Demudding is an important process for ensuring the longevity and performance of your heating system. Over time, impurities and limescale deposits can build up in pipes and radiators, reducing the flow of hot water and leading to a loss of energy efficiency. The aim of descaling is to remove these impurities and deposits to improve the performance of the installation and avoid potential problems such as leaks, blockages and breakdowns. Prices start from €450.

There are several methods of removing the deposits from a central heating system, but the most common involves manually draining the pipes and radiators, using specific chemicals to dissolve the deposits. However, it is important to choose the most appropriate method depending on the nature of the heating network and the deposits that have built up. In all cases, it is advisable to start by draining the entire system.

Steps in demudding


The heating engineer contacts you to find out about your heating circuit installation.


The Pro will inject one or more cleaning products depending on the condition of the installation. He then uses a cleaning machine that uses a targeted and powerful flow of fresh water (up to 99l/min) to quickly and completely remove sludge, limescale and debris from existing and contaminated domestic central heating systems.


When cleaning is complete, the Pro will rinse the system, heating it one step at a time. It refills the system with clean fresh water.


Once the circuit has been rinsed, the Pro restarts the entire system by injecting a product to protect your system. He accompanies you to go round the radiators and bleed them. You'll see the difference straight away.


A detailed report with photos will be sent to you by the heating plumber after the job.

Advantages of demudding

When carried out correctly, demudding can have a significant impact on the performance of the heating system. Firstly, it allows hot water to circulate more smoothly, resulting in better heat distribution in the radiator. What's more, by eliminating limescale deposits, demudding reduces the risk of blockages and leaks, which can lead to costly breakdowns and unnecessary repairs. Finally, by improving the energy efficiency of the heating system, demudding can reduce energy consumption and the associated energy costs.

It's important to have your heating system checked and demudded regularly, usually once a year. This can be done by a certified professional or a qualified technician. When demudding, it is important to ensure that all parts of the heating system are cleaned, including pipes, drains, radiators and circulators, to ensure optimum performance.

Demudding is an important step in the maintenance of your heating system. It cleans heating systems such as underfloor heating, boilers and pipes to remove sludge and other build-up that can damage the water circuit. If you notice a drop in the performance of your air-conditioning or hot-water production system, it may be time to call in a plumber-heating engineer to carry out a purge and drain. Demudding may also be necessary if you are replacing a boiler or have recurring problems with leaky taps. Call in a professional to remove the deposits and get your heating system up and running again.
