Rudi Kronovšek developed the first domestic heat pump in 1976. After seeing that there had been no improvements in this field for decades, the technology had not progressed, and the devices were outdated, he decided to embark on an independent path. He saw this as an opportunity to create his own brand and recognized that heat pump technology offered much potential for further development. At the same time, he was already aware of the significant advantage of heat pumps—the dual heating and cooling effect simultaneously.
