A cool way to make hot water! An immersion heater

[GozonTheGonsarian]

25 bucks? give me 2.

[GozonTheGonsarian]

yah, seems like gas could be a bad idea. what about waste oil?

[tryin2lhard]

Very cool heater, this is pretty much a rocket stove using fluids for your fuel.

Thanks again for sharing man.

[dooley74]

Bad memories of this from K.P. duty in the field, don't do it right and hope you have a long field problem so your eyebrows can grow back

[StatenIslandPrepper]

It always has to be a slow drip,,,but faster than you show on the video,,, ate many c rations heated with this. it should not blossom every time a drop goes down. These things work great!!

Good Luck

[spencnaz]

Start your draft and let it run for about 3 to 4 minutes before dripping fuel in.

[spencnaz]

I run biodiesel in mine to create hot water for my biodiesel reactor. Gasoline can be used but there is a severe danger of back fire during ignition.

[uoit01]

The efficiency of the heater would be greatly increased by piping a air in take from outside so that the heater isn't sucking all the heated air out of the greenhouse. Should be a quick fix and will help keep heat even.

[1anthonybrowning]

That is a wonderful little heater and a great application.

[wyewound]

I remember using one of those in Korea back in 1989. We heated water with Mo-Gas to clean cooking utensis. When lighting the back blast burned my eye lashes off. Luckly my eye brows were covered with a cold weather cap. Fun times. You are using it in a creative way. Great job.

[Urgearhead]

?? would the drum of water hold the temp longer, and maybe be higher if you built a cover for the drum< like a lid on a pot ??

your vid's are great...

[rooftopeagle]

Great video and great idea! If you could get it to the boiling point you could make a lot of safe drinking water!

[SCJMO]

Thanks for sharing, good finds!

[crackonchief]

Hi Engineer775 ..great vids.. how do you think this immersion heater would work with used cooking oil ?

[chance18823]

I love watching your videos, at only 51 years old and finding out a few months ago that I have advanced colon cancer, I refuse to change my lifestyle as a novice prepper. I have shured up my prepping in many areas over the past 2 years. You are a smart man and sometimes I have to watch your videos a dozen times, because I have a family with 2 young boys, my goal, they keep my "prepping legacy" going here even if i'm not around. Thanks again, you have helped me get through some tough nights.

Our prayers are with you!!!

[Horizons84]

What a bargain. Nice find!

[BanditGeorge1]

@engineer as usual , fantastic ideas. Youre gonna need a t shaped pipe on top of that pipe, if it get windy you might also need an inner tire hose( not sure of the name am french) you cut it to approx 30-35 cms then slide it to extremities of the T that should help with wind snow, and youll be surprised, bugs and birds! I mean it!

[ShinySilverForMe]

I answered my own question...search for Immersion Water Heater on ebay

[TheWoodlandMonk]

It would be really cool if you could work that heater into a rocket mass heater system. Also, I would consider insulating all but the south facing windows of that green house to try and minimize heat loss at night (but that would make the cost of the experiment skyrocket)

[OgMandin0]

Nice video! Just so you know, tomatoes will not set buds at temps below 85 degrees F. as memory serves. Tomatoes transpire a huge amount of water and need lots of air circulation in greenhouses to prevent diseases and white flies. Burning hydrocarbons in a greenhouse are not good, either. Releases some bi-product gas which harms the plants.

As well informed as you are I am sure you are way ahead of me on all these fronts and have the solutions in hand. Keep up the good work!

[ShinySilverForMe]

Nice Engineer! where did you get it? I want one!

[BigSlimmyD]

No laughing here, that is cool. My family likes matter sandwiches too.

[MrMajunix]

this is great to see, I would like to know how this works out for you, I have some ideas in mind myself for growing food in the winter, however, I'm in Canada so the winters here are a bit colder. , but I was thinking about having the north side be an earth wall, with 2x4 structure for the roof and angled walls, solar rated 6mil plastic stapled to both sides of the 2x4 to hold heat better, paint the inside black, and run an aquaponics system inside (an above ground pool will hold heat)

[Broylz]

I'd like to see an update ad the tomatoes grow a bit. Would be a very effective way to grow year round. I'm sure the boiler would be easier since you use if for most everything but the immersion heater is a good idea too.

[19hawk11]

Finally a use for my used motor oil I have been saving. I wouldnt mind a $25 green house like that at all. I am probably going to spend more then that on the plastic one I plan on covering my stuff with this winter.

[Bullbunny]

Well I am from the old ARMY ( Pre T-Rats) and we used the immersions heaters they will boil a drum of water in a few minutes, there are alot of different uses for them !!! Good Find, if you know of anymore let me know :) Great Vid

[GaryMule]

Is that like the green house harbor freight sells? Good score!

[EastCoastPrepper]

75 bucks...wow Great deal. Hope they do well. Thanks for sharing...

[HisLass]

We used one of these in a big galvanized animal trough for heating water for bathing. We had a bath tent at first then built a bath house with a deck floor. We would bath Japanese style with a bucket of water dipped from the tub and wash up outside the tub and then soak in the tub of water before the next person. We had no electric or water. So now we have both but we could go back to this if we have to. Never tried charcoal lighter fluid. Our water started at cold well water temp. Nice video.

[coolpat71]

hehe have those in the Cdn forces to heat water for shaving and washing up in the morning. uses gasoline and have seen the smoke stacks launched in the air when lit the wrong way !!

BTW great videos, keep it up. learning lots and im sure other people are as well.

[nate7181]

I have a question, I am not sure how it is working fully, but could you fill the drum with sand instead of water and have the sand as a thermal mass that would hold onto heat longer then the water?

I guess I am not sure if sand or rock would hold onto heat any better than water, really interesting and cool

[hvacbear8]

Gas works quicker and is safe, just be careful. I like those things they work great.

[squidskunk]

far out...

[vention4wh]

LOL! One of those blew up in my face back in my army years.

[steev5x5]

haven't seen one of those in years....looks like it's in great shape too. they work great and don't really "wear out". i would definitely pick one up if i ever saw one.

[khoham]

why dont you make an immersion heater with a used glue gun and immerse it in vegetable oil..

[tsdub]

Sweet heater and setup ...nothing like a good mater samich

[InTheSticks0001]

BTW, white gas works good, burns very clean in a kerosene or oil lamp, but pure vegetable oil does not.

[RCvolunteer1978]

wow i yell when it was 49 *F here in FL this morning MY Father got me a job at an enlisted mess hall to earn enough money for my first car 1974

sometimes they had meals for the troops out by the fly line when they pretent in they war games it was funny as a civitian employee was not allowed to be in some places but Being the son of one of the NCO 's of the base no one saw me doing anything wrong ever

[SultanOfShinola]

Did I miss it? How long did it take to get that drum up to 130 degrees? Very interesting I must say.

[50cmh]

Works like a rocket stove, I've got an idea!!

[scarekrow9]

@50cmh yeah i had one too, trust me's it's been done:(

[BrownDogDuke]

You can't go wrong with only $75 in it. Good luck with the test.

[IronRangeSurvival]

I WANT ONE..=)

[antadefector]

Respects, this is not for laughing. While watching Your video, something came up my mind... With this kind of tubing trough water (or air), or something like intercooler radiator, You could recuperate heat made by wood gasifier, to cool the gas. Same on motor outlet... Your idea to use a heat reservoar in this way is great!!! Thanks for sharing!

[TheHomeDefender]

Very nice setup.  Thanks for sharing.

[bear83706]

Awesome! thanks for the info you put out. I am now a subscriber.

[carr869]

Those things are cool. They work great and will burn just about anything that wont clog em up. Aint seen one of those things since I was with the 82 nd back in 1971. Damn I'm old.

[TheMimeChef]

Love it !

[cpranga9488]

Would it be possible to use old cooking oil in this? Or maybe even old motor oil?

[carmas54]

very cool... you can't go to the supermarket for less these days

[timbeverly192617]

Another great use and Idea........ . . . .

[FrontCortex]

I always read all the comments on great videos like this. Frgtmygld posted that he got one of these GI Immersion Heaters at Old Grouch Military Surplus. They do have them listed for $63 right now, with an apology for having to raise the price a bit.

Thanks for another great video.

[freedomsailer]

Very Kewl, i think you'll have em fresh home grown mater sammiches all winter long

[noshoes]

$50 wow!

[mdr8088]

Be carefull with that heater, back in my reserve days, I seen one of them catch on fire. That was with gas, but I've never trusted them since. Cool green house!

[dfgiuy22]

@mdr8088 How? Some people shouldn't play with fire...

[mdr8088]

@dfgiuy22 I'm not sure how they did it, you have to watch how much fuel is dripping in. It might have been a fuel leak in the tank too. I never actually seen the fire, but I'm told it was pretty impressive. Not trying to be a xxxx, just trying to throw a word of caution...

[mmlrc6atgmailcom]

That is a great building , your tomatoes need blooms by now and green tomatoes by nov to have ripe ones by christmas day  , great job ...mountainman

[mrseansbushcraft]

Dude, Your the man. Great videos and very informative. Love it.

Sean

[Apaulshi]

Still rejoicing, not yet jealous, I hope :-) Seriously, this is cool. I want you to do some aquaponics and Black Soldier Fly experiments!

[modernblacksmith]

sweet! giving me some ideas...

[scarekrow9]

how did you get 3400 bottles of charcoal lighter fluid?

[ThePatriotsChoice]

@scarekrow9 He already explained in the last video. He got them for free from a friend/contact that had to remove them from a big box store because they did not sell. If you have a product that does not sell, what do you do with it?

[Jaygoodpatriot]

Never knew that even existed. Thanks for posting that is a great start to another new idea. Did you check out Eastcoastpreppers latest video about a guy running his world off Hydrogen? If not, check it out. Seems like your cup of Tea. Take care.

[jplerwill]

On my last propertty we were experimenting with a rocket mass heater to heat water, then adding a thermal gravity loop to the system to draw the water without a pump up into a tank, and then to an outdooor shower. It didnt circulate on its own as much as I liked, so i did eventually install a bypass and a hand crank pump to recirculate the water from the lower heating tank up to the larger storage one.

[MrOurcanada]

well 75$ good deal lets us know how it all works out

[1LRLRG]

to buckstarchaser, this type of heater was normally in HQ area where the chow tents were and was primarily for cleaning and such. Using gas they were prone to blowing up as some people tried to fill while running and sometimes the water had a gasey taint to it. Nice video and definetly a steal at $50.

[darbycrash55]

I wonder if you could use other sources of fuel oil such as bio diesel or Vegi oil.

[halfhawk2012]

ummm how did u get that many

[1111Davo1]

I wonder how efficient it actually is. In comparison you already have that wood fired generator you could probably feed copper piping through pretty easily.

[buckstarchaser]

That's really nifty! That warm water should hold good heat after the fuel's gone and store the daytime heat from the sun too... The extra humidity may also be good or maybe bad. I was trying to think of why the military would have this kind of heater since it would likely make a tent soggy from the water... Hot showers and dishwater is probably the answer.

Will this suck in a lot of cold air from outside for the fire? Would it be hard to make an air pipe that feeds it from outside?

[ThirtyAcrePrep]

@buckstarchaser Those heaters were used in the field messhalls to heat water to boiling to sterilize messkits, heat canned C rations, heat water for dishwashing ect. They were not used or meant for tent heaters.

They will get water to a violent rolling boil in a short period of time. We used them in the army and I've wanted one for years. I just ordered mine from a surplus store. :^)

[MyDaddysgirl44]

Just wondering if your wife... would rent you out...LOL Great video!! The wheels in your mind are always turning.....TJ

[ds10363]

You should teach a college course on this kind of stuff man. This is real world practical knowledge. So glad to know you on here. You are a true asset to the prepping community brother. No joke. Thanks so much for sharing everything you do on here.

[scodurh]

I cant find one of those for less than 150 :(

[FrontCortex]

@scodurh Old Grouch Military Surplus has them listed for $63.

[badatcards]

My friend has a Lister Diesel Engine he uses to run a back up generator and in the tank for the engine antifreeze he put a copper coil so he can run clean water through it for doing laundry or whatever. and it also take away a lot of heat from the engine. He asked me to put up a few video's of it on my You tube ch so he could show some people. The neat thing about it is it can run on almost any oil, You just have to clean it every 500 hours if it's dirty. here is 1 of them /watch?v=77wiB_lKtog

[america2revolt]

Good way to keep the right amount of humidity in your green house through the winter too..

[AppalachianFreedom]

Very nice!

[frgtmygld]

I just picked one of those up from Old Grouch Surplus after hearing about them on Thesurvivalpodcast. I didn't know they were still available.

After a lot of camping I've found that a wife can actually be happy for extended periods of time if you pour her coffee while she sits in a hot tub enjoying the view.

I guess you could call this heater a marital aid of sorts.

[vcqcfoda2]

this thing looks kinda dangerous.. but is AWESOME!!

[Mrcaffinebean]

Reminds me of the principle of a pulse jet. Kinda had the same sound too.

[sonnysand]

Very cool, didn't know that was even made

[lpdavisakgto]

Been working on a solar hot water batch heater got the water up to 178 so far works well programming plc for emergency dump for temp and power loss but no power is needed works of gravity and hols 38 gallon s

[pfcwar5150]

interesting,never seen anything like that.

[360steven]

good video engineer keep up the good work also have you ever thought about geting an electric golf kart there really alot of fun and im sure you can think of something cool to do with them anyway great video keep up the good work

[standingbear39]

Very cool and at a great price, I love the stuff you come up with.

[InTheSticks0001]

It might do well in kerosene lamps as it is or mixed with kerosene.

[InTheSticks0001]

@InTheSticks0001 BTW, SolarEnergyKit have the lowest prices on Solar panel charge controllers. For example they offer the Outback Flex 80 for only $400, between 2 and $400 less than anybody else. Morningstar TSMPPT60 = $300. Killer prices.

[Iam1uglyguy]

Very cool!!

[pr4runner]

Never seen one of those before. Do you have a NSN # for the heater? 

[tysy73]

Very neat. How long does it take to heat that drum of water?

[Myrmidon26]

wow, that's pretty awesome. Where did you find a greenhouse for $25?
