The JK® system is an in-ground, water-based underfloor heating solution uniquely designed for installation in existing floor constructions, including concrete, screed, or dry-board. Pioneered by JK in 1994, this patented method enables homeowners to upgrade to a modern, energy-efficient, and comfortable heating system without extensive renovation.

Over the past three decades, nearly a quarter of a million homes across Western Europe have benefited from this well-tested solution. JK’s in-house trained installers are skilled in meeting stringent installation standards, ensuring optimal system performance as the primary heat source in any building.

Moreover, the JK® system complies with the latest UK regulations, including PART L, which requires improvements to align with net-zero emissions goals. Unlike traditional underfloor heating methods that involve extensive excavation and concrete work, the JK® system minimizes environmental impact while delivering significant energy savings—making it the preferred choice for sustainable home improvement.
