Infrared Tankless Hot Water Heater

Clearwater, FL – SioGreen Inc. was founded in 2008 by Henry Mai, who established many small businesses with a great mind for innovation and ingenuity. After a few bad experiences with residential water heaters, Henry Mai quickly understood the need to find a better solution for consumers and aimed to resolve the challenges these products face today.

Previous technology, which accounts for a majority of the homes today, will heat a tank full of water from the inside with metallic heating elements. The elements eventually corrode and efficiency decreases rapidly. This leads to high electricity bills, unhealthy water, and expensive equipment costs for maintenance or product replacement. In most electric tankless designs, water flows past heating coils to produce the on-demand hot water, rather than keeping it stored. However, the results are still the same.

SioGreen Tankless offers Space Savings, Lower Equipment Costs, Improved IAQ/No NOX, Reduced Energy Cost, Environmental Benefits, Maintenance Free Operation, Long Life-Span, Water Conditioning, Safe Recovery Mode and Recyclable Materials.

SioGreen Infrared Tankless Technology

SioGreen today is the only manufacturer in the world that produces an instant hot water system with a Infrared Quartz heating element that serves distributors in North America, Europe, and Asia.

All water heaters rely on a heating element of some type, generally this is in the form of hot metal components.

Normally when the metal elements are introduced to direct contact with water, only the water in the immediate area of the heating element are affected. This can actually reduce the flow rates in the attempt to heat the water.

Infrared technology works on the molecular level and because the far infrared rays affect all of the water it gets hot faster and more thoroughly.

Scientifically the water is clustered with 5-12 water molecules. When the far infrared rays stimulate the clusters, the water molecule movement is activated. This is due to the resonance absorption. The number of water molecules which form the clusters are decreased and the result is activation/agitation of the water.

As a result of this activation the infrared energy is able to heat the excited molecules on an individual basis ensuring the water is thoroughly heated at an accelerated rate. This allows SioGreen is operates at higher flow rates.
