2 BOILER
2.1 Operation and components
The Avanta Plus is a high-efficiency system or combi boiler for
domestic space heating and hot water production.
The combi boiler provides space heating and contains a plate
heat exchanger, three way diverting valve and additional com-
ponents to supply instant DHW direct from the boiler on a pri-
ority basis without the need for storage
The system boiler provides space heating and can be used in
conjunction with a cylinder/calorifier and other external controls
to provide DHW indirectly
Both models have helical stainless steel heat exchanger’s c/w
a premix burner ensuring high heat transfer efficiency with
flue gases being discharged via the concentric flue system.
Condensation which forms during the combustion process is
discharged via the siphon on the underside of the boiler.
An intelligent advanced boiler control unit (‘
abc
®
’) provides all
the necessary safety and operational safeguards using internal
and external sensors etc to ensure that the boiler operates
reliably with maximum efficiency
