What it is
The Oso 115800 is a 6 litre potable expansion vessel, supplied as a single unit. It absorbs the expansion of heated water within a potable (mains-fed) hot water system, limiting the pressure rise as the water volume increases. The vessel is manufactured by Oso and sits within the Advanced Water range of expansion vessels.
