Frequently asked questions about underfloor heating

What are the advantages of underfloor heating compared to traditional heating systems?

Underfloor heating offers numerous advantages over conventional heating systems. It provides even and pleasant warmth that rises from the floor and reduces dust circulation, which is particularly appreciated by allergy sufferers. By eliminating radiators, it also allows for more design freedom in your home. With lower operating temperatures, it is energy-efficient and can lower heating costs.

Reitbauer Haustechnik's online shop offers a variety of underfloor heating systems and accessories to suit different needs and budgets. Each product is accompanied by comprehensive consultation to help you make the best choice for your specific requirements.

What are the different types of underfloor heating systems?

There are mainly two types of underfloor heating systems: hydronic (water-based) systems and electric systems. Hydronic systems use warm water flowing through pipes beneath the floor to generate heat. Electric systems use heating mats or cables installed beneath the flooring. Each type offers specific advantages depending on individual requirements and available budget.

What are the installation costs for underfloor heating?

The installation costs for underfloor heating vary depending on the scope of the project and the type of heating system. Electric systems are generally more cost-effective and easier to install, with costs ranging from 20 to 30 euros per square meter. Hydronic systems can cost between 40 and 80 euros per square meter due to their complexity. 

In addition to these costs, there are also costs for a boiler or heat pump if they are not already present. However, it is important to note that despite higher initial costs, hydronic systems are often more efficient and can save on energy costs in the long run. Please note that these are average values and actual costs can vary depending on many factors.

How energy-efficient are underfloor heating systems?

Underfloor heating systems are known for their high energy efficiency. They utilize natural convection, distributing heat evenly and creating a comfortable room climate. As underfloor heating systems operate at lower temperatures than conventional heating systems, they reduce energy consumption and help save on heating costs. 

Furthermore, they improve the energy efficiency of your home by minimizing heat loss. However, efficiency also depends on factors such as house insulation, type of flooring, and correct installation. Consider these factors to fully harness the potential of your underfloor heating system.

Are underfloor heating systems suitable for all types of flooring?

Underfloor heating systems are a versatile heating solution compatible with most types of flooring. Ceramic tiles are an ideal choice as they conduct and retain heat well. Parquet and laminate can also be used, but they should be specifically approved for use with underfloor heating.

Carpets are less suitable as they can insulate heat, but there are special underfloor heating-compatible options available. Vinyl and linoleum need to be tested for their temperature resistance. It is advisable to consult with the flooring manufacturer to determine suitability and maximum surface temperature. We can assist you with this.

How long does it take to install an underfloor heating system?

The installation time for an underfloor heating system depends on several factors, including the size of the room, the chosen heating system, and the condition of the floor. For an average-sized room of around 20 square meters, you can expect 2-3 working days. This includes preparation work such as laying insulation and heating pipes, as well as connecting to the heating system. Keep in mind that after the heating installation and before laying the flooring, the drying time of the screed must be taken into account, which can take up to 6 weeks depending on conditions.

What are the typical maintenance requirements for an underfloor heating system?

Underfloor heating systems are known for their low maintenance requirements. However, regular checks of the heating control and system pressure are essential. An annual inspection by a professional can help optimize performance and efficiency. During the inspection, the system is purged, water flow is adjusted, and any leaks are identified. 

A thorough cleaning and flushing of the system should be done every 5 years to remove deposits. In the case of electric underfloor heating systems, maintenance is even easier as there are no liquid components. However, the electrical connections should be regularly checked. Always ensure that the heating system is functioning properly to ensure a long lifespan.

Are there any special tools or accessories required for installation?

The installation of an underfloor heating system requires specific tools and accessories. Firstly, you will need basic tools such as a screwdriver, hammer, pliers, and cutter. For laying the heating pipes, pipe cutters and bending springs are helpful. Special tacker staples are necessary for securing the heating pipes to the insulation boards. For an electric underfloor heating system, you will need an ohmmeter to check the heating cable. Additionally, a sealing compound is important to protect the electrical connections from moisture. We offer a variety of tool sets and installation kits tailored to the requirements of underfloor heating, making the installation process much easier for you.

How do I regulate the temperature of my underfloor heating system?

The temperature control of your underfloor heating system is usually done through a thermostat, which can be either manual or digital. Modern digital thermostats allow for precise temperature adjustment and even programming to ensure efficient use. There are also smart thermostats that can be integrated into your home network and controlled via an app. It is important to adjust the temperature of the underfloor heating slowly to ensure even heating and protect the flooring. Underfloor heating systems have a slow response time, so abrupt temperature changes should be avoided. Experts recommend maintaining a surface temperature between 20 and 25 degrees Celsius for optimal comfort.

How much area can an underfloor heating system effectively heat?

An underfloor heating system can effectively heat nearly any room area, from small bathrooms to large living areas. However, the exact coverage depends on several factors, including the type of underfloor heating, the heating material used, and the insulation of the room. Electric systems are often better suited for smaller areas, while hydronic systems are typically advantageous for larger areas. Well-insulated rooms allow for more efficient operation and coverage of larger areas. Therefore, it is important to make an accurate assessment of your specific needs and the characteristics of the room to determine the optimal heating solution.

How does an underfloor heating system impact the overall energy consumption of my house?

Underfloor heating systems can contribute to the energy efficiency of your house, significantly reducing your overall energy consumption. Compared to conventional radiators, underfloor heating systems operate at lower water temperatures (around 35-45 degrees Celsius compared to 60-80 degrees for radiators). This means less energy is required to heat the water, resulting in savings on heating costs.

In addition, underfloor heating distributes heat more evenly and efficiently throughout the room. The radiant heat from below creates a pleasant room climate without the need to set the heating to higher temperatures. This further saves energy.

Therefore, underfloor heating is an excellent solution for energy-conscious homeowners and builders who want to save in the long term and contribute to environmental protection. However, it is important to have good house insulation to maximize the benefits of this heating system. With proper installation and maintenance, underfloor heating can lead to significantly reduced energy consumption.
