Ok, this discussion is way off the original track... BUT
Electric isn't expensive EVERYWHERE. Especially when you use it to operate a Heat Pump.
Wood heat isn't for MOST people as it's very labor intensive and requires time that some people don't have. Or a schedule to accommodate one either.
Then you want to talk about VENTLESS LP heaters....... WHAT A JOKE!!!!! Ever heard of Carbon Monoxide??
You do know CO kills RIGHT??
You do know, you don't use VENTLESS heaters as a primary source of heat, RIGHT?
So to make it plain and simple... you can take those VENTLESS heaters and... well, you get the point.
