Installing underfloor heating yourself is a rather simple process. If you are the handyman type, following the steps listed below should be easy and fun to follow; so…how to install underfloor heating?
Easy steps to install
Step 1:Firstly ensure the size mat you purchased is the correct size for your room. Now you need to plan the layout of the mat. Start doing this by doing a sketch of the room with all measurements of the mat. Also, know where you would be positioning your thermostat, as this would be the starting and end point of the mat.
Step 2: Once step 1 is done, make sure the floor surface is clean and levelled. If there are any rough patches, level them out with a self-levelling screed.
Step 3: Now, from the point where you would place your thermostat, roll out the mat to the desired length, then cut the mesh to twist the mat to run parallel next to the rolled-out length, be careful not to cut the wire. You may cut away some mesh if you have excess, this could happen when installing in bathrooms. Continue in this fashion until the desired floor space is covered, ending back at your starting point.
Step 4: To hold the mat in place, use strong duct tape, a hot glue gun, or nails attached to the mesh, NOT the wire.
Step 5: If you are installing an external sensor (which would be used for bathrooms, cemcrete floors, wooden floors, and carpets), this should be perfectly positioned in the middle of the heating wires. If you position it closer to one cable than the other, the temperature would not be gauged properly.
Step 6: If you had purchased an alarm ( ideally you should ), connect the cold tails ( this is the wire at end of the mat which connects to the thermostat ), to the alarm to ensure the mat did not get damaged. If the alarm sounds, you have a problem.
Step 7:To lay your tiles or floor surface: There are 2 methods, it’s up to your own initiative.Method 1: You can lay tiles directly on top of the mat ensuring the tile adhesive goes through the mesh to make contact with the concrete floor.Method 2: Prepare a slurry mixture of self-levelling screed and bonding liquid. Spread this mixture over the mat and leave it to dry. This mixture will get rock-hard. You can now install the floor surface of your choice.
Step 8. Assuming the alarm hasn’t sounded, and the floor surface has been laid, you can now connect the thermostat to the heating system.
In our next blog, we will explain how to connect and position various models of thermostats.
Step 9. Let it dry for a few days before the first usage.
Remember that is very important that none cut or damage the wires, this should be the most important point to remember on how to install underfloor heating mesh mats. If the alarm went on or you suspect that there is a broken wire then stop the installation and find the spot where the wire is cut or damaged.
If you find the damaged part then will be easy to fix this wire with heat shrink and small ferrules. The connection should be waterproof.
