Process of Underfloor Heating Installation in London

Step 1          

When the drawings and design are completed, it is time to choose the position for the manifold based on the project scope. If the design shows the pipes coming through the wall, holes will be drilled at this step. Also, preparation of the subfloor will be needed.

Step 2

This includes:

  • Applying thermal primers to the subfloor.
  • Laying down of boards and sealing by using waterproof tape.
  • Adding the expansion joints to allow a certain amount of movement of the screed.

Step 3

We then install the manifold in line according to designs and drawings, then connect it to the existing water supply.

Step 4

We lay out the pipes, fix them, and ensure that pipes stay in place during the remaining process. After that, we connect the pipes to the manifold.

Step 5

At this step:

  • We craft a precise mixture for conductivity and strength.
  • Levels will be created by using that mix.
  • We add the mix and smooth the surface.

Step 6

After completing the above steps, it is time for the flooring to be laid down.

Step 7

Once the installation is complete, we turn it on for you to enjoy the benefits.
