Gravity heating

This unit is part of the alcohol-gravity system.
The inverted T shape is one of its lower 3/4" connector is connected to the upper branch of the boiler's heat exchanger, and the other to the upper outlet of the collector. On the U-shaped filling hole you can fill the system,and the part above the U shape plays the role of the equalization tank.
To continue the installation, we recommend a copper or stainless (inox) throat tube with a rubber (!) seal.
The base 22 mm pipes can be adapted to a larger system by extending the pipe that acts as an equalizing tank.
Recommendation: 22 mm copper or DN16 inox pipe for pipe lengths over 4 meters + 10 cm extension per meter.
