The BXS water heater range is distinguished by the square-shape design, making for particularly easy installation. Benefits: High quality materials. Heat exchanger with wide exchange surface. Produces hot water from the electric element, that Is fitted with an adjustable safety thermostat. Relief / non-return vale that allows discharging of the water heater in case of disuse. The heat exchanger used for Quick ôNautic Boilersö is made up of a tube in 316 stainless steel which, thanks to its special coiled shape reduces its actual length of more than 3 metres. The heat exchange capacity is notably higher than that achieved from other manufacturers. The tank is made of 1.5 mm gauge 316 AISI stainless steel welded with Argon shielding gas and hence highly resistant to corrosive agents. The electrical heating element is made of incoloy steel. The thermal insulation is high density polyurethane foam injected between the cover and tank giving excellent heat retention properties
