EcoHeat PRO Pressurized Solar Panels
Ferroli EcoHeat PRO are pressurized solar panels that operate by exchanging energy between the collector and the water in the reservoir. As the vacuum tubes absorb solar energy, the heatpipe transfers heat to the water in the reservoir. The liquid in the heatpipes turns into vapor, rises to the condenser, heat passes through the heat exchanger, and the vapors condense back into liquid, returning to the base of the heatpipe. This process continuously heats the cold water. The system is pressurized, supplying hot water under pressure without the need for a pump. It offers high efficiency due to an increased heat exchange surface area provided by the 18mm bulb heatpipe.

Diagram Description: Schematic of the EcoHeat PRO pressurized solar system. It shows a water reservoir connected to solar collectors via heatpipes. Key components include a 6-bar safety valve, an automatic air vent, a cold water inlet, and a connection to the consumer. The system operates with pressurized water, eliminating the need for a pump.
EcoSole Non-Pressurized Solar Panels
EcoSole non-pressurized solar panels for water heating rely on natural water circulation between the vacuum tubes and the water reservoir. As water in the vacuum tubes heats up, it naturally rises into the reservoir, while cooler water from the reservoir flows into the vacuum tubes, driving circulation throughout the system.

- Outer reservoir: Stainless steel
- Insulation layer: Polyurethane foam
- Heat retention: 72h

Diagram Description: Schematic of the EcoSole non-pressurized solar system. It illustrates a water reservoir with a float and air vent, connected to vacuum tubes exposed to sunlight. Cold water enters the tubes, heats up, and rises naturally to the reservoir, creating a continuous circulation. The diagram shows the water flow path and key components like the reservoir, vacuum tubes, and support structure.
Ecotube NEW Evacuated Tube Solar Panels
Ecotube NEW are solar panels with heatpipe technology. They are available in three variants: Ecotube NEW 15 (15 vacuum tubes), Ecotube NEW 20 (20 vacuum tubes), and Ecotube NEW 25 (25 vacuum tubes). The selective coating on the inside of the vacuum tubes converts solar energy into thermal energy and transfers heat to the heatpipes via fins. The liquid in the heatpipes turns into vapor, rises to the condenser, heat passes through the heat exchanger, and the vapors condense back into liquid, returning to the base of the heatpipe. Heat is transferred to the heat transfer fluid (antifreeze or water) through the copper pipe. This heat transfer creates continuous circulation in the heatpipe as long as the collector is heated by the sun. Annual energy production in Wurzburg conditions is over 675 kWh/sqm.
Advantages:
- No risk of freezing or bursting in winter (tubes do not contain water).
- Compact structure, easily adaptable to mounting location.
- Functions even if one or more tubes are broken.
- Easy tube replacement.

Notes
Electric Heater
For pressurized/non-pressurized solar panels (EcoHeat/EcoSole models). Due to climatic changes, for example, when sunlight is weak, you can use the electric resistance to heat the water in the collector. If installing the electric resistance without connecting it to a controller, ensure it is equipped with a residual current device (overvoltage protection) for safe use. Remember to turn it off before showering. Washing or taking a bath with electrical appliances nearby is strictly prohibited.
Antifreeze -30°C
Antifreeze -30°C is intended for pressurized solar installations. Applications include improving heat transfer in radiators, air conditioning units, and heating, reducing friction by 45%, and providing flocculant, anti-limescale, anti-algae, and anti-freeze effects. To use, introduce it into the installation as is. For applications with a special freezing point, the product can be supplied upon request.
