They are tricky in the beginning. You'll have some fits and starts figuring out how to run it correctly. Once you get that figured out the whole system fades into the background. Fill it with wood twice a day and empty the ash pan once a week and forget about it. After tending a woodstove for years the lack of attention you need to pay a boiler is strange at first. I like my Woodgun. I also considered a Tarm. Both would have been a good choice for me. The Woodgun is a little simpler to install as there's no dumpzone required and they seem to be just as happy without storage. Before you buy anything, don't simply believe what you read here. Go look at them. Look at them burning and making heat. Talk face-to-face with the people that are throwing wood into them, not just the people trying to sell you one. I went to the Tarm distributor in New Hampshire and spoke to them. I had lunch with the salesman and walked around their facility. I saw the units together and apart, saw their parts, saw them burning and saw exactly how they worked. I also went to the Woodgun factory and walked the floor, saw them being built and shook hands and talked to the guys building them. I chose the Woodgun because of the simplicity, use of common controls and the availability of replacement parts. I think I made the right choice for me. I could have as easily been saying I went with a Tarm and would have been just as happy. Like a lot of things with good competition, most of the units available these days are pretty darn good. Saying this one or that one is junk is just silly and immature. The truth is any unit with a good name out there will serve you well for years and years. My suggestion is to go out and see them, watch them, and talk to the people using them while you're watching the things work. I have a Woodgun and I live in CT. You're more than welcome to come over and kick tires. Find someone with a Tarm and others that you are interested in and go see them work. Talk to the guys that live with them, not to the guys that are trying to sell them. This is a great forum even with the differences in opinions, and one thing we have is users of all brands that are willing to open up their homes and give you some first-hand experience and advice on they boilers that they are using. Take advantage of that and no matter which boiler you buy, it'll be the right one.
