A professional solution is a trailer-mounted boiler with hoses to
circulate water between the boiler and the hole. One could use a stove,
two pots of water, and a big syringe or pump to draw water from the hole
for reheating. An infrared thermometer would make it easy to monitor
the temperature of the water in the hole.

If you're going to rent equipment, just use a drilling rig.
or a ditch-witch. There's no point in using finesse
when raw power will do.

But still, we're talking three postholes/footings,
not the Comstock.


The boiler trailer shows that the principle works for big excavations.
For postholes I already have a stove, two pots, and a big syringe.
