TECHNICAL DESCRIPTION
The water heater is designed for heating water in bivalent systems, as well as for its accumulation and storage for DHW. The lower heat exchanger is intended for connection to low-temperature heat sources (e.g., solar collectors, heat pumps). The upper heat exchanger is designed for connection to high-temperature sources (primarily used for additional heating). The tank’s design includes a flanged inspection hatch with a cover, intended for periodic service maintenance of the tank. Above the lower heat exchanger, a fitting is provided for installing a tubular electric heater.
MATERIAL
The tank is made of AISI 316L (DIN 1.4404) stainless steel, meeting the highest hygienic requirements.
HEAT EXCHANGERS
The heat exchangers are made of AISI 304L (DIN 1.4307) stainless steel.
