Should I get a heat pump or a boiler?
Written by:
Key takeaways:
- Heat pumps are considerably more efficient than gas boilers, making them a more economic and environmentally sound choice
- Gas boilers are familiar with lower upfront costs, but are more expensive and far less efficient to run
- A heat pump is a great long term investment for your home, your wallet, and the environment
Deciding between a heat pump and a boiler is a crucial step in ensuring your home stays warm while maintaining efficiency. Each system offers distinct advantages and considerations, making it essential to evaluate your specific needs and priorities.
How heat pumps work
Heat pumps are renewable energy systems that extract heat from natural sources like air or the ground, providing an efficient and eco-friendly alternative to traditional heating. Unlike boilers, heat pumps transfer heat rather than generate it, allowing them to achieve remarkable efficiency levels of 300-400%. For every unit of electricity consumed, heat pumps can produce three to four units of heat, significantly reducing energy consumption. Among the most popular options, air source heat pumps stand out for their adaptability and ease of installation. Although slightly less efficient than ground source models, they perform effectively in various climates when correctly sized and installed in well-insulated homes.
The benefits of heat pumps
The benefits of heat pumps are extensive. They are highly energy-efficient, outperforming gas boilers that typically operate at about 85-90% efficiency. Heat pumps also offer long-term cost savings. While the initial investment is higher, they can reduce annual energy expenses by hundreds, if not thousands, of pounds, especially when paired with renewable energy sources like solar panels. An air source heat pump can save homeowners about 25% on their energy bills annually. Their efficiency also means that homeowners can significantly cut their carbon emissions, typically by 75%. Additionally, government incentives, such as the Boiler Upgrade Scheme, provide grants of up to £7,500 to help offset installation costs, making heat pumps an increasingly viable option for many households.
The drawbacks of heat pumps
Despite their advantages, heat pumps do come with some challenges. The upfront costs can be higher than those of traditional heating systems, with installation expenses starting from £5,450 after BUS, depending on the type of system. Aira also offers financing solutions through our partners. Heat pump systems also require space for an outdoor unit, which needs adequate airflow to function effectively. Heat pumps deliver steady, lower-temperature heat, so may not function as efficiently in homes with poor insulation unless additional upgrades are made.
How boilers work
Boilers are a more traditional solution, burning fuel to heat water that circulates through radiators or underfloor pipes. Gas boilers are the most common type in the UK, known for their lower upfront costs and quicker, more intense heating capabilities. Installation is straightforward and typically completed within a day, making boilers an accessible choice for many homeowners.
The drawbacks of boilers
While boilers offer convenience, they are far less efficient, with most operating at about 85-90% efficiency. Boilers rely on fossil fuels, leading to higher carbon emissions. A modern A-rated gas boiler emits approximately 215 grams of CO2 per kilowatt-hour, contributing significantly to climate change. Regular maintenance is also required, with boiler cover and annual servicing adding to the long-term cost of ownership.
Which heating system is right for you?
Ultimately, choosing between a heat pump and a boiler depends on your home, budget, and environmental goals. Heat pumps are ideal for those seeking a sustainable, long-term solution with lower operating costs and greater return on investment, while boilers remain a cost-effective and convenient option for quick, high-temperature heating. Carefully weighing the initial investment, long-term savings, and environmental impact will help you determine the best heating system for your home.
