A system boiler usually has additional components - typically pump, expansion vessel, filling loop, etc. - ready installed inside its casing. A non-system boiler doesn't - and these components have to be supplied and installed externally. [I assume 'primary' refers to an ordinary, non-system boiler - but am not too familiar with the term]. A system boiler requires less effort to install - but the integrated components are often proprietary, and more expensive to replace than the generic components used in a conventional setup. -- Cheers, Set Square ______ Please reply to newsgroup.
