Pipework and insulation made of elastomeric foams or polyethylene foams can help to reduce certain health risks that are associated with heating and plumbing. Insulation is one of the most important things to have when it comes to reducing the rate of bacterial growth inside your domestic water supply pipes.

The Legionella bacteria lives in temperatures between 25c and 60c, which can be encountered in both hot and cold water pipes. This can cause symptoms similar to that of pneumonia when inhaled in small doses.

This is why appropriate piping has to take place in order for the hot water to fall below a certain degree and the cold water to rise above. These are the safe water supply temperatures defined within and by the EN 806-2.

You also have to take into consideration the energy saving elements, environmental circumstances such as humidity, ambient temperatures and pipe temperatures when having the piping installed – in terms of thickness and durability. Regardless of this, the insulation has to be resistant to moisture ingress in order to last longer.

The advantages of FEF and PEF insulation come into play here as using both of these pipework mainframes with a featured built in water vapour barrier will prevent any condensation from forming – either on the pipe or within the pipe itself. This closed cell insulation saves energy as well as protecting the pipe against water ingress.

George Eleftheriadis – Chairman of the European Association CEFEP states that the, “FEF or PEF thermal insulation can reduce temperature variations and so support the quality and purity of your drinking water.”

Therefore, once your proper piping is in place, there are no risks of digesting Legionella and it’s safer for you and your family. Please make sure your pipes are clean and in working order to avoid any fluctuations in the future.
