Floor heating

Underfloor heating is a modern and incredibly efficient heating method that radiates heat from the floor up through the room. This type of heating system uses low-temperature water or electricity to heat the floor. Underfloor heating provides even heat distribution and creates a comfortable warmth that starts at your feet. It is both energy-efficient and contributes to a healthy indoor climate as it reduces the risk of dust accumulation.

Electric Underfloor Heating

Electric underfloor heating, also known as electrical floor heating, is an efficient heating system that uses electric energy to heat the floor of a room. The system operates by running electricity through thin, resistant heating cables embedded beneath the floor covering. As the current passes through these cables, they produce heat, which then spreads upwards and out into the room.

The working principle of electric underfloor heating is based on the principles of electrical resistance and heat conduction. The electrical resistance in the heating cables creates heat, while the heat conduction in the floor covering helps to spread the heat evenly over the entire floor surface. It's a quiet and invisible system that provides comfortable warmth from the floor upwards.

Benefits of electric underfloor heating include rapid heating, easy installation, and the ability to control temperatures individually in different rooms. Electric floor heating is particularly suitable for smaller rooms such as bathrooms, where it creates a comfortable and luxurious feeling. However, it's important to note that it may be more energy-consuming than water-based underfloor heating, depending on insulation and energy prices.

Water-Based Underfloor Heating

Water-based underfloor heating is a heating system that uses water to transport heat from a heat source to the floor of a room. The system consists of a network of pipes embedded in the floor structure, through which the heated water circulates and releases heat to the room.

Underfloor heating construction in water-based systems typically begins with a heat source, such as a heat pump or a gas or oil boiler. This heat source warms the water, which then circulates through the pipe system under the floor. As the water moves through the pipes, it gives off heat to the floor covering, which then distributes the heat upwards and out into the room.

A crucial element in this underfloor heating system is the thermostat, which controls the water temperature to ensure a constant and comfortable room temperature. Additionally, the system is designed to heat the water to a lower temperature than traditional radiators, making it more energy-efficient. Water-based underfloor heating is known for its comfort and efficiency. It's ideal for larger rooms and can easily be integrated into new buildings or major renovations.

Where can you use underfloor heating?

Underfloor heating can be installed in various rooms and under different types of floor coverings, but there are certain factors to consider. Installing underfloor heating requires careful thought and planning to ensure efficient and comfortable heating.

Bathrooms are ideal spaces for underfloor heating, as it provides a luxurious sensation of warmth underfoot on cold tiles. Underfloor heating in the bathroom can be particularly pleasant in the winter months, and it can also help dry wet areas faster, reducing the risk of mold and dampness.

Underfloor heating under tiles is also a popular choice. Tiles are effective at conducting heat, making them an ideal choice for underfloor heating. The heat from the underfloor heating system will efficiently transfer to the tiles, which then distribute the heat evenly across the room.

When considering the installation of underfloor heating, it's important to consider the insulative properties of the floor. Highly insulated floors will retain heat better, whereas low-insulated floors may require a more powerful heating system. Additionally, consideration must be given to whether the floor can withstand the temperature changes brought about by underfloor heating. Some materials may shrink or expand with temperature changes, which could lead to damage over time.

It's also important to consider the energy aspect of choosing underfloor heating. While underfloor heating can be more energy-efficient than traditional radiators, energy consumption will vary depending on insulation, type of flooring, and the size of the area to be heated. It's therefore recommended to consult a professional before installation to ensure the system is designed to meet your specific needs.

Underfloor heating for low construction height

Underfloor heating for low construction height is a particular type of underfloor heating construction designed to fit into buildings where there is limited space between the floor and the underlying substrate, or where the floor level needs to be kept as low as possible. This type of underfloor heating system operates in the same way as traditional underfloor heating systems, but it is designed to be thinner and more compact. The heat sources, which can be either electric cables or water pipes, are typically closer to the floor surface, allowing the heat to spread more quickly and evenly.

A significant advantage of underfloor heating for low construction height is that it can be installed without having to make major structural changes. This makes it an ideal choice for renovation projects, especially in older buildings where the height between the floor and the ceiling may be limited. Another advantage is that underfloor heating control can be more precise with this system. Because the heat sources are closer to the floor surface, the heat can react more quickly to changes in thermostat settings, making it possible to achieve the desired temperature more quickly.

The underfloor heating thermostat plays a crucial role in this process. It constantly monitors the room temperature and adjusts the heat from the underfloor heating system accordingly. This ensures that you always have the right temperature, and that the system operates as efficiently as possible. Additionally, it contributes to optimizing energy consumption, which can lead to significant energy savings over time.

What is the temperature of underfloor heating?

Underfloor heating temperature is an important aspect when installing and using an underfloor heating system. Depending on the type of floor and the room's use, the optimal temperature varies. Generally, the recommended floor temperature is around 20-27 degrees Celsius, but for certain floor types like wood and parquet, it's often lower to avoid damaging the material.

Underfloor heating control plays a central role in maintaining the correct temperature. This is usually done using a thermostat, which is designed to monitor and adjust heat output based on the set temperature parameters. A correctly set thermostat ensures that your underfloor heating system operates efficiently, maintains a comfortable temperature, and minimizes energy waste.

Parquet Heating is a particular consideration, as wooden floors can be more sensitive to temperature changes than, for example, tiles. For parquet floors, it is generally recommended that the surface temperature not exceed 27 degrees Celsius to avoid drying out or deforming the wood. This temperature limit can vary depending on the type of wood and the manufacturer's recommendations.

If you use a thermometer to control the heat in your underfloor heating system, it's important to place it correctly to achieve accurate measurements. This is typically somewhere in the room away from direct sunlight, other heat sources, and drafts. Also, remember to check and adjust the settings regularly to ensure the system is functioning as it should, and that you get the most out of your underfloor heating.

How to manage the installation of underfloor heating

Installing and mounting underfloor heating is a process that requires precision and an understanding of the room's heating needs. This process, which involves several steps, starts with thorough planning of the system's layout, taking into account factors such as the size of the room and the type of floor. For instance, when looking at the construction of a wooden floor with underfloor heating, there should be proper insulation between the heat sources – this could be electric cables, water pipes, or even underfloor heating mats – and the wood.

Before getting started, it's important to consider the cost of underfloor heating. The price varies and depends on several factors, including the type of system, size of the heated area, and installation costs. While some may see it as a significant investment, the benefits in terms of increased comfort and potential energy savings can make it worth it.

Floor Heating Mats are a good alternative to traditional systems, especially in rooms with limited space or for renovation projects. They are easy to install as they come as a ready-to-use unit that just needs to be rolled out on the floor, and they can be a cost-effective choice depending on your project. Although some skilled DIYers can handle the installation, it's often recommended to use a professional. This ensures the system is installed correctly and operates optimally. A professional installer can also provide advice on the best system for your needs and ensure compliance with building regulations and standards.
