The house is plumbed for natural gas. It runs the hot water heater in the house as well as driving both a gas stove and a gas fire place. I didn't see a line near the pool filtration, though.
I can spend a fair amount of money, but would prefer to go a more cost effective direction. As I said, the house wasn't taken care of properly and so there are quite a few needs elsewhere (i.e., stove, refrigerator, painting, lot of landscaping). Plus, we're looking to enclose a loft area for a movie theater/fifth bedroom, although that could certainly wait.
A pool heater is an absolute necessity and one will be purchased. Would a gas heater be the desired approach? I'm certainly willing to pay a bit more for an energy efficient unit, but I'd like to consider all options. What types are there and what would should I expect to pay for each?
I'll order a test kit in short order.

I'm sure these questions have been gone over before, but I sure appreciate you guys taking the time to walk me through it.
And I'll definitely be spending some time reading other threads and getting "caught up" on the basics and not-so-basics.
