"Would do it again!"

5.0 rating

We bought our e3000 in 2008. The dealer was wonderful (and still is if we have questions or need something). It has no doubt been the best investment we have made. It keeps our house warmer than the heat pump, heats our water (allows us to turn our water heater way down) and lowers our electric bill during the winter. We love the fact that it does not have grates/an ash catcher. We have found that our stove does not burn wood near as quickly as a stove with grates (several family members/friends have stoves with grates) and allows you to get more out of what you burn. Maintenance is little and is not real hard to do. We make sure to get our water sample in and clean/inspect the fire box thoroughly before lighting off in the fall. The only thing I would change about it is a slightly larger door. Without a doubt, we would purchase another Heatmaster wood stove, and likely will should we ever move from our current residence.

I have owned my 5000e for 4 years now. There's not a day that goes by that I wonder if I should have got something else. This unit is a rather simple design. It is clear that a great deal of its marketability is focused on build quality. While there are options for upgrades like an additional blower discharge unit over the fire base I could not imagine that it would ever be required. I am heating a hydronic floor in the basement in a 4800 square foot Adirondack Style A-frame with a lot of windows. Well I have a hydronic radiator in the plenum of my backup furnace, it is only used if I need a speedy charge of heat after I've been gone 4 longer than a day. I am only using one of the two supplied Outlets from this heat Master unit going into my house. I expect I will use the other for a heating garage when not build comes sometime in the future. I don't expect to need anything more than this unit and quite frankly I'm not sure I want anything else. Easy to clean, easy to maintain, easy to operate. Very Satisfied.

"This heat works for me"

My oil furnace went out during Thanksgiving in 2012. I'd been looking into an outdoor wood system because home heating oil at the time had went to $3.72 a gallon. No sooner than a 500 gal refill my furnace went ca put. Thankfully the house never caught fire from the melted wires. I jumped on the phone and called the nearest outdoor boiler dealer and asked if he could install me a system. We discussed size needs and he recommended a Heatmaster MF-3000e. This being an old 1 1/2 story cold wood framed home. He said if I could get a trench dug from the house to the location I wanted the burner he would be there first thing in the morning. By 7:00 am he was here. It was in the twenties outside and before 11:00 am he had my system installed and the house over 70 degrees inside. This is what I consider my best ever purchase. I have access to plenty of wood and this system works great even with green wood. Now I stay as warm as I want, get exercise gathering wood during the winter and sleep like a baby. The only issue I ever had was when first installed was a sticky air flapper. It seemed after every few hundred openings it would hang open causing it to boil over. No problems as the safety systems worked as it should have. The installer replaced the solenoid and all has performed perfect in the last 5 seasons. Staying as warm as I want, all mess outside and very little caring for ashes and maintenance, I'm very pleased with my system and would recommend this to anyone looking for the same.

We heat 16,400 Sq. Ft. With our stove and I can't say enough good about it. At 30 below, it just idles along and keeps the warehouse, shop and home at 74 degrees and burns little to no wood for being in northern Minnesota. Simple design, easy to maintain and almost fun to burn wood! If, there's is an issue, I guarantee you that the factory people do all they can as fast as they can to help in any way they can. I'm not easily impressed, but making the call to them will be a good thing, and not something you don't want to do. Would I buy another one? YES, IN A HEARTBEAT!!!!!!!!!
