What it is

The Biasi BI1002110 is an expansion vessel for Biasi gas boilers. It absorbs the expansion of water as the heating system warms up, limiting the pressure rise within the sealed system. The vessel is listed for a range of Biasi 24S, 28S, Prisma, Garda, RIVA and Savio GAIA appliances.

Signs this part needs replacing

  • Boiler pressure rises quickly when the heating is running
  • Pressure relief valve discharges water during heating cycles
  • System pressure drops repeatedly and needs frequent topping up
  • Water or air escaping from the vessel's valve
  • Boiler locks out on low pressure
