Without an expansion tank of some sort on your closed system, the pressures are going to be dangerous. You don’t have a relief valve on there to dump the excess pressure, but you should have at least a relief valve and a small airtight expansion tank other than that great job.
The heat to heat the water that goes to the radiator should come from the bottom not from the top. 🤦😄 If you reverse the entries and you will see that it heats much better😉
@@bankdobrychmonet5511 Amazingly few people understand that apparently? Cross flow as you say to have highest efficiency and get the highest temperature of the heated fluid.
@@TimeSurfer206 The water in the water loop rises in this heat exchanger too, enters at the bottom, exits at the top could worke by convection alone like in a water heater. The exhaust is forced, blown by a fan so easily flows downward, it enters at the top where the already heated water, having risen from the bottom, meets the hottest exhaust not having been cooled yet. If it was done as you suggest, the hottest exhaust would meet the coldest water, so on half way, both would be lurk warm, less energy would be transferred. Cross flow ensures there is a temperature difference between the exhaust and the water the entire length of the heat exchanger. A water heater is heat store too, it needs a bubble at the top of hot water, a heat exchanger does not.
MIG on stainless is pretty awful. Use the TIG feature on your welder with Argon shielding gas. Set up a hose to feed Argon inside the tank and pipe work when welding it and it will weld the inside as well as the outside. Tape off openings with masking tape and provide only a small hole for the Argon to flow out. A 1/16" hole will be sufficient. Clean up the welds with a stainless steel wire brush while the welds are still hot.
The lazy ones us us watching this considers just pulling an old central heating water radiator from the trash and route the exhaust through that. Can even accommodate a fair amount of condensation in the bottom before it start coming out of the drain pipe.
Stainless steel work hardens quickly with little effort so when cutting with hole saws cut on slow speed and don’t stop and stainless threads will goral and fuse together so be careful with nuts and bolts
Just buy an all aluminum radiator for a car, no need for building a heat to water exchanger if both units in the same room. Ridiculous use of time and materials.
those exhausts have a condensation drain on the seam ,you may be getting exhaust gasses into the biuilding via that weep hole but its also supposed to be laid with werp hole pointing down to stop crap feeding back into the heater
For free heat, it'd be neat to see something like a wind turbine powering an induction heater that then transfers to a liquid heat storage or transfer medium. But I could only guess the guy in the video doesn't have the space for something like that?
is it just me who notices that there's way too many people who have a negative opinion in the comments on RUclips these days? negativity can strip the motivation from a creative person. as a child I was always told that if you don't have anything nice to say then don't say anything at all and while there are exceptions to the rule I believe it's usually arrogant people who comment negatively on videos and arrogance and ignorance go hand in hand. overall I think it's a good video and awesome concept to use your exhaust to utilize the heat that would otherwise be wasted completely. could it be improved upon definitely but that doesn't mean that everyone should criticize every detail of the build by finding flaws in the design maybe trying to complement the person a little more and build their confidence so they are motivated to keep moving forward with their creativity. nuff said

Welding with MIG on stainless steel? Better with TIG (with argon shielding gas). Try it, it's worth it. The work comes out perfect. However, I congratulate you on the excellent prototype. 👋👋👋👋👋👋👋👋
5:06 the weld is not really penetrating into the base metal DR. You are a crafty person. How much extra heat did you get from the 8KW heater ?? Looks like you got the right idea to save as much as possible fella. v

So after all that its just a diesel heater. You could have just used piping to recirculate the air bk into the system and a simple valve for pressure release. It was more like an abvert for the products used. Pointless
besides the no pop off valve or the exspantion tank put a computer fans on the coils to disapate the heat your setup you could go as big as radiator of a small car then use a heater coil for the exspansion tank and a pop off valve used a high heat water pump to help with movement and go to radiator fuild for better heating but please remeber to put the heater coil on the outside and use nontoxic fuild

Crossflow

you might want to think about that a little longer...
Heat rises, not falls. Look at the internal diagram of the typical electric water heater.

Someone knows how to weld 👍
Nice job!!! I like it. But heat rises, Turn it upside down. Ever better heat.

Anti seize lube on the threads is a must on stainless.
This should be commercially available. Could easily be adapted to many different machines.
its a usual Shell-and-tube heat exchanger

Not bad idea, but that might restrict the exhaust too much, get clogged up.. and it is pretty delicate, so it might start leaking exhaust.

So not free, it's a diesel generator.
But he’s not burning wood. So it’s good for the environment 😂😂😂😂
It's not a diesel generator, it's a burner burning oil to heat a room - get it?

Where do you live on the Sun ? Temperature are gonna drop to 40° C that's bloody hot ! That's 104° F in American .

You should have dump all that wasted heat into a sand battery

You could have probably burned them welds in a little hotter....
Brazing them would have been simple, no need for all the fancy equipment, HVAC technicians braze with silver solder and flow Argon while brazing.

This. Not a. Good vid,, you more or less advertising the machine ,not enough info for the. Heater
You forgot to mention safety gear.
I am wondering if anny condensation in the exhaust exit ?
Nice to show off all your gear shame thest of us only have q hammer and saw?
