Product detailed description
- weather-compensated control
The system contains an electric heat source with heating circuit control, a pump and an expansion tank. Two power levels are available, 8 kW and 24 kW. The Vitotron 100 is available in two versions: one with weather-compensated control or as a 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 a longer absence, 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 top up 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 boiler is inexpensive and does not require a gas connection, a chimney, a boiler room or fuel storage space - all you need is an electricity connection. Using the 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 ease of use and keep the temperature above freezing when users are not at home. These are small appliances with a neat design that can be installed practically anywhere.
When used with suitable modules, the boilers can work together with the heating system's storage tank. Storing heat during low-tariff periods reduces 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 tank 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.

1. Modulated heating elements
2. Control for constant-temperature operation (VLN3) or for weather-compensated operation (VMN3)
3. High-efficiency circulation pump
4. Safety valve
5. Temperature fuse
6. Minimum pressure sensor

Frequently Asked Questions
- How do I check that the "Viessmann Vitotron 100 0.4 - 8.0 kW; with 3-way switching valve, tank sensor" fits my exact appliance? The most reliable way is to compare the exact type/catalogue designation on your appliance's (boiler, tank, water heater) rating plate with the compatibility stated directly in this product's name (Viessmann brand) and in its technical parameters above. If in doubt, send us the exact type designation of your appliance (including any serial number if available) - we will gladly verify compatibility for you.
- Why is it important to use an original/compatible part rather than a universal replacement? Parts such as seals, sensors or safety components (safety valves, thermal fuses) are usually dimensioned exactly to the parameters of the specific appliance (pressure, temperature, sensor's electrical resistance) - an incorrect part can cause reduced function, leaks, or, in the case of safety components, a real safety risk.
- Must this part be installed by a professional? For simpler, mechanical parts (e.g. gaskets, covers, small accessories not connected to electricity, gas or the pressurised part) a handy DIY person can usually manage the replacement after disconnecting the appliance from power and the pipework. However, for any intervention in the gas, electrical or pressurised part of the appliance (e.g. sensors located directly in the combustion chamber, safety valves, electrical modules) we always recommend a service technician - especially if the intervention could affect the validity of the warranty on the whole appliance.
- How do I know this part is worn and needs replacing? Common symptoms include visible wear/cracking (for seals and rubber parts), a leak of water or flue gases at the location of the part, an error message on the control display (for sensors and electronic modules), or an obviously reduced function of the appliance (e.g. irregular combustion for burner parts). If in doubt, it is safest to have the condition assessed by a service technician during the regular annual inspection.
- Is it worth keeping this part at home as a spare/service item? For parts that are subject to regular wear (seals, fuses, small mechanical parts) and whose failure would mean an outage of heating or water heating, keeping a spare is a sensible precaution - especially for an older appliance for which the part may be harder to source quickly.
