There would have been a bunch of water discharged... 
I'm not saying impossible or, they wouldn't require that safety function...
But I am saying unlikely.
Take the measurements both temperature and pressure. See what is going on. i would use a lazy hand gauge over a 24 hour period to determine the highest pressure reached.
Post back with your findings... |
Will do.
The more I think about it, the more I believe it's a single bad stat. One heater is dumping HUGE amounts of water into the garage as I mentioned in my first post, while the other is dumping about 10 gallons. It only happens late at night so Im thinking the HVAC system is queuing hot water from the water heaters, the water heaters kick on after the hot water has been sent to the heat coils, the bad stat does not shut off when water temp is reached causing the temp to go up in both heaters thus causing the TP's to react.
I'll post my findings....
