Hydrolevel VXT-24 Automatic Water Feeder – 24V Model for Steam Boiler Applications

The Hydrolevel VXT-24 (part number 45-026) is a 24V automatic water feeder designed for use with residential and light commercial steam boiler systems. It interfaces with both probe-type and float-type low water cut-offs to maintain proper boiler water levels and includes integrated digital diagnostics for service accuracy and troubleshooting support.

Unlike conventional feeders, the VXT-24 incorporates a digital counter to log all water fed into the system, enabling contractors to monitor system usage and identify signs of excessive water loss that may indicate leaks or failed components.

System Features

• Voltage Rating: 24 VAC
• Application: Steam boiler make-up water control
• Feed Volume Settings: Adjustable 1–5 gallons or “LWCO” setting
• Feed Delay Settings: Programmable from 30 seconds to 10 minutes
• Control Interface: Manual feed button and LED status indicators

Key Functional Capabilities

• Compatible with all common low water cut-off types (probe and float style)
• Feed delay function allows time for condensate return prior to initiating a cycle
• On-board counter tracks both automatic and manual water feed volumes
• Includes lockout feature to prevent overfill if burner does not restart after two feed attempts
• Secondary feed protection initiates an additional cycle if water level remains low after first fill

Installation Notes

Professional installation is recommended to ensure proper wiring, pipe sizing, and feed volume calibration. Installer must verify compatibility with the system’s existing LWCO configuration and confirm proper voltage. Install in accordance with manufacturer instructions and local mechanical codes.

Contractor Reference

The Hydrolevel VXT-24 is widely used in steam heating service and retrofit work where consistent water level management and diagnostic data are required. Its onboard digital tracking is especially useful in identifying excessive system makeup water, aiding in leak detection and preventative maintenance planning.
