Buffer tank Galmet SG(B) 60 L wall-mounted with polyurethane insulation and metal casing

The Galmet SG(B) 60 L buffer tank is a compact, wall-mounted accumulator designed to store and stabilise water in heating systems. With polyurethane thermal insulation and a durable metal casing, the unit reduces heat loss and supports consistent system temperature. The 60-litre volume helps to minimise short cycling of burners and pumps, improving operational efficiency in residential and small commercial heating installations and simplifying integration with boilers, heat pumps and other heat sources.

Advantages

The polyurethane insulation provides effective thermal protection while keeping the tank compact for wall mounting. The metal outer casing offers mechanical durability and a finished appearance suitable for utility rooms. By increasing the system’s effective water content, the buffer tank reduces pump and burner cycling, which can extend component life and stabilise heat delivery. The simple cylindrical design and standard connection layout facilitate installation and maintenance.

Suitable for

• Residential central heating systems to stabilise temperature and reduce short cycling
• Small commercial heating installations requiring additional system inertia
• Integration with boilers, heat pumps and solar thermal systems to buffer heat production
• Situations where wall-mounted equipment is preferred due to floor-space constraints

Key specifications

• Nominal volume: 60 litres
• Mounting type: wall-mounted
• Thermal insulation: polyurethane foam
• Outer casing: metal
• Function: hydraulic buffer/accumulator for heating systems

How to use

Install the buffer tank on a suitably rated wall bracket or support according to local regulations and the manufacturer’s installation instructions. Connect the tank to the heating circuit using appropriate fittings and check valve arrangements; ensure correct positioning of supply and return connections to promote proper stratification and mixing. Fill the system with treated water and perform a controlled pressure test. Commission the heating system following standard procedures, confirming that pumps, valves and controls operate as intended with the buffer tank in place.

Usage recommendations

Use corrosion-inhibited or otherwise conditioned water compatible with closed heating systems to protect internal surfaces. Allow service access around the mounted tank for maintenance checks and ensure insulation and casing remain intact to preserve thermal performance.
