Since a hot water system is under the same pressure as the cold and provided
that the hot water heater doesn't vent I'l like to know where the dissolved
gases in the hot water go?
tnx

A massive arctic cold wave is heading for the midwest and east. It has
already hit the prairies with record cold and blizzard conditions with
three dead so far. A front of this strength can affect radio reception
so it might be worthwhile to tune through the bands for the next four
days.
Household tip: For some unknown reason, hot water pipes freeze
before cold water pipes.
A trickle of water will prevent pipes from freezing.
Thed Global warming debate will resume in July.

This arctic air has hit the left coast as well.

The deal with the hot water pipe freezing first is due to the lack of
dissolved gasses in the water. That is, the heating process takes the
dissolved gasses out of the water, which in turn makes it easier to
freeze.
