## Long description

KOSPEL SV-300 non-enameled insulated buffer tank is a 300 L capacity vessel for accumulation and stabilization of heating system water. It is designed to reduce short cycling of heat sources and to improve overall thermal management in residential and small commercial heating installations. The tank features thermal insulation to minimize standby heat loss and a non-enameled internal surface that is compatible with typical heating system water treatments.
Advantages
The buffer tank decreases boiler or heat pump cycling by providing additional hydraulic volume, which leads to more stable system operation and reduced wear on the heat source. Thermal insulation reduces heat losses during idle periods, improving system efficiency. The non-enameled interior simplifies manufacturing and maintenance in systems where enameled surfaces are not required. The unit’s capacity and dimensions are suitable for integration into compact plant rooms.
Suitable for
Residential central heating systems with boilers
Heat pump installations requiring hydraulic separation and storage
Solar thermal systems as a hydraulic buffer
Small commercial heating systems with variable loads
Key specifications
Nominal volume: 300 liters
Construction: non-enameled internal surface with external thermal insulation
Purpose: hydraulic accumulation and stabilization of heating system water
Compatibility: suitable for connection to boilers, heat pumps and solar thermal systems
Application environment: residential and small commercial installations
How to use
Install the buffer tank according to local regulations and the installer’s instructions, ensuring correct hydraulic connections, proper air venting and secure mounting. Connect the tank to the heating circuit with appropriate pipework and fittings, observing recommended flow directions and pressures for the overall system. Verify insulation integrity and check for leaks after filling and commissioning. Integrate control and safety devices, such as temperature sensors and pressure relief valves, as required by the heating system design.
Usage recommendations
Use corrosion inhibitors or water treatment methods compatible with non-enameled steel surfaces when specified by the system designer. Size the buffer volume in relation to the heat source capacity and expected load variations to maximize reduction of cycling. Periodically inspect insulation and fittings for damage and maintain proper system water quality to prolong service life.
