UltraGas® Featuring our patented aluFer® heat exchanger Hoval aluFer® technology The internationally patented aluFer® tube is a Hoval innovation in advanced heat transfer technology. It is constructed from an inner aluminium finned surface, heat shrunk within an outer stainless steel tube. The exceptional efficiency of the heat transfer is attributed to the following factors: • High heat conductivity of aluminium being ten times greater than that of steel A ten times larger heat exchange surface due to the internal finned surface of the aluminium tube Optimised turbulence and heat exchange...

Large water capacity – energy efficiency Double or  Multiple boilers – maximum output The large water capacity of the boiler allows for continuous operation of the burner and fewer starts. This significantly reduces gas consumption. If a very high output is required, the UltraGas® can be used in a double or multiple boiler configuration. The TopTronic®T regulator allows up to five boilers to be ­entrally controlled in a c cascade. Large water capacity – simple integration Space-saving design The UltraGas® does not require a minimum amount of circulating water1, minimum boiler return, or...
