Re: [RE-wrenches] Pt valves as overheat control

[Todd Cory]

Title: Todd Cory

Sure, but the discussion was about preventing hot water storage tanks from exploding. Putting BTUs into a tank, whether that  be from a wood stove loop or 5 kW electric heating element is not the issue. Relying on a P/T valve to regulate overheating is of course not a good idea, but it will prevent the tank from exploding.
