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.
