Wanit wants renewable energy in every homes. People would like to use renewable energy for their homes but they don’t because the investment is important, they are complex to install and maintain, and finally, even with subsidies, not cost effective, especially for small installation. Since it becomes mandatory, they are unhappy. Still, installing them should be as simple and cheap as plugging a few photovoltaic panels into its water heater that stores or uses all the free solar electricity, every day. This is what Wanit does, with the guarantee of a reduction in hot water bill by up to 85% for decades. A small area exposed to the sun can finally be enhanced. Everyone can contribute on their own scale. Wanit also manage the charge and discharge of batteries, that increase storage capacity, and allows night heating while protecting them to ensure a lifespan of more than 10 years. For larger photovoltaic fields, Wanit significantly improves self-consumption, reducing losses and increasing profitability. The Wanit system guarantees the thermal treatment of heated water to ensure its potability. Thanks to its high compactness that allows it to be installed close to the needs and the satellite boiler, the Wanit system allows the elimination of energy and water losses from the distribution pipes and remote storage, as well as the removal of hot water loops so energy-intensive. As a result, the need for copper in construction is reduced.
