Underfloor heating works by circulating warm water through pipes embedded in a floor. The large surface area of the floor allows lower temperature water than would be required in a traditional radiator system and generates a more comfortable, even heat.

Chelmer have been designing and supplying underfloor heating systems for over 20 years. They use their extensive expertise to provide a complete underfloor heating package using high quality components and tailored to your project’s individual requirements.

All their systems include full bespoke CAD drawings detailing pipe layout and wiring connections and are backed up with step-by-step installation manuals and free installer support.

Renewable integration
Designed to work with a boiler or heat pump out of the box, connecting a Chelmer underfloor heating system to one of their thermal store cylinders also allows the integration of renewable sources such as solar thermal and wood burning stoves for reduced running costs and a smaller carbon footprint.
