Energy efficiency measures installed by Key Renewables

Heat Pumps

Heat pumps are becoming a popular, energy-efficient, low-carbon heating solution suitable for almost all homes. They can significantly reduce your energy bills and carbon footprint, especially when replacing older heating systems. As demand for sustainable heating grows, more homeowners are choosing heat pumps to future-proof their homes.

Regular maintenance is essential to keep your heat pump performing at its best, ensuring long-term efficiency and reliability. At Key Renewables, our expert engineers provide dedicated aftercare as part of our comprehensive heat pump service. With annual inspections and proactive commercial heat pump maintenance, we help extend the lifespan of your heat pump, optimise performance, and protect your investment for years to come.

Air source heat pump servicing involves a professional check-up and maintenance of your system, typically on an annual basis, to ensure optimal operation and longevity. This includes cleaning filters, checking refrigerant levels, inspecting electrical components, and verifying system function. Regular servicing helps maintain efficiency, prevents issues, and keeps your manufacturer's warranty valid.
