its not a combi boiler

hi-spec plumbing, January 2007

as far as I recall the potterton Netaheat is a conventional boiler ... check in your loft to see if you have an expansion tank as well as the domestic water storage tank.If you do have the small tank in your loft, there is no pressurising involved, just fill and bleed from all air vents.
