Keep Boilers Running Smoothly

Water feeders are vital to keeping boiler systems safe and efficient. They help maintain proper water levels, preventing damage caused by dry operation or overheating.

Simplify Maintenance with Automatic Water Feeders

An automatic water feeder for boilers eliminates the guesswork. It refills the system when water drops too low, so you don’t have to monitor it manually.

Why Choose a Water Feeder for Boiler Use?

Using a water feeder for boiler setups ensures the system stays properly pressurized and balanced. It helps avoid performance issues and extends the life of your equipment.

Steam Boiler? Go Automatic

A steam boiler automatic water feeder is designed to keep up with demanding conditions. It supports consistent steam output and reduces wear by avoiding dry-firing risks.

Signs It’s Time to Replace

If your boiler frequently shuts off or loses pressure, your water feeder may not be doing its job. A quick replacement can restore efficiency and safety.

Frequently Asked Questions

  • Manual feeders offer simplicity and control for homeowners who check their boiler regularly.
  • Automatic feeders are key for commercial setups or homes with unattended boilers. They add water when needed, and advanced models log water use, helping detect leaks or system issues early.

Yes - rare failures in the LWCO or electrical glitches (like brownouts) can lead to unwanted water feeding. This can flood the system or radiators, causing serious water damage .
Solution: Use feeders with lockout features, feed counters, or install an interrupter switch to stop flooding before escalating.

Automatic feeders monitor the LWCO. When the LWCO detects low water, it sends a signal to the feeder to add water, then stops once the level is restored—usually via a float or probe system.

  • Compatibility with 24 VAC or 120 VAC systems.
  • Feed counters to track water added.
  • Programmable delays to allow proper condensate return.
  • Lockout protection after consecutive feeds.
  • Manual feed button and adjustable feed volume.

Check it regularly to:

  • Ensure proper operation during heating cycles.
  • Monitor feed counts (excessive feeding may mean leaks or LWCO issues).
  • Clean strainers and inspect for mineral buildup.

Common issues include:

  • Malfunctioning LWCO that constantly signals for water.
  • Boiler or return-line leaks.
  • Electrical faults or stuck float mechanisms.
