Domestic Hot Water Performances
• Burner design ensures a good flame
distribution in the combustion chamber
• Stainless steel provides a long working life
• Electronic ignition
• Gas burner preset in the factory
HM30 G – Natural gas HM30 GP – LPG
Note : The above performances are based on the hot
water being blended at point of use,with a boiler
temperature of 90°C and a domestic cold water
inlet of 10°C.
