How frequently should unvented hot water systems be serviced for optimal performance?

Unvented hot water systems should be serviced annually to ensure optimal performance and safety. Regular servicing is essential because these systems operate at mains pressure and are equipped with safety devices, such as temperature and pressure relief valves. Annual maintenance allows for the inspection and testing of these components, ensuring they function correctly and reduce the risk of failure or accidents.

Additionally, servicing helps identify potential issues before they become significant problems, which can lead to costly repairs or compromised system efficiency. By adhering to an annual service schedule, homeowners and maintenance professionals can maintain the reliability and safety of unvented hot water systems, thereby extending their lifespan and improving overall performance. Regular checks also help ensure compliance with safety regulations and manufacturer guidelines.
