7 Most Frequently Asked Questions About Underfloor Heating Systems

Underfloor heating systems stand out among modern heating solutions by offering comfort, aesthetics, and energy savings all at once. However, those considering this system for the first time or looking to upgrade an existing one often have many questions. As KAS Therm, we’ve compiled the 7 most frequently asked questions about underfloor heating systems and their detailed answers for you.

1. How exactly does an underfloor heating system work?

An underfloor heating system operates by circulating hot water through special pipes laid beneath the floor. This method radiates heat upward from the floor, ensuring uniform warmth throughout the entire space. Unlike radiators, which concentrate heat in a specific area, it provides balanced heat distribution across the room.

At KAS Therm, the special pipes and distribution systems we use are designed to ensure maximum efficiency and durability.

2. What is the difference compared to a radiator system?

Radiator systems heat the air, which often causes warm air to accumulate near the ceiling while the floor remains cooler. Underfloor heating, on the other hand, heats the space from the floor up, providing consistent warmth.

Advantages:

• Same comfort level at lower temperatures (e.g., 30–40°C)
• Invisible, providing aesthetic advantages for interior design
• Healthier indoor air due to reduced dust circulation

3. Where can underfloor heating systems be used?

Underfloor heating systems can be easily used in residential, commercial, and institutional buildings. Most common applications include:

• Apartments
• Villas and detached houses
• Offices
• Shopping malls
• Hospitals, schools, and other public buildings

They are suitable not only for new construction projects but also for renovations.

4. Is underfloor heating suitable for all types of flooring?

Yes, underfloor heating systems are compatible with most types of flooring. They can be used with ceramic tiles, laminate, stone, marble, and vinyl coverings. However, since each flooring material has a different thermal conductivity, choosing the right material is essential for maximum efficiency.

KAS Therm experts assist users in determining the most suitable system configuration based on the floor covering.

5. How is the energy consumption does it really save energy?

Since underfloor heating systems operate at lower temperatures, they generally consume less energy compared to traditional radiator systems. And because they heat the space evenly, shorter operating times are sufficient.

Average energy savings: Can range between 15–30%.

KAS Therm systems optimize energy usage further through high-efficiency pipe technology and smart control systems.

6. Does an underfloor heating system require maintenance?

Yes, but maintenance requirements are quite low. With quality materials and proper installation, the system can operate smoothly for years.

Maintenance checklist:

• Pressure control of the system
• Inspection of manifolds and connection points
• General check-up once a year (especially in boiler-connected systems)

Thanks to their long-lasting structure, KAS Therm products offer maximum safety with minimal maintenance.

7. Can an underfloor heating system be installed in existing buildings?

Yes, underfloor heating can be installed in existing buildings as a “retrofit” application. It may require raising the floor level slightly. In such projects, thin pipe systems and special insulation solutions are used to minimize any issues.

KAS Therm offers tailored system solutions for renovation projects, allowing you to enjoy the comfort of underfloor heating without making major changes to your living space.
