Step 4: Stick This to That

Tent heater:
-drill a hole to mount your dryer duct, RV sewer, or SCAT tube flanges in the two long sidewalls
-you want one hole near the top and one hole near the bottom.
-mount the 12 fan to the hole that will is closest to the mailbox door. 
-test to see if you can open the mailbox door if it was glued to the back panel, if not  mark and cut slots in the back panel with a hack saw or other thin blade to allow it to open fully.
-glue the base of the mailbox to the base panel where you traced it before
-glue the sides and top panel in place as shown. 
(I think you can figure out how to do this without instructions. to be durable I would use marine epoxy and fiberglass tape, but this is also much more expensive) simple 1"x1" strapping glued to all the edges with construction adhesive or gorilla glue would also work but be slightly heavier.
-run a bead of RTV along the top of the mailbox and glue the front panel in place. you want this to be a close tight fit against the top of the mailbox curve so the airflow has to go over the sealed end of the mailbox as that is the warm end. (see second picture)

Thanks so much for this post. Any updates or real-world use?<br><br>I plan to modify this using a small $15 kerosene stove burner (about 8&quot; wide x 8&quot; tall) inside a small stock pot, vented in &amp; out through the window of my camping van. This will eliminate the need &amp; complication of the forced air fan &amp; should be quieter &amp; keep all the radiant heat inside. I'll set it on an insulated &quot;air-bake&quot; cookie sheet and fit the base of the stove into a piece of 2&quot; foam board to keep it secure inside the pot. Might even put a mica window in the side to check the flame while burning. Of course, I'll try to take time to post my results. Thanks again!<br><br>=^)
Bought the parts, and never got around to trying it out. I don't have a need to camp in cold weather the way i would have when I first had the idea.<br>I would love to hear how it works out for you.
<p>interesting concept I do like the idea. I have a couple of duel mantel &quot;Coleman&quot; type lanterns vs the wick type you used. These babies put off tons of light and heat. We even cooked hot dogs over the hot air coming out the top. Granted not fast but it did work. There is also a &quot;tent heater&quot; someone makes.... or did, and right now I can not tell you who it is / was. but in certain places the drive in theaters would rent you one to keep your car warm in the winter months while you watched your movie. They had a large &quot;wick&quot; area of sorts it just glowed with not real open flame. and you def. had to have the window open. But I have one like it as well but your idea of a box to vent the fumes out is brilliant and would make things much safer, Thanks for the idea.</p><p>Hope you recover soon, it is no fun being out of work with and injury.</p><p>Demascus</p>
<p>Conceptual or not, I think this is a brilliant idea and welcome Instructables that are filled with detailed instructions for an idea that should work, even if not tested. I am considering constructing something based on this idea. If I do it, I will definitely post share images and tips. Thank you!</p>
Warning for kerosine lamps in general:<br><br>There are various grades of fuel oil sold as &quot;kerosine&quot;<br><br>Some of these May have flash points as low as 100F. If this is used in a wick type lamp it is likely to result in a runaway condition weth huge flames that can be very unsafe.<br><br>Proper lamp oil has a flash point around 140F, and is what the lamps are meant to burn. <br><br>If the container label leaves any doubt, search online for th MSDS for the product, and that will list the flash point.
<p>In addition to your comment, gumby, I can attest to the poor quality of some of 'made in China' kero lamps. Having two of them explode in normal outdoor use has put me off them forever, now. </p>
<p>I have my Mr. Heater that provides more heat than I could ever need from a propane source and a couple of D-Cell batteries for the internal fan. It has a tip-over and oxygen depletion sensor, so it's not going to cause any problems.</p>
This virtual heater should keep me virtually warm in my virtual world. I could probably use the real lantern and tape measure. Do you have a picture of the finished product?
I came up with this as the answer to a problem I don't have. I camp at campgrounds with 110V, and have a tiny heater that is more than enough. I also don't camp in the winter. <br>Back when i built my tear I was planning on staying in it year round a few nights a week. That has never happened. <br>How to have heat off the grid comes up often on TnTTT, I made this i'ble as a possible answer. <br>I have all the parts sitting in my workshop, but boat building and teardrop modifying has taken up all my free time :( , right now I'm in wood splitting and stacking for the winter mode. I may get to building this and trying it out this winter, but make no promises <br>
Look in the wood stove/fireplace supplies at the local hardware and try to find the fire barrier/fire stop spray in foam. There are several different ratings for this as well as the RTV silicone sealants. If you wet you fingers (spit on them!) you can use them to get a really nice smooth finish on the RTV.
Looks good on LCD. Now go out and build one. If it works I am sure it will be a huge hit. Can't wait to see the prototype.
the outer box wouldn't be that hot, at least I don't think it would be hot enough to melt plastic. <br>I labeled some of the pictures, hope that helps.<br>josh
Some labeling of the parts/sections, flow directions in the diagrams would be nice.<br>Also I wouldn't use the foil faced bubble wrap.<br>(Plastic, melty, burn, poisonous gas, bad, very bad.)<br>Hit up the plumping section of you hardware store for water heater exhaust insulation. It's made to handle the heat and is rather fire proof/resistant. Or even the regular household insulation section, looking specifically for fire rated.
