Viessmann Vitotron 100 1.0 - 24.0 kW + 100l Cylinder
Code: Z021176Related products
Product detailed description
- compact electric boiler, with an integrated expansion vessel with a volume of 5 l
The system contains an electric heat source with heating circuit control, a pump and an expansion vessel. Two output levels are available, 8 kW and 24 kW. The Vitotron 100 is available in two versions: one with weather-compensated control or as constant-temperature control.
Using solid fuels is currently the cheapest option, but it is not convenient. With a fireplace or a solid fuel boiler, you must not forget to regularly add fuel and clean the appliances. Another disadvantage in terms of comfort is that the boiler room cannot be left unattended, and during longer absences, such as a holiday, there is a risk of the system freezing.
These problems disappear when using an electric boiler, which supports heating when, for various reasons, it is not possible to add fuel. It switches on fully automatically only when, for example, the fire in the fireplace goes out in the morning. When nobody is home, it will maintain only a temperature that prevents freezing.
Convenient operation and easy installation
Installation of the Vitotron 100 boiler is inexpensive and does not require a gas line connection, a chimney, a boiler room or fuel storage space - only an electrical connection is needed. The use of weather-compensated control (type VMN3) ensures high thermal comfort and maintenance-free operation, which, combined with a boiler efficiency of 99.4%, ensures energy-efficient operation.

Trouble-free cooperation
Electric boilers are also often used to support the heating of buildings where the primary heat source is, for example, a heat pump, a fireplace or a solid fuel boiler. In this way, they combine the use of renewable sources with comfort of use and ensure a temperature above freezing when users are not at home. These are small appliances with an elegant design that can be installed practically anywhere.
When suitable modules are used, the boilers can cooperate with a buffer tank of the heating system. Heat accumulation during low-tariff periods reduces heating costs.
The Vitotron 100 can cooperate with any heating system and a DHW storage water heater. It is equipped with a 5 l expansion vessel and the necessary safety fittings. When it cooperates with a DHW storage water heater, it is possible to regulate the water temperature and control the circulation pump according to daily or weekly settings.

Frequently asked questions
- How do I choose the correct output for a Viessmann electric boiler? Just as with gas boilers, base your choice on the calculated heat loss of the heated building. With electric boilers, it is additionally crucial to check whether the capacity of your electrical connection to the house (flat) allows it - higher outputs (from around 12 kW upwards) usually require a three-phase 400 V connection and a correspondingly sized main circuit breaker, which will be confirmed by a revision technician or directly by your electricity distributor.
- Is an electric boiler worth it compared to a gas boiler or a solid fuel boiler? An electric boiler has the lowest purchase price and the simplest installation (no need for flue gas extraction, since it does not burn anything), but the operating costs for electricity are usually higher than for gas or wood/coal for the same amount of heat delivered. It is particularly suitable where gas is not available, as a supplementary/backup source, or for a building with low consumption (well-insulated new builds, cottages, flats).
- How does an electric boiler regulate output? Most models gradually switch individual heating elements on/off (in steps), while some more modern models also allow smoother output modulation - this affects the smoothness of heating and, to some extent, the lifespan of the switching elements.
- Can I install this electric boiler myself? Connection to the electrical grid, revision and commissioning must be carried out by a person with electrotechnical qualification in accordance with the applicable standard STN 33 2000 and related regulations - self-installation is not permitted, either in terms of warranty or safety.
- Can this electric boiler also heat domestic hot water? With many models, yes, usually in combination with a separate hot water cylinder and a switching (3-way) valve that switches between the heating circuit and heating the cylinder - the exact option and required accessories for this specific model can be found in the technical parameters above, or you can consult our customer service.
This particular Viessmann model has an output of 1.0 - 24.0 kW - as a guide, this corresponds to a significantly higher electric current (with a three-phase connection) than you might expect from a common household appliance, so it is necessary to check the capacity of your house's main circuit breaker and connection in advance.
