  • No pilot light
  • No pilot hood to wear

  • Burner is now high-temp ceramic mesh

The Technology
Viron’s technology has been developed around a unique stainless steel knitted mesh burner which fires downwards through multiple layers of extruded finned tube through which the pool or spa water passes. This unique burner utilises a fan which premixes gas and air for perfect combustion, regardless of the water installation or weather conditions. The heat exchanger absorbs so much heat from the combustion process that the flue gases condensate.
