Buffer Tank KOSPEL SV-200 unenameled insulated 200 L

The KOSPEL SV-200 unenameled insulated 200 L buffer tank is designed to store and stabilize heated water from boilers, heat pumps or solar thermal systems. With an approximate 200 litre capacity and factory-applied thermal insulation, the tank supports hydraulic separation between heat sources and consumers, reduces short-cycling of generators and evens out temperature fluctuations in central heating circuits. The unenameled internal surface is suitable when external corrosion protection or specific system water treatment is planned.

Advantages

The SV-200 buffer tank combines passive thermal storage with compact dimensions and pre-fitted insulation for lower heat loss. By providing hydraulic decoupling and thermal inertia it helps to improve system efficiency, reduce on/off cycles of boilers or heat pumps, and stabilise supply temperatures to radiators or underfloor heating. The simple construction without internal enamel coating allows flexibility for external corrosion protection measures and particular water chemistries.

Suitable for

• Central heating systems with boilers, pellet or gas heaters
• Heat pump installations requiring thermal buffering
• Solar thermal systems storing intermittent collector heat
• Systems needing hydraulic separation to prevent short-cycling

Key specifications

• Approximate usable volume: 200 litres
• Internal finish: unenameled (bare steel) suitable for external protection
• Thermal insulation: factory-applied insulation jacket to reduce standby heat loss
• Function: hydraulic separation and thermal accumulation for heating circuits
• Application: compatible with boilers, heat pumps and solar thermal collectors

How to use

Install the buffer tank in accordance with local regulations and the system designer’s layout, ensuring correct pipe connections for supply, return and any auxiliary circuits. Connect pumps and safety devices as required, and provide an appropriate external corrosion protection or water treatment strategy if system water is aggressive or if long-term durability is required. Fill and vent the tank before commissioning, and follow the commissioning sequence recommended for the heat source so that the tank contributes to hydraulic separation and temperature smoothing as intended.

Usage recommendations

For reliable operation, combine the buffer tank with properly sized pumps, check valves and safety equipment. Periodic inspection of insulation condition and system water quality is advised. When used with un-treated water or aggressive fluids, apply suitable external protection or coatings and follow local standards for corrosion prevention.
