How to tell when water heater is at max?
When using the electric heating element is there a way to tell when its reached max temp and shuts off? (besides trying to listen) I keep meaning the buy an instant meat thermometer. I suppose i could...
Forum Discussion
There is a very easy And I mean EASY (And safe) way to do it... IN fact a couple of them.. one I have lying in the next room (it is not YET for sale.. that happens much later and not on line)
The two are SURGE GUARD made by Southwire (Formerly TRC)
and the Progressive Industries EMS
We call these Surge Protectors but the top end units are so much more.
1: Like the elcheapo outlet strip "Surge Guards" they supress spikes...
2: They monitor voltage and if it goes too low (or high) they turn you off (See note)
3: they monitor current. (They just report it they don't consider it)
Note: Many are the RVers who plugged into a 30 amp outlet and found it fed with 240 volt instead of 120.. The top end units absolutly protect you if you do this (Lower priced units will not). (Lower priced units also do not monitor current)
So how does this help with the water heater?
With the WH off note the current amps) on a 50 amp note both legs
Now turn on the WH and note the *INCREASE* or agout 12-13 amps (on a 50 amp rig this will be in one leg.
When the increase goes away.. Water heater cut off
