i heat my 20x100 greenhouse with propane currently. it is darn expensive but dependable and consistent.

i aspire to do geothermal supplemented with propane for my next one which will be cheap after the initial outlay and should also be dependable and consistent.

wood is my cheapest option but is a fairly constant chore.

for something the size you are talking about i would think propane or electric would be your best options, neither one of which is going to be particularly cheap. a wood stove would likely be overkill for that size space.

much also depends on how warm you aspire to keep it... are you overwintering fairly hardy plants (40 degrees) or growing tropicals (seventy degrees)?
