Water heater Galmet SGW(S) 120 L wall-mounted storage tank with spiral coil, left-side connections, electric controller

Galmet SGW(S) 120 L is a wall-mounted storage tank designed for domestic hot water accumulation and circulation. It features an integrated spiral coil heat exchanger that enables connection to an external central heating source. The unit has left-side hydraulic connections and an electric controller for setting and maintaining water temperature, making it suitable for residential and small commercial installations where efficient hot water storage and indirect heating are required.

Advantages

The spiral coil design provides efficient heat transfer between the external heating circuit and the stored water, reducing warm-up times. Wall-mounted construction saves floor space and simplifies installation in utility rooms or plant closets. Left-side connections standardise pipe routing for certain layouts and can simplify plumbing work. The built-in electric controller offers straightforward temperature adjustment and stable temperature maintenance without additional control devices.

Suitable for

• Residential homes with central heating systems that require domestic hot water storage
• Small commercial premises such as offices, guest houses or small workshops
• Installations where wall-mounted tanks optimise space usage
• Systems combining an external heat source (boiler, heat pump, solar thermal) with a buffer for domestic hot water

Key specifications

• Storage capacity: 120 litres
• Configuration: wall-mounted storage tank with integrated spiral coil heat exchanger
• Hydraulic connections: left-side pipe connections for supply and return
• Temperature control: built-in electric controller for setting and maintaining water temperature
• Primary circuit compatibility: designed for connection to central heating circuits or external heat sources via coil
• Application: domestic hot water accumulation and circulation

How to use

Mount the tank on a structurally suitable wall following the manufacturer's installation instructions and local plumbing codes. Connect the spiral coil to the external heat source using appropriate supply and return piping on the left-side connections. Connect the domestic cold water inlet and hot water outlet to the building plumbing system. Fill and vent the system to remove air from the coil and tank. Use the electric controller to set the desired storage temperature and monitor system operation. Periodically check safety devices, pressure relief valve operation and inspect for leaks.

Usage recommendations

For reliable performance, use water treatment appropriate to local water quality, verify that the external heat source parameters match the coil design, and schedule regular maintenance including inspection of anode protection (if fitted), pressure relief valve testing and decalcification in hard-water areas.
