Go gas. The wire run needed and labor to do so will be expensive. Of course, unless, you will do it yourself. Still, your meter will be humming when cranking those things.

Bo brands but the most efficient way is gas fired infrared. But like any infrared there is a clearance issue with combustibles, like 20 feet. But infrared will heat the furniture, floor (slab?) and people without trying to heat the outdoor air. But they need to be vented and installed correctly. An electrical infrared would be my number 2 choice. The internet will find it.
