Auto heater cores is something that has been considered..

How many BTUs do you get out of an automotive heater? *SOME heater
cores would be too small, but many are about 100 square inches and 2
1/2 inches thick. The advantage is they are DESIGNED for roughly 3/4"
hose, and the flow rates involved, while radiators are designed for
roughly 2 inch hoses and the much higher flow rates. 2 heater cores
from something like an old impala or Chevy Suburban would likely be
more than adequate.

Trust me, you want a large surface area so you don't restrict the air
flow too much, heater cores are simply too small, unless you used
maybe at least 4 of them
