Duo-tec & Promax 28 vs 33

[BrianB]

could someone please confirm that the 28he is identical to the 33 with the exception of a different microchip on the pcb hence different outputs

all other main componants appear to be the identical

33 has a bigger burner and plate heat exchanger

 

[BrianB]

are you sure as the parts number for both is the same in all merchants

 

[Billy Bob Bob]
