Mr. Heater MH70KTFR 70,000 BTU Portable Kerosene Radiant Heater with Quiet Burner Technology for Jobsites, Workshops, Or Large Outdoor Areas

I got this heater for my shop and I can say it does a great job of warming things up, even to the point where I actually have to turn it off because it gets so warm inside. I don't recommend using it in an enclosed area but my shop is large, almost 2000 square feet and it's not that well insulated.The heater is pretty easy to assemble, the instructions are simple and well-written, it took me about 15 minutes total and I wasn't in a hurry at all. The heater uses a fuel filter which is on the outside of the unit so it's easy to replace and they also include a spare fuel filter as well.I use #2 diesel in my heater because it's just easier for me and the heater doesn't put out much in the way of fumes or smell. But, you do get some initial fumes and smell when the heater first starts up, afterwards, it's not bad but again, be VERY cautious if you're using this indoors.The fuel tank is located on the bottom of the unit and can be a bit tricky to pour fuel into it, especially if you're using a five-gallon fuel can. I have use a battery powered fuel transfer pump I got off of Amazon and it works great! Here's a link to that product: https://www.amazon.com/dp/B0DJN32859To operate the heater, you plug it into power, you'll need an extension cord because the cord from it is very short, turn the switch located on the back to on, then adjust the thermostat to a temp higher than the surrounding temp. The heater will come on but the burner takes a few seconds before it lights. Once it comes on, the grid in front gets hot fairly quickly and glows red. I tested how close you could get to the front where the heat comes from to see if it would ignite some paper - within two feet, the paper started to turn brown and within 18 inches, the paper caught fire. Make sure to not have anything, especially flammables, anywhere close to the front of the heater.Overall, I'm well pleased with this heater. It seems well-built and definitely puts out quite a bit of heat. It would be great for outdoors, while camping, tailgating or in any situation where auxiliary heat is needed. I highly recommend this one!

Review after one year of use:This kerosene heater is designed and adjusted for kerosene use. Let me explain adjusted ; When tested for performance they use white or clear kerosene. Yes it will run on diesel, heating oil #1 heating oil #2 and or jet fuel. White or clear kerosene has a thinner viscosity than diesel, healing oil#1,2 The viscosity is a little thicker not by much but a little. There is a little bit of difference between pump kerosene and kerosene that you get off of the shelf in a 2 1/2 gallon container. The kerosene that you get off the shelf in a 2 1/2 gallon container is a little bit more refined than the pump kerosene from a gas station. Running this unit on white or clear kerosene starts and runs perfectly. If you want to run diesel and or heating oil #1,2 You will have to do the following for this unit to start properly at colder temperatures with out an E1 code. This is through trial and error on my part. BeFor I get into that this is what I did before I came up with this conclusion.Yes unit is sluggish to start on diesel & heating oil, In colder temperatures of below 40°.1, Replaced fuel filter twice2 Replaced injector nozzle onceWith no change in start up performanceAfter some research I found that there is an adjustment on the pressure regulator pump which needs to be adjusted to start and run better on diesel, and heating oil without the E1 code.I have read all of the reviews on this unit, some have complained about a faulty thermostat which has nothing to do with the start up and running of this unit. Most have complained about the E1 code which is because the fuel that was put into the unit was not the fuel as tested(White or clear kerosene) however yes the unit will run on diesel and or heating oil , it will have starting issues at colder temperatures. But of course that defeats the purpose of having a heater you want a heater to start and run at colder temperatures so you can be comfortable.Disclaimer: this is my own observation And test results, your results may vary. Proceed with caution!On the back of the unit you have the digital display the temperature knob and the on off switchThere are four screws that hold the back portion of the heater which contain the LED display, temperature thermostat and on off switch. Remove four screws which part indented. Carefully pull the covering away there are wires in the back that you need to be careful about. Looking at the unit from back to front on the right hand side there is a pressure regulator, The pressure regulator has a thumb screw this is a lead and a test port . Next to the bleed screw there is another screw that is flush with the pump/regulator with a black Marker line drawn through the screw, that is The factory setting. If you were going to run diesel or heating oil in the unit. Put the appropriate amount of fuel into the unit. A minimum of 2 gallons. Plug-in unit with backing cover removed. Turn pressure regulator screw clockwise 1/4 turn (in) , turn unit on. Wait for unit to start , If the unit does not start right away turn screw in clockwise another 1/4 turn. This should be sufficient for the unit to start properly on diesel, and or heating oil.This is my own observation. Your results may vary.So far as of today (Nov 13 2019) his unit has started perfectly on 100% heating oil. In the past it was extremely sluggish or did not start at all on diesel oil or eating oil, it would only start on clear/white kerosene or pump kerosene.Make this adjustment at your own risk.I will give an update as the temperature gets colder. With a picture of the pump/pressure regulator adjustment screw.

Checked unit right out of box, back cover no cracks, went over all nuts and bolts for tightness (only one needed tightening). Filled tank half full of kerosene just in case of any leaks, no leaks. Using product called Klean-Heat for fuel. Plugged unit in, switched on, set dial and it fired right up, not even any pump prime noise or smoke. Going to run a couple of tanks of the Klean-Heat to make sure all is okay then maybe switch to another type of fuel. Gave 4 stars for slight kerosene smell even with proper ventilation.The thermostat is off compared to one that is mounted chest level in my garage, the sensor is on the bottom in back where the cold air drawn in. I think raising the unit will change the temp to more of actual room temp, not a deal breaker. If smell clears up as other videos say happens after a few uses then it's an easy 5 stars. Assembly couldn't be any easier.My garage is 20x20 and this thing went from 42deg to 60deg in 18mins!Would recommend...Stay Warm!
