Viessmann Vitotron 100 1.0 - 24.0 kW
Code: Z020840Related products
Product detailed description
The system includes 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 fuel 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 drawback 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 the temperature needed to prevent freezing.
Comfortable operation and easy installation
Installing the Vitotron 100 is inexpensive and does not require a gas pipeline connection, a chimney, a boiler room or fuel storage space - all you need is an electrical connection. Using weather-compensated control (type VMN3) ensures a high level of 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 point when users are not at home. These are small appliances with a neat design that can be installed practically anywhere.
When suitable modules are used, the boilers can work together with the heating system's buffer tank. Storing heat during low-tariff periods ensures lower heating costs.
The Vitotron 100 can work with any heating system and domestic hot water storage tank. It is equipped with a 5 l expansion vessel and the necessary safety fittings. When working together with a domestic hot water storage tank, the water temperature can be regulated and the circulation pump controlled according to daily or weekly settings.

Frequently Asked Questions
- How do I choose the right 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 also essential to check whether the capacity of your electrical connection to the house (flat) allows it - higher outputs (from roughly 12 kW upward) usually require a three-phase 400 V connection and a correspondingly sized main circuit breaker, which your inspection technician or the electricity distributor can confirm for you.
- 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 flue is needed, since it burns nothing), but running costs for electricity are usually higher than for gas or wood/coal for the same amount of heat delivered. It is especially suitable where gas is not available, as a supplementary/backup source, or in a building with low consumption (well-insulated new builds, cottages, flats).
- How does an electric boiler regulate its output? Most models switch individual heating elements on/off in stages, while some more modern models also allow smoother power modulation - this affects the smoothness of heating and, to some extent, the lifespan of the switching components.
- Can I install this electric boiler myself? Connection to the electrical network, inspection, and commissioning must be carried out by a person with electrical qualifications in accordance with the applicable STN 33 2000 standard and related regulations - do-it-yourself installation is not permitted, either for warranty or safety reasons.
- Can this electric boiler also heat domestic hot water? With many models, yes, usually in combination with a separate hot water tank and a switching (3-way) valve that switches between the heating circuit and heating the tank - you can find the exact option and accessories needed for this specific model in the technical parameters above, or consult our customer service.
This specific Viessmann model has an output of 1.0 - 24.0 kW - as a guide, this corresponds to a noticeably higher electric current (with a three-phase connection) than you would expect from a typical household appliance, so it is necessary to check the capacity of your main circuit breaker and connection in advance.
