WE DON'T NEED NO STINKIN' THERMOSTAT..
OOPS sorry for yelling...
i just meant to say that i have wood heat.
since my stove also heats water, sometimes
i have a fire and have doors and windows
open for fresh air.
the water is heated in a loop of pipe that
goes thru the fire box and into a water heater
(formerly an electric one) which thermosiphons
thru the hot water tank via two pipes, cold out
of the lower part and hot into the upper part.
(as long as (bottom of) the tank is above the
(top of the )stove (the electric tank is more
insulated because the propane one has a flue
up the middle which allows heat to escape if
not burning gas. IMPORTANT: don't forget the
pressure relief valve! sometimes i have to
run a sink or tub full of H2OT to draw off heat.
