It serves to buffer system water and supports a more even hydraulic integration between the heat generator and the heating circuit.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e \u003cp\u003eThe tank is designed as a buffer tank without an integrated heat exchanger. The vessel is made of S235JR, is automatically welded, and has a gray outer jacket. The hydraulic connections are designed as G 1 1\/2\u0026quot; female threads, and the sensor connections as G 1\/2\u0026quot; female threads.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Benefits\u003c\/h2\u003e \u003cp\u003eWith 289 liters of capacity, the tank is suitable for compact to medium-sized heating systems where a manageable buffer volume is required. The connection arrangement allows flexible integration of the heat source, heating circuit, and temperature sensing. The 50 mm thick polyurethane foam insulation with PVC film layer reduces heat losses and protects the tank during regular system operation.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eSystem Integration \u0026amp; Compatibility\u003c\/h2\u003e \u003cp\u003eThe Sunex FISH S4 300 X can be used in systems with solid fuel boilers, oil and gas heating, heat pumps, or electric boilers. Solar support is not provided via an integrated heat exchanger in this tank series, but must be planned through suitable system hydraulics or an additional heat exchanger in the system. For use with chilled water from 7 to 12 °C, the connection stubs must additionally be insulated against condensation and heat absorption.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"product-th\"\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 \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\"\u003eManufacturer\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003eSUNEX S.A.\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eModel\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003eFISH S4 300 X\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eStorage type\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003eBuffer tank without integrated heat exchanger\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eStorage volume\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e289 l\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eEnergy efficiency class\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003eB\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eStandby heat loss\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e50 W\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eMax. operating 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\"\u003eMax. operating pressure\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e3 bar\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eTest pressure\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e4.5 bar\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 polyurethane foam with PVC foil layer\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\"\u003eS235JR\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eDiameter with insulation\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\"\u003eDiameter without insulation\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e550 mm\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eHeight \/ Diagonal\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e1462 \/ 1557 mm\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eHydraulic connections\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003eG 1 1\/2\u0026quot; female thread\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eSensor connections\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003eG 1\/2\u0026quot; female thread\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eVentilation\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003eG 1 1\/2\u0026quot; female thread\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd class=\"product-th__label\"\u003eWeight\u003c\/td\u003e\n\u003ctd class=\"product-th__value\"\u003e60 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 vertically on a level, load-bearing surface.
