System boiler on a vented system

[andylester]

Hi,

Can I fit a "system" boiler on a vented system?

I have a copper thermal store cylinder which is 210 Ltrs of water treated with inhibitor and is directly connected to the boiler and nothing else. The cylinder has a header tank mounted directly above it to ensure it is constantly topped up and is 3M above the boiler inlet creating 0.3bar. This is working fine and i would rather not replace it, and cannot make it pressurised.

I have bought and installed (but not tuned on) a Biasi Advanced Plus 30kW system boiler with a minimum working pressure of 0.3bar.

I am concerned that I might have an issue with a boiler designed for a sealed pressurised system working with such a vented system, but as the pressure should be within the specified range I do not know what else could cause problems. Biasi technical support are no use. The underfloor heating company cannot see a problem so suggest I try it and see.

Is there a reason why this would not work?
Has anyone done this and seen any issues?

Regards,
Andy

Its quite loud and clear that youre not trained, competent or qualified if you have to ask this?!

as such you're not going to get any advice.

get a qualified gas engineer in before you kill yourself, family, cat, dog or neighbors.
