An underfloor heating system is discreet, leaving you to make the most of all the wall space in a room. It is also an extremely efficient option, and it can help you significantly reduce your energy bills.

Water Underfloor Heating is an energy efficient and affordable alternative to traditional radiator based central heating systems. It uses warm water to heat your home in a far more efficient manner than traditional radiators, reducing heating bills and having less impact on the environment.

Water Underfloor Heating works by turning the floor area into a giant, efficient and invisible heat emitter.
The system is composed of hard wearing and flexible lengths of Pert Al Pert pipe, embedded in the floor, to circulate warm water throughout the property. The warmth from the water is absorbed into the floor substrate, which then radiates into the room above.
Find out moreBecause underfloor heating covers such a large surface area, the water within the system can have a lower temperature (approx. 40°C) than standard radiators require (approx. 75°C). For this reason, water underfloor heating is around 25% more efficient than radiators and up to 40% more efficient when paired with a heat pump!
Underfloor Heating also alleviates cold spots in your room which radiators are prone to and even removes the need for radiators at all, giving you back precious wall space.

All Water Underfloor Heating systems are basically the same, they all pump warm water through pipework in the floor. The main differences being:
What effect does the pipe spacing have?
What are circuits
and zones?
Does the pipe diameter matter?
There are several ways to install the flexible pipework depending on your project needs. We offer various methods to ensure correct pipe spacings are maintained to enable your desired heat output.
The Clip Track system comes in 1m lengths and provides vertical clips the pipe can be pressed into, keeping each coil the correct distance apart. The Clip Track can be secured to the PIR insulation or directly onto an insulated concrete base and covered with a screed.

Our fixing Staples provide more flexibility on the pipe spacing. They are plastic U-shaped clips with barbed ends, which can be pressed directly into the PIR insulation to hold the pipework in whatever configuration is required.

Our DUO Boards are comprised of an EPS400 polystyrene board with a 200micron aluminium foil face to aid with heat distribution. The boards contain grooves pre-cut to 150mm spacings which the pipe is simply pressed into. The boards can be laid over an existing floor substrate and tiled directly over. Available in 16mm (12mm pipe) and 20mm (16mm pipe) depths.

The Egg Crate system provides great flexibility with pipe spacing and easy installation due to their design. They take the form of a plastic sheet with protrusions across the face that grip the Underfloor Heating pipes once pressed together. This system is available for 16mm pipe or 12mm pipe.

Like the Egg Crate system, the Profix system offers a 600x600 plastic tile covered with a repeating eyelet pattern for a 12mm Underfloor Heating pipe to be pressed into. The Profix system also has connecting tabs around the perimeter allowing several panels to be interlocked for easier installation.

Our Solid18 Gypsum Panels come pre-grooved at 150mm centres and offer an easy retrofit solution. The high-density dry screed board acts as a heat conductor to give excellent heat distribution.

Our Spreader Plate solution enables the installation of Water Underfloor Heating pipes in between floor joists. The Spreader Plates are secured directly to the top of the floor joists and offer grooved channels to contain the underfloor heating pipe. With suitable insulation installed beneath, the Spreader Plates also offer even heat distribution to the floor above.

An experienced DIYer should have no issues installing our low-profile panel systems or our in screed systems, some basic plumbing knowledge and general building experience should see you well on your way to completing your install. However, you will need a qualified plumber / electrician to complete all connections to the heat source to comply with UK building regulations.
Generally, though, Water Underfloor Heating systems are installed as part of a larger building project or property renovation and as such the installation is taken care of by the building contractor or employed installer.
We also have an extensive network of Fastwarm® approved installers should you require them.
