The HONEYWELL vxt-24 is an electronic digital water feeder designed for low-pressure steam and hot water boiler systems. Operating at 24 volts, this programmable unit automatically feeds makeup water to maintain proper system water levels, protecting the boiler from low-water conditions. A built-in feed counter tracks the number of feed cycles, giving technicians a clear record of system water loss over time. This data helps identify leaks or other issues before they become costly failures. Licensed boiler technicians and hydronic heating contractors install this control as part of a complete boiler safety and maintenance strategy.
The vxt-24 is well suited for residential and light commercial hydronic heating systems where automatic water makeup is required. Its 24-volt programmable design integrates with standard boiler control wiring, making it a practical replacement or upgrade for conventional float-type water feeders. The feed counter feature is especially useful in service environments where tracking water consumption between maintenance visits is part of a routine inspection protocol.
Designed as an OEM-style replacement or upgrade water feeder for residential and light commercial low-pressure steam and hot water boiler systems requiring 24-volt automatic water makeup control.
Installation should be performed by a licensed boiler technician or qualified hydronic heating contractor. Shut off boiler power and allow the system to cool before beginning any work on water supply or control wiring. Follow applicable local plumbing and mechanical codes, including ASME and IFGC guidelines where applicable. Verify system operating pressure is within the rated range of the feeder before returning the boiler to service.
