The underfloor heating dry construction has already demonstrated itself as a modern method of heating that provides warmth in the room and uniform heat penetration. But when applied to wooden flooring, there are compatibility, safety, and durability issues. Let's explore this article to learn how to install floor heating on a wooden floor correctly, what the restrictions are, and how to service such a system to preserve both its attractiveness and functionality.
Compatibility of underfloor heating with wood
Wood is a natural material that reacts to changes in temperature and humidity. This is why, when installing underfloor heating under a wooden floor, it is essential to pay attention to the technical nuances and follow the manufacturer's recommendations.
Technological limitations
The primary concern is the potential expansion or contraction of wood when heated. When the temperature exceeds permissible values, the material deforms:
• gaps form between the boards;
• geometry of the slats changes;
• aesthetic look of the coating is lost.
It can be avoided by keeping the following limitations in mind: the surface heating temperature should not increase by more than 27–28°C.
Manufacturer recommendations
The majority of European manufacturers of wood flooring formally allow the installation of underfloor heating, but define the following mandatory requirements:
• using high-quality heat-treated wood with a minimum content of moisture;
• adequate thickness of the coating (usually not more than 15 mm);
• professional installation, taking expansion joints into account.
Thus, compatibility is quite possible, but by the correct means.
Types of underfloor heating for a wooden base
There are two main types of underfloor heating systems - electric and water. Both can be placed below wooden flooring, but with some characteristics.
Electric
Electric underfloor heating is usually installed in a cable mat or thin film. It heats quickly and can be easily controlled with a thermostat. In wood floors, an infrared film system is typically used, which heats uniformly and poses less risk of overheating. Its advantage is the ease of installation and the possibility of installation with minimal modification to the floor structure.
Water
A water-based underfloor heating system is a more traditional option, where the coolant circulates through pipes installed in the screed or special plates. For wooden floors, this option requires more careful planning, as excess heat can damage the wood. However, with proper design, a water system can be energy-efficient and is particularly beneficial for homes with their own boiler or heat pump.
Care and operation
Proper operation is the key to preserving a wooden floor and the durability of the heating system.
Preventing deformation
To avoid warping or drying out of wood, you need to follow several rules:
- gradually raise the temperature when turning on the system;
- avoid sudden changes in heating and cooling;
- maintain a stable level of humidity in the room (40–60%).
Optimal temperature
The most important thing is not to exceed the surface temperature of the wooden floor above 27–28°C. Higher values not only harm the wood but also reduce comfort, because an excessively hot floor causes a feeling of dryness. The use of thermostats and floor sensors enables precise control of the indicators, ensuring safety.
Conclusion
Underfloor heating on wooden floor is a real and comfortable solution that combines modern technologies and the natural beauty of wood. The main thing is to choose the right type of system, adhere to technological restrictions, and not exceed the optimal temperature regimes. With a competent approach, a warm floor will provide comfort in your home for many years, and the wooden covering will retain its impeccable appearance.
