A wood burning Air Heater or a regular gas burning Air Heater for your home. Wood burning Air Heaters are better for the economy in my opinion, they don't need natural gas. which lets us use that natural gas for other things. When you use a wood burning Air Heater you don't need to worry about a gas bill. Sure you have to go outside and chop wood a lot, but that is also healthier for us to.
A friend of mine lives in a house that uses a wood burning Air Heater and yesterday I got to learn how to chop wood and build a fire to heat the house. I thought it was cool. If I could choose I would use a wood burning Air Heater, I would also try to get a Solar and Wind system to power my home (no electric bill.)
