Thermoflex - A green energy solar water heating and storage system

In most residential buildings, hot water consumption and hot water production are not in sync. When hot water is used, a volume much greater than what is actually needed is heated up, leading to unnecessary energy use. Thermoflex™ 16 solves this problem using large hot water reservoir as energy storage. The Thermoflex™ 16 is an off-grid hot water storage system, based on renewable energy (sun and wind). This is an ideal Solution for remote locations that need hot water on regular basis like residential complexes, safari lodges, medical clinics, and others. A 16 CBM double layer water bladder is installed inside the container. Once the water in the bladder reaches the desired temperature (~55 degrees C), the small daily changes in the water temperature, is compensated by solar and wind-turbine sources integrated with the Solution.

Key features

  • The Thermoflex uses 30% less electricity than a regular boiler
