VoltMax Electric Boiler – Precision Heating for Commercial and Industrial Hydronic Systems

High-Efficiency Electric Boiler With Advanced Smart Control Technology

The VoltMax series of commercial electric boilers is engineered to deliver high-performance hydronic heating for commercial, institutional, and industrial applications. Designed with maximum energy efficiency, modular power management, and easy integration, VoltMax is the ideal solution for buildings requiring precise temperature control and clean, quiet electric operation.

With output capacities ranging from 22.5 kW to 400 kW, VoltMax is available in multiple single-phase and three-phase voltage options to accommodate diverse electrical infrastructures.


🔧 Smart Heating with Advanced SCR Power Modulation

The VoltMax controller uses a solid-state SCR relay to modulate boiler output from 0–100% based on demand. This real-time kW management system provides:

  • Smooth power ramp-up and down, reducing stress on relays

  • Precise temperature regulation

  • Avoidance of energy spikes and peak usage charges

  • Lower operational costs with consistent comfort delivery


🧠 Intelligent Digital Control Interface

VoltMax features an intuitive electronic controller with a large backlit display for simplified monitoring and setup. Through the integrated user interface, operators can access and adjust key performance metrics and settings such as:

  • Setpoint temperature & real-time outlet temperature

  • Heating demand & stage status

  • Outdoor temperature via sensor

  • Power modulation percentage

  • Operating pressure and energy mode (electric/auxiliary/dual-energy)

  • Boost mode activation

  • WWSD (Warm Weather Shut Down)

  • Audible/visual alarms with status lights (green/yellow/red)

  • Temperature in °F/°C and multilingual support (English/French)


🌡️ Flexible Temperature and Power Control Options

VoltMax supports a wide range of automated and remote heating control modes:

  • Fixed or modulating water temperature via outdoor sensor

  • Integration with BACnet IP or MSTP controllers for building automation

  • Power and temperature control via 0-10 VDC signal

  • Schedule-based operation tied to occupancy patterns

  • Remote monitoring, setting adjustments, and alarm email notifications via Ethernet


🔄 Dual-Energy and Auxiliary Boiler Integration

For facilities with backup boilers or hybrid systems, VoltMax can:

  • Seamlessly switch between electric and auxiliary energy sources

  • Prioritize domestic hot water or heating loops

  • Lower temperature when buildings are unoccupied via external contact signal

  • Operate silently and only when needed to further optimize energy use


🔩 Robust Design & Easy Maintenance

Built for long-term reliability and minimal upkeep, VoltMax features:

  • Compact vertical design to save mechanical room space

  • Easily replaceable immersion-type Incoloy heating elements

  • Low and high-voltage fuse protection

  • Manual & automatic high-limit safety resets

  • ASME-certified safety valve

  • Low-water cut-off with test/reset button

  • 3” high-efficiency insulation


🔍 Monitoring & Diagnostics

  • Real-time amperage tracking to detect anomalies and monitor power consumption

  • Boiler flow and return temperature sensors

  • Dry contacts for alarm signals and pump control

  • Integration-ready with external systems for full HVAC compatibility


Key Features at a Glance

  • Output Range: 22.5 kW to 400 kW

  • Temperature Range: 50°F to 200°F (10°C to 93°C)

  • 100% energy-efficient operation

  • Compatible with auxiliary boilers for dual-energy systems

  • Operates silently and cleanly – zero emissions

  • Perfect for commercial buildings, schools, hospitals, and multi-unit properties


The VoltMax commercial electric boiler is your smart, scalable, and sustainable heating solution. Whether used as a primary heat source or auxiliary backup, it delivers unmatched precision, flexibility, and control — all while reducing energy waste and maintenance.
