Thanks guys for all of you help. I'd be very interested in taking a look at some burner designs. I've been looking at a kit on
http://www.ckburners.com to convert a Beckett burner to waste oil. The boiler will also be supplementing domestic heat and hot water. My wife and daughter both can drain a water heater pretty quickly.
I can't imaging finding a dead sheep in the pool. It would definitely be an "off the books" cleanup while my wife wasn't home or she would never get in it again.
I've got a salt system for the pool too and am extremely please with how well it works and how little effort it takes to keep the pool clean. One of the benefits of the generator will be to run the pump at least some to keep the pool clear in the winter without the heater running. I'm in the process of remodeling primarily the yard now and don't have a fence around the pool itself. The first fall we were here I was finishing putting the cover on and one of our dogs decided to walk out on the cover and started to sink. Fortunately, I was able to get him off of the cover, which hasn't been on since, before he sank to the bottom. My wife's young daughter was outside and ran in to tell her mom that Mr. Bob had said a bad word. My mind raced as I tried to remember what I said, which normally would have been noteworthy, but I only called the dog stupid. I'll definitely take a look at a good cover once the fence is up and have also thought about a solar heater to supplement the pool heat.
