Water Heater

Silicon Controlled Rectifiers (SCRs) are used in instant electric water heaters and industrial boilers to provide precise, infinitely variable power control to the heating elements. Unlike traditional relays that simply turn power on/off, SCRs (also known as thyristors) adjust the power flow, resulting in faster response times, extended heater life, and precise temperature regulation.SCR in Instant Tankless Water HeatersIn residential and commercial electric tankless water heaters (e.g., Titan-SCR2), SCRs manage power to ensure constant water temperature.How it Works: A microcontroller monitors inlet and outlet water temperatures and uses SCRs to turn the heating elements on and off at rapid speeds (sometimes 21 times per second), modulating the voltage.Benefits:Energy Efficiency: Saves up to 60% in energy costs compared to traditional water heaters because they only consume power when water is flowing.Unlimited Hot Water: Instant, on-demand heating.No Moving Parts: Increases reliability and reduces maintenance.
