Loading…Boiler safety group
A boiler safety group is used as a safety component in heating systems, boilers, buffer tanks and hydronic heating circuits. The group supports safe pressure protection and helps protect installations against unwanted overpressure.
At Hewa, you will find boiler safety groups for service work, installation, renovation and technical replacement. When selecting the right version, always check connection size, system pressure, opening pressure, installation position and the technical requirements of the heat generator or boiler.

Selecting a boiler safety group
A boiler safety group is designed to help a heating system or boiler installation operate safely when pressure builds up. Depending on the version, a boiler safety group may consist of several safety and control components, such as a pressure relief device, pressure gauge or air venting option. This makes the group an important component for installation, service and technical replacement.
When selecting a boiler safety group, connection size, maximum system pressure, opening pressure, temperature suitability and installation position are important. The group must match the heat generator, pipework and other components within the installation.
Important when choosing boiler safety groups
- Check the correct connection size for the pipework and heat generator
- Match the opening pressure to the permitted system pressure of the installation
- Check suitability for heating water and the correct temperature class
- Check whether the group is suitable for the boiler, water heater, buffer tank or heat pump installation
- Ensure a technically correct installation position and good accessibility for inspection
- Allow for safe discharge in case of overpressure or air venting
- Have installation, inspection and replacement carried out by a qualified installer
Safety and pressure control in the installation
A boiler safety group works together with other components in the heating system. For a reliable installation, pressure build-up, expansion, filling and air removal must be properly coordinated. Also review related components such as pressure relief valves for pressure protection, expansion vessels for pressure absorption and filling hoses for controlled system filling.
An incorrectly selected or incorrectly installed safety group can lead to leakage, pressure issues, faults or unnecessary stress on components. Always check the technical data of the existing installation and compare it with the specifications of the new boiler safety group.
Frequently asked questions about boiler safety groups
What is a boiler safety group used for?
A boiler safety group is used to support a heating system or boiler installation with pressure protection, control and safe operation. The exact function depends on the version and the components included.
What should I check when choosing a boiler safety group?
Check connection size, opening pressure, maximum system pressure, temperature suitability, installation position and compatibility with the heat generator or boiler. These details must match the technical requirements of the installation.
Is a boiler safety group the same as a pressure relief valve?
No, a pressure relief valve is usually one specific safety component. A boiler safety group may consist of several parts and is used as a complete safety group within the installation.
Can a boiler safety group be used with a heat pump?
This depends on the hydraulic layout and the technical specifications of the group. Always check whether the version is suitable for the pressure, temperature and hydraulic application of the heat pump system.
Who should install a boiler safety group?
For safe operation, a boiler safety group must be positioned and connected correctly. Installation and replacement should preferably be carried out by a qualified installer.
