Ruud Gas Storage Hot Water heaters are built tough and have a solid reputation behind them. The Ruud cylinder range has a variety of features built in to increase efficiency and ensure a quiet operation. All Ruud cylinders have a surface which features an exclusive glass like lining to resist corrosive attacks of hot water chemicals.
The Ruud 190L Direct Vent storage water heater allows the placement of gas water heating where traditionally only electric has been used. No room air is used, as all air for combustion comes from outside the dwelling, therefore no internal ventilation is required. This is a great option for garages. This saves money on installation costs and the ongoing use of the cylinder.
