Wallas 16L On-demand hot water accumulator

Boats usually have limited space, so there was a need to make a smaller, energy-efficient charger that better fits the space.

We wanted to make a space-saving, angular shaped charger instead of the round one commonly used on the market.

Because we wanted to make an angular shape instead of a round one, the operating principle had to be reversed due to the pressure resistance of the tank, the round design withstands the pressure better due to its shape, the square one does not, therefore the water pressure is only inside the flexible wave-like tube inside the tank, the pressure is not applied to the external structures of the tank at all.

The heat transfer capacity of a corrugated flexible pipe is significantly better than that of a smooth-walled pipe, the heat transfer surface is more than in a smooth-walled pipe.
