Does anyone know if gas water heaters have a safety cutout on the gas valve that trips at a certain water temperature?
I know electric ones have trip devices on the thermosat/contactors.
This is why the TPR valves do not see much excitement during their lifespan.
A Watts 210 valve is a gas shut-off that operates if the heater reaches 210 degrees.
Is that what you are referring to?
If you run into a Watt 210, be sure that there is a manually operated pressure release valve somewhere in the hot water line. Check the manufacturer’s website for more information.
Must be automatic, not manually operated.
I don’t see the watts type around here.
I was referring to a possible feature built into the control valve on newer units.
I stand corrected. Here is manufacturer’s spec sheet.
