Thanks for the reply. Sounds right on. I was just playing with the
Tstat. There is an adjustable arm behind the main control (this is the
round heat only style stat). After a few adjustments I think it will do
the trick. My father has a habit of playing with things like that, not
really knowing what he has done. I do plan to replace the unit with an
oil burning unit for both heat and hot water, using WVO or biodiesel
for fuel. Again, thanks for the reply.
