what is haydale graphene heating?
Most people assume underfloor heating means ripping up floors, laying pipes, pouring screed, and weeks of disruption. Haydale's JustHeat system changed that completely.
JustHeat uses graphene-enhanced heat mats (less than 2mm thin), powered by Haydale's patented HDPlas® plasma functionalisation technology. They install directly over your existing substrate and under your chosen floor finish.
They reach 30°C in 75 seconds, convert up to 95% of input energy into usable room heat, and carry a 10-year Haydale product warranty. Supply and controls are installed to Haydale's specification for your property.
We're the only certified Haydale installer across Carmarthenshire, Ceredigion and Pembrokeshire.
