Switching from a Gas Boiler to a Heat Pump: A UK Resident's Guide
Eco-Friendly Advantages of Switching from a Gas Boiler to a Heat Pump
When thinking about replacing a gas boiler with a heat pump, it’s essential to consider the environmental effects. In the UK, heat pumps generate approximately 1.6 tonnes of CO2 per year, largely because the electricity grid still relies on fossil fuels.
The environmental impact of heat pumps is closely connected to the energy mix powering the grid. As the UK continues to expand its use of renewable energy, heat pumps will help drive down CO2 emissions even further. In fact, over the last two decades, the CO2 output of the UK grid has halved, making heat pumps a cleaner alternative to traditional systems.
By comparison, gas boilers release about 2.2 tonnes of CO2 per year, while oil boilers are even more harmful at around 5.3 tonnes. Additionally, gas boilers contribute to air pollution, producing eight times the nitrogen dioxide of the UK’s gas power plants, a pollutant associated with various health risks.
Comparing Heat Pump and Gas Boiler Efficiency
The cost to install a heat pump can vary based on your home’s size, the type of heat pump, and the installation complexity.
Air source heat pumps usually cost between £8,000 and £15,000. On the other hand, ground source heat pumps are more costly, ranging from £17,000 to £25,000. This higher price is due to the additional garden work needed for installing slinkies or boreholes.
Factors that affect the installation cost include whether your home is new or existing (new builds are generally cheaper), the size of your home, any necessary prep work like setting up a new electricity supply, and if your radiators need upgrading for better efficiency.
Other Reasons to Switch to an Air Source Heat Pump
- Lower Energy Bills
Switching to an air source heat pump could cut your energy bills by as much as 40%*, depending on your current system. With an efficiency of about 400%, air source heat pumps outperform gas boilers, which average around 90% efficiency.
- Reduced Maintenance Costs
Air source heat pumps are built to last and require less frequent maintenance than boilers. Wimbledon Heat Pumps also provides performance and product maintenance, ensuring peace of mind with every installation.
- Heating and Cooling in One System
Air source heat pumps can both heat your home in winter and cool it in summer. By transferring heat rather than generating it, they efficiently keep your home comfortable year-round when combined with fan coils for cooling.
- Improved Energy Efficiency
More energy-efficient than gas boilers, air source heat pumps don’t burn fossil fuels, helping you lower your carbon footprint and contribute to a more sustainable future.
MCS Heat Pump Installation
When installing a heat pump, it's essential to select a reputable installer who is accredited by the Microgeneration Certification Scheme (MCS). An MCS-approved installer, such as Wimbledon Heat Pumps, will ensure your heat pump is fitted correctly and meets all required safety and quality standards.
Opting for an MCS-accredited installer also opens the door to the Boiler Upgrade Scheme, a government grant that can reduce the cost of your heat pump by £5,000 to £6,000. If you choose Wimbledon Heat Pumps, we will manage the grant application process for you.
The Boiler Upgrade Scheme supports the transition from fossil fuel boilers to low-carbon heating solutions like heat pumps. To see if your project qualifies for the grant, review the eligibility criteria here or contact our team of experts for assistance.
Switching from a gas boiler to an air source heat pump can help UK homeowners lower their energy bills, reduce carbon emissions, and cut maintenance costs. Though the initial cost may seem high, government grants can significantly reduce it. Heat pumps provide both heating and cooling, making them an efficient choice year-round. Expect better energy efficiency and long-term savings, especially with an accredited installer to ensure a smooth and reliable installation.
