Wet Underfloor Heating

Installing a wet underfloor heating system is one of the smartest ways to create a warm and inviting home. Unlike traditional radiators that heat the ceiling first, a wet system circulates warm water through pipes hidden beneath your floor. This creates an even, comfortable heat removing cold spots and the need for wall radiators.

Each kit that we stock comes packed with essential components, including A-rated circulation pumps, mixing valves, edge insulation, and smart thermostats that connect to your phone. You can gain even more efficiency by pairing your system with high-quality insulation boards to prevent heat escaping downwards.

FAQs

What is wet underfloor heating?

Wet underfloor heating (also called hydronic heating) is a central heating network that circulates warm water through pipes laid under your floor. It connects straight to your main boiler or heat pump, turning your whole floor into a giant radiator. 

Wet vs dry underfloor heating: what are the differences?

Wet underfloor heating systems use water pipes connected to the central heating, making them cheaper to run in the long term. This is ideal for larger areas, extension builds, or full house renovations. Dry (electric) underfloor heating systems use thin wire mats connected to your mains electrics, which are cheaper and quicker to install in small spaces, but cost more to run. 

Can I lay wet underfloor heating under any floor type?

It works very well under most popular floor coverings, such as ceramic or porcelain floor tiles, natural stone, vinyl, laminate and engineered wood. Materials like tiles and stone conduct heat fastest, but you can check your flooring tog rating in our flooring buying guide to ensure maximum warmth output.
