Storage water heater Galmet wall-mounted SGW(S) 80 L with spiral coil, left-side connections

Galmet SGW(S) 80 L is a vertical, wall-mounted storage water heater designed for domestic hot water preparation. The cylinder holds 80 litres and contains an internal spiral heat exchanger (coil) that allows connection to an external heat source such as a boiler or solar thermal system. The unit is configured with left-side hydraulic connections to facilitate integration into plumbing layouts where pipework is routed from the left.

Advantages

The internal spiral coil provides efficient heat transfer between the external heat source and stored potable water while keeping the primary and domestic circuits hydraulically separated. Wall-mounted vertical design saves floor space and simplifies installation in utility rooms or garages. The left-side connection arrangement supports common installation orientations and can reduce piping runs when positioned accordingly. The 80-litre capacity is intended for typical residential hot water demands, balancing storage volume and recovery when paired with a suitable heat source.

Suitable for

• Small to medium residential properties requiring domestic hot water storage
• Systems with an external boiler or solar thermal collectors as the primary heat source
• Installations where left-side hydraulic connections match existing plumbing
• Wall-mounted installations with limited floor space

Key specifications

• Storage volume: 80 litres
• Mounting type: vertical wall-mounted cylinder
• Heat exchanger: internal spiral coil (single coil)
• Hydraulic connections: left-side arrangement
• Application: domestic hot water preparation with external heat source

How to use

Install the Galmet SGW(S) vertically on a load-bearing wall using appropriate fixings and clearances as per installation instructions. Connect the domestic cold-water inlet and hot-water outlet, and link the coil circuit to the external heat source supply and return. Fill and vent both the domestic and primary circuits before commissioning. Operate the heater together with the chosen heat source, controlling temperature and charging cycles from the boiler or solar system controller. Regularly inspect for leaks, correct pressure levels, and proper operation of any safety or control devices.

Usage recommendations

For optimal performance, match the coil capacity and flow rates to the external heat source specifications and use appropriate corrosion protection and water treatment if required by local water conditions. Schedule periodic maintenance checks, including inspection of hydraulic connections, anode condition (if present), and calibration of control devices. Ensure installation and maintenance are performed by qualified personnel in accordance with local regulations.
