Galmet two‑shell horizontal water heater SGW(L)P 100 L in polyurethane insulation (20-104700)

Galmet two‑shell horizontal water heater SGW(L)P 100 L in polyurethane insulation is a 100‑litre indirect hot water storage tank designed for domestic and small commercial installations. The unit uses a double‑jacket construction to receive heat from an external source into the outer shell, transferring thermal energy to the inner storage cylinder. Polyurethane insulation reduces standby heat losses and supports stable hot water delivery while the horizontal layout enables installation in limited-height spaces and mounting on compatible walls or floors.

Advantages

The double‑shell design separates the heating jacket from the potable water cylinder, enabling indirect heating from boilers, heat pumps, or solar circuits without direct mixing. Polyurethane insulation provides effective thermal resistance with a compact insulation layer, improving energy efficiency and reducing heat loss. The horizontal orientation makes the tank suitable for under‑counter or low‑clearance locations and allows flexible piping arrangements. Construction and materials are selected for corrosion resistance and durability suitable for routine residential and light commercial use.

Suitable for

• Domestic hot water storage in homes and apartments
• Small commercial applications such as offices, cafés, or workshops
• Systems using boilers, heat pumps, or solar thermal collectors as the heat source
• Installations with limited vertical space or where horizontal mounting is preferred

Key specifications

• Capacity: 100 litres of domestic hot water storage
• Construction: two‑shell (double jacket) design for indirect heating
• Insulation: polyurethane foam for reduced standby heat loss
• Orientation: horizontal layout suitable for wall or floor mounting
• Connection: external jacket connections for heat source integration (compatible with boilers, heat pumps, solar systems)
• Application: designed for domestic and small commercial installations

How to use

Integrate the SGW(L)P 100 L into a closed heating circuit so that the external heat source circulates through the jacket around the storage cylinder. Connect cold‑water inlet and hot‑water outlet according to local plumbing codes and ensure proper venting and pressure safety devices are installed in the system. Mount the horizontal tank on a suitably rated support or compatible wall brackets, verify level alignment, and connect the heat source to the jacket loop using appropriate fittings and expansion/protection components. Commission the system by filling, bleeding air from the jacket and potable circuit, and checking for leaks and correct temperature regulation.

Usage recommendations

Use water‑treatment measures where recommended for your water hardness to limit scaling inside the storage cylinder. Schedule periodic inspections of connections, insulation condition and safety devices. Ensure that compatible temperature and pressure relief valves, expansion vessels and control equipment are installed per local regulations and manufacturer instructions to maintain safe and efficient operation.
