Last year I was considering the same thing. I thought wood was a great alternative considering the price of gas or electricity. I found the same wood fired heater that you linked to in the above post but I was unable to find any reviews. My wife thought I was crazy but I ordered it anyway.

All things considered I am glad I have it. The heater is build very well and does as advertised. My water temp has a nice steady rise with a HOT fire. For best results I need to add wood every 2 hours. So you might think that is a draw back. It is not something that you can fire up and forget about.

One of my biggest concerns was that I smelling smoke all day. That proved to not be the case. Once the fire is hot, there is no smoke or smell.

I also found a few different websites with the same heater. The prices varied and so did the shipping. I think it would be against forum rules to post which site was cheapest and I dont want to endorse anyone. I am just suggesting that you shop around and you might save a few bucks.
