Dura Heat EUH4000R Electric Forced Air Heater with Remote Control 12,800 Btu

I bought this heater from Amazon's open-box department because I'm living in my RV in the upper US Midwest this winter before I build my house and wanted a backup to the propane heater system in case I had a problem with it (since I don't know how to work on the propane system nor do I want to go outside and spend hours fixing it when it's below zero) so I wouldn't have to stay in a hotel. I ended up preferring this unit and using it instead of the built-in heater. This heater has worked so good, I think I wasted the money on buying and installing a large-capacity propane tank for the RV, which was way more expensive!Design and build quality:The heater is solidly built and rather heavy. You can't easily knock it over due to the shape and weight, though I don't believe it has a tip-over sensor in either direction. The whole thing is metal. Metal fan, metal housing, very thick conductors (heating elements). Being constructed of metal makes it a bit safer in my opinion as it is harder to catch on fire. The control circuitry, internal wiring, and sensors, are intelligently placed below and separated from the heating elements, which makes them less likely to have a problem due to the heat given off in use. The housing barely gets warm at all when in use, and certainly not enough to burn yourself if you touch it. Airflow is strong enough to feel it from several feet away.Reliability and safety:Running it for hours and hours, literally 24/7 for weeks, the heating elements never got red hot at all, indicating that it is well-designed (oversized heating elements). Other heaters I have had, had coils that would get red hot, which is a safety risk. Cord is of decent quality also, it has not gotten warm either. Minor assembly was required (adding the carry handle, which just required a normal Philips screwdriver).Remote works well and uses 2xAAA batteries. Not the overpriced button cells. The plastic labels covering the buttons on the front of the unit to adjust temperature and power started to crack/peel but didn't affect functionality. Temperature LCD is easy to read but shows intake air temperature rather than room temperature necessarily. So the room overall can be quite a bit warmer than the intake temperature.Noise:It is loud, however. A decibel meter I used a couple feet away read 65dB, so I wear ear protection when I'm close to it, because apparently this is sufficient noise to damage hearing over long periods, which is how I'm using it.Fan and temperature:It has high and low temperature settings, and it switches between the two depending on how far the intake temperature is from the setpoint (this difference is not user-adjustable), but you can also set it to run on either high or low and it will stay on one of them. I would say the user interface is a bit less than intuitive, however it was easy enough to figure out. The fan stays on for several minutes to cool it down after the intake temperature reaches the desired temperature or when it is manually powered off. The fan is single speed with no adjustment, and unless it is doing its cool-down, the heat is always on when the fan is on - you can't use it as a fan only.Only major safety negative I can see is its power cord is a 3-conductor cord, meaning there isn't a separate ground connector. This is considered less safe in the event of a short/fault, and is why old NEMA 10-30 electric dryer plugs are deprecated for household use. Perhaps the housing, being all-metal, is intended to serve as ground, but I didn't see anything in the manual about this.Experience using it:I bought it for my RV, and it works better than the built in propane heater. It keeps the RV much warmer because it doesn't cycle as much (pretty much stays running). My travel trailer is not a four-season model, so it doesn't have the ideal design or insulation for the outside temperatures, which have been as low as -14F (not including windchill). I've been running it 24/7 to heat the RV, a 26' travel trailer, with no functionality or safety issues. I put it the specified distance from anything flammable (including carpet - it's on vinyl flooring) and have it blowing down the hallway from the front to the rear of my travel trailer. I have a small clip on Vornado fan attached to the bedroom door frame to help push the air into the bedroom. I am, however using a standard 1500w heater on medium (750w) to heat the restroom separately with the vent open to release odors and the door closed to the rest of the RV. So it's heating an area about 22'x8'x6.5' quite well. I think it would heat the restroom too if I had the vent closed and door open.About my RV:As for my RV, I haven't modified it at all or added anything to insulate it better than it came from the factory (ie skirting, insulating the single-pane windows with Reflectix or similar), so the heater really is putting out enough heat by itself to make up for the very poor insulation the RV has. Because the RV is not designed for these winters, I haven't tried to use the water system with its exposed tanks and pipes, but I couldn't do that with the propane heater either.With it below zero Fahrenheit outside this morning, this heater is keeping my RV above 75F throughout!A word on connecting it:Please note that you cannot plug it into any outlet in RVs. It takes 240VAC, normal outlets are 120VAC. I have it connected to a heavy duty extension cord with a higher amp rating than the heater requires and an appropriate adapter. (Extension cord usage is not advised by the manual for safety reasons, which is why I oversized the cord). I made sure the connections are out of the snow and used an outdoor-rated cord. It is connected to its own separate circuit. It is not using the RV's wiring at all, it is just placed in there with a cord routed to the power connection outside. A better solution would be to hire an electrician to permanently install a 240VAC outlet for it and the appropriate wiring.I'll update this review if I have any issues with the heater going forward.

This product sucks . I can barely feel the heat coming out even if I’m standing right next to it .Oooooh and last thing it’s not a regular socket for an American house hold . I’m serious this heater is horrible.

You need a 240 plug. Will not plug into a standard outlet. Works awesome to keep my 3 car garage warm.

This is not a furnace blowing flames but it does a good job of pumping out warm air in my garage. Sometimes I will use my kerosene space heather to bring the room to temp fast and then switch to this heater to keep the room warm.The only drawback is the fan noise which can be a bother if your are too close to it or have the radio on while you work. Overall, a good addition my my garage. It is nice to have the option to use this blower to keep me warm while I work on my workbench for short periods of time. As other have mentioned the controls are bit funky but that is no bother for me. The timer function is nice.

I bought this heater in December of last year but wasn’t able to get the 220 volt outlets installed in my garage until this past summer 2024) so it sat in its box waiting until it got cold again and I was finally able to warm up my freezing cold garage/shop, well not so much, first thing is the heaters remote stopped working in a week, I thought the batteries might be dead so I replaced them and still it doesn’t work, but that’s minor In comparison to the heat problem…So I set it up and al that stuff and turned it on and set it to the highest temperature and it comes on, at the time it warmed up to about 50 degrees, but you could only feel the heat if your standing right in front of the thing, and I mean RIGHT in front of it like a foot away, and even then it barely warms your hands..The temperature display doesn’t show a temperature above 25 to 40 degrees and only slightly rises if your standing so close to it that the little bit of heat reflects off your body back into the heater, I bought this because it was 220 volts and I was planning on getting my shop wired for 220 volts, well that didn’t help because this heater is useless at any voltage… I should had bought a kerosene heater or a propane heater… or something even bigger, it’s so cold in my garage and trying to work in that temperature is brutal…

Warms up quickly. I use it in a greenhouse which I use for a workshop. It is not a quiet heater (fan noise), but since if is a place where I sometimes use power tools, the sound of the heater is absorbed in the context. It’s 28 degrees out now and 65 in the shop, so that’ll do!!

Terrible heater it barley puts off any heat I bought it for frozen pipes had better luck with a hair dryer I wouldn’t waste your money

I needed this to keep my garage above freezing when it gets really cold. This did the job. I think some people expect this to put out an enormous amount of heat. If you want more heat you would want a 30amp 240v that can do somewhere around 7,000 watts or even a 50 amp that can do 10,000 watts. I had a 20amp 240v ran for an air compressor that I have so I bought this to be able to plug in there. I knew it would only capable of around 4,000 watts so it was no surprise that this didn't put out heat like the large commercial ones that are at work. The price for this unit was good for what you get. 10/10 would recommend.
