Hygienic buffer tank HSK-OEKO Legionella-safe DHW preparation ... Heat buffer tank with integrated stainless steel corrugated tube for legionella safe preparation of DHW, with well dimensioned heat exchangers out of circular tube, improved layering of the heating return line in the stratification pipe. Perfectly suitable for single and two family houses. Available standard sizes 700 und 1000 litres, each type with one stainless steel heat exchanger and two solar heat exchangers. Legionella-safe and economical preparation of DHW with stainless steel heat exchanger The cost efficient „HSK OEKO“ with integrated stainless steel corrugated hose for the preparation of DHW, is perfectly suitable for the economical application in single and two family houses. It convinces with its versatility just as much as the exclusive version „HSK-SLS“. Almost all heat generators, e.g. solar panels, oil/gas boilers, wood log boilers, electric heating elements, pellet boiler, etc. as well as the energy consumers (hot water and heating) can be operated by one single tank. Even though the buffer system is that multifunctional the effort of controlling the tank is kept very simple because all connections are constructed in such a way that each heat generator and consumer connected to the tank can operate absolutely independent, according to requirement and availability. The DHW is freshly heated up by the corrugated stainless steel hose coiled in the tank. The advantages of a boiler and a continuous flow heater are cleverly combined in this system. An extremely fast heat transmittance from solar energy to hot water is achieved by an additional plain tube heat exchanger in the upper part of the tank. The corrugated design precludes the calcification of the DHW. The heat exchanger insignificantly expands itself during heating up and cooling and thus limescale deposits are avoided as far as possible. During the removal the corrugated design causes velocity. These turbulences enable the washing out of the limescale particles together with the hot water. When necessary the stainless steel DHW heat exchanger could be rinsed with a suitable descaler. As you can see the cost efficient version „HSK-ÖKO“ with its outstanding quality sticks out of the wide range of conventional HSK tanks. Take advantage of these benefits connections arranged in 90° angle, possible installation in the corner various connection possibilities perfect heat stratification due to the stratification pipe insulation thickness 100 mm, available either as fleece ISO-B1 or flexible foam insulation high quality steel S235JR large solar heat exchangers legionella-safe DHW preparation stainless steel corrugated hose 1.4404 with DVGW authorization high hot water output installation of an electric heating element possible
