1985: Thermomax - burner (Gas premix burner)Hoval sign with Ruhrgas (Germany)a secret agreement over the special burner
1989: The first UltraGas®
At 3th April 1989 the UltraGas name was mentioned the firsttime !Boiler design: Combustion chamber made of stainless steeland a seperate heat exchanger made of aluminiumBurner: Premix burner (System Ruhrgas)
November 1989: First registration for UG-C (20, 30)

1990: First redesign in Februar 1990
The UltraGas® serie increase in the middleof 1990:With the type UGC (40) and UGC (12)
1992: Further increase o theUltraGas® serieWith the type UGC (50) and UGC (60)

1993: Development of the newheat exchanger (aluFer)
Our target was to develope a heat exchangerwith a big water content and no aluminium on thewater side.
The result was the aluFer – tube !
1994: The first UltraGas® mit aluFer tubeswas built.In February 1994 the firts boiler with aluFer – tubes wasbuilt !
