Decentralized Efficiency

When hot water needs to travel from the basement to the third floor, it loses a significant amount of temperature along the way. As a result, more than twice the amount of water needs to be heated for one liter to arrive at the right temperature upstairs.

Daniel Rupp addresses this energy waste with his start-up REKS. In Hard, he develops and manufactures the 2.0 version of the tile stove. Kandela is connected to district heating, natural gas, or air heat and ensures decentralized, hygienic, transparent, and efficient hot water, heating, and possibly cooling in each residential unit.
