LK Underfloor Heating is the perfect choice for new builds and renovation. A simple and smart system for underfloor heating in all environments. LK solutions for installation in wooden joists, embedding in concrete, and for load-bearing floors. LK Underfloor Heating is the perfect choice for new builds and renovation.

LK offers complete solutions for outdoor rooms, single rooms, and renovation requiring a low installation height. LK has developed and refined our underfloor heating system to make it even more comfortable, safe, and economical with minimum environmental impact, as well as easy to install.


The LK AtHome app allows you to control and monitor your underfloor heating and water safety system via your mobile phone, tablet or computer. The app has a user-friendly interface that makes it easy to control and monitor all functions, for example raising or lowering the temperature or shutting off water remotely. If something goes wrong, the app will alert you by sending a push notice. Safe and secure.

LK AtHome is compatible with LK’s ICS.2 heating regulation system and the LK Water Safety System WSS, when the LK Webserver accessory is installed.


  • For new-build and renovations
  • Ideal for ground-slab or setting in screed
  • Installation height: 0 mm for new-build, 55 mm when laying on the pre-insulated floor
Underfloor heating embedded in concrete is suitable for both new construction and renovation. When the heating circuits are embedded in the concrete, the underfloor heating installation does not increase the height of the floor. With renovation and rebuilding projects, the circuits are normally laid on top of existing floors and covered with self-levelling screed. The construction height varies depending on which system is chosen.


  • Ideal for renovation
  • Cuts downward heat loss
  • Suitable under all types of the final flooring
  • Low installation height: from 25 mm
The insulated, pre-grooved panel is only 16 mm thick and is installed over existing floors. The heating pipe loops are simply pushed into the panel grooves, which is entirely covered by a bonded aluminum plate; heat from the pipes is spread evenly across the entire floor surface, with little downward heat loss. Load bearing flooring is then installed directly on top of the panel.
Underfloor heating

Underfloor heating is known for providing great comfort while consuming less energy than normal radiators. It's worth placing these water pipes or electric heating cables under the floor! Find out about some of the most important benefits of installing underfloor heating in the description below.  Underfloor heating is becoming more and more popular, especially with those building their own new homes. The incentive is comfort, no visible heating elements, vertical temperature distribution in rooms and emphasized by many, lower heating costs than when using conventional heaters.

Investors often choose water underfloor heating which is more expensive to install but offset by lower running costs. It aslo takes longer to assemble but the costs of running electrical underfloor heating are almost twice as high.



How to plan underfloor heating in advance?

The use of underfloor heating is best foreseen before building a house. There will then be no trouble with the height of the floors and the need to level them in rooms with and without heated floors.
Heated floor - how not to lose any heat?
The heated floor must be protected against heat loss, so thermal insulation boards made of rigid foamed polystyrene boards or mineral wool stiffened with resins are laid on an even surface. To improve the work, special insulation boards glued to the foil - rolled from a roll - are often used. The foil is printed with a grid that facilitates precise positioning and fixing of the pipes.


Water underfloor heating vs electric floor heating?

When choosing between water floor heating and electric floor heating, we should be aware that electricity is more expensive to run, so we will pay a lot for heating with electricity in the long term. But on the other hand, the cost of buying heating cables or heating mats will be lower than the elements necessary for the water installation. We will also avoid operational problems that occur when the water floor heating system is not made correctly. Electric heating is much simpler, so operational errors are less common. The advantage of such a solution is also the possibility of heating the floor without having to run the heating system, for example during transition periods - spring and autumn.


Underfloor heating - comfortable and economical

Heat exchange between the heating device and the environment occurs primarily in two ways: by radiation and by convection Thermal radiation is the transfer of energy of electromagnetic radiation, the source of which is everybody with a temperature above absolute zero. Convection is the transfer of heat, i.e. the heat exchange that occurs as a result of body movement (in this case air in the room). Unlike ordinary radiators, a floor heated by water pipes or resistance wires gives off heat mainly by radiation. When the floor is warmer, less heat from our bodies radiates towards it, so less heat from the environment is needed so that we are not cold.


In what rooms should underfloor heating be installed?Is underfloor heating suitable for all rooms?

One of its features is the large thermal inertia - the temperature of such a floor "radiator" changes slowly. By the time you turn on normal heating and start to feel the heat it takes a long time, with underfloor heating the process is faster and the results can be visible for a long time after it is turned off.


Where to begin? - installation design and good floor insulation

There are 3 different types of underfloor heating. Usually it's just a concrete heating plate with embedded heating elements. In addition to water technology, i.e. covering pipes or cables with cement or anhydrite screed, systems for wooden floors are used, for dry installation.
