Electronic circuit board with the microprocessor for higher safety and advanced monitoring
Double flame sensors
Clean gas combustion with the help of the air-fuel ratio rod and computerized operation
Commercial grade materials for heavy duty conditions
Primary heat exchanger - some models are made of Copper Alloy HRS35 which gives more strength than the regular type (commonly used) copper
Secondary heat exchanger made of 316L Stainless Steel - condensing models only
Safety features that protect the units from freezing, extremely high temperatures and overheating
There are several models with the tankless technology that are
