Description
The Hydrolevel EW222 is a 1/2″ NPT Extended Electro-Well designed specifically for use with tankless coil burner applications. Featuring a long nut for secure installation, this electro-well serves as the sensing element that activates the Low Water Cut-Off (LWCO) function on compatible Hydrostat Controllers, helping to protect boilers from dangerous low-water conditions.
Engineered for reliable performance in hydronic heating systems, the EW222 provides accurate water level detection, ensuring that the Hydrostat Controller can respond quickly to low-water situations and shut down the burner before damage occurs. Its extended design allows for proper immersion depth in tankless coil boiler configurations where standard wells may not reach the required sensing zone.
