Air Source Heat Pump Pros and Cons


Advantages of Air Source Heat Pumps

To help you understand why air source heat pumps are becoming a popular choice for those looking to upgrade their heating systems, we’ve outlined the key advantages below:

1. Eligible for government grants

The Boiler Upgrade Scheme (BUS) is a key incentive to explore. This government initiative provides a grant of £7,500 to help offset the upfront cost of installing an air source heat pump in homes across England and Wales. By working with an accredited installer, you can access this funding without the hassle of applying yourself, as the installer handles the process on your behalf.

With the scheme running until 2028, it's an excellent opportunity to make your home more energy-efficient while reducing the financial burden of switching to renewable heating.

2. Eco-friendly and sustainable

By choosing an air source heat pump, you're making a positive impact on the environment. These systems use renewable energy from the air around your home, reducing your reliance on fossil fuels and lowering your carbon footprint. As you become more conscious of your environmental impact, you'll appreciate how this technology aligns with your sustainability goals and contributes to a greener future.

3. Compatible with solar panels

Air source heat pumps can work seamlessly with solar panels. This combination allows you to use both air and sun which further reduces your energy bills and environmental impact. By integrating these two renewable technologies, you're setting yourself up for a more sustainable and cost-effective home energy system.

4. Minimal maintenance required

Unlike traditional heating systems that require regular servicing and part replacements, air source heat pumps are designed for longevity and reliability. With just occasional check-ups and filter cleanings, you can enjoy consistent performance and peace of mind, knowing that your heating system won't demand frequent attention or costly repairs.

Air source heat pumps are gaining popularity among installers. This growing trend means you'll have access to a wider pool of experienced professionals who can properly install and maintain your system. As more installers become familiar with this technology, you can expect improved service quality, competitive pricing and easier access to support when you need it.


Disadvantages of Air Source Heat Pumps

While these systems offer many advantages, they're not without their drawbacks. Below, you'll find a breakdown of the key factors that might give you pause before committing:

1. High Initial Investment

It’s important to be aware of the higher upfront costs compared to traditional heating systems. While the long-term savings and efficiency benefits can outweigh this initial expense, the substantial investment can be a hurdle for many. It's important to factor this into your budget and explore available grants or financing options to make the transition more manageable.

2. Unsuitable for Certain Properties

Air source heat pumps aren't ideal for every property type and you may find that your home isn't well-suited for this technology. Factors like limited outdoor space, poor insulation or architectural constraints can make installation challenging or less effective. Before committing to an air source heat pump, it's crucial to assess whether your property can support its requirements and deliver optimal performance. A qualified heat pump installer, such as Glow Green, can help you determine if your property is suitable.

3. Often Requires Home Modifications

Switching to an air source heat pump often involves making changes to your home. You may need to upgrade insulation, install larger radiators or adjust your heating system to accommodate the lower temperature output of the pump. While these modifications can enhance efficiency, they add extra costs and effort to the installation process that you should plan for in advance.

4. Generates Some Operational Noise

Unlike traditional boilers, air source heat pumps can produce noise during operation due to their external unit. While this noise is generally minimal, it might be noticeable if the unit is installed close to living areas or neighboring properties. If you're sensitive to sound or have limited outdoor space, you'll want to consider how this could impact your comfort or surroundings.

5. May Need Planning Permission

Depending on where you live, installing an air source heat pump might require planning permission. This is especially true if your home is in a listed building, conservation area or has specific restrictions on external modifications. Navigating planning regulations can add time and complexity to the installation process so it's worth checking local requirements before moving forward.


What is an Air Source Heat Pump and How Do They Work?

Simply put, an air source heat pump is a device that captures heat from the air outside your home and uses it to warm your living space. The air source heat pump works by transferring heat from the outside air to a refrigerant, which then circulates through your home's heating system, providing warmth. This process is efficient and environmentally friendly which makes it an attractive alternative to traditional heating systems.


Is an Air Source Heat Pump Suitable for Your Home?

When considering if an air source heat pump is worth it, there are several factors to weigh. Firstly, if your property has good insulation, you're already on the right track. Having adequate outdoor space for the external unit is also crucial. Also, if you're open to making necessary home upgrades - like installing larger radiators or underfloor heating - to optimise the system's performance, an air source heat pump could be a great fit for you.

Your environmental values play a role too - if you're committed to reducing your carbon footprint or have already invested in solar panels, an air source heat pump aligns well with your eco-friendly goals. However, if the cost and the need for significant home upgrades are concerns for you, an air source heat pump might not be the best fit for you and your home.
