Ariston Genus 30 Plus 20 BFFI Boiler

   
 
Wall-hung electronic ignition gas combination boiler with an integral 50 litre hot water storage cylinder
30 kW / 102400 Btu/h, Fan flued, Natural Gas

The GENUS 30 PLUS has been designed to supply large quantities of hot water in the shortest time possible. Hot water is always available at the desired temperature thanks to the integral 50 litre stainless steel unvented hot water storage cylinder. The recovery time for hot water is exceptionally fast, even when consumption is high and a number of taps are used at the same time. The GENUS 30 PLUS is wall hunging saving valuable floor space for other appliances.

Guarantee:
2 years (extendible up to 5 years).
