The Fronius Ohmpilot minimises electricity and fuel costs

Wouldn‘t it be lovely if you could produce the majority of your required household energy for yourself? And not just electricity, but heating as well? The Fronius Ohmpilot allows you to use surplus energy from a PV system to heat up your water. What‘s more, it can be installed as an add-on – which is exactly what the Samwald family did to their system in Austria.

The existing oil-powered heating system for the six-person household can now be deactivated for the entirety of the summer, thus reducing its usage and extending its service life. This has also lead to reduced fuel costs - a saving of over 430 litres of oil every year.Steinbach Austria

“We decided to invest in a Fronius Ohmpilot because we wanted to lower our electricity and fuel costs, to increase our rate of self-consumption and to reduce our CO₂ footprint,” says system owner Stefan Samwald.
