Wombat Evacuated Tube Nonpressurized Thermosiphon Solar System

Product Description

Wombat ET non-pressurized thermosiphon solar water heaters are a great choice for consumers who want a cost effective hot water solution. When mounted on the roof the house is provided with gravity fed hot water. In high solar radiation areas, Wombat solar water heaters can be the sole energy source for hot water supply. In cooler climates, Wombat systems can provide pre-heated hot water which saves on traditional energy costs such as electricity or gas. The tank has an optional electrical heating element for boosting for when the water is not hot enough.

System Operation

The solar heating occurs through a process called thermosiphoning, which allows the solar collector to heat the storage tank without the need for a circulation pump.

The basic operation is as follows:

• Cool water from the bottom of the storage tank falls to the bottom of the evacuated tube.

• As the water heats up it rises back up into the tank, gradually heating the tank throughout the day.
