified professionals like Eljay Energy, who have expertise in correctly sizing and positioning ASHPs to suit your property’s needs.
• Ensure thorough heat loss calculations are performed before installation.
• Place the outdoor unit in an area with adequate airflow and minimal obstruction.

Cold Climate Performance

Issue:

Although modern ASHPs are designed to operate efficiently in low temperatures, extreme cold can slightly reduce their performance. Frost build-up on the outdoor unit can also impact efficiency.

Prevention:

• Invest in a high-quality ASHP with a defrost mode that prevents excessive frost accumulation.
• Ensure proper installation to maximise heat extraction even in cold conditions.
• Consider pairing your ASHP with an additional heat source for extremely cold days if required.

‍Noise Levels

Issue:

Some heat pumps can generate noise, particularly if the installation is suboptimal. Vibration or incorrect mounting may amplify operational sounds, which can be a nuisance.

Prevention:

• Choose a high-quality, low-noise model.
• Ensure professional installation, with the outdoor unit placed away from windows and living areas.
• Use vibration-reducing mounts and soundproof barriers where necessary.

Insufficient Insulation

Issue:

A poorly insulated property forces the ASHP to work harder, reducing its efficiency and increasing energy consumption.

Prevention:

• Ensure walls, floors, lofts, and windows are well insulated before installing an ASHP.
• Upgrade to double or triple-glazed windows if possible.
• Conduct an energy audit to identify and address heat loss areas.

Maintenance Needs

Issue:

Like all heating systems, ASHPs require regular servicing to maintain efficiency and prevent issues such as reduced airflow, refrigerant leaks, or blocked filters.

Prevention:

• Schedule regular professional servicing, ideally once a year, with a trusted provider like Eljay Energy.
• Clean or replace air filters as recommended by the manufacturer.
• Check for obstructions around the outdoor unit and clear any debris.
• Monitor performance and address any unusual noises or efficiency drops promptly.

Overview

While Air Source Heat Pumps are a fantastic sustainable heating solution, they need proper installation and maintenance to function at their best. By working with experienced professionals like Eljay Energy, ensuring proper insulation, and scheduling routine maintenance, you can maximise your ASHP’s efficiency, longevity, and cost-effectiveness.
