Two independently operating smooth-tube heat exchangers allow the hydraulic integration of two heat sources, for example a solar thermal system and a boiler, a heat pump, or another suitable heat generator.\u003c\/p\u003e \u003cp\u003eThe tank design is suitable for bivalent hot water systems where renewable heat is utilized and, if needed, supplemented by a second heat source. The ErP storage volume is 278 liters.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e \u003cp\u003eThe tank body is made of steel S235JR and is enameled on the domestic water side. Two magnesium anodes supplement the corrosion protection. The two smooth-tube heat exchangers are made of steel P235GH and operate hydraulically independently of each other.\u003c\/p\u003e \u003cp\u003eThe lower heat exchanger has a transfer surface of 1.2 m² and achieves a continuous output of 39 kW under defined test conditions. The upper heat exchanger has 0.9 m² of transfer surface and a continuous output of 31 kW. The actually transferable output depends on the temperatures, flow rates, and operating conditions of the respective system.\u003c\/p\u003e \u003cp\u003eThe equipment includes an inspection opening, a circulation connection, several thermometer pockets for temperature sensors, a thermometer connection, and connections for an optional electric heating element. The permanently integrated 50 mm PUR rigid foam insulation reduces heat loss to the installation room. The tank achieves energy efficiency class B with a standby heat loss of 51 W.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Benefits\u003c\/h2\u003e \u003cp\u003eThe separate heat exchangers create a flexible basis for different system concepts. The lower heat exchanger can, for example, transfer solar heat into the tank, while the upper heat exchanger handles reheating via another heat source.\u003c\/p\u003e \u003cp\u003eThe inspection opening facilitates inspection, cleaning, and maintenance of the tank interior. Multiple sensor positions support temperature detection and control adapted to the system concept.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eSystem Integration \u0026amp; Compatibility\u003c\/h2\u003e \u003cp\u003eThe Sunex FISH S2 300 X is designed for closed domestic hot water systems with two separately connected heat sources. In addition to solar thermal, suitable boilers, wood heating systems, or heat pumps can be integrated. For heat pump systems, the heat exchanger surface, heat transfer capacity, flow rate, and required hot water temperature must match the heat pump used.\u003c\/p\u003e \u003cp\u003eConnections with 1 1\/2 inches are available for electric auxiliary heating. The electric heating element, safety group, domestic hot water expansion vessel, pumps, controls, and other system components must be selected according to the respective system design.\u003c\/p\u003e \u003c\/div\u003e \u003cstyle\u003e .product-th{margin-top:2rem}.product-th h2{margin:0 0 1rem}.product-th__table{width:100%;border-collapse:separate;border-spacing:0}.product-th__table td{padding:.95rem 1rem;vertical-align:top}.product-th__label{font-weight:700;width:38%;color:#213670}.product-th__value{color:#1f2937}.product-th__table tr:nth-child(odd) td{background:#f4f7fb}.product-th__table tr:nth-child(even) td{background:#fafbfd} \u003c\/style\u003e \u003cdiv class=\"product-th\"\u003e \u003ch2\u003eTechnical Data at a Glance\u003c\/h2\u003e \u003ctable class=\"product-th__table\"\u003e \u003ctbody\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eStorage Type\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003eHot water storage tank with two heat exchangers\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eNominal Capacity\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e300 liters\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eSuitable for drinking water\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eStorage tank material\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003eSteel S235JR, enameled\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eNumber of heat exchangers\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eInsulation\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e50 mm rigid polyurethane foam\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eMaximum storage temperature\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e95 °C\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eMaximum operating pressure of the storage tank\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e10 bar\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eHeight\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e1,461 mm\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eWidth and depth\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e657 mm\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eEmpty weight\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e123 kg\u003c\/td\u003e\n\u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eInstallation\u003c\/h2\u003e \u003cp\u003eThe storage tank must be installed exclusively upright in a dry and frost-free room on a level, permanently load-bearing surface.
