Busting the Myths: Common Misconceptions about Air Source Heating Debunked

Air source heating systems are rapidly gaining popularity in the UK, touted for their energy efficiency, eco-friendliness, and cost-saving potential. However, amidst the buzz, several misconceptions cloud the understanding of this technology. Here at Cahill Renewables, we aim to clarify air source heating by debunking these common myths and highlighting the true benefits they offer.

Myth 1: Air source heating doesn’t work in cold climates.

Fact: Modern air source heat pumps (ASHPs) operate efficiently even in colder regions like the UK. They can extract heat from the air even at temperatures as low as -25°C, thanks to advanced technology and refrigerant fluids. While their performance might decrease slightly in extreme cold, they still outperform traditional electric heating systems and provide ample warmth. Over 40% of Nordic homes use air-source heat pumps to heat their homes, it’s far colder in Denmark than the UK!

Myth 2: Air source heating is expensive to install and maintain.

Fact: While the initial cost of installing an ASHP is higher than a traditional boiler, government incentives and long-term energy savings often make the cost of installation of an ASHP comparable. Additionally, ASHPs require minimal maintenance, with annual inspections being recommended. Their lifespan also tends to be longer than gas boilers, further reducing overall costs.

Myth 3: Air source heating requires major modifications to your home.

Fact: The installation process for air source heating is relatively straightforward and doesn’t necessitate significant modifications. Our team at Cahill Renewables takes a “hands-off” approach, minimizing disruption to your home environment. In most cases, the outdoor unit simply needs a space with good airflow, while the new hot water cylinder connects to your existing heating system with minimal pipework changes.

Myth 4: Air source heating systems are noisy and unsightly.

Fact: Modern ASHPs operate at noise levels comparable to a refrigerator, making them unobtrusive in most residential settings. The outdoor unit is similar in size to a typical air conditioning unit and can be discreetly placed in your garden. There used to be planning requirements stipulating heat pumps couldn’t be within 1M of the boundary of your land, however thanks to advancements in ASHP technology making them whisper quiet, this planning requirement has now been scrapped!

Myth 5: Air source heating isn’t as reliable as traditional heating systems.

Fact: ASHPs are built with robust components and designed for reliable operation. They come with warranties and require minimal maintenance. Additionally, their reliance on electricity rather than gas fuel eliminates concerns about fuel shortages or leaks.

Benefits of Air Source Heating Systems:

• Reduced energy bills: ASHPs extract heat from the air efficiently, consuming less energy than traditional electric heaters. This translates to significant cost savings on your energy bills.
• Lower carbon footprint: By utilizing renewable energy from the air, ASHPs minimize greenhouse gas emissions compared to fossil fuel-powered heating systems.
• Government incentives: The UK government offers grants and schemes to encourage the installation of ASHPs, reducing the initial investment cost.
• Increased value: Homes with ASHPs are increasingly attractive to potential buyers, potentially fetching a higher price due to their energy efficiency and sustainability features and bump up in EPC rating

How Air Source Heating Works:

ASHPs operate similarly to refrigerators but in reverse. The outdoor unit extracts heat from the air using a refrigerant fluid. This heat is then compressed and transferred indoors, where it warms your home through radiators, underfloor heating, or hot water systems.

Energy Efficiency of Air Source Heating:

ASHPs achieve exceptional energy efficiency, typically boasting a Coefficient of Performance (COP) of 3-4. This means that for every unit of electricity they consume, they can generate 3-4 units of heat energy. Traditional electric heaters, in contrast, have a COP of <1, translating to higher running costs.

Comparing Air Source Heating to Other Heating Systems:

• Gas boilers: While initially cheaper, gas boilers have higher running costs and contribute to greenhouse gas emissions.
• Electric heaters: Offer lower upfront costs but are significantly less energy efficient, leading to higher electricity bills.
• Ground source heat pumps: Only ~20% more efficient but involve more complex and super expensive installation due to the need for underground ground loops or boreholes.

Cost Savings with Air Source Heating:

While the initial installation cost of an ASHP might be fractionally higher (thanks to Government grants) when compared to a traditional boiler, the long-term benefits quickly outweigh it. With lower energy bills, government incentives, and minimal maintenance costs, ASHPs can offer significant savings over their lifespan.

Government Incentives for Air Source Heating Installation:

The UK government offers several schemes to encourage the adoption of ASHPs. These include the Boiler Upgrade Scheme, which provides grants of£7,500 towards the installation of air source heat pumps for eligible households. Applications are made by MCS-certified installers on behalf of property owners (As an MCS-approved installer, we will do this all for you!).

Choosing the Right Air Source Heating System:

Selecting the right ASHP for your home requires careful consideration of several factors:

• Property size and insulation: The size and energy efficiency of your home will determine the required heating capacity of the ASHP.
• Heating system type: Consider compatibility with your existing radiators, underfloor heating, or hot water system.
• Budget: Weigh the initial investment against long-term energy savings and available government grants.

Investing in Your Future with Air Source Heating:

By choosing air-source heating, you’re not just investing in your comfort and saving money on energy bills; you’re making a responsible choice for the environment. As the world transitions towards renewable energy sources, ASHPs represent a future-proof and sustainable solution for your home heating needs.
