Long term energy saving tips for a more efficient home
In the UK, almost one fifth of carbon emissions are generated by our homes. This includes everything from heating, lighting and appliances. This article will look at a few ways that you can help reduce energy bills for homeowners while helping the planet along the way.
One of the main sources of energy loss is through the roof. Residential energy efficiency measures extend beyond insulation to loft spaces. The absence of loft insulation, compared to an optimal depth of 270mm, could potentially yield substantial benefits. Homeowners adopting the recommended insulation depth may save approximately £250 annually, alongside a notable reduction of 620kg of CO₂ emissions each year.
Air source heat pumps
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.
Solar panels
For those considering renewable energy sources, solar panels stand out as a popular choice. An average domestic solar panel system, rated at 3.5kWp, requires an initial installation cost of around £7,000. Beyond potential cost savings on energy bills, this eco-friendly solution can contribute to a significant reduction in carbon emissions, up to 0.83 tonnes per year (depending on geographical factors). Solar panels also offer the advantage of not only cutting energy bills but potentially generating income by supplying excess energy back to the grid.
Battery storage
Enhancing the effectiveness of solar energy systems, battery storage serves as an optional yet valuable addition. This feature allows homeowners to store surplus energy during periods of sunlight abundance for use on days or months when sunlight may be scarce. By maximising energy usage and minimising reliance on external sources, battery storage complements the overall sustainability of a solar-powered home.
