Frugal and Energy Efficient Living

I have a IR remote thermometer that I used to check the tank temp before I fastened the new covers down. Verified the voltage across the heating elements to determine correct operation of the thermostats..

Then measured the faucet water temp with an HVAC thermometer..

When I went to check the amp draw with my clamp on ammeter the 9v battery was dead, I haven't used it in a while. Everything else checked out, the voltage drops seemed consistent so I didn't worry about it. The heater was working fine before the electronic control module died.. We had a thunderstorm the night before, I think it was a voltage spike on the power line that took out the module in the first place..
