North Leeds Plumbing & Heating – Home Improvement and DIY Advice

There are five steps to fitting a wet underfloor heating system. Firstly you need to fit the manifold, which is supplied pre-assembled, to the wall.

Step two is insulating the floor surface and securing fixing rails to the floor. There are various options when it comes to insulation, but make sure that you get a good brand that is waterproof. The supplier that you buy your underfloor heating system from should be able to recommend a suitable product and this can be fixed to the floor with normal tile adhesive.

Once this is dry you need to consider the fixing rails, which need to be laid out in parallel lines along the floor to give the brackets that sit over the pipe work a fixing point. Remember, the pipe work will snake around the floor and rest against these fixing rails, so you must ensure they are suitable for the amount of pipe work you are going to use. There are various online sites that will give you pointers on how to set out your fixing rails, but you do need to make sure they are well fitted and that the ends are secured to the walls. They should also be fixed to the insulation with adhesive.

Make sure that the adhesive fixing all these elements dries out completely before you move onto the next stage or you could have unwanted movement, which could be detrimental to the efficiency of the completed system.
