The Envola System is an innovative, holistic and most sustainable approach to enable smart and efficient HVAC solutions for buildings. Especially for new large scale projects and fabricated housings with sustainable building Technologies, Envola offers enormous value-added. Envola has given the heat pump an integrated storage tank. This allows the Envola #storageheatpump to achieve unprecedented Energy efficiency. Thanks to the storage tank, the system works efficiently even when conditions are unfavorable for conventional heat pumps. So the heat pump provides efficient heating even when it's cold outside. And it cools efficiently even when it is warm outside. At the same time, the storage tank, in combination with an exhaust air heat exchanger, enables energy recovery from the exhaust air of buildings. This is not only innovative, but also saves energy and, above all, investment costs. Envola is funded by the European Union | European Innovation Council and investBW for its innovative potential.
