Ferroli ECOUNIT HP 300-1C Inter-accumulator

The Ferroli ECOUNIT HP 300-1C accumulator is designed to efficiently meet the needs of domestic hot water (DHW) in heating installations with gas or oil boilers. With a capacity of 254 liters and made of high-quality vitrified steel, it is ideal for residential or commercial applications that require a reliable and durable solution. The vitrified steel of this accumulator has been treated at 860 ºC according to the S/DIN 4753 standard, ensuring exceptional resistance to corrosion and a long lifespan.

This model from the ECOUNIT HP series stands out for its high heat exchange capacity, thanks to its internal coil with an exchange surface of 3.1 m² and a length of 39.2 meters. This large surface allows for more efficient heat exchange, ensuring that hot water is distributed quickly, achieving a nominal flow rate of 381 liters per hour with a temperature difference of 35 K. Additionally, the hot water preparation time is only 32 minutes, making it an efficient option for continuously supplying DHW.

The Ferroli ECOUNIT HP 300-1C accumulator also includes a standard electric resistance, with an absorbed power of 2,000 W, which allows for the supplementation of hot water supply in situations where the boiler is not operating. This provides flexibility and ensures that the system can maintain a hot water supply at all times, regardless of external conditions.

For added convenience and control, this model includes an analog thermometer (not available in higher capacity versions), allowing for easy monitoring of the water temperature in the accumulator. It also comes with a magnesium anode included as standard, which acts as an additional protection against corrosion, ensuring greater durability of the unit. Furthermore, the ECOUNIT HP 300-1C features a recirculation connection for the DHW system, facilitating a more efficient distribution of hot water in the piping network.

One of the major advantages of this accumulator is its vertical and compact design, with a reduced diameter that allows it to pass through standard doors (<800 mm), making installation easier even in tight spaces. With dimensions of 1,557 mm in height and 620 mm in width, this unit is easy to handle and install in most domestic or commercial spaces.

In terms of energy efficiency, the Ferroli ECOUNIT HP 300-1C is rated in category C, making it a suitable option for those seeking a balance between efficiency and performance. Its IPX4 protection rating ensures that the unit is protected against water splashes, increasing its durability in humid or demanding environments.
