Frequently Asked Questions

Q: What sizes does the DN25 Boiler Safety Group come in?

A: This boiler safety group is available in three sizes — 20mm, 25mm, and 32mm — making it compatible with a wide range of residential and light commercial heating systems.

Q: What is the pressure rating of the safety valve included in this group?

A: The included safety valve is rated at 6 bar. The pop-action valve mechanism activates automatically to discharge excess pressure whenever the system pressure exceeds this threshold, helping protect your boiler and piping.

Q: Why is a quick bleeder important in a boiler safety group?

A: The quick bleeder (automatic air vent) removes trapped air from the heating circuit. Air pockets can reduce heating efficiency and cause unusual noises or circulation problems. The integrated quick bleeder handles this automatically, keeping your system running at peak performance.

Q: Is this safety group easy to install?

A: Yes. The DN25 Boiler Safety Group is designed as a self-contained assembly, combining the safety valve, quick bleeder, and pressure gauge in a single compact unit for straightforward installation. However, if you are not experienced with heating system plumbing, we recommend having a qualified technician perform the installation.
