Heat invisibly and save energy

Screed Floor Heating

A cozy warm home

Warm feet all winter long! With the energy-saving Floor Heating, you have warm feet and also save on heating costs. The water-based Floor Heating is invisibly installed in the floor and distributes the heat over the entire floor. This way, it heats the room evenly and creates a comfortable living climate. PLUS: No more annoying radiators.

As a low-temperature heating system, alternative and energy-saving systems such as heat pumps, biomass, or thermal solar energy can be used with Floor Heating. Variotherm Floor Heating systems also work with gas.

The Floor Heating.

Five systems for all construction requirements

Continuously save energy.

In a water-based Floor Heating system, the aluminium multi-layer composite pipes (VarioProFile Pipe) are laid over the entire floor area: This means they use the expansion for heating and warm the room evenly. And: A Floor Heating is a Low Temperature System and operates with low flow temperatures between 26 and 38 °C – depending on the outside temperature. This saves energy.

 

In comparison: Radiators emit heat to the room only at specific points due to their small size and therefore require a flow temperature of up to 60 °C.

Wherever a screed is applied, our four models also perfectly adapt to the structural requirements. 
Each of these complete systems meets the highest standards in an equivalent manner.

Reduce heating costs.

Thanks to the Radiant Heat:

The room air temperature can be lowered by up to 2 °C compared to convection heating. And we still feel comfortable. 

Every degree lowered in the room saves about 6% in heating costs per year.

The best floor coverings for floor heating

The thicker the flooring, the slower the heat transfer, as the floor needs to be heated for a longer time. Materials with high thermal conductivity, such as tiles and natural stone, are particularly suitable. The thermal resistance should be a maximum of 0.15 m²K/W, with an optimal value of ≤ 0.1 m²K/W, as also recommended by Variotherm. In principle, almost any flooring can be installed as long as it is suitable for floor heating. Good advice helps to find the ideal combination of design and efficiency.

Accuracy and Installation

All Variotherm Floor Heating systems were developed by experienced professionals for practical use. Therefore, they are flexible and quick to install. Every step and action is thought out in detail and tested in practice. This saves time and money during installation!

Pipe laying in the VarioRoll system.

Installation example

The floor heating is laid continuously with a pipe spacing of 100 mm. In this example, a meander laying pattern was chosen in front of large glass surfaces or glass doors, which extends approximately 1 m into the room. This results in a slightly higher surface temperature in front of the glass surfaces.

 
 
 

Frequently Asked Questions

The water-based underfloor heating is invisibly installed and warms the room across the entire floor. The room heats up evenly, creating a comfortable living climate. Obtrusive radiators are a thing of the past.

A floor heating is medically harmless. This is because varicose veins are not caused by heat, but by weak connective tissue and constant sitting. Well-adjusted floor heating systems have a surface temperature of only 22 to 29 °C and are therefore not harmful to health.

The maintenance-free floor heating systems are invisibly installed in the floor – no more disruptive radiators. The heat is evenly distributed over the floor, making the room comfortably warm in a short time. With floor heating, you can save up to 25% on heating costs.

In principle, all floor coverings that are approved for underfloor heating systems can be used: tiles, stone, laminate, parquet, linoleum, or carpet. Important: The thermal resistance of the floor covering should not exceed 0.1 m²K/W, as thick or poorly conductive coverings extend the heating time.
