Find out about underfloor heating with Butech

Thanks to its winning combination of energy-saving efficiency and aesthetic appeal, this heating solution is becoming more and more in-demand

You know that moment when you come in the house in winter, and the first thing you do is take off your shoes? And the second your feet come into contact with the floor, the cold chills you to the bone? In today's post, we'll explain how underfloor heating systems combat cold temperatures in the home.

What is underfloor heating?

With this heating system the heat is emitted from the ground up, evenly across the whole surface of the floor. Because the heat rises up, it doesn't get lost in the ceiling, keeping the room at a pleasant temperature for longer.

How does underfloor heating work?

It's plain and simple. There are two types of underfloor heating: hydronic (wet) with a system of water pipes under the floor that heats the floor and emits warmth; and electric, with an electrical circuit that uses heating resistors to transform energy into heat. Users can switch the system on or off using a touch screen, selecting the desired temperature.

Advantages of underfloor heating

The highlight? Walking in comfort on a warm floor. Other benefits of underfloor heating include:

  • It warms your feet - the part of your body most sensitive to the cold - and keeps your upper body cooler.
  • It heats the room in use, which means you don't waste energy heating the air at the top of the room.
  • It prevents air currents, reducing dust movement and consequent health problems (allergies).
  • You don't need radiators, which means you gain space, improve the look of the room, and make it safer.
  • It's silent.

How is underfloor heating installed?

It depends which system you go for, but generally speaking it works like this: Firstly, non-compressible thermal insulation is installed along with the heating system, which uses either electrical resistance or water pipes. For the latter, a guide is used to position the pipes. Next, the regulating layer is installed to offer protection from the flooring. This will be thicker for a wet heating system. Finally, the tiles used for the flooring are placed over the top.

One thing to note is that whilst Butech's electrical underfloor heating only requires one thermostat per room, a hot water (or wet) system requires a boiler, pipe manifold, valves and other water system elements and temperature control systems.

How thick is underfloor heating?

This varies depending on the system used: from a thickness of just 2 mm for Butech's underfloor heating, to several centimetres for a wet system. These thicknesses don't include the thermal insulation layer, which is an essential for these heating systems.

Butech underfloor heating

The PORCELANOSA Group engineering firm offers electrical underfloor heating which allows independent and fully customised temperature control in each room, and comprises two elements:

  • 10GM Thermostat: an ultra-slim design fitted into the wall (16 mm), with automatic temperature controls via SmartGeo™, a smart technology that learns your daily routine and the location of users via background communications with a mobile app; leading to significant cost and energy savings. Plus, you can look at charts to monitor your energy costs.
  • Underfloor heating mat/mesh: with 150 W/m². The mesh is ultra-thin (1.8 mm), featuring double insulation to make it exceptionally resistant. The self-adhesive mesh mat has an excellent grip, keeping the cabling completely flat. The 50 cm width of the mat makes it easier to distribute along the floor in parallel strips; ideal for all types of spaces.
