It was the only heater that actually has a mesh frame that kept out the grass from getting stuck on the heating element and burning up.  <\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"temperature-tests\">Temperature Tests<\/h2>\n\n\n\n<p>Besides safety, I wanted to see how well these heaters worked in a tent and which one was most effective.<\/p>\n\n\n\n<p>This turned out to be a bit more tricky than the other tests.  These heaters are radiant or catalytic heaters&#8211;which means they work by emitting directional heat in the form of infrared light (similar to a heat lamp).  <\/p>\n\n\n\n<p>Measuring the temperature of the air does not exactly tell the whole story.  So, take these numbers with a grain of salt.  I think my test method though does compare the heaters <strong>to each other.<\/strong>  So, perhaps the actual temperatures are off, but you can see which heaters heat the best.  <\/p>\n\n\n\n<p>My compromise was that I used two thermometers, one that was 3 ft from the heater where the heat should be, and another thermometer 3 ft away off center from the heater. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"836\" src=\"https:\/\/decideoutside.com\/wp-content\/uploads\/2022\/01\/image-4-1024x836.jpg\" alt=\"\" class=\"wp-image-7552\" srcset=\"https:\/\/decideoutside.com\/wp-content\/uploads\/2022\/01\/image-4-1024x836.jpg 1024w, https:\/\/decideoutside.com\/wp-content\/uploads\/2022\/01\/image-4-940x768.jpg 940w, https:\/\/decideoutside.com\/wp-content\/uploads\/2022\/01\/image-4-768x627.jpg 768w, https:\/\/decideoutside.com\/wp-content\/uploads\/2022\/01\/image-4.jpg 1125w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption>I suspended the thermometer 3ft away directly in front of the center of each heater<\/figcaption><\/figure>\n\n\n\n<p>Next, I did a race&#8211;the first thermometer to go up 5 degrees (from 53F to 58F) won.  The temperature was about the same from 47F to 49F outside the tent.  <\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Heater<\/th><th>Time to Increase By<br>5 Degrees Fahrenheit<br>(Lower is Better)<\/th><th>Temperature After 15 Minutes<br>Starting timer at 53F<br>(Higher Is Better)<\/th><\/tr><\/thead><tbody><tr><td>Martin Radiant \/ Texport<\/td><td>00:08:01<\/td><td>60.4F<\/td><\/tr><tr><td>Martin CH3<\/td><td>00:07:00<\/td><td>61.3F<\/td><\/tr><tr><td>Mr. Heater Little Buddy<\/td><td><strong>00:12:12<\/strong><\/td><td>58.1F<\/td><\/tr><tr><td>Mr. Heater Portable Buddy<\/td><td>00:3:20<\/td><td>65.7F<\/td><\/tr><tr><td>Mr. Heater Golf Cart<\/td><td>00:11:20<\/td><td>58.6F<\/td><\/tr><tr><td>Flame King CHS10<\/td><td><strong>00:02:10<\/strong><\/td><td>68.4F<\/td><\/tr><\/tbody><\/table><figcaption>The Flame King did the best here raising the temperature by 5F in 2 minutes and 10 seconds&#8211;while the Little Buddy took the longest at 12 minutes and 12 seconds.  <\/figcaption><\/figure>\n\n\n\n<p>All in all the Flame King dominated the temperature tests&#8211;rasiging the temperature the most and the fastest.

I admit, these are my weakest tests because I didn&#8217;t start them all off on a new tank of gas&#8211;I was lazy and they all used one tank throughout all the tests.  <\/p>\n\n\n\n<p>However, I think there&#8217;s still some valuable data and you can get a pretty good idea of how long they will last. <strong>All of this is for heaters burning through a single 1lb propane tank<\/strong>.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Heater<\/th><th>Time On High<\/th><th>Time On Low<\/th><\/tr><\/thead><tbody><tr><td>Martin Radiant \/ Texport<\/td><td>04:34:00<\/td><td>00:30:00<\/td><\/tr><tr><td><strong>Martin CH3<\/strong><\/td><td><strong>05:28:00<\/strong><\/td><td><strong>00:36:00<\/strong><\/td><\/tr><tr><td>Mr. Heater Little Buddy<\/td><td>04:54:00<\/td><td>N\/A (No low setting)<\/td><\/tr><tr><td>Mr. Heater Portable Buddy<\/td><td>01:51:00<\/td><td>00:40:00<\/td><\/tr><tr><td>Mr. Heater Golf Cart<\/td><td>05:08:00<\/td><td>N\/A (No Low Setting)<\/td><\/tr><tr><td>Flame King CHS10<\/td><td><strong>01:49:00<\/strong><\/td><td>N\/A (Low Setting Didn&#8217;t Work)<\/td><\/tr><\/tbody><\/table><figcaption>  Flame King burned through the 1lb tank in 1 hour and 49 minutes&#8211;while the Martin CH3 went through 1lb in 5 and a half hours on high plus 36 minutes on low<\/figcaption><\/figure>\n\n\n\n<p>The Martin CH3 advertises that it lasts 7 hours on low and I believe it&#8211;on high it lasted about 5 and a half hours.  <\/p>\n\n\n\n<p>The Portable Buddy was actually much more efficient than the Flame King although it doesn&#8217;t put quite the same amount of heat out&#8211;however, the heat difference vs. the time difference is striking and the Portable Buddy to me did much better as far as efficiency goes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"conclusion\">Conclusion<\/h2>\n\n\n\n<p>In my opinion, the <a href=\"https:\/\/www.amazon.com\/Mr-Heater-F232000-Indoor-Safe-Portable\/dp\/B002G51BZU\">Portable Buddy<\/a> (got mine on Amazon) is the best option and is the only one of these that I decided to keep.  The others are fine pieces of equipment, but I like the flexibility of the Portable Buddy over the Little Buddy.  The Portable Buddy can burn on high and on low and is more stable.  <\/p>\n\n\n\n<p>I talk more about the best three out of this lineup and which ones I would recommend buying in my article, <a href=\"https:\/\/decideoutside.com\/best-tent-heaters\/\" data-type=\"post\" data-id=\"6310\">here<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I spent a ridiculous amount of time testing heaters in a tent.
