Heating water with photovoltaics
Fronius Ohmpilot and Fronius Energy Package lead the way to maximum independence
Did you know that homeowners like you can guard against rising electricity prices with the Fronius Ohmpilot? In addition to powering consumers such as your washing machine and lighting with solar energy, you can also harness the clean power of the sun to heat water. If you have already had an energy-storage solution installed in your home, such as the Fronius Energy Package, then full energy independence is now within your reach.

Heating water with any PV system
The Fronius Ohmpilot can be easily integrated into any PV system. Regardless of your inverter, the Fronius Ohmpilot is the perfect choice for new and existing installations alike. What is more, it is very easy to install and set up.
Relieving strain from the heating system
With the Fronius Ohmpilot it is possible to deactivate your existing heating system for hot water from April to October. As a result, system wear is dramatically reduced and its service life is extended. The energy costs associated with the heating system are also reduced. Owners of an oil-based heating system also need less fuel – both saving money and protecting the environment.
Grid independence with the Fronius Energy Package and Fronius Ohmpilot
Maximum energy independence can be achieved through a combination of the Fronius Symo Hybrid with energy-storage system, such as the Fronius Solar Battery, and the Fronius Ohmpilot. Any solar power that is not used during the day can be stored and made available in the evening or at night. You are also able to use the surplus solar power to heat water in the boiler or buffer storage tank. Thanks to the built-in emergency power function of the Fronius Solar Battery, even a power outage does not pose any risks.
