Viessmann supplier in Romania
Industrial boilers and heating systems for production
Founded in 1917 · Headquarters: Allendorf (Eder), Germany
Who is Viessmann and what does it make?
Viessmann is a German manufacturer of heating equipment, founded in 1917 in Hof an der Saale and later moved to Allendorf (Eder), where the group still has one of its production centres. The industrial range includes Vitomax HW high-pressure hot water boilers, Vitomax LW low-pressure hot water boilers and Vitomax HS high-pressure steam generators, alongside cogeneration units for the simultaneous production of electricity and heat. For industrial installations in Romania we can quote boilers and cogeneration modules from this range, configured to the power and fuel the project requires.
What sets the Vitomax range apart is its range of outputs and its readiness for hydrogen: the HW series covers 0.35-20 MW, the LW series goes up to 22 MW, and the HS steam series delivers 0.5-31.5 tonnes of steam per hour, all with stated efficiencies above 95.5% and the capability to run on 100% hydrogen or alternative fuels.
For Romanian plants with a continuous process — chemicals, the chlorine industry, industries with high steam or hot water consumption — the Vitomax range suits the retrofit of old boiler houses, especially where the investment must leave room for a later switch to lower-emission fuels.
What do we supply from the Viessmann range?
| Product | Description |
|---|---|
| Vitomax HW high-pressure hot water boiler | Industrial hot water boiler with a flow temperature above 110°C, with an output between 0.35 and 20 MW, stated efficiency above 95.5% and the capability to run on 100% hydrogen. Used for heating industrial processes and district heating networks at large sites. The customer must tell us the heat output required, the flow/return temperature wanted and the fuel available on site. |
| Vitomax LW low-pressure hot water boiler | Industrial hot water boiler for lower working pressures than the HW series, with an output between 0.65 and 22 MW, efficiency above 95.5% and an option to run on hydrogen or alternative fuels. Typical application: heating of industrial halls and processes with moderate temperature requirements. The customer must state the output required and the working pressure of the existing circuit. |
| Vitomax HS high-pressure steam generator | Steam boiler for industrial processes with flows between 0.5 and 31.5 tonnes of steam per hour, efficiency above 95.5% and multiple fuel options, including hydrogen readiness. Used in industries with high process steam consumption, such as chemicals or chlorine production. The customer must indicate the steam flow required, the pressure required and the type of fuel available. |
| Cogeneration units for electricity and heat | Cogeneration modules that produce electricity and heat simultaneously from a single fuel, with a higher overall efficiency than producing the two forms of energy separately. They are sized on the plant's simultaneous electrical and heat consumption. The customer must provide the hourly electrical and heat consumption profile so that the unit is sized correctly. |

How do we supply Viessmann in Romania?
We hold no stock of our own of Viessmann boilers — we bring them in to order through EU supply channels, usually within 1–4 weeks of order confirmation, which applies to units configured for a project. For a correct quotation we need the heat output required, the type of fuel available on site and whether the current installation runs on hot water or steam. The information on the Vitomax range comes from the manufacturer's documentation; for a retrofit project we recommend a technical discussion beforehand, because correct sizing depends on the plant's real consumption profile, not only on the currently installed output.
Lead times for units specially configured for a project are set for each request; installations commissioned by another supplier remain outside our quotation.
Frequently asked questions about Viessmann
What does the code B2HE or B2KE at the end of a Viessmann boiler name mean?
The suffixes B2HE and B2KE at the end of the Vitodens 200-W name indicate the construction variant of the boiler, not a separate accessory: B2HE is a heating-only boiler, and B2KE is a combi type, with domestic hot water. The full code must be read together with the base series.
What is the difference between the Vitocrossal 200 and Vitocrossal 300 series from Viessmann?
The output ranges differ from model to model: for example Vitocrossal 200 CIB covers 80-318 kW, while Vitocrossal 300 CR3B covers 787-1400 kW; the exact values are published in the data sheets of each model.
What details are useful when requesting a quotation for a Viessmann boiler?
For a correct estimate we need the heat output required, the type of fuel available and the intended use of the installation, residential or industrial. On the basis of these data we can indicate the suitable series from the Vitodens, Vitocrossal or Vitomax range, with the final quotation to be confirmed after consulting the manufacturer's public technical documentation.
Do you supply Viessmann equipment in Romania?
For Viessmann equipment we work to order only, usually in 1–4 weeks, set after the chosen series is confirmed; we do not keep this range on the shelf, given the many outputs and configurations published by the manufacturer.
What is a Vitocell series cylinder and how do I choose the right model?
A Vitocell cylinder is a tank for domestic hot water, available in enamelled versions or with a single or double coil, such as model 100-B; model 100-E is a heating water buffer tank. The choice depends on the volume needed in the household, the type of heat source it will be coupled to and the space available for installation.
How do I request a Viessmann quotation?
Send the Viessmann code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
