With our detailed guide, you will learn how to successfully tackle this task. Installing underfloor heating may initially seem complex, but it offers numerous benefits ranging from increased comfort to energy efficiency. By understanding the process and following the correct installation methods, you can confidently take on this project with assurance and security. With our support, you will be able to create the ideal heat source for your home by successfully installing underfloor heating yourself.

Why Choose Underfloor Heating?

Choosing underfloor heating brings numerous advantages. It is not only efficient and space-saving but also extremely comfortable. By operating at lower temperatures than conventional radiators, underfloor heating can significantly contribute to energy savings and reduce heating costs. Additionally, using underfloor heating improves air quality in your living spaces. It stirs up less dust and allergens compared to traditional heating systems, which is especially beneficial for allergy sufferers. From an aesthetic perspective, underfloor heating offers a clear advantage: it is hidden beneath the flooring and does not interfere with room design. If you are looking for an efficient, healthy, and aesthetically pleasing heating solution, underfloor heating is the perfect choice.

Types of Underfloor Heating

Underfloor heating comes in two basic types: water-based systems and electric systems. Water-based underfloor heating uses pipelines through which hot water flows, evenly distributing heat throughout the room. They are ideal for large spaces and especially efficient when combined with sustainable heat sources such as heat pumps or solar thermal systems. 

In contrast, electric underfloor heating uses heating mats or cables installed beneath the flooring. This type of underfloor heating is particularly suitable for smaller rooms or as an additional heat source in existing spaces since it heats up quickly. Both systems, water-based underfloor heating and electric underfloor heating, have their specific advantages and disadvantages and should be selected according to the individual requirements of your project.

Preparation: What You Need

Properly installing underfloor heating requires careful preparation and the right tools. To ensure that your underfloor heating is installed efficiently and correctly, you will need specific materials and tools. 

These include a tape measure to ensure precise measurements for the area where the underfloor heating will be installed, and a pencil to make markings. A spirit level ensures that your subfloor is even, ensuring uniform heat distribution. A saw can be useful for cutting insulation materials and adapting heating elements as needed. A utility knife is ideal for customizing the underfloor heating mats in the electric variant. 

Naturally, the heating elements, whether water-based or electric underfloor heating, are a central component. Be sure to prioritize safety and use appropriate protective gear such as gloves and safety goggles throughout these tasks.

Step by Step: How to Install Underfloor Heating Yourself

Step 1: Prepare the Floor

Before you begin installing your underfloor heating, proper preparation of the subfloor is essential. Thorough cleaning is a must. Use a broom to remove any dust and dirt from the entire floor area. Check the floor surface for unevenness - if any are present, they must be eliminated using suitable leveling materials. Any unevenness can negatively affect the performance of your future underfloor heating. 

Next, cut the additional insulation precisely. Measure the area accurately and cut the insulation materials accordingly. Lay the insulation carefully, ensuring it covers the entire floor. These steps secure the efficiency of your underfloor heating and form the basis for a successful installation.

Step 2: Install the Edge Insulation Strips

Installing edge insulation strips is an essential part of laying underfloor heating as they ensure thermal separation between the floor and ascending components such as walls, stairs, or columns. The edge insulation strips should be attached so that they rest on the floor and the foil apron faces the room. The foil apron serves as protection against rising moisture and ensures efficient insulation of your underfloor heating. You can use a standard stapler to secure the edge insulation strips. 

Ensure that the strips fit snugly to ensure optimal performance of your underfloor heating. By attaching the edge insulation strips carefully, you create the ideal foundation for an efficient and long-lasting functioning of your underfloor heating.

Step 3: Lay the Tacker System Panels for Your Underfloor Heating

To install your underfloor heating optimally, start by properly laying the tacker system panels. Begin in one corner of the room and carefully lay the panels so that they align flush with the edge insulation strips. This ensures efficient heat conduction and minimizes heat losses at the edges. Next, use robust PE adhesive tape to bond each tacker system panel. This not only increases the stability of your underfloor heating but also provides additional sealing. 

This method reduces the risk of leaks or damage in your underfloor heating, extending the system's lifespan. Each step contributes to ensuring that your heating operates efficiently and without issues. In just a few steps, you can transform your space into a cozy oasis with a self-installed underfloor heating system.

Step 4: Optimal Placement of the Heating Pipes for Your Underfloor Heating

Before you begin laying the heating pipes for your underfloor heating, there are a few important points to consider. The starting point is the manifold, from which the heating pipes will run. Proper positioning and distribution of the heating pipes are essential for the efficiency and performance of your underfloor heating.

According to general recommendations, the heating pipes should be laid at intervals of 10 to 15 cm from each other. This ensures even heat distribution and avoids unwanted cold zones in the room. However, the actual spacing may vary depending on the type of underfloor heating and the specific requirements of your space.

Secure the heating pipes to the system panels using a staple gun and anchor clips. Make sure the pipes are firmly in place but not overstretched. By correctly laying and securing the heating pipes, you significantly contribute to the longevity and efficiency of your underfloor heating.

Step 5: Pressure Test, Consolidation, and Screed - Getting Your Underfloor Heating Ready for Operation

Before moving on to the next phase, it is essential to test the tightness of your underfloor heating. Fill the heating pipes with water and bleed the system to perform a pressure test. This measure ensures that your underfloor heating pipes operate safely and efficiently without leaks or losses.

Once your underfloor heating is leak-free, you can proceed to the next step: preparing the screed. It is important to use a leveling compound specifically designed for use with underfloor heating. After careful mixing, pour and evenly distribute the compound over the surface.

Subsequently, incorporate the screed. After it has fully dried, which typically takes a few days, you can finally install the flooring of your choice. Approximately 2 to 5 days after laying the flooring, your underfloor heating will be ready for operation, and you can enjoy the pleasant warmth it provides.

Common Mistakes When Installing Underfloor Heating

Now that you understand the foundation for installing underfloor heating, it is worth noting common pitfalls. One typical mistake when laying underfloor heating is overlooking insulation. Proper insulation is essential for minimizing heat loss and maximizing the efficiency of your heating system. 

The correct spacing between the heating pipes is also crucial for even heat distribution, so it should not be neglected. And finally, even in a do-it-yourself project like this, the manufacturer's recommendations for your specific underfloor heating model are invaluable. Do not ignore them, as they are your best resource for optimizing the lifespan and performance of your underfloor heating.
