## Long description

The Immergas USB 125 V3 is a 125-litre hot water storage tank designed as an indirect cylinder for integration with boilers, heat pumps or other central heat sources. The unit provides stored domestic hot water for household taps, showers and appliances while maintaining temperature stability through hydraulic coupling to a primary heating circuit. The inner surface is treated to resist corrosion, supporting long-term operation and preserving water quality in domestic systems.
Advantages
The design of the Immergas USB 125 V3 offers a compact footprint with a 125 L usable volume suitable for small to medium households. Its indirect cylinder layout separates primary heating fluid from potable water, reducing contamination risk and enabling flexible use with different heat sources. Corrosion-resistant inner coating and standardized hydraulic connections simplify installation and maintenance while helping maintain consistent hot water delivery.
Suitable for
Residential apartments and houses with a boiler or heat pump
Systems requiring indirect hot water storage for taps and showers
Replacement or upgrade of existing small-to-medium domestic cylinders

Key specifications
Nominal capacity: 125 litres
Type: indirect hot water storage cylinder
Inner surface: corrosion-resistant coating
Connections: hydraulic ports for primary heating circuit and potable water

How to use
Install the Immergas USB 125 V3 according to local plumbing and heating regulations, connecting the primary heating circuit to the cylinder heat exchanger ports and the potable water inlet and outlet to the domestic supply lines. Commission the system by filling the tank and primary circuit, purging air from the connections, and setting appropriate temperature controls on the boiler or heat source. After commissioning, the cylinder stores heated water delivered by the primary heat source and supplies it to domestic outlets on demand.
Usage recommendations
For optimal performance, ensure the storage tank is sized to match household hot water demand and the heating source capacity. Schedule periodic inspection of hydraulic connections and the condition of the inner coating, and follow local maintenance practices for water heaters to avoid scale buildup and to maintain hygiene and efficiency.
