Wanit TWIN + SolarConnector

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, even with subsidies, not cost effective, especially for small installation. At Wanit, we thought it should be as simple and economical as plugging a few photovoltaic panels into its water heater that stores or uses all the free solar electricity every day. Families can reduce their hot water bill by up to 85% for decades. A buffer battery can be plugged for night heating & extra storage. The system guarantees their lifetime. A small sunny area can finally be enhanced. With no operating bearing, this PVheater follows the production curve without loss. For larger PV fields, Wanit improves self-consumption and increase profitability. Thanks to its high compactness and the satellite boiler, the Wanit system allows the elimination of distribution pipes and water loops (less copper, energy and water losses)
