## Long description

Galmet SGW(L)x2 140 L is an indirect hot water storage tank with a double U-shaped coil designed for domestic and small commercial hot water systems. The 140-litre capacity provides buffer storage for potable hot water, while the double U-shaped heat exchanger coil ensures efficient heat transfer from an external heat source such as a boiler, heat pump or solar thermal array. Polyurethane foam insulation around the cylinder reduces standby heat loss and helps maintain stable water temperature for extended periods.
Advantages
The double U-shaped coil increases the heat exchange surface area without enlarging the tank footprint, enabling faster and more uniform water heating when connected to external sources. Polyurethane foam insulation offers a high level of thermal protection, lowering heat loss and improving system efficiency. The vertical cylinder layout and corrosion-resistant inner surface ensure reliable operation in typical domestic and light commercial installations.
Suitable for
Integration with gas or oil boilers as an indirect hot water store
Connection to heat pumps for domestic hot water production
Use with solar thermal systems as a storage buffer
Small commercial or multi-family buildings requiring centralized DHW storage
Key specifications
Nominal capacity: 140 litres
Heat exchanger: double U-shaped coil for indirect heating
Insulation: polyurethane foam for reduced standby losses
Design: vertical cylinder suitable for floor-mounted installation
Application: indirect domestic hot water storage compatible with boilers, heat pumps and solar thermal systems
How to use
Install the storage tank according to local codes and the manufacturer’s installation instructions, placing it on a stable, level surface with adequate access for service. Connect the double U-shaped coil to the external heat source supply and return lines, and connect the potable water inlet and hot water outlets to the building plumbing. Ensure appropriate safety devices such as pressure relief valves, check valves and thermal insulation on pipework are fitted. Commission the system by filling the tank, purging air from the coil and heating circuit, then check for leaks and verify correct thermostat operation before regular use.
Usage recommendations
To maintain thermal performance and service life, follow regular inspection and maintenance: check insulation integrity, inspect connections and valves, and perform periodic water quality checks to reduce corrosion and sediment buildup. Match coil flow rates and temperatures to the heating source’s recommended settings to optimise heat transfer efficiency.
