Galmet buffer tank 500 L, black, insulated (model 70-500000)

Galmet buffer tank 500 L, black, insulated (model 70-500000) is a 500-litre thermal storage vessel designed for integration with central heating systems, heat pumps and biomass boilers in residential and small commercial installations. The insulated steel tank stores heat produced by a boiler or heat source and releases it when required, reducing short cycling of heat generators and smoothing temperature fluctuations in the heating circuit. The black finish and external insulation improve heat retention while the vertical design minimises floor space requirements.

Advantages

The buffer tank provides stable thermal buffering to reduce on/off cycles of boilers and heat pumps, which helps extend equipment life and improve system efficiency. External insulation preserves stored energy and lowers standby losses, while the 500-litre capacity allows accumulation of surplus heat for later use. The compact vertical profile facilitates installation in plant rooms or basements with limited floor area, and the black surface offers a practical, neutral appearance that integrates with technical spaces.

Suitable for

• Residential central heating systems with gas, oil or biomass boilers
• Heat pump installations requiring thermal storage and cycle stabilization
• Small commercial buildings seeking improved heat distribution and reduced generator cycling
• Systems where temporary storage of surplus thermal energy is needed (e.g., during low demand periods)

Key specifications

• Nominal volume: 500 litres
• Orientation: vertical
• External colour: black
• Insulation: factory-applied external thermal insulation
• Application: heating system buffer and thermal energy storage
• Typical connections: hydraulic ports for supply, return and sensor fittings (check installation documentation for exact locations)

How to use

Install the buffer tank according to local regulations and the manufacturer’s installation instructions, ensuring adequate support for its filled weight and access to hydraulic connections. Connect supply and return lines from the heat source and heating circuit to the appropriate ports, and fit required valves, pumps and sensors to manage flow and temperature stratification. Commission the system by filling the tank, purging air from hydraulic circuits and verifying pump operation and control settings so that the heat source charges the tank and the heating circuit draws stored energy as designed.

Usage recommendations

Position the tank on a level, load-bearing surface with space for servicing. Match the buffer capacity to the heat source and load to obtain effective reduction of cycling. Use appropriate insulation on adjacent pipework and install recommended safety and control devices (pressure relief, expansion vessel, temperature sensors) to ensure safe and efficient operation.
