Water Underfloor Heating Systems – Efficient, Versatile and Built to Last

Water-based underfloor heating systems (also known as wet systems) come in a range of configurations to suit every type of property and floor build-up. With various pipe sizes, system depths, and installation methods available, we can match the perfect setup for your insulation level and floor thickness.

Low-profile systems start from just 18mm, typically using 12mm water pipes, making them ideal for retrofit projects where floor height is limited. For larger or higher-output systems, pipe sizes can go up to 22mm, though the most popular option remains 16mm diameter with 2mm wall thickness—offering excellent performance and easy installation.

Key Features and Benefits

  • Perfect for connecting to existing central heating systems

  • Suitable for both new builds and renovation projects

  • Compatible with Varme Programmable Thermostats for full temperature control

  • Compact, lightweight, and supplied with all required components for quick installation

  • Available in 12 kit sizes, from 20m² to 240m²
