Hey Folks,
When I installed SS heat exchangers in wood stoves a while back, I
always made sure to have 2 PT valves in the system for redundancy in
case one stuck or underperformed. Steam explosions are simply no fun.
We'd locate one right on the woodstove outlet and another at the
first bend of that same output. Sometimes there would even be a
third one on the tank as well.

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.

Todd,
I'm afraid that any PT valves that I've ever known have continued
to weep indefinitely after one or two overheat triggers.
I would not recommend relying on them for heat control devices.
