Galmet hot water storage tank SGW(S) 140 L wall-mounted with spiral coil left, electric controller (06-144771)

Galmet SGW(S) 140 L is a wall-mounted domestic hot water storage tank with a 140-litre capacity and an internal spiral heat exchanger positioned for left-side hydraulic connection. The unit is intended for indirect water heating and includes an electric controller for setting and monitoring the tank temperature. It is designed for integration with boilers, heat pumps or other heat sources to provide stored sanitary hot water for households and small commercial installations.

Advantages

The tank’s 140 L capacity balances storage volume and compact wall-mounted design to save floor space while providing a reliable buffer of hot water. The internal spiral coil enables efficient heat transfer from an external heat source, while the left-side coil connection fits installations with predefined piping layouts. The built-in electric controller affords straightforward temperature setting and monitoring without the need for separate control equipment. Corrosion-resistant internal surfaces and thermal insulation reduce heat losses and extend service life.

Suitable for

• Domestic hot water supply in single-family houses and apartments
• Small commercial premises such as offices, guesthouses or shops
• Integration with boilers, solar thermal systems or heat pumps
• Installations requiring wall-mounted storage to save floor space

Key specifications

• Nominal capacity: 140 litres
• Mounting: wall-mounted space-saving design
• Heat exchanger: internal spiral coil with left-side hydraulic connection
• Controller: integrated electric temperature controller for setpoint and monitoring
• Function: indirect domestic hot water storage for integration with external heat source
• Insulation: factory-fitted thermal insulation to limit standby losses

How to use

Connect the spiral coil to the external heat source following the installation guidelines supplied by the heat source and local plumbing codes, ensuring the coil’s left-side orientation matches the piping plan. Mount the tank securely on a load-bearing wall using appropriate fixings and observe the required clearances for service access. Fill the tank and the coil circuits, purge air from the system, and set the desired temperature on the electric controller. Commission the system by checking for leaks, correct pump operation, and stable temperature control before regular use.

Usage recommendations

For reliable operation, maintain regular inspections of connections, sacrificial anode (if present) and insulation condition. Use corrosion-inhibiting measures and water treatment where required by local water quality. When integrating with boilers or heat pumps, follow the manufacturer’s hydraulic schematics and install safety devices such as pressure relief valves and non-return valves as specified.
