What low-carbon heating system does the Government suggest homeowners replace old gas boilers with?

The Government recommends that homeowners replace old gas boilers with heat pumps as a low-carbon heating system because heat pumps are designed to be more energy efficient and significantly reduce carbon emissions compared to traditional fossil fuel heating systems. Heat pumps operate by extracting heat from the environment (air, ground, or water) and transferring it into the home for heating purposes. This technology can harness renewable heat sources, making it a more sustainable choice.

In addition, heat pumps have the capacity to work in reverse during warmer months, providing cooling, which makes them versatile for year-round home climate control. This aligns with governmental efforts to promote cleaner energy solutions in response to climate change and energy security concerns.

Other options, while they can contribute to reducing carbon emissions in various capacities, don’t specifically carry the same level of endorsement as a direct replacement for boilers within this context. For instance, solar panels are primarily used for generating electricity rather than directly heating water or spaces, electric heaters may still rely on grid electricity that could be generated by fossil fuels, and geothermal systems, while effective, often require significant initial investment and are less commonly applicable for all homeowners.
