## Summary description

Unenameled buffer tank KOSPEL SV-500.1 with factory insulation, nominal capacity 500 liters. Designed for thermal energy accumulation in heating systems, it provides hydraulic separation, increases system inertia and reduces boiler cycling. Suitable for integration with boilers, heat pumps and solar installations where a non-enamel internal surface is acceptable.

## Long description

Buffer tank KOSPEL SV-500.1 unenameled with insulation, 500 L is a vertical thermal storage vessel with a nominal capacity of 500 liters, intended for accumulation of heat in central heating and renewable energy systems. The inner surface is non-enamelled, and the cylinder comes with factory-installed thermal insulation to reduce heat losses. The tank provides hydraulic separation between heat sources and consumers, increases system thermal inertia and helps to reduce short boiler or heat pump cycling when integrated into heating circuits.
Advantages
The unenameled internal surface allows use in installations where enamel coating is not required or where alternative internal treatments are applied; this can simplify repair and inspection. Factory insulation improves energy efficiency by lowering standby heat loss and maintaining stored water temperature for longer periods. The design supports straightforward hydraulic connection and contributes to smoother operation of boilers, heat pumps and solar thermal systems by stabilizing flow and temperature fluctuations.
Suitable for
 Integration with gas, oil, or solid fuel boilers that accept non-enamelled storage vessels
 Combined systems with heat pumps requiring increased buffer capacity to reduce cycling
 Solar thermal installations used to store collected heat for evening or cloudy-period use
 Hydraulic separation in multi-source heating systems and larger residential or small commercial installations
Key specifications
 Nominal volume: 500 liters
 Inner surface: unenameled (plain metal)
 Construction type: vertical cylindrical buffer tank
 Thermal insulation: factory-installed outer insulation
 Function: thermal energy accumulation and hydraulic separation
 Typical connections: supply and return ports for integration with heating circuits
How to use
Install the buffer tank in a location that provides stable support for its filled weight and allows access for pipe connections and maintenance. Connect supply and return lines according to the heating system design, ensuring correct hydraulic layout to achieve separation between heat source and consumer circuits. Commission the tank following the system manufacturer’s instructions: flush and remove debris from piping before filling, fill with treated water if required by the system, and vent air from the vessel and connected circuits. Observe recommended operating temperatures and pressures for the overall heating installation.
Usage recommendations
Use the KOSPEL SV-500.1 in systems where a non-enamelled interior is acceptable; consider corrosion protection measures such as sacrificial anodes or compatible water treatment when appropriate. Ensure insulation remains intact and periodically inspect connections and the insulation jacket to minimize heat loss and maintain system efficiency.
