Low water cut-offs are a necessary safety feature in all boiler installations. Low water cut-offs are small sensors that constantly read the level of water in your boiler; if the water falls below the manufacturer's designated safety level, the low water cut-off will shut down a boiler and notify the owner. We offer Hydrolevel low water cut-offs, one of the most reliable brands in the industry.
