1300 gallons?!

Holy cow. That's like, what, an 8 person spa?

IMHO, You'd be better off getting a smaller spa that you can afford to heat.

Still, the trick is getting up to temperature, the easy (easier) part is maintaining that temp.
Where are you located? Is the spa indoors? Enclosed? The trouble with using a house heater is that it would need to be resistant to any of the chemicles you used to sanitize and also, resistant to any sort of bacteria or algae that might form in the tub. since it sounds like you'd be re-circulating the water throught the tank.... I don't think that's a good idea.
