An unvented cylinder is a hot water storage system that is pressurized and connected directly to the mains water supply, providing high-pressure hot water throughout the property. Regular service and maintenance of an unvented cylinder are essential for ensuring its efficiency, longevity, and safety.

During an unvented cylinder service, a qualified engineer will inspect the system and its components, checking for any leaks, corrosion, or other signs of wear and tear. The engineer will also test the pressure relief valve, expansion vessel, and thermostat, and make any necessary adjustments or repairs to ensure that the system is working correctly.

If any faults or issues are identified during the service, the engineer will advise on the best course of action, which may involve repairing or replacing faulty components. Regular servicing can help prevent breakdowns, reduce energy bills, and extend the lifespan of the system.

In addition to regular servicing, it is important to have an unvented cylinder repaired promptly if any faults or issues are identified. Common problems with unvented cylinders include leaks, blockages, and failure of components such as thermostats or pressure relief valves. Ignoring these issues can result in more significant problems and even potential safety hazards.

It is important to use a qualified and experienced engineer to carry out any servicing or repairs on an unvented cylinder. This is because unvented cylinders operate at high pressures and temperatures and can be dangerous if not handled correctly. A qualified engineer will have the necessary training and expertise to work safely and effectively on these systems.
