RE: [A/S] hot air bubbles

*Jerry, thanks for the reply. Perhaps you have something with the
temperature. The new hot water tank heats the water up a lot more than the
old one. *

I have not been following the thread, and I am sure that you have tried
this, but are you sure that the inlet connections to the heater are air
tight? If there is a slight air leak on the intake the air may be being
introduced with the expansion and contraction of the fluid in the tank. On
what is essentially a vacuum line (when the system is inactive), air can
come into the system without water leaking out.
