Some tips for underfloor heating installation during refurbishment

Do you dream of underfloor heating in your home? Then we have good news for you, because it is now perfectly possible to install underfloor heating in an old property during renovation work. In this article we will give some practical guidelines.


The many benefits of underfloor heating

The many benefits of underfloor heating are well known: the heat is spread evenly throughout your living space, the supply of lower temperature heat reduces energy costs, you do not need to place large radiators anymore and you will enjoy the extended options in your interior design. Therefore, more and more people opt for unferfloor heating in their new building.

But there is also good news for those who would like underfloor heating in their existing home. Such an installation is perfectly possible if you take into account a number of factors during the renovation work.

Opening up of the floor

The name ‘underfloor heating’ says it all: the pipes are in slots under the floor. That could mean that you may need to open the floor partially. Using the right system the opening of the floor is not needed. If you use Incognito Ambiscreedboard the floor can be finished with a liquid mass and then their ios no need to cut into the floor. After a few days the surface will be suitable for tiles, carpet, wood, laminate or pvc. Because of the the small thickness of the screed you will loose little height.

A wet or a dry placement?

There are two types of underfloor heating: the wet and the dry system. With a wet system the tubes are paced directly into the wet screed, or actually: the screed is poored over the pipes. This screed is reinforced with liquid fiber plaster.

Whith a dry system the heating pipes are recessed in the insulation system in a pre-formed construction of styrofoam or polystyrene. These insulation boards are finished with an aluminum layer. This method allows for faster heat distribution. You can also limit the total height to up to 5 cm in diameter. The dry system is therefore very much of interest for thise working on renovation projects.  Because the tubes are close to the floor surface, the ideal distance between them is 15 cm. This system is perfect for very low water temperature sources such as heat pumps.

Choose a good insulation

During the renovation work, the underfloor heating Glasgow system needs to be combined with a good floor insulation. That way you avoid heat loss at the bottom and cold bridges between your floor and the outside wall. That way the heat stays in the home at a lower height, giving you more warmth using less energy.

Which floor covering is recommended the most?

The flooring plays a role for an optimal operation of your underfloor heating. Natural stone or ceramic tiles do not isolate and are therefore excellent heat conductors. For wooden floors and laminate some conditions apply: wood is a living material that expands and contracts with temperature changes. Therefore, avoid beech, maple or ash: these types of wood react strongly on heat and moisture. To prevent heat loss, it is best to choose wooden floors with a maximum thickness of 18 mm. This way there is direct contact with the heat from the underfloor. In order to avoid moisture problems, a plastic foil is recommended between the surface and the floor covering.
