## Long description

Safety group Vaillant 305827 for closed heating systems is a pressure-relief and safety assembly designed for boilers and storage tanks with capacities above 200 liters. Rated for a maximum operating pressure of 10 bar, this safety group monitors system pressure and provides controlled discharge in the event of overpressure to protect piping, valves and heat-generation equipment. The unit is intended for installation on larger residential or light-commercial closed heating systems that require a 10 bar safety device.
Advantages
The Vaillant 10 bar safety group combines overpressure protection and reliable discharge performance in a compact assembly suitable for closed-loop heating. Its design provides consistent activation at the rated pressure, helping to prevent damage from excess pressure. Constructed for compatibility with larger boilers and tanks, the unit supports safe system operation and reduces the risk of unscheduled shutdowns due to pressure-related faults.

Key specifications

How to use
Install the safety group on the designated pressure take-off or safety port of the boiler or storage vessel following the boiler manufacturer's installation instructions and local regulations. Ensure correct orientation and secure connections with appropriate fittings and sealing materials rated for the system pressure. After installation, fill and vent the heating system to remove trapped air, then verify the safety group's operation by observing system pressure at normal operating conditions and confirming no unintended leakage occurs. Any maintenance or replacement should be carried out when the system is depressurised and cooled.
