The Ecotube is an advanced solar water heating system from Riomay, widely recognised as a world leader in the design and construction of vacuum tube devices.
The Riomay Ecotube forms part of a simple, yet highly efficient energy transfer system that can heat water throughout the year. Whether your system is domestic, commercial, small or large, the principle is the same.
The heat transfer fluid passing through each panel is a solution of water and non-toxic antifreeze. This fluid absorbs heat from the Ecotube array and is pumped to a heat exchanger (coil) in the hot water tank. The heat then passes into the water, and the fluid is pumped back to the solar panel.
The pump is controlled by an electronic device that detects the temperature difference between the solar panel and the hot water tank. When the temperature in the panel is lower than the temperature in the tank, the system remains on standby. But when the sun raises the temperature in the panel to 4°C above the temperature in the tank, the temperature controller switches on the pump.
The system prevents energy losses at night and during the darkest days of winter, and the heat transfer fluid eliminates any risk of freezing.
