How to Hang a Water Heater on a Drywall?

In this article we explain how to quickly and easily build a reinforced structure from UA profiles for the installation of a water heater in a wall lining.

Tools and products you need:

  • Premium Profile UW
  • Premium Profile CW
  • UA Angle
  • Bolt for UA Angle
  • Premium Profile UA
  • Self-drilling Screw TB 3.5x25
  • Moisture Resistant Gypsum Plasterboard Type H2
  • Tape Measure
  • Chalk Line Marker
  • Pencil
  • Level
  • Tin Snips
  • Drywall Screwdriver
  • Drywall Saw
  • Wrench

Here are the steps we followed:

We start by outlining the axis of the wall lining on the floor and ceiling. We measure the peripheral UW profiles and we fix them to the floor and ceiling using suitable fasteners. The we proceed with the measuring of the end vertical CW profile which we then fix to the wall.

We move on to fixing the UA angles to the UA profiles. We use bolts for UA angles for this purpose. Then we fix the UA profiles to the peripheral UW profiles. Leave the upper UA angle with loose bolts to the UA profile to avoid rigid connection between the partition wall and the main structure. This helps avoiding cracks at the joints due to deformations in the main structure of the building from subsidence, earthquake or sagging of the floor slab.

Then we fix the UA profiles to the peripheral UW profiles.

Using a pencil, we mark the distance at which the horizontal UA profiles will be placed. They will be used for the installation of the water heater in the wall. We fix additional UA angles to the marked areas using bolts for UA angles. We cut two UA profiles to a width of 600 mm (the distance 

between the vertical profiles in the wall lining) and fix them to the UA angles with bolts. For maximum stability and strength of the structure, we fix the free standing vertical UA profile to the wall, using a UA angle and self-drilling screw TB 3.5 x 25 or self-drilling screw TEX LB 4.2 x 13.

We mark the positions at which we will place the fasteners for the water heater and drill holes in the horizontal profiles to fix the fasteners through.

After we have fixed the four fasteners, we proceed to closing the wall lining with the Technogips Pro moisture resistant plasterboard type H2. For this purpose we first cut holes for the fasteners with a drywall saw and then we fix the board to the vertical profiles on the wall with self-drilling screw TB 3.5 x 25.
