A perfect pair: load management and thermal storage
Artur Kosielski’s villa overlooking Lake Wörth in Austria is not just architecturally unique. This 60 year old building has also got the edge in terms of technology. By installing a Fronius Ohmpilot, the owner is not only demonstrating good taste, but is also reducing his heating and hot water bills.
85% self consumption
As the 200 m² house is primarily used during the summer months and at weekends, the owner decided to install electric under-floor and wall heating. The Fronius Ohmpilot significantly reduces the demands on these systems, while increasing their service life at the same time. The intelligent controller heats the hot water for the taps in the buffer storage tank and supplies the heating system with PV energy. This enables the use of solar energy that would have otherwise been fed into the grid. The result: 85% self-consumption.
“Our experience with the Fronius Ohmpilot has been very positive. It is extremely user-friendly, and installation and commissioning were very straightforward,” according to Fronius System Partner Karl Heinz Knees.
