Property description
The house has been extensively renovated and energy-optimized. Heat is supplied by a 13 kW wood-burning stove, which is fueled by wood from the property's own forest. In addition, a photovoltaic system has been installed, which maximizes self-consumption and makes intelligent use of surplus electricity by storing it in Cowa COMPACT Cells. This energy can then be used in the form of heat or hot water exactly when it is needed.
- Lithen project, Altstätten (SG)
- 2x Cowa COMPACT Cell SH 48 for buffering heating energy
- 1x Cowa COMPACT Cell DHW 58 for hot water production
- Energy source: Wood-burning stove with an output of 13 kW
- The system is combined with an intelligent electric heating element from Elwa, which uses surplus PV electricity to charge the cells.
Special features
The combination of wood heating, photovoltaics, and the compact Cowa COMPACT Cells creates a sophisticated, resource-saving energy system. The Elwa heating rod ensures that excess solar power is automatically fed into the heat storage tanks without any grid feed-in.
The Cowa COMPACT Cells play a central role in this system:
Thanks to our phase change material, they store thermal energy as needed, are maintenance-free, and require significantly less space than conventional water-based thermal storage tanks. This allows optimal use of limited space.
The renovated building is now virtually energy self-sufficient. Heating, hot water, PV system, and storage technology are intelligently networked and make optimal use of the available energy.
The result: cost and energy savings, compact, efficient, sustainable, and CO₂-neutral.
Implementation
This project was implemented by JenneRgie GmbH. Many thanks to our local partner.
