Heating is one of the biggest contributors to carbon emissions in UK homes. This blog explores how switching from traditional heating methods to air source heat pumps (ASHPs) can dramatically reduce your environmental impact. We’ll also cover how these systems work, their long-term benefits, and what you need to consider before installation.
Reducing Environmental Impact with Air Source Heat Pumps
The Problem with Traditional Heating
Conventional heating systems, particularly gas and oil boilers, are major contributors to the UK's carbon emissions—accounting for roughly 37% of total output. Gas boilers burn fossil fuels on-site, releasing carbon dioxide directly into the atmosphere and worsening both climate change and air quality.
By contrast, ASHPs offer a cleaner alternative. Replacing a gas boiler with an ASHP can cut household carbon emissions by up to 23%, and switching from oil can yield a reduction of up to 68%. This makes heat pumps one of the most effective solutions for sustainable home heating.
How Air Source Heat Pumps Work
ASHPs function by transferring heat from the outside air into your home—even in freezing temperatures as low as -15°C. Here’s how they work:
- A fan draws in outside air, passing it over refrigerant coils.
- The refrigerant absorbs heat and is compressed, raising its temperature.
- This heat is transferred to your home’s hot water or heating system via a heat exchanger.
- The cycle repeats, continuously extracting heat from the air.
Many systems are reversible, meaning they can also act as air conditioners in summer by removing heat from your home.
Benefits of ASHPs
Lower Carbon Emissions
ASHPs produce no direct emissions during operation. Their carbon footprint is linked to the electricity source used to power them, and with the UK grid becoming increasingly green, this footprint continues to shrink.
High Energy Efficiency
Heat pumps are highly efficient, producing around three units of heat for every unit of electricity consumed. In contrast, the best gas boilers reach just 90% efficiency. This difference leads to noticeable energy savings over time.
Compatibility with Renewable Energy
ASHPs work exceptionally well with home solar panels or green energy tariffs. When powered by renewable sources, they offer nearly carbon-neutral heating and hot water, aligning perfectly with the UK’s low-carbon goals.
Long-Term Sustainability
The UK government aims to phase out gas boilers in favour of low-carbon alternatives by 2035. With grant support like the £5,000 Boiler Upgrade Scheme, now is a smart time to consider switching to a heat pump system and future-proof your home.
Key Considerations for Installation
Installing an air source heat pump is a long-term investment that requires thoughtful planning. Key factors to assess include:
Property Suitability
- Insulation: Proper insulation improves ASHP performance.
- Space: Outdoor and indoor units require sufficient clearance.
- Heating system: Best results come from pairing with underfloor heating or large radiators.
Regulatory and Financial Aspects
- Planning permission: Generally not required, but check with your local authority.
- Cost: Higher initial cost compared to boilers, but lower running costs and government grants help offset this.
System Selection and Installation
- Correct sizing: Ensure your system is matched to your home’s heating demands.
- Efficiency ratings: Choose units with high COP and SPF values.
- Noise level: Select quieter models, especially for built-up areas.
- Smart controls: Allow better temperature control and scheduling.
- Accredited installer: Always choose an MCS-certified installer for quality and grant eligibility.
By making these considerations, homeowners in Barnsley, Rotherham, and Sheffield can make an informed decision that benefits both their property and the environment.
