Optimally matched system technology

Large-scale systems for industrial, commercial, and municipal applications must provide clean and energy-efficient energy. High operational reliability and availability are essential. Viessmann offers precisely these efficient energy systems – in the form of all-electric boilers. Our portfolio includes components and systems designed to work together, ensuring you receive a cost-effective and future-proof solution. The following options are available:

Automation and control technology
Control and measuring instruments and control technology
Fuel fed combustion systems
Water treatment systems and analysis
Feedwater tank and other thermal reservoirs
Heat recovery systems
Pipelines and smoke systems

Less costs

Another benefit for your company: you’ll pay lower emissions fees because using electricity on-site eliminates the need for _COx and _NOx flue gas emissions . Additional costs can be saved because fuel storage and a flue system are no longer required. This also reduces the footprint and weight compared to conventional boilers. Your operating costs are also lower because you can use cheaper electricity tariffs or even your own excess electricity.

Features and specifications

The Vitomax HW-E utilizes excess electricity, enabling it to utilize peak power generation in an environmentally and cost-effective manner. The heating cartridge converts the electricity into heat, which is then used to generate hot water. The heating cartridge is attached to the boiler via a connector and complies with current DIN standards. Wall thicknesses of up to 2.1 millimeters ensure high resistance to corrosion and mechanical stress. Depending on customer requirements, heating cartridge immersion lengths of up to 4.5 meters are available.

Technical specifications of the Vitomax HW-E

In addition, the Viessmann Vitomax HW-E electric boiler is characterized by high power and high efficiency.

Capacity: 0.5 – 5.0 t/h / 0.45 – 4.5 MW
Permissible working pressure: from 6 to 25 bar

Significance for the energy transition

An electric boiler for industrial use allows you to take a step toward energy transition. This system utilizes the power-to-heat principle, using electricity to generate steam and heat. The growing share of renewable energy sources, especially wind and solar, in the electricity grid can be efficiently utilized in this way.

This already puts you on a more climate-friendly path and guarantees a future systemic solution. The Paris Agreement clearly states that global warming must not exceed 1.5 degrees Celsius. This goal can only be achieved if private and public investment contributes to its implementation.
