Compare heat pumps vs gas central heating on efficiency, running costs, comfort, and environmental impact. [View Heat Pumps](/heat-pumps)[0333 577 7010](tel:03335777010) ## Efficiency Comparison Heat pumps are significantly more efficient than traditional central heating systems. A modern gas boiler operates at 85-95% efficiency, meaning up to 15% of energy is wasted. An air source heat pump achieves 300-400% efficiency (COP of 3-4), producing 3-4 kW of heat for every 1 kW of electricity used. This efficiency advantage translates directly into lower energy bills. While gas may be cheaper per unit than electricity, the heat pump's superior efficiency means it uses far less energy overall. A well-designed heat pump system typically costs 20-40% less to run than a gas boiler. ## Running Costs Annual heating costs for a typical 3-bedroom semi-detached home: Gas boiler: £800-£1,200. Oil boiler: £1,200-£1,800. LPG boiler: £1,400-£2,000. Air source heat pump: £500-£800. Ground source heat pump: £400-£700. These figures demonstrate that despite electricity costing more per unit than gas, the heat pump's efficiency more than compensates. For homes currently on oil, LPG, or electric heating, the savings are even more dramatic. ## Environmental Impact A gas boiler produces around 2-3 tonnes of CO₂ per year. An air source heat pump using grid electricity produces about 1-1.5 tonnes, and this figure continues to fall as the UK electricity grid decarbonises. By 2030, heat pumps could be virtually zero-carbon. If you pair your heat pump with solar panels or a green electricity tariff, you can achieve zero-carbon heating today. This is impossible with any fossil fuel boiler, making heat pumps the clear winner for environmentally conscious homeowners. ## Comfort and Convenience Heat pumps provide a more consistent, even temperature throughout your home compared to the on-off cycling of a gas boiler. Instead of short bursts of intense heat followed by cooling periods, a heat pump maintains a steady warmth that many homeowners find more comfortable. Modern heat pump systems offer smart controls, smartphone apps, and weather compensation that automatically adjust heating output based on outside temperatures. They also provide cooling in summer (with air-to-air systems), something no gas boiler can do. ## Related Guides & Resources [ ### Heat Pump Systems Samsung & Vaillant air source heat pump installation. ](/heat-pumps)[ ### BUS Grant (£7,500) How to claim your Boiler Upgrade Scheme grant. ](/boiler-upgrade-scheme-bus)[ ### How Heat Pumps Work Understand the technology behind air source heat pumps. ](/ashp/how-do-heat-pumps-work)[ ### Radiators for Heat Pumps Sizing guide, upgrade costs, and radiator compatibility. ](/ashp/radiators-for-heat-pumps)[ ### Heat Pump Costs Full pricing guide for heat pump installation. ](/ashp/how-much-does-a-heat-pump-cost)[ ### Are Heat Pumps Worth It?
