SUNEX FISH S8 200 X hot water tank for domestic hot water
The SUNEX FISH S8 200 X is a standing, enamelled hot water tank for storing and providing domestic hot water. The model has a nominal capacity of 200 litres and a declared ErP storage volume of 208 litres.
The series is designed without an integrated heat exchanger and is suitable for correspondingly planned hot water systems with external tank loading or electric auxiliary heating. Thanks to its cylindrical standing design, the tank requires a footprint of approximately 607 × 607 millimetres.
Technology and equipment
The tank container is made of steel S235JR and is provided with an enamel coating on the drinking water side. Two magnesium sacrificial anodes support the corrosion protection of the inner container. The design of the tank is intended for providing domestic hot water and complies with the construction method used for enamelled hot water tanks according to DIN 4753.
A permanently foamed, CFC-free PUR rigid foam insulation with a thickness of 50 millimetres reduces heat loss to the surroundings. The grey PVC outer jacket encloses the insulation and forms a closed, easy-care outer surface. The standby heat loss is 45 watts; the energy efficiency class is stated as B.
The equipment includes an inspection opening with a diameter of 122/179 millimetres, three connection positions for hot water sensors, a connection for a thermometer, a circulation connection, and two connections in G 1 1/2 inch for electric auxiliary heaters or heating elements.
Everyday benefits
The inspection opening allows access to the inner container for inspection, cleaning and maintenance. The different sensor positions facilitate system-appropriate temperature detection at several tank heights.
A separate circulation connection supports the integration of a hot water circulation system. Unused connections can be sealed during professional installation. In addition, there is a connection option for the intended UV-20 disinfection system.
System integration and compatibility
The SUNEX FISH S8 200 X does not have an integrated heat exchanger. The heating of the stored drinking water must therefore be carried out via a suitable external storage charging system or a separately designed electric auxiliary heater.
The hot water and cold water connections are each designed in G 1 inch. A connection in G 3/4 inch is available for a circulation line. Three sensor connections and the thermometer connection each have G 1/2 inch.
The selection and design of the heat generator, charging device, safety group, drinking water expansion vessel, pressure reducer, circulation pump, and temperature control must be coordinated with the hot water demand and the specific system concept.
Technical data at a glance
| Storage tank type | Hot water storage tank |
| Nominal capacity | 200 liters |
| Suitable for drinking water | Yes |
| Storage tank material | Steel S235JR, enameled inside |
| Integrated heat exchangers | 0 |
| Insulation | 50 mm rigid PUR foam with gray PVC jacket |
| Maximum operating temperature | 95 °C |
| Maximum operating pressure | 10 bar |
| Height | 1,306 mm |
| Width | 607 mm |
| Depth | 607 mm |

Mounting
The storage tank must only be installed standing upright on a load-bearing, level and horizontal surface. For transport and installation, in addition to the height of 1,306 millimeters, the diagonal dimension of 1,395 millimeters and the empty weight of 62 kilograms must also be taken into account.
A suitable safety group and a safety valve with an opening pressure of 6 bar must be provided at the cold water connection. No shut-off device that impairs the safety function may be installed between the safety valve and the storage tank. If the supply pressure exceeds 6 bar, a suitable pressure reducer is required.
Before the heat generator or an electric auxiliary heater is put into operation, the storage tank must be completely filled, vented and checked for leaks at all connections.
Notes
For permanently safe operation, the water quality, corrosion protection and the condition of the magnesium anodes must be checked regularly. A pH value of 6.5 to 8.5, an electrical conductivity of at least 200 µS/cm and a chloride content of no more than 150 mg/l are specified.
The magnesium anodes must be inspected at the latest every 18 months and replaced if they show corresponding wear. Shorter maintenance intervals may be required in the case of high water hardness, critical water quality, heavy deposits or intensive use.
At high hot water temperatures, suitable thermostatic anti-scald protection must be provided. Electric auxiliary heaters may only be connected in accordance with their respective instructions and by a qualified electrician.
