Water Fan Heater VTS Volcano VR3 EC (model 1-4-0101-0444)

VTS Volcano VR3 EC is a water-powered fan heater designed to provide reliable space heating by using hot water as the primary heat source. The unit integrates an electronically commutated (EC) motor to drive the fan, offering efficient air circulation and controllable performance. Designed for commercial and industrial environments, this heater delivers fan-assisted convection to distribute warm air evenly across large indoor areas such as warehouses, workshops and production halls.

Advantages

The EC motor enables precise fan speed control with reduced electrical consumption and lower acoustic emission compared with traditional motors. The heat exchanger and water connection layout are optimized for efficient thermal transfer and straightforward integration into existing hydronic systems. Compact construction and durable casing materials support long-term operation in demanding indoor settings while enabling easier maintenance access.

Suitable for

• Heating of large indoor commercial spaces (warehouses, logistics centres)
• Workshops, production halls and service facilities
• Seasonal heating in facilities with a central hot-water system
• Supplementary heating in areas where fan-assisted convection improves temperature distribution

Key specifications

• Heat source: hot water (hydronic)
• Air movement: fan driven by EC motor for adjustable airflow
• Intended application: commercial and industrial space heating
• Mounting options: wall or ceiling installation suitable for large indoor spaces
• Construction: corrosion-resistant casing and service access panels
• Control capability: variable fan speed and compatibility with building controls for regulated output

How to use

Connect the unit to the facility hot-water circuit according to the hydronic layout and local plumbing standards, ensuring correct flow direction through the heater coil. Electrically connect the EC fan motor and control interfaces to the building control system or a dedicated controller to set desired airflow and operational schedules. Commission the heater by verifying hydraulic tightness, bleed air from the heat exchanger, and perform initial electrical and functional checks to confirm fan operation and temperature rise across the unit.

Usage recommendations

For optimal performance, ensure the water quality and pressure match site specifications and include appropriate strainers and isolation valves for maintenance. Regular visual inspections and scheduled servicing of the heat exchanger, fan and electrical connections will sustain efficiency and prolong service life. Use the EC motor’s variable-speed control or building automation to balance comfort and energy usage, and follow local codes for installation and safety.
