Water heater Galmet NEPTUN2 Kombi Elektronik SGWS c.w.u. 100 L left-mounted (06-104771)

Galmet NEPTUN2 Kombi Elektronik SGWS c.w.u. 100 L left-mounted is a 100‑litre domestic hot water storage heater designed for left‑side hydraulic connections and combined operation with central heating systems. The unit integrates electronic controls for temperature management and monitoring, and its storage capacity makes it suitable as a sanitary hot water buffer in apartments, houses or small commercial installations. The left‑mounted configuration is intended for installations where pipework and room layout favour connection points on the appliance's left side.

Advantages

The heater provides stable storage of hot water with electronic temperature regulation that helps maintain setpoint accuracy and reduces temperature fluctuations. Its combi design enables integration with a central heating system, allowing the same unit to contribute to both domestic hot water supply and heating circuit compatibility. The left‑side connection layout simplifies installation in specific plumbing layouts and can reduce additional piping. The 100 L capacity balances hot water reserve and compact footprint for typical residential installations.

Suitable for

• Residential apartments and single‑family homes requiring a 100 L hot water buffer
• Installations where left‑side hydraulic connections are preferred or required
• Combined systems integrating domestic hot water storage with central heating
• Renovation projects replacing older storage heaters with an electronic combi model

Key specifications

• Storage capacity: 100 litres
• Mounting orientation: left‑side hydraulic connections
• Control type: electronic temperature control and monitoring
• Application: domestic hot water (sanitary) with compatibility for central heating circuits
• Suitable installation locations: utility rooms, boiler rooms, or wall‑mounted spaces designed for left‑mounted units

How to use

Connect the heater to the domestic hot water and heating circuits following local plumbing and electrical regulations. Configure the electronic control panel to the desired temperature setpoint and verify safety devices such as pressure relief valves and thermostats are installed and operational. After filling the tank and venting air from the system, allow the unit to reach operating temperature and check for leaks at all connections. For combined heating setups, coordinate control logic between the boiler/heat source and the heater so that charging and priority functions operate as intended.

Usage recommendations

Set the electronic temperature to a level that balances energy use and legionella mitigation (commonly 55–60 °C for stored water) and use periodic inspection of anode(s) and pressure relief devices to maintain longevity. For optimal integration with central heating, follow Galmet installation guidance and ensure regular maintenance by a qualified technician.
