Water heater VTS Volcano VR2 (MPN 1-4-0101-0447) — VTS Volcano VR2 water-fired heater

VTS Volcano VR2 is a water-fired heater designed to deliver warm air to commercial and industrial interiors by connecting to a building’s hot-water heating circuit. The unit integrates a water-to-air heat exchanger and one or more built-in fans to transfer heat from the central heating system to the supply air stream. Engineered for integration with existing boilers and circulation systems, the VTS Volcano VR2 supports continuous or intermittent operation to maintain required indoor temperatures and assist ventilation needs.

Advantages

The VTS Volcano VR2 provides efficient space heating through direct exchange between hot water and supply air, reducing the need for separate electric heaters. Its compact cabinet and fan-assisted design ensure quick air delivery and even temperature distribution. Designed for compatibility with standard central heating circuits, the unit allows straightforward hydraulic and electrical connections and can be installed horizontally or vertically depending on building layout and ducting requirements.

Suitable for

• Heating of commercial premises such as retail spaces, offices, and warehouses
• Industrial halls and workshops requiring supplemental warm-air delivery
• Integration with existing hot-water boiler systems for centralized heating and ventilation
• Applications where rapid warm-air distribution and controlled ventilation are needed

Key specifications

• Heat transfer method: water-to-air heat exchanger with forced-air circulation
• Mounting options: compatible with horizontal or vertical installation and duct connections
• Air delivery: fan-assisted supply for controlled airflow and distribution
• Hydraulic connection: connects to building hot-water circuit and circulation pump
• Control compatibility: suitable for integration with standard thermostat and building controls

How to use

Install the VTS Volcano VR2 in the area to be heated and connect the heat exchanger to the building’s hot-water supply and return lines following local regulations and hydraulic design practices. Connect the electrical supply for the fans and control interfaces to the building control system or a local thermostat. Set desired temperature and fan speed via the control system; the unit will circulate warm air when hot water is present in the heat exchanger. Regular inspection of hydraulic connections, filters and fan operation is recommended to maintain performance.

Usage recommendations

Ensure the hot-water system is balanced and provides appropriate flow and temperature for the heater’s rated performance. When integrating with an existing boiler, verify compatibility of operating temperatures and install necessary mixing or safety valves. Schedule periodic maintenance including checking fan motors, air filters and heat exchanger cleanliness to sustain heat transfer efficiency and reliable operation.
