More About Water Feeders
Water feeders protect boilers by maintaining a safe water level. Low water cutoffs work in coordination with water feeders to detect the fluid level in hot water and steam boilers. If water level falls below the minimum safe operating level, the water feeder is initiated. Water feeders can be automatic (electric) or manually operated.
Electric water feeders eliminate the need to manually add water to the boiler. These water feeders are used for low pressure steam boilers with a cold water feed. Electric water feeders detect fluid, expose leaks, and provide the necessary information needed to diagnose a problem.
Mechanical water feeders are used for hot water and low pressure steam boilers with a cold water feed. Mechanical feeders contain a float which responds to the water level in a boiler. These units are quiet, durable and feature an isolated feed valve which minimizes lime and scale build-up.
We offer a wide selection of McDonnell & Miller, Taco and Hydrolevel water feeders for protection of all types of boilers, ranging from small residential hot water boilers to large industrial steam units.
