Installing underfloor heating yourself is a rather simple process. If you the handyman type, following the steps listed below should be easy and fun to follow; so…how to install underfloor heating ?
Step 1: Make sure 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 mat. Also, know where you would be positioning your thermostat, as this would the starting and end point of the mat.
Step 2: Once step 1 is done, make sure the floor surface is clean and level. If there are any rough patches, level it out with self leveling 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 mat to run parallel next to 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 starting point.
Step 4: To hold the mat in place, use strong duct tape, hot glue gun or nails attached to mesh, NOT the wire.
Step 5: If you are installing an external sensor ( would be used for bathrooms, cemcrete floors and wooden floors ), 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 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, its up to your own initiative.
Method 1: You can lay tiles directly on top of mat ensuring the tile adhesive goes through the mesh to make contact with concrete floor.
Method 2: Prepare a slurry mixture of self leveling 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, floor surface 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 first usage.
