Frequently Asked Questions - SVW-300.1 KOSPEL

What is the maximum operating pressure of the SVW-300.1 buffer tank?

The maximum operating pressure of the storage tank is 0.6 MPa (6 bar) for the 300-liter model. The heating coil can withstand up to 1 MPa (10 bar).

Can the SVW-300.1 be used with a heat pump?

Yes, the buffer tank is suitable for co-operation with boilers and heat pumps. It can also function as a hydraulic separator or divider.

What are the dimensions of the Kospel SVW-300.1?

Exact dimensions are specified in the manual. The tank has a vertical design and weighs approximately 101 kg empty.

Is the SVW-300.1 buffer tank insulated?

The tank is available in both insulated and non-insulated versions. Check the specific model variant for your unit.

What is the purpose of the heating coil in the SVW-300.1?

The heating coil is designed for connection to a solar collector system. It allows the stored water to be heated using solar energy, with a coil capacity of 9.1 dm³ and a maximum power output of 45 kW (at 80/10/45°C, flow 2.5 m³/h).

How should the SVW-300.1 be installed?

The tank must be installed vertically using the screw feet. All hydraulic work and initial start-up should be performed by a qualified installer. Ensure the room temperature never drops below 0°C to prevent freezing.

What maintenance is required for the buffer tank?

Regularly check for water leaks and test the safety valve according to the valve manufacturer's instructions. If a leak is detected, close the shut-off valves and contact a service technician.

What should I do if the pressure in the tank increases excessively?

SV/SVW CH buffer tank is intended for storing the water. It's suitable for co-operation with boilers and heat pumps. A buffer tank may also perform the following function: divider (hydraulic clutch), hydraulic separator, heating circuit from the boiler room. SVW buffer tank is a tank with built-in heating coil for connection to the solar collector system. A buffer tank is made of black steel sheet. The outer surface of the tank is protected against corrosion by the anticorrosive paint. The inner surface of the tank is a raw steel. They are available in two versions: insulated, non-insulated. A large number of connections provide different connection choices.

The maximum working pressure of buffer tank:

• 0,6 MPa - Buffer tanks of 200 - 500 litres
• 0,3 MPa - Buffer tanks of 800 - 1000 litres

The maximum working pressure in the coil:

• 1 MPa - Buffer tanks of 200 - 500 litres
• 0,6 MPa - Buffer tanks of 800 - 1000 litres

Assembly and operating instructions

• Read and strictly follow this assembly and operating instructions to ensure a long life and reliable buffer tank operation.
• The manufacturer of this buffer tank will not be liable for any damages due to the failure to follow this assembly and operating instructions.
• During all work related to the installation, servicing or maintenance of the device, the principles of health and safety, explosion protection, fire protection and environmental protection must be observed in accordance with the applicable requirements and regulations in the respective country.
• The buffer tank must not be installed in rooms where the temperature may drop below 0^ C.
• The buffer tank installation and initial start-up as well as all hydraulic work must be performed by a qualified installer.
• The heating water must comply with all of the relevant local water quality standard.
• Rated temperature of water in the buffer tank should not exceed 80^ C (300l; 400l and 500l). In the buffer tank (200l; 800l; 1000l) should not exceed 95^ C.
