visitherm heater.

What temp is the water......:)
 
The numbers on the heater are not necessarily the temp, the light comes on when the water temp lowers in relation to the setting on the heater, adjust the heater to regulate the water temp you want and leave it, if you think something is wrong return it.........:)
 
A digital or glass type therms seem to be more accurate than the stick on kind, just FYI.......:)
 
Yeah. I've had stealths that run a couple degrees hotter than the temp dial indicates, but it's constant, so a little bit of tinkering and I've got the temp I want.
