4567 Water Feeder 24 VAC for Steam Boilers
The 4567 Water Feeder is a 24 VAC unit designed for steam boiler makeup water. It is best for users who already have a 24 VAC control circuit and want a direct replacement that integrates with existing boiler control boards. This feeder is suitable for light to moderate domestic or small commercial steam systems that require steady makeup water. Caution: verify compatibility with your existing low-water cutoff and wiring before installation to avoid control mismatches.
1/2″ Boiler Feed Water Regulator For Watts S1156F
This bronze regulator maintains consistent boiler water pressure and provides automatic makeup to compensate for leaks or losses. It includes a union inlet, NPT outlet, a tight-seating check valve, a stainless steel strainer, and a manual purge lever, making it a robust choice for both residential and commercial hydronic heating systems. Best for: installations requiring durable bronze construction and a full feature set for reliable backflow prevention. Caution: ensure proper sizing for your boiler’s pressure range (10-25 PSI).
VXT120 Automatic Steam Boiler Water Feeder
The VXT120 is designed for universal compatibility with probe and float-type low-water cut-offs. Its programmable feed delay helps prevent flooding, and it includes lockout flood protection. Best for: steam boilers that require flexible integration with existing cut-off systems. Caution: this unit’s behavior depends on your current low-water cutoff configuration; confirm compatibility before purchase.
24V Water Feeder
The 24V Water Feeder from Miller emphasizes ease of wiring and straightforward operation for 24V control systems. Best for: homeowners or service technicians who want a simple, reliable 24V option for boiler makeup water. Caution: confirm the feeder’s compatibility with your boiler’s pressure and rise requirements before installation.
1/2″ Boiler Pressure Regulator / Regulator for 1156F
This regulator serves as a replacement option for 1156F, B1156F and S1156F units. Best for: users upgrading or replacing older regulators within a similar sizing and flow range. Caution: verify exact compatibility with your system’s governor settings and piping layout to ensure correct operation.
Buying Guide: Key Considerations For Selecting A Boiler Water Feeder
- System type and compatibility: Choose a feeder that matches your boiler type (steam vs. hydronic) and integrates with your low-water cutoff or control circuit.
- Control voltage: Decide between 24V or other control voltages based on your system wiring and relay compatibility.
- Materials and durability: Bronze regulators offer corrosion resistance in demanding environments; ensure the unit is suitable for continuous operation.
- Automatic makeup and protection: Look for features like programmable feed delays and flood protection to prevent overfilling.
- Pressure and sizing: Confirm the regulator or feeder’s pressure range aligns with your boiler’s operating pressure (often in the 10-25 PSI range for residential systems).
- Installation considerations: Check for included accessories (check valve, strainer, purge lever) and whether the unit requires professional wiring or service.
Frequently Asked Questions
- What is a boiler water feeder used for?
A boiler water feeder automatically adds make-up water to maintain the correct boiler level and pressure, compensating for system losses or leaks.
- Which feeder is best for steam boilers?
Feeder units designed for steam boilers with universal compatibility, like the VXT120, are strong choices due to their integration with low-water cut-offs and flood protection.
- Do I need a 24V feeder or a different control voltage?
Choose 24V if your system uses 24V controls; otherwise, align the feeder’s control voltage with your boiler’s wiring and relay setup.
- Is bronze construction important for boiler feeders?
Bronze offers durability and corrosion resistance in boiler feed lines, which is important for long-term reliability in harsh water conditions.
- Can I replace an older regulator with a newer model?
Yes, but verify compatibility with existing piping, inlet/outlet connections, and the regulator’s pressure range to ensure proper operation.
