  Great video. FYI: they now make microwaves and air conditioners with built in inverters, allowing them to run at low continuous wattage instead of cycling on and off at full power. Breville, Panasonic, and frididaire all have good models.

  What I really want to know is whether stabil storage preserves gas in jerry cans. If the gas evaporates out of the carburetor, I am sure it is only a matter of time before you get to a no-start condition. But I put stabil storage in my jerry cans when I fill them about once a year. I try to avoid leaving gas in the gas tanks of my small engines for a long time. I try to just use them all periodically.

  Thank you for making those calculations. That's disappointing that the specs are so misleading. It seems these diesel heaters aren't even as powerful as two electric space heaters. So if my electricity rate is 12 cents per kWh, how does using diesel to heat compare to resistance heating?

  Nicely done. It's apparent you have some background in getting to a answer that seems to elude most. I purchased 2 of these several years ago after retirement. One for camping, one for a small workshop. My previous life was with the production and maintenance of biogas facilities (municipals) for auxiliary heat/electricity. So I'm well aware of what the CV value of different materials. You explained it well. The producer's of these products should explain it better in their manuals. But then that wouldn't be any FUN.👏👏👍

  I used to heat my workshop with two 2kW electric fan heaters, which were able to heat up the room anytime over 20°C (pretty fast), so the thermostat turned them off. Then, as electricity became expensive I bought a 8kW rated Vevor diesel heater which can't raise the temperature above 14°C, so it is no way 8kW, not even 4. Measured its fuel consumption and figured out it would be still cheaper to heat with electicity. Also in my region (Mid-Europe) the diesel is pretty expensive too.

  My unit uses 79.2cc per pulse; at 5.5 Hz that's 435.6cc per hour. One litre of diesel has 10.35kWh of energy available, so multiply 10.35 by 0.4356 gives 4.508 kWh. Subtract the exhaust heat-loss, I probably get about 3.75kWh of hot air into the room. I run the central heating to keep the house about 16-17deg c, and use the heater at half output to run the living room at 22c

  Great video, thx. Now try running the exhaust gas thru a radiator of some fashion, that would be really fun I would think. The exhaust gets over 400 degrees, if you could capture that in a radiator and then recover that in the living space in the form of radiant heat that would be a fun experiment.

  I used Stabil for a couple years a long time ago in a couple small engines and it worked as far as I can tell. But one engine I didn't use for a couple years would not start and after taking off the carb I found a white powder at the bottom of the fuel bowl. The Stabil had solidified over time so it's not good for long term storage as I can tell. That's when I quit using it and switched to Seafoam and never turned back. Seafoam is far superior in my opinion. It worked for the past 25 years or so. My engines (motorcylces, chainsaw, lawn tractor, push mower and ice auger, etc.) start right up after storage just like they've been running all year. Seafoam is also a good carb cleaner through out the year to keep any engine running smooth. I swear by it.

  That is not an 8KW heater. It's just a 5KW relabeled (yes it's a lie) And most people know it so just buy a 5KW unit and save some money. You will still get about 17000 btu (supposedly) not the 27300 as advertised. Your results sound about right in reality. The truth always prevails.

  Mr. Baker, really enjoyed the time you put into uncovering some of the confusion involving these heater. You touched on some of the heat value lost going out the exhaust of the unit. I was watching a KZread video in which they had set up the exhaust of the heater to pass through an old cast iron radiant heater before venting to the outside. Is there any chance that this would make you curious enough to set up an other Test to determine potential heat gain and potential efficiency gain by routing the exhaust this way. I think of it as a secondary heat exchanger for the chinese heater. Possibly could use 1.5" diameter heavy pipe and fittings to build the secondary heat exchanger and record the heat gain on the secondary heat exchanger and potential gain on efficiency? With this an other issue would have to be addressed is the potential condensate that would develop as the temperature drops in the exhaust gases. At what temperature would the exhaust gases start to condensate? Would it be better to keep the exhaust gases at a higher temperature or to reduce the temperature to lower value to maximize the efficiency gain ? I am thinking along the lines of the newer high efficiency furnaces available now on the market.

  Wonder how many btu is out the tailpipe 🤔 these heaters run extremely clean and can be used in a workshop without exhausting outside (do not do this in a living space/attached garage) they only put out about 30ppm in carbon monoxide, so for a work space it's allowable 😅

  I'm using my diesel heater like that without exhausting to the outside in my garage. In the living spaces so many people use the kerosene heater with wick and the laser models. They don't have any exhaust at all. What is the difference if the diesel heater burns so clean? A diesel heater like the Airrex AH-300i also do not need to exhaust to the outside.

  Great video, clears a lot of myths about these heaters. What you have is probably the Chinese copy of Eberspacher D4. 10300 BTU = 3kW. That's why the original Eberspacher D2 and D4 outputs are rated at 1.8kW and 3kW in High mode. 1.8kW can go up to 2.2kW and 3kW can go up to 4kW in Boost mode. Eberspacher sold these two as 2kW and 4kW.

  An easier test on chinese products is a steam cleaner. They list them as being 2500w on 110-120v. At any voltage in that range they’d constantly pop most breakers. Testing with a Kill-a-watt meter revealed on multiple units sub 1500w power draw. Another unit of a different type was listed as 1700w. That was actually 2000. The takeaway is whatever something is listed at is likely not what it is. Sirry Ameri-cans! Twicks are for chins!

  @YamahaC7SRG7 ай бұрын

  Thanks! Great info!! The 70% efficiency number might be understated because some of the heat is going out the exhaust pipe, which is not shown in this video. As the exhaust moves along the pipe, the pipe will radiate some of the heat back into the room before it exits. If I follow, the final calculation you need is to convert BTU/hr into watts. You can do this by dividing by 3.41. You show 10,348 BTU/hr so, dividing that by 3.41 yields 3034.6 watts. So, this is actually more like a 3kW heater, right?

  What did you do to the metal plate. My is still attached at this point.

• 
  @richardbaker36216 ай бұрын

  I assume you are referring to the metal plate on the bottom of the unit. When I was disassembling the unit I found a ground wire which was pop riveted to the metal plate. I drilled out the pop rivet so I could detach the ground wire. On reassembly I used a small machine bolt to reattach the ground wire before reinstalling the metal plate. Sorry this work was not shown in video. If your unit is plugged only because of lime deposits in ythe boiler, you can clean the boiler without removing the base plate and body of the unit. Review the last few minutes of my video. I made the whole repair process much more difficult than was needed.

For their size and fuel consumption they can certainly put out lots of dry heat

  My question is if the ambient temperature requires wearing a coat and gloves in your garage to keep warm does this heater allow you to remove the coat and gloves? I am trying to decide if buying one of these heaters will put out enough heat such that I can remove my coat and gloves to occupy our two car garage in the winter. There are many videos on U Tube talking about everything except do these heaters provide enough heat to do their job. Thanks for your video. I'm beginning to think that although these heaters are cheap they aren't really practical for heating anything larger than a tent.

  My shop has a floor area of about 900 sq feet and is insulated with 6" batts on the side walls and 4" batts in the ceiling. I have not tired to heat this building with the diesel heater. However, the building is equipped with a 9800 BTUH heat pump which seems to hold the indoor temperature at about 60 degrees when outdoor temperatures are in range of 30 to 40 degrees. The factors that affect heating your garage are going to include how much insulation you have in the walls and ceiling and how tight your overhead doors are to air leakage. The outdoor air temperature is important. These units were probably designed for small spaces such as RV's not heating larger structures.

  Great video! What, may I ask, did you do for a living? I've been using a 8kw Vevor to heat my 12' X 24' shop. This is my third winter using it and I have found it to be most efficient when set to (3). It's air to fuel ratio seems to be optimal at that setting. The heaters internal sensor claims the temperature in the burn chamber is 392 degrees Fahrenheit and turning it up to max will only get you eight more degrees. For my diesel heater the sweet spot is 3. I was thinking about kerosene, which is a little cheaper than off road diesel, until I did the math on the heat output of the two.

  People have made heat exchanger's, out of old vehicle engine EGR coolers, to recover some of the lost heat in the exhaust. The real attraction is cost.......they are cheap, and can be run on gasoline,diesel or black diesel etc. People can even harvest plastic and use pyrolysis to make a crude petroleum liquid ideal for this application. Waste not, want not. The main criticism is that the basic, stock diesel heaters can lack tunability to adjust the parameters to get the best combustion at a given altitude and fuel.
