The Helios Smart GW-60-2/0.39-2 (60L) is a wall-mounted hot water heater designed to operate with direct supply from a photovoltaic panel (DC), with the ability for backup operation from the electrical grid (AC). It features a dual heating system: one DC resistance for utilizing solar energy and one AC resistance for use when solar production is insufficient or faster heating is required. The switch between photovoltaic and electrical supply is automatic, ensuring efficient and reliable operation.

The device is single-phase (220–230V), suitable for indoor installation and made with an enameled tank for durability and hygiene. Additionally, it incorporates basic protection functions, such as overheating and leakage protection, while supporting smart control via WiFi for remote monitoring and management.
