It's the size of the pipes (Flow and Return) on a Greenstar FS 30CDi.

Best way is no vents or feed pipes on oil or gas.
Sealed system if it is at all possible.

fair enough you do realize you cant install a boiler unless your gas safe?

 

[stevetheplumber]

plus one for sealing the system, that boiler is available as a system boiler im sure
any reason for this choice?

 

[gassafe]

I'd guess it's an old house, pipes underf floor & minimising the risk of creating leaks?

The tank fed should be okay as longs it's all cleansed correctly, plenty of inhibitor & check there's no pumping over etc into the tank!

Non of them ! all your connections and pump look as though they are on return pipe

 

[Sparkgap]

Go with 1. Ideally, you want the cold feed to dip under and connect into the bottom of the pipe to stop possible gravitation into the tank.
