Kelvin’s hybrid electrification solution combines traditional radiator heating systems with electric heat pumps, specifically designed for radiator-heated buildings. By integrating our Cozy radiator enclosure system, window/sleeve heat pumps, and thermal batteries, we offer a cost-effective and simple pathway to building decarbonization. This approach leverages high-efficiency electric heating during milder conditions and traditional radiator heating during extreme weather events or when required by other factors. Kelvin’s hybrid electrification is a scalable and innovative solution that reduces energy consumption, lowers carbon emissions, and promotes a cleaner energy future.
