TECHNICAL DESCRIPTION

Due to the increased heat exchanger area, the water heater is ideally suited for operation with a heat pump. The enlarged heat exchanger area also allows connection to high-power sources, ensuring high DHW output with relatively small tank volumes. The tank’s design includes a flanged inspection hatch with a cover, intended for periodic service maintenance of the tank. Above the heat exchanger, a fitting is provided for installing an electric heat element.

MATERIAL

The tank is made of AISI 316L (DIN 1.4404) stainless steel, meeting the highest hygienic requirements.

HEAT EXCHANGER

The heat exchangers is made of AISI 304L (DIN 1.4307) stainless steel.

THERMAL INSULATION

PL/ABS	50 mm polyester insulation in an ABS plastic casing with plastic latches
PS/ABS	High-efficiency rigid graphite polystyrene insulation in an ABS plastic casing. Premium-class insulation – complies with all requirements of the ErP 2009/125/EC Directive
