I have basement with over 13,000 square feet w/ 9 feet to upper floor.
When temperature is 0 F outside basement is in low 30's.
Water temperature is in low 40's.
I am wondering if there is enough heat in basement floor & walls to heat 1,000 square feet on upper floor with heat pump.

That is unless the basement is
much larger than the 1000 sq ft. What other choices are there for heat?


OP, you say your upper level is 1,000 sq feet and the basement is 13,000 sq feet?

Is that a typo?

If it really is a 13:1 ratio, it might work.
