A well-maintained central heating network guarantees optimum thermal comfort and avoids unnecessary energy losses. However, leaks can appear over time, causing a drop in pressure, over-consumption of energy and damage to property. To avoid these problems, it’s essential to adopt good maintenance and prevention practices. <\/p>\n\n
Over time, pipes and fittings in the central heating circuit can corrode, especially if the water contains impurities or if the system is poorly balanced. Corrosion weakens pipes and can lead to cracks. <\/p>\n\n
A loose or worn gasket can be the cause of a leak. Similarly, ill-fitting fittings can allow water to leak out gradually, leading to a drop in pressure in the circuit. <\/p>\n\n
Temperature variations in a heating system cause pipes to expand and contract. In the long term, this can lead to micro-cracks or deformations, encouraging leaks. <\/p>\n\n
Lack of purging, sludge build-up or poor system balance can accelerate component wear and increase the risk of leaks.<\/p>\n\n
A heating circuit must operate at a stable pressure, generally between 1 and 2 bar. If the pressure is too low or too high, there may be a problem. Regularly checking your boiler’s pressure gauge can help you anticipate any possible anomalies. <\/p>\n\n
Air build-up in the system can create pressure imbalances and encourage leaks. We recommend bleeding radiators at least once a year, before the heating season. <\/p>\n\n
Periodic checks of pipe, valve and radiator connections can detect the first signs of wear before a leak occurs.<\/p>\n\n
Adding an anti-corrosion product to the circuit water protects the pipes and extends the life of the system.<\/p>\n\n
A sludge-filled circuit reduces heating efficiency and accelerates component wear. Regular de-sludging every 5 to 7 years preserves the integrity of the pipes and limits the risk of leaks. <\/p>\n\n
An expansion vessel absorbs variations in water volume caused by temperature. If it’s undersized or defective, pressure can become unstable, leading to leaks. <\/p>\n\n
If a leak is detected, it’s essential to react quickly to prevent the problem from worsening. Shut off the water supply to the heating system and contact a professional for an accurate diagnosis and appropriate repair. <\/p>\n\n
