FreeFlow Solar Water Heating
Thermosiphon systems such as AET's Free Flow Series are automatic, simple, and reliable. They don’t require a pump or control and there are no moving parts, allowing for minimal maintenance concerns.
Thermosiphon systems are not only efficient but also highly eco-friendly, making them an excellent choice for homeowners looking to reduce their carbon footprint. By utilizing the natural process of convection to heat and circulate water, these systems eliminate the need for external energy inputs beyond sunlight, resulting in lower energy costs over time. The AET FreeFlow Series stands out for its durability and adaptability, with optional features such as an electrical heating element for added convenience during cloudy days or periods of high demand. This innovative design ensures consistent hot water availability while keeping operational complexity to a minimum, making it a practical and sustainable solution for your home's water heating needs.

How Thermosiphon Water Heaters Work
Your FreeFlow Solar Water Heating system is known as a “passive” solar water heater because it does not require mechanical pumps, controllers, or any moving parts to make hot water. Thermosiphon solar systems work on the principle of natural convection, or the fact that heated liquids rise.
The FreeFlow storage tank can be equipped with an optional electrical heating element that can provide hot water during periods of inclement weather or high use. In two-tank systems, the supplemental electric or gas water heater will provide backup water heating if necessary.
What is a Thermosiphon System?
A Thermosiphon system is a system where the heated water in the solar collectors rises up into the storage tank by natural Thermosiphon action. Thermosiphon action occurs when water that is heated in the collectors expands, becoming lighter, allowing colder, heavier water to fall by gravitational force to the bottom of the collector. The cold water falling to the bottom of the collector pushes the hotter, lighter water back up into the storage tank. This natural action, commonly known as Thermosiphon action, occurs without any moving parts or auxiliary electrical energy input to the system.
