Air Source Heat Pumps

---

Air source heat pumps are a highly energy-efficient heating option, significantly outperforming traditional boilers by delivering three to four times more heat energy than the electricity they consume. In comparison, modern condensing boilers typically achieve around 90 to 95 percent efficiency. Although the upfront costs for heat pumps are generally higher, ranging from £7,000 to £14,000 before any government grants for heat pumps, new boiler installations usually fall between £1,500 and £4,000. Over time, heat pumps can lead to lower running costs, especially in well-insulated homes, and they generate much lower carbon emissions since they operate on electricity, which can be sourced from renewable energy. Additionally, heat pumps tend to have a longer lifespan—typically 20 to 25 years—compared to a boiler’s average lifespan of 10 to 15 years. While maintenance for heat pumps is less frequent, it may require specialist support, whereas boilers benefit from more readily available servicing. Noise can also be a consideration: heat pumps have an outdoor unit that may produce some sound, while boilers are usually quieter indoors. Finally, heat pumps are currently eligible for various government grants for heat pumps, such as the Boiler Upgrade Scheme, which can significantly reduce upfront costs by several thousand pounds, whereas traditional boilers are less likely to qualify for similar incentives, making heat pumps a more sustainable heating solution.
