Low maintenance and perfect for small vacation homes and additions

Automatic outdoor temperature sensor and warm weather shutdown can be used to keep remote locations warm without using excess energy. The Vitotron 100 switches on when the temperature falls below an individually set minimum temperature, allowing it to keep the room temperature in the comfort range.

Heat storage

The use of an electric boiler in conjunction with a hot water buffer tank ensures convenient and inexpensive heating with relatively low system costs. Vitotron 100 can be used as a backup to a heat pump or used to maintain a storage tank to take advantage of off-peak utility rates. It features an external shutdown input which can be used in conjunction with hybrid systems and utility home energy management systems.

Vitotron 100 is also a perfect partner for photovoltaic and as a backup to solar thermal systems. This allows the boiler to be operated even more cost-effectively, as priority is given to using the free, self-generated energy from the roof. The combination of heat storage and free energy from a photovoltaic system enables very low running costs.
