In the pursuit of net-zero emissions, heat pumps emerge as a pivotal technology. Among the various types, air source heat pumps are prevalent in the UK. Leveraging renewable heat extracted from the outdoor air, these pumps offer an eco-friendly alternative for heating and hot water. Recognising their importance, the UK saw the installation of 55,000 heat pumps in 2021, with an ambitious target of reaching 600,000 installations per year by 2028. Operating a heat pump costs around £1,540 annually, but delivers a significant environmental impact, saving nearly 2 tonnes of CO₂ each year compared to an average gas boiler. Despite a marginal increase in operational costs, the investment aligns with both personal energy efficiency goals and the broader commitment to the planet's ecosystem. There are government grants available for the Air Source Heat Pump Installation Initiative, where homes can receive up to £7,500 in England and Wales. It is worth noting that Heat pump systems can only be installed by MCS accredited professionals.
