Product Description
FS-402 Flow switches used in Tank-less water heater
Tank-less Water Heater heats water instantly to any adjustable temperature (up to a maximum set-point of 120 degrees F). Cold water enters at the bottom and travels through a flow switch which activates the heating unit when the power switch is on. When incoming water exits the flow switch, it comes in contact with stainless steel heating elements which efficiently transfer energy to heat the water.
The flow switches is with compact structure, good quality, made of SUS304 material, with G1/2" mounting threads, the setting rating can be selected from 1.2 LPM to 2.0LPM and used in tank-less water heater.
