Water Underfloor Heating Systems

Water, also called wet or hydronic underfloor heating systems are a popular choice for extensions and new constructions. The system uses water for heating, so it can be linked to virtually any heat source from a standard boiler to newer sustainable technologies, such as solar thermal energy or heat pumps.

Each system we provide is tailored during the project’s design stage to get an optimal balance between the system performance and efficiency. Once complete, the lifetime warranty on our pipe provides true peace of mind that the system will continue to perform.


The Warmup Total-16 Low Profile System is perfect for renovation projects and off-plan installations of Underfloor Heating, adding only 16mm to the floor build up.


Clypso Floor System

What Is the Cost of a Water System?

Water underfloor heating is a highly cost-efficient heating system to run as it uses much less energy than a central heating system. Wet underfloor heating emits enough energy to bring your room to your comfort temperature at flow temperatures of 30-40 degrees. This is significantly less than the temperatures required by conventional radiators to bring your room to comfort temperature (60-70 degrees). This is due to the fact that hydronic heating systems spread the heat evenly across the floor surface and emit radiant heating through the objects of the room.

Water systems are particularly popular in energy efficient new build houses. You can calculate the running cost per m2 of your wet underfloor heating system here.

Water underfloor heating is usually installed within the subfloor construction of a building. Before starting the installation make always sure to read the installation manual and follow it every step of the way. The area must be dry and insulation conform to building regulations or practice and again, laid as per manufacturer’s instructions.

The most common underfloor heating systems used with new-builds and renovations where floor heights are not an issue are the Clypso System and Total-16:

  • Clypso System is designed for floating screeded floors and does not get affected by changes in the floor covering weather wood, carpet or vinyl. Total-16 again is popular for its low build solution. The system features a 12mm pipe and 16mm total build-up with straight boards supplied with integrated aluminum heat diffuser plates.
  • Total-16 water system can be installed onto either concrete or wooden sub-floors and under almost any floor finish. Total-16 is laid down on the subfloor and it, therefore, is fast to install and it suits both new-builds and renovations.

If you are looking for an easy and quick installation of a wet system Warmup also offers a water underfloor heating kit. The kit is called HydroPack and it allows for a fast installation of a wet underfloor heating containing everything you need to install the system in hours.
