Industrial Hot Water Boilers: Efficient Process Heat with Zero Emissions

If you need to provide heat not just on an ad hoc basis, but continuously and reliably, our hot water boilers are the solution. As high-performance electric boilers for industrial use, they ensure that large volumes of water are reliably heated to the desired temperature—emission-free and highly efficient.

An industrial hot water generator differs significantly from standard boilers or household instantaneous water heaters. It is designed for centralized, continuous heat generation in large-scale industrial plants and, depending on requirements, is also suitable for use in potentially explosive atmospheres.

Hot water generators are used in a wide range of applications. In industry, for example, they are used to supply process heat where a constant supply of hot water is required for production processes. Hot water generators also play a central role in district heating systems, as they can generate large amounts of heat and transport it over long distances to consumers. Furthermore, they are essential for building services, such as heating large industrial properties or supplying hot water to sanitary facilities.

When selecting a suitable hot water heater, several important criteria must be considered. These include, above all, the unit’s capacity—that is, the amount of thermal energy it can generate—as well as the maximum pressure and the achievable water temperature. In addition, efficiency plays a crucial role, as an efficient hot water heater not only reduces operating costs but also operates in an environmentally friendly manner. All these factors must be carefully tailored to the specific application to ensure optimal functionality and cost-effectiveness.

Why Use Electric Hot Water Boilers in Industry?

Electric hot water generators offer significant advantages over oil- or gas-fired units. While traditional boilers rely on combustion technologies, industrial electric boilers operate entirely on electricity.

All that is needed for the process is electrical energy—no fossil fuels, no chimney systems, and no fuel logistics.

Your benefits at a glance:

Zero emissions

No combustion means no on-site CO₂ emissions. Ideal for meeting your ESG requirements and sustainability goals.

Compact design

Its small footprint allows for easy integration into existing control cabinet and system configurations.

Low-maintenance

Since there are no burners or exhaust systems, maintenance costs are significantly reduced.

Versatile applications

Suitable for use in a variety of technical systems

Precise control: 

Fast response times and continuous power adjustment for exact process temperatures.

Maximum efficiency

The efficiency rate exceeds 99%, as the energy is converted directly into heat in the water with virtually no loss.

The Role in the Power-to-Heat Concept

The industrial hot water boiler is a key component of the energy transition. It integrates seamlessly into Power-to-Heat (PtH) concepts: Use excess electricity from renewable energy sources (e.g., during grid overloads) to generate heat for your processes. Thanks to their flexible load absorption, our systems actively contribute to grid stabilization and make your production independent of volatile gas prices.

WVN Series Hot Water Heaters – Technical Excellence

The WVN model is our specialist for high-performance applications. This hot-water boiler was specifically designed for direct integration into industrial district heating networks and large-scale industrial processes.

Eigenschaften & Highlight

  • High-performance: Available in the range of 1 to 10 MW.
  • Stepless control: Precise power consumption, combined with specialized switchgear for high loads.
  • High operational reliability: Unattended operation (BoB 72h) in accordance with EN 12953 is possible.
  • No special water requirements: Tolerant of varying water qualities.
  • Redundancy: Maximum reliability thanks to a large number of individual, independently operating tubular heating elements.
  • Direct connection: Can be integrated directly into the system without a separate heat exchanger, which reduces investment costs.

Cost-Effectiveness and Certification

An industrial electric boiler offers low capital costs (CAPEX) and—when using self-generated electricity or taking advantage of low grid rates—attractive operating costs (OPEX). We can assist you in planning CO₂-reduction measures for process heat.

Investing in electric hot water boilers pays off in the long term thanks to low operating costs and minimal maintenance requirements. With an efficiency rating of over 99%, virtually all of the electrical energy used is converted into usable heat, which significantly reduces energy costs. In addition, flexible operating hours and easy integration into existing systems enable demand-driven heat supply, which conserves resources and minimizes downtime. Subsidy programs for energy-efficient technologies further support cost-effectiveness and make the use of modern hot water generators a future-proof investment for sustainable industrial processes.
