"Very unsatisfied"
I would not recommend this Earth Woodsman 400 to anyone. I have owed it for 5 years and every year something goes bad on it. I have done everything you are supposed to do to keep the maintenance up on it and every time I call customer service about the problems they always tell me that the warranty doesn't include whatever is wrong with it. And that's when you finally get them to call you back. So finally after a month they had someone to come look at it and of course they said it wasn't anything they could do because it was my water that had to much calcium in it and was causing the pump to clog up. So if you are looking into buying a unit please don't buy an Earth Woodsman 400.

"Worst stove ever, poor design"
Purchased an outdoor wood furnace to replace a ten year old Northland brand stove. Thought the thicker inside firewall would last longer, which it may, but it's only 3 months into the season and I hate the stove. My Northland stove, when the temperature was 20-30 degrees, had to be filled once every 24 hour job. For the Earth Woodsman, need to fill it every 3-4 hours. And that is if the fire does not go out. I have been burning 3 year old wood and the stove for some reason will not keep any hot coals in it to start the fire. I believe it to be a flawed design with a fan that blows too much air too fast which in return actually blows out the flame. I also believe the chimney where it is located pulls all the heat out when not running, therefore leaving the wood and coal ice cold. Contacted the company, they did not seem to have a reason for it. Since I am stuck with it due to EPA regulations for the new year, I will have to redesign the door and chimney to be similar to my previous furnace. Hopefully it will work better then. I would not recommend this unit for anyone unless you want to live by it to keep the fire going. Thank goodness it has been a mild winter in Wisconsin and I have a backup LP boiler.

"Love my Earth stove"
I have owned my Earth Woodsman 405 now for 2 years. Had an issue from the start with a few components not being installed from the factory but that was resolved quickly. Customer service was great and handled my issue with professional courtesy. I have a 3500 square foot home that is nearly a century old that has no insulation in the walls or floors and very little in the attic and this furnace heats our home great. Not to mention the windows are not up to date either. They do burn a lot of wood , but I was expecting that, anything that holds 2 wheelbarrows full of wood is going to use it. I use it to heat my house and my hot water with a sidearm heat exchanger and 2 heat exchangers in my furnace duct. The heat exchange is about 50 degrees over intake air, which is about 120 degrees Fahrenheit output from my floor registers. It keeps my water heater temperature equal to stove water temperature at 175 degrees Fahrenheit. I also have uninsulated ducts in my house because I haven't had time to wrap them yet. I could save a lot of wood if I had all this done but I don't have time to do all the things I need to. I have to load the stove 2 times a day in the coldest time of winter, once before I go to work and once before I go to bed. I live in the Appalachian mountains region of Virginia. Although not the coldest part of the planet, it can get pretty cold here. I replaced a 130000 BTU diesel furnace with unit and my house has never been warmer. The furnace had a 1.75 GPH burner in it and at 4.00 a gallon, that was very pricey for a winter of heating. For the people who are claiming poor performance and using a lot of wood, I would guess they have an issue with piping underground. I have less than 1 degree loss between my stove and in my basement where the pipes come in. If pipes under ground are not insulated correctly, there can be a tremendous amount of heat loss due to the ground temperature stealing all your heat. And they have to be waterproof or you will have poor performance. I hope this review will be helpful to somebody, because issues like this will affect any brand stove without proper under ground pipe installation. The ground is 55 degrees Fahrenheit and without protecting your water from these elements, your heat will be gone. A 25 dollar laser thermometer from harbour freight would be a real eye opener for some people.

"Amazing Product!!"
My husband and I purchased this boiler a 9 months ago. The initial cost is a little expensive, and the set up can be a pain, but the benefits from this unit is amazing. I believe we got a boiler that is a way to big for our home but we did not want to risk not being able to heat what we needed because our boiler is too small. We also had to travel to purchase our boiler which was not fun. I really wish there were more dealers in our area. Anyway enough of that lets get to the benefits. Since we installed the Woodsman our energy bill dropped from around $350.00 to $450.00 a month to $168.00 for the past 4 months. I could not be more thrilled by that. Any since my husband works on a logging crew we never have to pay for our wood. YAY! Also we have never had a problem with not having hot water or anything such as that since it was installed. You could not ask for a better product. I would recommend this to anyone who wants to cut costs on their energy bill.

"Burns tons of wood"
I have a Woodsman 405 (replacing a smaller Central Boiler CL12?). I have to constantly load this boiler. It has a difficult time getting up to temperature (180 degrees). I load it full before I go to bed, and when I wake up it's empty and the water temperature is around 120. There are not even coals to get the fire going again, so I have to go through restarting the fire from scratch. If I had it to do over again I would go a different route.

"This thing is awesome!"
Just bought this unit this fall and installed it myself to the existing heat duct off my propane furnace! Very good design. I made a few adjustments on the plumbing to fit how I brought in my PEX lines. It is easy to start and operate. Air comes out of the vents just as hot as if the furnace was on. It does use some wood, but that's how they work. The door is huge, and it is easy to load and remove ashes. The digital thermostat is great. This thing hit 180 degrees in less than two hours with cold water and twenty degrees outside. It holds 220 gallons of water so the temperature in the unit is very stable no matter what you're running. If you have problems with an Earth brand furnace, you're doing something wrong. This thing beats any other I've seen!

"Never Buy an Earth"
I have had this unit for 3 years now with no help from the factory or the sales man that told me the stove would heat up to 5000 sq ft but it can't even heat 1500. I had to install a pellet stove to heat my downstairs, then let the stove heat the upstairs. Still will not do it. The factory says I'm not burning dry wood, but all I burn is oak, hickory, and locust that has sat till the bark falls off then its cut split and stacked till burn season starts. If you do get an Earth stove be ready to have a chair out by the door where you can load it all night and day just to keep it at 160 can't even get to the 180 the factory says to run it at

"Woodsman 405"
I bought my stove in 2010. This is the fourth season of heating with it. It is a very simple yet strong design. I have friends with Hardy, Taylor, and free heat machines that are much more expensive. This unit performs just as well as those others which are twice the money. All of them create excessive smoke, so consider that if close to neighbors. The heat is amazing compared to the two heat pumps it replaces (no comparison). I load the stove once a day when mild winter and twice when it's cold, as you know what all day and night. The other brand users do the same. That is a wheel barrow per loading. Also, the whole family can shower while running the dish washer and wash clothes if you want! The more water used the hotter it gets. Everyone is amazed by the size of wood that the stove will accept. I noticed some smoke coming from the siding on the front. When I called Earth the guy said, find the crack if there is one and he would pay for local certified welder without any hassle. That seems fair enough for me. Will let ya know if that's not the case, but I feel like they are good for their word. Four years in, I would buy another Earth furnace.
