Thread 2953171

So i've got one of these glorious bad boys right here, i use it in the day in a off grid cabin with a mix of off road diesel and hydraulic fluid i get from loggers for free. The thing is the exhaust wastes half the heat. So i i had an idea:

The exhaust pipe is the same size as the pipe in a old baseboard hot water heater radiator. So why not use one of those radiators as the exhaust pipe? I'd put it vertically in a corner then have it go outside at the top. As long as it was air tight i can't see why it would not work to significantly increase the efficiency.

Note: i NEVER use it at night for safety reasons and because it kills my battery when the sun isn't out.

Good idea

I think some twat on youtube did the same

Just keep it airtight and make sure that there isnt too much resistance

If you could find the link i'd be oh so happy, if it helps motivate you i'm the weirdo who made a random free library and food bank in the middle of nowhere Maine.

>Just keep it airtight and make sure that there isnt too much resistance

It would be mounted vertically in a corner and i'd keep the external metal housing, if i got more than one baseboard radiator i'd use the rest along with my big iron radiator and a little 1920s coal heater to do a water system. The baseboard radiators, they are just a copper pipe with some aluminum fins and a steel housing. I can't see why they wouldn't function as a exhaust pipe since they are thicker and more rust/corrosion resistant than the heat tube for a propane refrigerator and those last forever. Just mount it vertically and you would recapture almost all of the wasted exhaust heat from one of those van heaters.

The odd thing is the van heaters act as air and dust cleaners; the combustion intake sucks in air then expels it outside so it clears out dust and if you throw a kevlar filter bag on the recirculating intake it clears the inside air very quickly. I once had three guys besides myself smoking weed, cigars and chain smoking in a 8x20 foot space as the sun came up through the windows. Sun coming over the ridge, every mote of smoke and dust visible but i realized the solar system was getting blasted with power so i turned it on and within 60 seconds you couldn't see a single particulate.

That Vevor heater cleared the air instantly, we all actually lit up just to see how fast it got rid of the smoke and see it suck it in and expel it.

it probably isnt worth the extra bulk, plus if youre putting oil and stuff in with the diesel itll probably gunk up the radiator quickly

putting a hole in the floor increases road noise, but cutting a hole in the roof seems like a good idea, air tight might not be necessary, hot water heaters use a sharp funnel just before the chimney, i think it regulates pressure.

I got one of these piece of shit chinese diesel furnaces and it leaked exhaust inside my RV, because I had a spare barrel of diesel.
I found the exhaust leak and sealed it with high temp RTV silicone, but I still didn't trust it, so I built a box so I can put the furnace outside the RV, and use a heat exchanger to transfer heat inside the RV, with all the exhaust safely outdoors.
It worked well, but in early on in testing I just completely forgot about the furnace like a retard and left it on without thermostat control and the hoses got too hot and soft and worked themselves loose and spilled coolant inside the RV.
Then a tiler knocked over my barrel of diesel with his truck and the dirt driveway soaked it up.
Overall it was an absolute mess and nightmare, with many mistakes I could have prevented, but didn't.
Thank you for reading my blogpost.

skill issue: the post

OP here, looks like i can just buy 9 foot sections of the exhaust pipe. I can use that and make a water heater while i'm at it.

tastes like diesel and nickel and chromium poisoning, sounds like a good idea!

Why are you drinking water out of a thermal mass? Did your parents install a tap on your radiator when you were a child? I know Brits like tea but that is downright silly, no wonder you all are goofy looking.

>So why not use one of those radiators as the exhaust pipe?

there will be a lot of carbon deposits inside the exhaust/radiator
taking all the energy out of the echaust gasses basically works like a destillery
and the exhaust will catch even more carbon deposits

>but whats bad about it?
1. it will clog the exhaust
2.carbon deposits are flamable

>What I did
I had a straight piece of large oven pipe (6") as the exhaust
And I just pointed a big fan at that pipe, increased the heat output quite a bit

You will badly affect the performance of it by creating an exhaust restriction. Like you can do a little bit of pipe but it starts adding up.
Depends on your space but you can build or really just buy a rather large steel box or cylinder and just route the exhaust into that, exhaust go in and bounces around a bit and exits out of a large 2in opening with very little backpressure added almost none.
Think about it like the finish or russian whole house ovens where the exhaust gets routed into a large chamber behind the oven although not quite similar

The trick is to not do that, and instead get higher distilled version of that fuel called kerosene (k1) and directly burn it inside your dwelling with no exhaust so that 100% of the heat energy is used in heating. It is done this way in Japan. Your house doesn't seal well enough to risk suffocating, natural convection at work. The high grade k1 kerosene does not soot and is very minimal to affecting air quality
