Why choose ECOFLOOR heating cables and mats for underfloor heating?

Low running costs: efficient use of energy thanks to the radiant heating principle, ideal when combined with renewable energy sources
Cost-effective heating: the ability to control each zone and room individually
Rapid response to temperature changes: very rapid heat-up compared to hot-water heating
Part of a smart home: can be controlled via systems such as Loxone
Zero maintenance: cables and mats do not require regular servicing
Long service life: unlike boilers and pumps, electric underfloor heating will last a lifetime

We stock the following heating cables and mats for underfloor heating

We’d be happy to help you choose the right model.

What do the various abbreviations mean?

Ideal for energy-efficient buildings

Electric heating responds flexibly to changes in temperature; no hot-water system can match this speed. What’s more, it ensures an optimal distribution of air temperature between the floor and the ceiling. We’d be happy to suggest a suitable solution for you.

Temperature control via a smart home system

Electric radiant heating is quiet, maintenance-free, emission-free and energy-efficient. The key to its efficiency is smart regulation – a correctly selected thermostat precisely regulates the temperature in every room, adapts to the time of day, your presence and the weather, and prevents unnecessary overheating. Integration with smart home systems is, of course, a given.

You’ll use 18–24 per cent less electricity

Over the past 35 years, thousands of homeowners have freely chosen electric underfloor heating. The reasons? Reliability, zero maintenance and lower heating bills thanks to the radiant heating principle and the ability to easily, quickly and conveniently control the intensity and duration of heating in individual rooms.

No servicing required and a lifetime guarantee on ECOFLOOR heating cables

ECOFLOOR heating cables are a top-of-the-range product that undergoes several stages of meticulous testing. They require no maintenance and, thanks to their exceptional reliability, we provide a warranty covering the entire lifespan of the layer in which they are installed. And servicing? None! For a heat pump, servicing over 10 years costs around 50,000–100,000 CZK.

You can install underfloor heating in a new-build home for 80,000–90,000 CZK

Direct radiant heating using ECOFLOOR cables and mats is one of the most widely used methods of installing underfloor heating. Another reason for its popularity is its low purchase price – a complete underfloor heating system for a new-build property with an area of around 100 m² can be purchased for approximately 80,000–90,000 CZK.

Cable or mats? It depends on the shape of the area to be heated

These two products differ only in the way they are laid. Installing the cable offers greater flexibility but is more labour-intensive. The mat is suitable for regular surfaces, is easier to lay and ensures an even distribution of power, but is slightly more expensive.

High performance for demanding spaces and wall heating

ECOFLOOR heating mats offer an effective solution even for spaces with higher heat loss. For conservatories, rooms with large glazed areas or wall-mounted heating systems, high-output mats are the ideal choice, ensuring a faster rise in temperature and effective heating of the structure.

Frequently asked questions about heating cables and mats for underfloor heating

Ecofloor systems are primarily designed for installation using the so-called ‘wet method’, i.e. in concrete, anhydrite or adhesive mortar. These materials ‘envelop’ the cable and ensure that heat is dissipated across the entire surface of the heating cable. At the same time, they distribute heat across the area between the cable loops to ensure the floor surface is heated evenly. It is also important to choose floor coverings that are suitable for underfloor heating. For use with heating cables, glued floor coverings such as tiles, glued vinyl, PVC or even carpet are more suitable. Adhering the covering ensures perfect contact between the layers and thus reliable heat transfer into the room. For all types of underfloor heating, the general rule is that the entire layer above the heating element should not have a thermal resistance (R) higher than 0.15 m²·K/W.

A lifetime guarantee is provided for underfloor heating in residential buildings and flats. To obtain it, simply register your installation using our online form. The term ‘lifetime’ itself refers to the service life of the structural layer of the floor, to which the heating cable is permanently attached. The lifetime warranty is non-transferable and therefore does not pass to the new owner if, for example, the house or flat is sold. The terms and conditions are set out in detail in the Complaints Procedure and in the lifetime warranty registration form.

It depends on the current or planned floor construction and whether the underfloor heating will be the main heating system or simply provide additional comfort by warming the floor. There are several options, but we can design a solution, if not for all of them, then at least for the majority. However, the most common configuration involves laying the heating cable on top of the floor’s thermal insulation, covering it with a 4–6 cm layer of anhydrite or concrete, and then laying a suitable floor covering on top of this.

You can control these Heating Cables and Mats for indoor underfloor heating using our thermostats

The thermostat is usually located directly inside the heated room and controls the connected heating system based on the monitored parameters (room air temperature, floor temperature). Thermostats can be analogue or digital (programmable), with sensors for both room and floor temperature, and offering various settings and programming options.
