Your boiler is not energy efficient A system boiler

Your boiler is not energy efficient. A system boiler still has a hot water cylinder, but the feed and expansion tank (usually in the loft) is replaced by an expansion vessel in the boiler this also typically contains the circulation pump and may house some of the valves. Space saving is a real perk of this boiler system rather than requiring room for large water.
