It takes 8 btus to raise 1 gallon 1*F
The OP's WH was off, water was secured but system was just left pressurized.
Then he opened a faucet and it spurted.
Trying to make something out of nothing.......
he said ambient temp change of 40 degrees… there are some unknowns here but a closed loop full water piping system that is at 50 PSI can raise the PSI to explosive rates with a few degrees of heat rise…
with no air space to be compressed for the existing water to expand its only option is to increase pressure…
but assuming the system is already pressurized and there is some air space to be compressed by the pressure there is no reason to believe with the mentioned ambient temp change it couldn’t have caused some damage…
from a plumbing repair website without air space…
“Water confined in a storage tank or piping system will, when subjected to a temperature rise of 10 degrees (increasing from 75 to 85 degrees) increases pressure from 50-250psi.”
From what heat source????? It wasn't from the air temp.
Sorry but there just isn't enough btus available and transferable from outside air temps.
