Watts 0386422 Regulator Els PW 17895 this means a drop-in installation

this means a drop-in installation with high-corrosion-resistant terminals and a calibrated diaphragm that maintains accuracy under fluctuating thermal conditions

System Reliability: Prevents short-cycling and thermal stress on the heat exchanger by maintaining strict temperature differentials during the heating cycle

this board provides the reliable timing and termination logic necessary to maintain system COP

The most common causes include restricted airflow resulting from dirty filters

Watts 0386422 Regulator Els PW 17895 this means a drop-in installationThe Watts 0386422, technically recognized as the SB1156F 1 2" Bronze Feed Water Pressure Regulator, is a high capacity solution engineered for hydronic heating systems. Built with a durable bronze valve body and a union solder inlet x NPT threaded outlet, this regulator is designed to automatically fill boiler piping and maintain a consistent system head. Optimized for hydronic boiler feed applications, it features an adjustable pressure range of 10
