this is cool. I bought an inverter hat is designed to work on three Milwaukee OR DeWalt batteries , made by miller tech. so it allows you to use 120 v things off of your batteries which is nice especially if you are like me and do not have many 12v camping things. when I go camping I take just regular stuff with me that plugs into a wall outlet. of course the amount of juice these batteries hold is not enough to handle really big stuff but I tested it out with my shop vac and it ran it on high for about 20 minutes which is actually pretty impressive considering its a full size shop vac. I wouldn't use it for that of course but for running lights or a fan, charging stuff ect it works pretty well. it was $300 bucks though

I wish l could buy a completed one from you Keagan ❤

As a Milwaukee fan, you caught my eye. As a controls and automation designer, I have a few observations. One is that your heat sink is enclosed, so when the cover is closed, it really is a battery heater. Note that you have wiring resting on the heater. Second, Batteries in Parallel cannot be successfully charged simultaneously, with a single charger. Third, since these are lithium batteries, a fire is a realistic possibility but I see no Individual Isolating Diodes on each battery. Thus, a voltage reduction, in any cell, will result in that fault drawing on the good batteries, potentially at a sufficiently high current, to cause a lithium cell fire, which would turn the entire device into an incendiary problem. It's a valid concept with a marginal circuit design which makes the odds of a fire a non zero number.

Do you know where I can find a battery adapter for rigid?

Hi there, just wondering if it’s possible to get one of the small diesel heaters that would already be assembled? And do you post to Ireland? 🇮🇪

So much wring with this. No fuse protection, no battery protection. This is a cool idea but not nearly good enough to post on youtube in my opinion.

H bro,are you selling it?

Brillant !

What is the point in this? They literally sell all in one units for the same price

Thanks for taking the time for the video. I question the 3d printed fuel pump holder? Isn’t that just a receipt to amplify the already load pump. Mounting it to a hard plastic holder then mounted to the case? Secondly I question having the exhaust and intake so close together, even though different sides of the case. I have found multiple occasions a slight breeze can blow exhaust around the case and drawn into the intake. Thirdly? No muffler? Wow that’s a huge mistake

Since I don't see anyone doing it so I've been passing on the info. I made a true all in one diesel heater using a Ridgid medium size box. Inside I placed the heater, 20ah LFP battery, solar controller, AC to DC charger, cooling fan, light, voltage monitor, USB, 12v socket, charging port, and a 5 liter fuel tank with quick disconnect fuel hose. I just started building another case using the Apache 4800 case. I'm keeping this one simple. I placed the heater with a 50ah LFP battery. I still had room for the controller, 12v socket, and voltage monitor. To keep it clean. I mounted a small external case for the fuel pump and the filter. I just started making extendable legs for the case.

How will you change or replace that inline fuel filter, if it should ever get bunged up?

Buy a tripod!!!

Can someone explain to me how to set up this cord? I love this control panel. I know inside it’s got the 12 volt cord for the thermostat, and alongside the power cord but are these just soldered to the pins?

Just got my parts of the mail from you, do you have any advice on how to make the fuel pump quieter. The 3d printed fuel pump mount being hard plastic really resonates the noise.

Buy a tripod - impossible to watch.

are the 8kw and the 5kw the same size? I am at a mile high and lose efficiency so would like to use a 8kw

Why does the computer fan both wires red and black get soldered to plug number 2?

You have done the best case build i've seen on youtube but used the garbage hose clamps and drilled the bottom of the tank and should have used a stand pipe and gone in from the top,come on man.

Is the computer fan absolutely necessary?

Thanks brotha

Nice works mate! I've built a couple similar power station variations. Something to look out for is the 24v to 12v converter you are using. This has a high guage wire (14 AWG?). So if you have multiple devices plugged in, e.g. a camping fridge and some lights. It will drop below 12v as the wire can't handle the current. This will be more noticeable when you use the long extension cable. if you want a consistent 12v you will need to modify the converter with a lower guage wire. Also, is if you have multiple batteries in parallel. It's best to use some Schottky diode to stop reverse current flowing from one battery to another. If all batteries are fully charged. This step will save your batteries.

Almost like an all in one unit, only more expensive

Is there a reason why people are installing a heater in a plastic box, when you can just buy one that's installed much better for less money that actually looks and works good! Why would you try to suck the warm intake air from inside the box with the lid closed or do you run with it open? Either way, you shouldn't use inside warm air for the burn chamber. Outside air being colder and more dense ignites better, and you really don't want to be using warm air and blowing it outside.

Great job on the 3d parts and a thorough job on the how-to. Just wondering if the 3d parts will work with any other similar 5KW Chinese Diesel heater?

You should really add diodes to the wiring so the batteries aren't back feeding each other. It will function the same, but if one battery loses capacity, the other batteries will be trying to charge into the diminishing one. A diode on each battery would prevent that.

Keegan , I’m very interested in buying these plans . Do you recommend a good power supply ?

Is it possible to lay this set up on its side? Or must it be vertical?

If u dont want leaks from the fuel pipea use proper fuel hose clamps not general hose clamps

Hi keegan, would these work ok when outside exposed to heavy rain?

Are you not concerned about the byproduct from the burnt fuel out through the exhaust ? carbon monoxide poisoning ?

Love the guide! I have a question though. Could I install a 2kw on the 4800 case with the 2kw 3d parts? Would this allow for space to fir the air hose in the case for storage? Thanks!

Love your version of these heater diys! Do you think if I use the 4800 case with the 2kw heatet, cpuld I store the air hose in the case? Or is the space taken up by exhaust and intake? Maybe not worth it? Thanks!

What a great video and it's the one I'm going to follow when I build mine. One question though why put the thermostat in the case? Surely you want that in whatever space you're heating?

Thank you for the brand pipe suggestion! Following a build but I am using a 2kw and ID of the pipe I bought does not work after cutting it unfortunately.

Can you also charge through this?

Hi how are do you have these kits available for the esper 2.2 airtronics heater if you do I will be ordering them tonight

do these heaters run on their side, as in could you lay those boxes flat? obvs fuel tank will need to be upright

Also how do you vent this?

Can these run on used veg ( or other) oil, or mix of diesel/ veg or used motor oil? Thanks

DO NOT!!! use the “dryer” type hose for a regular install, it’s fine for this because it’s so short. On a regular install it’s too flimsy when the heater is running, ask me how I know… Thought it was a good idea for a tight area install and it was until I turned on the heater and the hose got hot… bad idea.

Cleanest build I’ve seen so far!! Thank you for a great write up including the 3D print files and they very cool window mount. I’m going to build my 2KW case using your tips!

Thank you!! anyone else struggling to get the fuel lines onto male ends? The fuel hose diameter I got seems too small even heated - ID 3mm.

Do you still sell the kits??

Do you still sell the kits??

Built this kit utilizing this video as a guide. The instructions were great, precise and easy to follow. I purchased his 3D printed parts and found them to be high quality that have been measured with precision and fit perfectly. You have to appreciate Keegan's attention to detail. You can buy a prebuilt heater for a cheaper price but you don't get the satisfaction that you built it! Thanks for the inspiration and guidance!

Am i missing something? Do you pipe the exhaust out of the building? Not sure whats going on here , like in a hunting cabin.you would have 2 pipe the exhaust out ? Good video thank you

Can we add on solar on this setup
