Under-Floor Heating Systems

Walking on Wood supply, fit and guarantees engineered hardwood floors with under-floor heating systems. There are several types of under-floor heating systems, and depending on the system that you choose, Walking on Wood will suggest the appropriate and the most suitable floor solution.

The most important point to realize is that a wooden floor is subject to expansion and contraction, according to the amount of moisture in the local environment. This expansion and contraction is magnified when dealing with under-floor heating as the wood is subject to a higher than usual temperature and degree of moisture loss. For these reasons it is essential to select the correct type of floor and under-floor heating system either water-based or electrical.

During the installation process the environment of the site should have a humidity level between 40%-60% and temperature should not exceed 25 degrees. Furthermore it’s vital to ensure that the pipes are set at a consistent level below the floor covering and evenly distributed to avoid heat spots. The subfloor must be also uniformly dry and have been laid at least two weeks prior to placing the wood floor boards and the sub floor should measure a maximum of 3% moisture content by weight and should be properly leveled. Initially the heating should be increased at a gradual rate to avoid excess shrinkage and cracking of the sub floor and heating temperature should never be set above 25 degree.

Waterbased Under-floor Heating

The benefits of a water-based underfloor heating system are that the heat can be distributed more evenly and at a lower running cost than radiators.

Water is heated by a boiler or other heat source and pumped to manifolds located on each floor, which distribute it around the heating circuits in the various rooms before returning to the heat source for re-heating. Once a desired room temperature has been achieved, the thermostat sends a signal to a valve on the manifold, which is then closed

The following illustrations are examples of how the water-based solutions are installed.

Illustration 2: Floorboards or Joist Subfloor: Structural Engineered Board

Another solution on joist subfloors is to fit a chipboard with integrated pipes to which the 10 mm top solid top layer of wood is directly fitted. There is no illustration of this product.

Electrical Under-floor Heating

Electric under-floor heating has the advantage of being fitted under our engineered wooden floors without the need for leveling compounds. It is particularly well-suited for installation in projects where a low build height and rapid heating reaction time are required. Mats are available in several sizes depending on the supplier. When fitting an electrical under-floor heating system, Walking on Wood suggest a floor solution with Structural Engineered Boards or Engineered on Site with Ply or Chipboards and a solid wood top layer.
