Installing and repairing expansion vessels

Expansion vessels are vital components in sealed central heating systems and unvented hot water cylinders, designed to absorb the expansion of water as it heats up. Without a correctly functioning expansion vessel, pressure can build excessively, leading to system damage, leaks, and even safety risks. Common signs of a faulty vessel include frequent boiler pressure drops, recurring boiler fault codes, or constant discharge from the pressure relief valve. Our certified plumbers specialize in the expert installation and efficient repair of expansion vessels, ensuring the safety and optimal performance of your heating and hot water systems.

Our installation service involves correctly sizing and securely fitting the appropriate expansion vessel for your system (heating or hot water), ensuring proper connection to the pipework and adherence to all safety regulations. For repairs and maintenance, we diagnose issues such as insufficient air charge, internal diaphragm failure, or leaks. We carry out tasks like re-pressurizing the vessel, repairing connections, or replacing the unit entirely if necessary. By maintaining or installing a properly functioning expansion vessel, we help prevent costly system damage, extend the lifespan of your boiler or cylinder, and ensure your heating and hot water run efficiently and safely without constant pressure issues.
