Whitepaper

This white paper presents a detailed technical, economic, and environmental assessment of the Haydale high performance, graphene-based heating system, JustHeat.

This technology utilises plasma-functionalised graphene inks printed onto flexible panels to deliver uniform resistive heating directly beneath floor coverings. This paper focuses on the advantages of the JustHeat system, specifically highlighting its features and capabilities compared to other heating technologies and methods.

Unlike traditional heating methods such as gas boilers, air source heat pumps, and electric or wet underfloor heating systems, the JustHeat system demonstrates a uniquely efficient operational profile. Owing to the system’s rapid heat-up time, thermal mass utilisation, and controlled heat distribution, the JustHeat system is typically active for only 20 minutes within any operational hour. Consequently, the system operates with an effective efficiency greater than 100% relative to conventional systems when compared based on energy input per hour of equivalent thermal comfort delivery.

This white paper draws upon experimental data, scientific literature, and case studies to establish JustHeat’s superior performance, concluding that it offers up to 75% energy cost savings and up to 90% lower carbon emissions, based on modelling and experimentation at Haydale’s demonstration room.
