One common problem that can occur at installation is the presence of air in the loops — this occurs when they are not flushed properly prior to being used for the first time. Each loop needs to be flushed individually by opening the valve that connects it to the manifold to ensure that no air is present in it.
Wet underfloor heating systems tend to be covered in a layer of screed that assists with insulation and helps the heat generated to be felt more quickly. There are two forms of screed that might be used: a semi-dry trowelling screed and a fast-flowing liquid screed that can be pumped over the heating pipes to a prescribed depth.
Consult with an expert to ascertain which type of screed you should lay, and how deep it should be. Ensure that the pipes are securely fastened and that the insulation is lying flat on the subfloor before applying the screed. Because it is rendered useless if it develops a crack, and it will be expanding and shrinking in accordance with the heat, expansion joints must also be installed to facilitate that movement.
Once laid, the screed must be allowed to dry naturally which shouldn't take more than seven days before the heating system is turned on. An electric system sounds as though it should be relatively easy to install, given that it comes in the form of mats that need to be positioned underneath the areas to be heated. However, nothing that involves electricity is ever simple, and you should ensure that you take extra care in ensuring that the installation goes smoothly.
Once the floor is out of the way and the insulation is laid, rolling the mats out in the areas you'd like to heat is a relatively simple task. Simply secure them in the way the manufacturer suggests — some employ doublesided sticky tape, for example. You will also have to fit a floor sensor that connects to the thermostat so that you can tell what temperature the floor is running at. The floor sensor should sit on the floor close to the wall below the thermostat, taped or fastened in place to provide a correct reading every time the thermostat is consulted.
The final connection of the system to the main electrical supply should always be performed by a qualified and experienced electrician. This ensures that any immediate issue you come across will likely be down to something like a faulty wire or connection, rather than a mistake made during the installation process. Electric underfloor heating systems are sometimes covered in a layer of screed that assists with insulation and helps the heat generated to be felt more quickly.
The two most common problems associated with the two systems have been covered already: air in the pipes of a wet system and faulty wiring in the electric system. Once the installation is complete, allow the screed to dry as instructed before turning the system on, as this might damage it and cause cracks to develop.
Otherwise, there is little aftercare that needs to be done to either type of heating system — this is one of the factors that make them such an attractive heating option. If the system stops working suddenly, contact the manufacturer, who may recommend that an electrician or plumber comes to look at it if the problem has nothing to do with the product itself. Whichever underfloor heating system you opt to install, the initial setting-up of it should be a simple task once you understand everything that's involved in the process.
Truth be told, it's not easy to warm the actual tiles themselves without installing underfloor heating. The good news is that tiles are an excellent type of flooring to conduct heat. If you do have the opportunity to install a new floor and can invest in the underfloor heating, tile is a great option. For those of you who are stuck with your current tile flooring for the foreseeable future, we have a few tips to help you fight the chill. Start with socks.
This is the obvious solution for anyone looking to protect chilly feet from winter nights. Socks or slippers will ensure that your toes never have to endure the hideous shock of hitting icy tile in the morning, and they'll add a bit of cushion for your joints too bonus!
Now, if you do end up championing socks this winter, invest in some wool socks. Wool has the ability to repel moisture, whereas cotton will trap it and leave your feet both cold and wet. Change the Scenery. You can use a little imagination for a fashionable solution to cold tile. Get some winter area rugs or runners to spread across the floor. The redecoration will give you the opportunity to change things up a bit while giving your feet something more inviting to walk on. As the base expands in relation to the tiles they try to move slightly further apart stretching the grout joints.
Cementitious products are inherently weak in tension and the bond onto the tile edge can fail. One of the most common reasons for problems with the installation of an undertile warming system is damage made during fitting. When covering the wires with adhesive it is quite easy to accidentally cut a wire with the trowel.
Cement-based adhesives and grouts set hydraulically as water is involved in the hardening reaction. If the adhesive is allowed to dry out before it has properly hardened it will tend to be weak and crumbly. It is important that the heating system is off when tiles are fixed and remains off until the adhesive and grout have fully cured. Our highly polymer-modified levellers, adhesives and grouts have enough flexibility when set to accommodate thermally induced movement.
A floor leveller can be used to cover and protect the wires that otherwise could get damaged during application of the adhesive, and can stabilise movement in the floor. For solid substrates: Prime with weber PR and allow to dry. For wooden substrates: Ensure it is capable of supporting the expected load and probable dynamic load, without excessive deflection.
You can take up existing boards and stiffen them with noggings to add extra strength. Alternatively, extra rigidity can be achieved through overlaying the existing timber boards with either WBP plywood or tile backer board. Plywood should be at least 18mm thick, primed on the reverse face and edges with weber PR and screwed every mm.
Tongue and groove or floorboards must be screwed to joists using two screws per board at every joist. All boards should be primed with weber PR All joints between boards should be filled with weberjoint silicone sealant to prevent leakage during application.
Install underfloor heating system in accordance with the manufacturer's instructions and test that it works. Turn it off and allow to cool. Apply weberfloor flex self-levelling compound up to 50mm deep or until the warming elements are covered by at least 3mm 10mm minimum for wooden substrates.
Allow 3 hours before foot traffic. Fix the tiles into a bed of weberset pro lite - rapid , weberset rapid SPF or weberset SPF at least 3mm thick 5mm thick for wooden substrates.
