How Does It Work?

Optimizing Hot Water Storage with TET (Thermal Exchange Tower)

Storing Hot Water is expensive!

With the Thermal Exchange Technology from IEES, we are introducing the next level in storing ENERGY. Energy to heat potable water up to 95ºC, but up to 25% more efficient compared to a steel tanks, boilers or calorifiers.

In Normal high pressure steel tanks, water would be heated with elements, and when hot water is consumed, cold water would enter the bottom of the tank, which could lead to mixing of hot and cold water inside the tank, which in return destroys the stratification layers. (Also known as blending)

The TET system works with low pressure, and hot water is generated by either Element, Gas, Heat recovery, Thermal exchange, Solar or Heat Pumps. The tank itself is a closed system containing a body of water, purely for heat storage, and is at normal atmospheric pressure. The fresh potable (drinking) water which is under municipal pressure enters the tank through a stainless steel heat exchange coil system, which spirals from the bottom to the top of the tank, absorbing the latent heat from the water inside the tank, thus leaving at the top at around 60 degrees Celsius. By separating the two bodies of water, the TET system has no effect on the stratification layers, and therefore makes the tanks more efficient than conventional boiler systems.

Further by removing the drinking water from the tank, the risk of water contamination has been totally removed. Water born diseases that thrive on standing water such as Legionella are minimized.

On bigger vessels ranging from 1500L up to 25 000l all the tanks are manufactured modular, and are assembled on site as per sketch illustration below.
