THE PROBLEM

Once upon a time there was underfloor heating...
First of all, it is important to understand that as soon as water enters the system, the corrosion process begins and iron oxides (sludge) start to form. After several years, this sludge accumulates and causes failures within your heating network. Furthermore, systems that have been installed since the 1970s are generally made of plastic (PEX: cross-linked polyethylene) whose stabilisers evaporate over time, weakening the watertightness of the system.

Result :

clogging that can cause the heating to decrease in certain areas, because a weakened system of coils can result in perforations.

The problem
If you have the unpleasant feeling that your underfloor heating is not working to its full capacity or that certain areas of your home are warm and others are persistently cold, especially if your underfloor heating was fitted more than 20 years ago... there is no doubt that your network is clogged.

A clogged installation ?

This means that a “metaphorical” sludge has formed, so-called because it has the appearance and consistency of sludge but is in fact composed of ferrous oxides.

What is the solution ?

Many people's initial response would be to increase the system's power. However, this is risky for your pipes because it causes faster clogging. Furthermore, this substantially increases your heating-related consumption.
