Frequently Asked Questions - SVW-400.1 KOSPEL

What is the difference between SV and SVW models?

The SVW model is equipped with an integrated coil for connecting an additional heat source (e.g., solar panels). The SV model does not have one.

Can this tank be used for domestic hot water?

No, the SVW-400.1 buffer tank is designed for heating water storage (closed circuit). It does not produce domestic hot water directly.

What is the maximum operating pressure?

The maximum pressure in the tank is 0.3 MPa (3 bar) and in the coil 1 MPa (10 bar). Do not exceed these values.

How to install the tank correctly?

Install the tank in a vertical position on a flat and stable surface. Ensure sufficient clearance to access connections. Installation must be done by a professional.

What maximum temperature is allowed?

The nominal temperature must not exceed 80°C for this 400-liter model. Excessive temperature may damage the unit.

Must a safety valve be installed?

Yes, a safety valve is mandatory on the heating circuit. It must comply with current standards and be checked regularly.

What maintenance is required?

Visually check the tightness of connections and proper operation of the safety valve at least once a year. Bleed air if necessary.

What to do in case of a leak?

Immediately close the shut-off valves of the heating circuit and contact technical support. Do not attempt to repair yourself.

Can this tank be used with a heat pump?

Yes, the buffer tank is compatible with heat pumps and boilers. It serves as energy storage and hydraulic separator.

How to dispose of the tank at end of life?

Do not dispose of the appliance with household waste. Take it to a recycling center or contact your municipal service for proper recycling.

• 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 (400l and 500l). In the buffer tank (200l; 300l; 800l; 1000l) should not exceed 95^ C.

Application

The buffer tanks SV and SVW are devices designed for storing heating water (and/or cooling for 200; 300 liters) in collaboration with heating boilers and heat pumps. Additionally, they serve as a manifold (coupling), hydraulic separator, and heating circuit from the boiler room. The SVW tank has a built-in coil for connecting other heat sources. The buffer tank is made of black steel sheet, raw on the inside and protected on the outside with anti-corrosion paint. The SV and SVW tanks have thermal insulation made depending on the capacity from: 200, 300 liters - PUR foam; 400, 500 liters - styrofoam; 800-1000 liters polyester fleece. The large number of connections allows for various connection options.

The maximum working pressure of buffer tank:

- 0,3 MPa - Buffer tanks of 200 - 1000 litres

The maximum working pressure in the coil:

- 1 MPa - Buffer tanks of 200 - 1000 litres
