Open vent boiler on a sealed system

[jaydebruyne]

hello all,

I’m doing a flush today and I’ve noticed they have a Vitodens 100-W WB1B open vented boiler on a sealed system.

Will this cause any issues in terms of normal operation?

Nope fine

 

[jaydebruyne]

Nope fine

It’ll just be a pressure issue right? More than operation?

Nope be fine with pressure

It will be fine. Assuming the system has an expansion vessel and PRV fitted. The only requirement for a heat only boiler on a sealed system is an overheat stat.

Has a flow switch so no / low flow no fire
