Benefits Of Electric Boiler

Vitotron 100: Plug-and-play electric heating for residential homes

The Vitotron 100 is the easiest way to add hydronic space heating to new and existing residential systems, with a space saving design and integrated components for a fast and simple installation.

Aesthetically pleasing and easy to install

Installing the Vitotron 100 VLN2 electric boiler* does not require a gas connection, chimney or boiler room – a power source is all that is needed. The weather-compensated control unit utilizes an outdoor temperature sensor and heating curves, ensures effective control and adjusts the water temperature automatically according to the outside temperature.

Efficient and convenient

The heating curves and operating efficiencies up to 99.4 percent ensure energy savings over typical electric space heating.

With efficient operation and advanced controls, the Vitotron 100 simultaneously offers a high level of user comfort and is perfect for low-temperature heating applications in space-restrictive areas like closets and small mechanical rooms. Without venting and gas connections, the small plug-and-play devices can be installed practically anywhere.

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.
