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 heating pipes provide true peace of mind that the system will continue to perform.

Installation

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

Low-Profile Systems

The most common underfloor heating systems used with new-builds and renovations are the Clypso System and the Total-16 System:

  • Clypso System is designed for floating screeded floors and does not get affected by changes in the floor covering whether wood, carpet or vinyl. The system comes with laminated insulation panels for efficient heating.
  • Total-16 System is popular for its low build solution, featuring a 12mm pipe and a 16mm total build up. With aluminium diffuser plates, it can be quickly installed onto either concrete or wooden sub-floors and under almost any floor finish.

Wet System Kit

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

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.

Running Costs

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.
