## Long description

Ferroli ECOUNIT F 300 is a hot water storage tank designed for domestic and small commercial domestic hot water (DHW) systems. The tank features a single spiral coil heat exchanger that allows efficient transfer of thermal energy from an external boiler or other heat source into stored potable water. With a nominal heat input of 64.25 kW, this unit provides centralized storage and stable hot water delivery for buildings where consistent temperature and flow are important.
Advantages
The single spiral coil design ensures efficient heat exchange while maintaining separation between the heating circuit and stored domestic water. The tank construction supports continuous hot water availability and reduces short-cycling of the primary heat source by providing a buffer volume. Designed for easy integration with existing boiler or heat generator systems, the unit is intended to improve operational stability and simplify hydraulic connections in small-scale commercial and residential installations.
Suitable for
Domestic hot water supply in single-family homes and multi-family apartments
Small commercial buildings such as offices, guesthouses, and small retail premises
Systems using an external boiler, heat pump, or other centralized heat source
Installations that require centralized storage to stabilize hot water temperature and flow
Key specifications

How to use
Install the Ferroli ECOUNIT F 300 according to local plumbing and heating regulations, ensuring correct hydraulic connections between the external boiler or heat source and the internal spiral coil. Connect the potable water supply and distribution lines with appropriate valves, safety devices, and temperature controls. Commission the system by filling and venting the primary and domestic circuits, then verify the heat transfer, temperature setpoints, and safety functions. Regularly inspect the unit and maintain associated controls and safety components as part of routine system service.
Usage recommendations
For reliable performance, match the tank capacity and coil sizing to the heat source output and expected DHW demand. Use compatible corrosion protection and water treatment measures if required by local water quality. Follow manufacturer guidelines and applicable codes for pressure relief, expansion vessels, and safety thermostats to ensure safe operation.
