Ooops. I just double checked when I got home, and it seems my heater has
not been keeping the temp within 1 degree F like it was in the (Southern California) Autumn.The difference is 2.25 degrees! Our house thermostat was reset at one point, so instead of keeping the ambient temp between 65-74, it is now set to 60-74. Nights have been cold (50's) here as of late, so I do not think that a single 200w Visitherm Stealth can keep up with a 20 degree differential.
This brings up a good point. I read somewhere that a properly sized heater cannot handle much more than a 12 degree difference between the tank's target temp and the ambient room temperature. This seems consistent with my current situation. Therefore, it would be prudent for me to either raise my house thermostat or get a larger (or second) heater. Food for thought on your heater problem.
I have a second Visitherm Stealth that I used to have in the
DT for a while. I think I will be putting it back...
