Hot Water Storage Tank Galmet SGW(S) with Spiral Coil 200 L

Galmet SGW(S) with Spiral Coil 200 L is a vertical hot water storage tank designed for domestic hot water applications. The tank includes an internal spiral heat exchanger coil that enables efficient transfer of heat from an external source — for example a boiler or solar thermal system — into the stored water. With a 200-litre capacity, this unit is intended for residential properties and small commercial installations requiring centralized hot water storage with coil-based heat exchange.

Advantages

The internal spiral coil provides a large heat exchange surface area within a compact tank volume, improving thermal transfer efficiency. The tank construction supports stable stored-water temperatures and reduces heat losses when properly insulated. Integration with external heating sources is straightforward, allowing use with boilers, heat pumps or solar thermal collectors. The 200-litre capacity balances storage volume and footprint for homes or small businesses.

Suitable for

• Domestic hot water supply for single-family homes and small apartment units
• Small commercial sites such as offices, guesthouses or shops
• Systems using boilers, solar thermal collectors or heat pumps as primary heat sources
• Centralized hot water installations requiring coil-based heat exchange

Key specifications

• Usable volume: 200 litres
• Heat exchanger type: internal spiral coil for indirect heating
• Orientation: vertical storage tank
• Intended medium: domestic hot water
• Suitable heat sources: boilers, solar thermal systems, heat pumps
• Typical applications: residential and small commercial hot water systems

How to use

Install the Galmet SGW(S) tank according to local regulations and manufacturer installation instructions, ensuring proper connections between the external heat source and the internal spiral coil inlet/outlet. Place the unit on a stable, level base and provide adequate clearance for service access. Connect the cold water supply and hot water distribution lines, fit safety and control devices (pressure relief valve, expansion vessel, thermostatic controls) as required for the system design. Commission the system by filling the tank, purging air from the coil circuit, and bringing the heat source online to achieve the desired hot water setpoint.

Usage recommendations

For optimal performance, insulate external piping and verify the presence of suitable safety and control equipment. When integrating with solar thermal systems, use a compatible controller and check for appropriate antifreeze and fluid quality in the collector circuit. Periodic inspection of sacrificial anodes, pressure relief devices and coil connections will extend service life and maintain safe operation.
