How does an infrared underfloor heating system work?

Unlike water-based systems, which react slowly and require a thick screed, infrared underfloor heating works with electric heating conductors. These are fixed to thin fabric mats or integrated into foils.

The principle is direct floor temperature control :

• The electric current heats the heating elements.
• The heat is transferred directly to the floor covering.
• The floor radiates the energy into the room as mild infrared heat.

This system allows for extremely fast response times . While underfloor heating with water often takes hours to become noticeable, with electric heating mats (especially directly under tiles) you often feel the warmth after just 15 to 30 minutes.

Which system is suitable for which type of soil?

Choosing the right heating mat is crucial for efficiency and protecting the floor covering. We distinguish between two main areas of application:

1. Under tiles and natural stone (wet installation)

Here, mesh heating mats (e.g., from Etherma) are most commonly used. The heating conductors are attached to a carrier mesh.

• Installation: The mat is laid directly in the tile adhesive bed or in the leveling compound.
• Advantage: Perfect for bathrooms and kitchens, as the stone conducts and stores heat exceptionally well.

2. Under laminate, parquet and vinyl (dry installation)

Special heating foils are used for "floating" floors. These are often thinner and distribute the heat more gently to avoid damaging the delicate wood.

• Installation: The foils are simply rolled out onto the impact sound insulation. The floor covering is then laid directly on top.
• Important: Ensure that the manufacturer's approval for your flooring is given for use with electric underfloor heating.

Why electric heating? Advantages for renovation professionals

For architects, planners and building owners, electric underfloor heating is often the number one problem solver when it comes to renovations of existing buildings.

• Minimal installation height: The mats are often only 3 to 5 mm thick. No screed needs to be chiseled out; the floor level hardly increases.
• Maintenance-free: Where no water flows, nothing can leak, clog up with silt, or freeze. The systems are considered maintenance-free.
• Targeted heat: Ideal as a supplement ("bathroom upgrade"). You don't have to heat the whole house to have warm feet in the bathroom.
• Smart Home Ready: Modern thermostats enable precise control via app, schedule and floor sensor.

Professional quality from Etherma and Elbo Therm

In this sensitive area (under the floor, where repairs are difficult), we tolerate no compromises. That's why we carry products from renowned manufacturers:

• Etherma : An Austrian pioneer with over 40 years of experience. Etherma stands for innovative mesh heating mats (e.g., the dipole heating mat, which generates virtually no electrosmog) and robust solutions for indoor and outdoor areas.
• Elbo Therm : Known for high-quality "Made in Germany" products. Elbo Therm offers reliable solutions that are particularly valued for their durability and ease of use.

Installation height: What needs to be considered?

Installation is easily manageable for qualified tradespeople and experienced DIYers. However, it is essential to adhere to professional standards.

1. The surface: This must be dust-free, dry, and level. A primer is often recommended.
2. Insulation from below: To prevent heat from "disappearing" into the basement floor, insulation under the heating mat is essential. Special rigid foam support panels are available that add minimal thickness but drastically reduce the heating time.
3. The sensor: It is essential to install a floor sensor (in the conduit between two heating loops). This protects the floor from overheating.
4. Electrical connection: The final connection to the 230V mains and the thermostat should always be carried out by a certified electrician (observe VDE guidelines).

Frequently Asked Questions (FAQ)

How high are the electricity costs?

This depends on usage. As a primary heating source in poorly insulated older buildings, it can be expensive. However, as a secondary heating source (e.g., one hour each morning and evening in the bathroom), the costs are minimal and often cheaper than firing up a central heating system. Modern thermostats significantly optimize consumption.

Is it possible to shorten the heating system?

The backing mesh (the fabric) can be cut and folded over to adjust the mat to the room. Caution: The heating cable itself must never be cut or shortened!

Is the heater suitable for damp rooms?

Yes, the Etherma and Elbo Therm heating mats in particular are designed for use in bathrooms and wellness areas (observe the protection class). However, when installed in wet areas, they must be professionally sealed and protected by a residual current device (RCD).
