My parents had a new boiler last winter, and of course they've fitted a sealed system. That means Dad has to call out a pro every time he wants to bleed a rad to repressurize the system - abit expensive, but he's wary of doing it himself.
My boiler is about ready for replacement, but I want to keep my lovely, simple (I understand and can nurse it) open vented system. Do HE boilers have to be sealed systems, or can I just get a CORGI man (or woman) in to replace the boiler, without ripping out everything else?
