Unvented Water Cylinder Servicing and Maintenance

COMMERCIAL UNVENTED WATER SYSTEM MAINTENANCE AND SERVICING

G3 Unvented System Maintenance

Unvented water systems are high-pressure hot water systems commonly used in commercial environments where reliable and efficient hot water supply is essential. These systems connect directly to the mains water supply, eliminating the need for a cold water storage tank and offering improved flow rates and performance.

Regular servicing is essential to ensure these systems operate safely and efficiently. At UK Property Service, we carry out full inspections, testing, and maintenance in line with G3 Building Regulations, helping you prevent breakdowns, maintain pressure, and stay compliant.

Our servicing includes:

  • Inspection of pressure and temperature relief valves

  • Checking and recharging expansion vessels

  • Testing thermostats, immersion heaters, and safety controls

  • Inspection for leaks, corrosion, or scale build-up

  • Cleaning strainers and checking discharge pipework

  • Servicing by G3-qualified engineers

  • Scheduled visits to minimise operational disruption

  • Full system testing and fault identification

  • Advice on system performance and energy efficiency

  • Certification and service reports for compliance
