Vitomax HS-EH, high security of supply through the use of electric cartridge heaters
The new Viessmann Vitomax HS-EH hybrid boiler combines the proven fired shell boiler with additional electric flange heater.
Electric steam generation via this hybrid boiler offers multiple benefits. The focus here is on clean, energy saving provision of energy. Equally important is its high operational reliability and availability. Smooth operation is guaranteed. We offer components designed to work together and therefore economical and futureproof system solutions for industrial applications.
What characterises the Vitomax HS-EH hybrid boiler?
These hybrid boilers use excess electricity to generate steam, thereby reducing the use of conventional fuels. This not only ensures increased climate friendliness but also operational reliability and cost saving operation.
The Viessmann Vitomax HS-EH hybrid boiler scores with higher efficiency than comparable models that only use fossil fuels. In this way, it is also possible to save on fossil fuels. This reduces the overall operating costs. It also conserves valuable, finite resources. Basically, the running costs are lower because the hybrid boiler uses cheap electricity. This can be night electricity but also self-generated electricity excess. Electrical assistance in generating steam also has the benefit of reducing flue gas emissions of carbon oxides and nitrogen oxides (COx and NOx). This in turn means that fewer emissions charges have to be paid by the company. Another benefit of using electrical energy is the high security of supply. If fossil energy sources fail, the hybrid boiler is able to bridge this proportionally. Interruptions in processes can thus be minimised.
The start-up process can be optimised through using electricity. This prevents the flue gas from falling below the dew point. After the operating status has been reached, the boiler switches over or on to the primary fuel or this is switched on. This means that fuels whose flue gas dew points are low or whose condensate components would be harmful can also be used. Like all Viessmann shell boilers, the Vitomax HS-EH hybrid boilers are H2-ready and enable the proportional use of hydrogen.
In addition, the use of hybrid boilers allows peak loads to be balanced out. The normal range is also increased. This means that a better supply can be ensured during partial load decreases.
Finally, electric heat retention offers some benefits during use. Not only does it enable rapid availability of thermal energy, it also avoids unnecessary burner cycling. This in turn reduces wear and tear, thus saving costs.
Power consumption in the hybrid boiler
In order to enable sensible use of the electricity, up to two heating cartridges are installed in the Vitomax HS-EH hybrid boiler. These are "flange heaters" and are connected to the boiler via a connector. They are characterised by high resistance to corrosion and mechanical stress. Depending on the version, the immersion length of the heating cartridges is up to 4.5 metres.
Significance for the energy transition
If you choose a Viessmann hybrid boiler, you will be contributing to the energy transition. This system uses the "power-to-heat" principle to a certain extent and uses electricity to generate steam. In this way, either self-generated electricity excesses or production peaks from the electricity grid can be used in an ecologically and economically sensible way. This reduces the use of fossil fuels. Electricity from wind and solar energy causes no emissions. In this way, the hybrid boiler allows you to take a more climate-friendly and at the same time futureproof approach. It is also a further step towards not exceeding the Paris Agreement's limit of a maximum of 1.5 degrees Celsius of global warming.
