Since all my other equipment is indoors, I'd like to place my heater indoors as well. As you can see, I pre-plumbed tees for installing. I have not purchased one yet, so I don't know if it will even fit. I just hoped to get a professional opinion on the practicality,safety, etc. Does anyone have their heater inside? P.S. Don't knock the plumbing work-the guy that did it was very cheap and not a professional. haha ME!
