Heater question....
I have a heater that I unplugged for a week or so, It's old and second hand, how can I test it to make sure it's working properly?  I plan on a new one soon but just can't afford now.

Use a spare tank or other container & an accurate thermometer.

Also, make sure there's no condensation inside, that's a pretty good indication that the seal is broken.
