if anyone wants a cheap super simple way to extract heat from the exhaust, just buy a pack of scotch bright stainless steel scrubbers. You can expand them from the middle and slip them onto the exhaust pipe. They have a ton of surface area and conduct heat from the pipe really well. they work pretty well already by passive heating, but you can add a fan to help a little. You can buy a 16 pack for $10. Thats all you need.

Ive been doing this for 3 years with an old steam radiator, have many videos about it here on YT. It works fantastic, no condensation problems as the armchair quarterbacks and internet experts always bring up. I have over 1000 hours of use with no issues, you want the exhaust from the heater to go in on the bottom of the radiator, exhaust out the top port which allows convection and hot air rising to remove condensation. The large internal volume of the steam radiator prevents backpressure so the combustion fan doesnt work too hard like it would with a long exhaust run, the hot air convection from the heater exhaust coming in from the bottom and exiting out the top (in my system) propels the exhaust out without putting undue work on the heaters fan, it also allows the stored heat in the thermal mass to continue to remove moisture even when the heater is off.

How does condensation not end up sitting in bottom of radiator? Or are you saying the heat vaporizes it and pushes it out with the exhaust? Seems like the down draft shown here would simply allow the moisture that's created to flow out with the exhaust at the bottom. Or are you saying the condensation that is created simply does not create any problems?
@daveunderwood6498 2 ай бұрын
I have to say that this is one of the best ideas I have seen on KZfaq. Of course condensation will form in the rad, but being cast iron and the exhaust low, it will drip out the bottom. Those heaters burn so efficiently that you won't have to worry about soot collecting in the rad. To test for this possibility, when it's new, record the temperature drop from top of rad to the bottom. After running it for months, or years, keep testing the temperature difference. If soot is forming on the inside of the rad, the temperature difference will become less. The exhaust temperature, at the floor will increase. The soot will act as an insulation. I can't see that happening though because of the burn efficiency. I only thing I would do differently is a more positive, sealed connection between the iron pipe and the heaters' flex line. Easy fix. As for the haters in the comment section, these people are shocking ignorant to basic science. You can tell they have done nothing in life. Nice job. It has given me some ideas.👍

Many people who watch this video are of the opinion in their comments that heat rises upwards, which is physically correct, but cold falls downwards, which also creates a downward suction in the radiator. That's why the entrance is always at the top and the cold that occurs when it cools down doesn't have to fight against the rising heat. On a car radiator the hot water inlet is at the top and on a household radiator the inlet is always at the top to achieve optimal heat exchange. It is also correct that you should not make the exhaust pipe too long, otherwise the resulting flow resistance will be too high, but given the flow cross section and the length of the components installed here, this shouldn't really have an impact. Since the difference in height between the exhaust gas outlet and the radiator inlet is approximately 45 cm or 18", there is virtually no back pressure. An exhaust silencer would generate more back pressure. And with an exhaust gas temperature of over 150 degrees Celsius, there is guaranteed to be no condensation in the pipe On the contrary, it will evaporate and condense again in the radiator where this condensate can then drain downwards. It is absolutely likely that deposits will accumulate somewhere in the system, but the solution to this is regular maintenance and cleaning. Every boiler, fireplace and chimney must be cleaned regularly, even Chinese diesel heaters are not maintenance-free forever.

I like your design and am planning something similar...after seeing a bunch of Tubbers designs I think an oil or car radiator would be most efficient but I worry about corrosion. My idea is to run the exhaust thru a honda or toyota radiator and have the fan cycled with a fan relay in the heater, but i wonder how long it will last w/o antifreeze. That one your using is designed to run water through isn't it? an oil radiator might not last with water going through it either.

On a Russian site a man did this and did a lot of calculations based on the actual heat values - he concluded the heater itself produced just over 4kw on high and his radiator added a further 1.5 kw making a total of a little over 5.5kw - in another of his posts, he concluded that the 5 and 8kw heaters were in most cases the same!

Make sure you can drain the radiator because the exhaust is humid and going through the rad it will condensate the water in it, unless the output is right at the bottom. . Place a few computer fans blowing against the rad to dissipate some of that heat into the room. Also you should be getting fresh air from outside because you are using the air in the shop and exhaust is pushing that air out so to compensate for the air going out, it will draft into the shed from all the cracks
@robertscholz4486 4 ай бұрын
Nice idea to recoup the heat lost by the exhaust, but I would have turned the unit around to have the heat vent also blowing through the radiator. This would have a two fold benefit: 1. it would help to heat up the thermal mass of the cast iron radiator quicker, and 2. Once up to operating temperature the hot air passing through the fins of the now heated radiator would distribute the heat from the radiator better. On a side note, I would definitely add a 90° elbow to that exhaust under the shop and run it out from the perimeter of the shop (the rockwool may help where you drilled the hole, but there may be a couple seams on the underside to let fumes back up into the shop).
@daleb5967 4 ай бұрын
Not really. Heat inside is what matters. If you transfer heat to other objects changes nothing .....unless it increase heat radiated to the outside, which it might. Capturing exhaust heat helps but dumping heat into a cast iron heat exchanger instead of aluminum is less efficient but better than just dumping it.

Great idea! Since the unit and the exhaust path is inside, please make sure to have a small space carbon monoxide detector (they are made for inside of small spaces like airplanes and semi trucks and are more sensitive) inside the shop/shed. I agree with the comment that the outside exhaust outlet should be extended past the building side (instead of just down under the shed floor - ideally up past the roof peak). Also, keep an eye on the temp of the pipe going through the floor to ensure the mineral wool is taking any residual heat before it reaches the flooring wood (thinking of a chimney wall/ceiling collar and how it separates the combustible surfaces from the heat of the exhaust pipe). Nicely done!

better go for a stainless steel pipe with slightly larger inner diameter as your exhaust hose and root the exhaust gas through that. I use a 2.6m long pipe that simply goes through the room and then exits with a slight downward slope. The pipe then just goes through the wall. The end of the pipe is at around 30°C so i get the same efficiency with much less effort and dont even have corrosion problems. I put a small bucked that collects the condensate under the exit of the pipe outside of the building so the sulfur does not go into the environment. The whole thing cost me around 30 bucks.

Good to see someone else in NS doing stuff like this besides me. LOL Been using these CDH for a while. You will have issues with carbon build up eventually and condensation building up with the exhaust angled upward like that. Everything on the exhaust should be on a downward slope to prevent condensation build up and giving it a path to drain. Also move the combustion air intake outside of the space, when it does foul up it and it will at some point it will dump all the exhaust gases back through the intake manifold into your room because the intake and exhaust share the same combustion space. CO monitors are a must. Stay safe and good luck.

Problem you are going to have with this setup is condensation in the radiator. The condensate is very acidic so it will rust that radiator though in no time. You can get round that however by using a stainless steel radiator. Also you need to have the exhaust coming out of the heater going down into the radiator so there is no chance of condensate collecting in the tube. I have a similar setup myself except I packed the exhaust radiator in sand as thermal storage so I can turn off the heater and get several hours of residual heat.

Nice idea - I may give that a shot. I think you definitely need some kind of drain for condensation, though. You are dropping the air temp down to well below condensation temp by the time it exits the radiator, so I am betting you will soon have the bottom of the radiator full of fairly acidic condensate, which will likely do some significant damage to the internals of the radiator in the short term if you don't have a way to drain it. The cast iron would last a century if you ran clean water through it, but letting acidic water sit in the bottom will do significant harm to it. Even if the radiator cast iron holds out, you will eventually be dumping that acidic water out onto your cement slab. If you don't want to put in a drain, I would think about pouring in some thin epoxy like the stuff mean to repair pinholes in gas tanks, and flipping the radiator around until it is coated inside evenly. The epoxy may give you some extra time before the radiator bottom perforates. Thanks for the great idea!
@Redbeardsgarage967 4 ай бұрын
If your exhaust temp is lower than 140° it will condensate which is acidic which WILL rust that radiator out faster than you think. If the rad was stainless you wouldn’t have that problem. This is exactly the reason high efficient furnaces / boilers/ hot water heaters cannot use regular tin exhaust vents, they have to be able to resist the acid which is present in consensate.

I think you'd be able to increase the efficiency by using outside air for the combustion air intake instead of indoor air. You're creating a negative pressure space, drawing cold in inside the building. Outside air will combust the fuel just as well and wont create a negative pressure. In the end you'll use much less fuel to heat the indoor air.

That's a brilliant idea, but a few suggestions: Have the exhaust enter from the bottom of the radiator and exit from the top. Also the exhaust should enter on one side and exit from the other. If the exhaust gets too restricted incomplete combustion will occur.
@ColCurtis 3 ай бұрын
No. If the exhaust enters from the bottom, there is no way to get rid of condensation. Condensation occurs when the exhaust drops below 100C. There is a reason the exhaust temp from the heater is above waters boiling point. Why enter one side and exit the other? He already showed that he is extracting all the heat from the exhaust, so much that his exhaust Temps are below zero, causing the condensation to freeze in the radiator.

@@ColCurtis Physics Still a closed system. If what you stated was true, eventually the exhaust would become blocked from the freezing condensate, filling the room with exhaust gases and killing everyone inside. Ever see an air compressor tank condensate valve? That is the ONLY proper way to drain the system. Every other way relies on pressure. The freezing readings were from the outside of the pipe, where the outside air was flowing into the area and over the outside surface of the pipe not from the exhaust gas exiting the pipe.

@@stans5270 if he keeps the bottom exhaust pipe temp above freezing the condensation will run out the bottom exhaust pipe. It is not a closed system if the bottom pipe is open. I would Insulate the bottom pipe to keep it room temp.

Nice and effective idea. But do not let you fool with IR measurements. Shiny metals refelct either the room temperature or your own body temperature. If you want to measure correctly you need to paint the shiny metal in black or stick black electrical tape to the measurement location. I proved this fact with my IR Camera. If you put a shiny aluminium sheet on the pavement at a sunny summer day, it will get very hot. Nevertheless it will refelct the very cool sky temperature only. And exactly that you will measure. If you approach your face above the sheet you will measure partly your skin temperature. In the camera you will see the outline of your head.

I had thoughts of trying to capture the heat from the exhaust but everything I thought I was way more complicated than this. My only thought is that I would use a high temperature silicone hose to connect the radiator instead of metal tape. But excellent job I think I'm going to do this instead.

You need to drill and tap a small 1/4" fitting into the lowest point of the radiator to drain the acidic condensate out otherwise it'll sit in there and eat away at the steel and eventually leak out through the rust holes it'll make. The 1/4" brass fitting can have a drain line that can be run outside so that condensate build up will drain on it's own.

Great idea!! I can suggest you to improve the insulation of the exaust gas outlet or reduce the number of radiator elements to improve the heater draft. Gases must be prevented from condensing inside the elements

the 1st thing I did when I got my diesel-heater was to install an old radiator along with it. The exshausts gets hotter than the wearm air coming out and we do really need to take care of that. The radiator got so hot the paint on it burnt. I sandblasted it and its been running perfect since. Exhausts are cold even after 2 hours running. After about a minute u cant touch the radiator near the inlet. Im aslo running my own diesel fuel cutting down costs even more.

I like the idea that you tried out and many people have good suggestions to help improve the design. I think I myself would have gone in a different direction using the same principle that you have used. What I want to test out is more costly but I really want to try and see the outcome. I'm interested in trying out the radiator but I think I will try using a heat exchanger in order to heat up a super insulated tank of glycol mixture that will itself circulate through a cast iron radiator with a circulating pump. This way you keep the exhaust in its own little world where it can condensate, drip where it needs to and the heating part free of the corrosive elements. I might be wrong but I think the glycol mixture might have a better contact throughout the radiator and possibly make it dissipate heat more evenly. Anyways it's an idea I want to try and see how good that version might work.

That was cool! Could you have hooked the exhaust to the bottom of the radiator first and then run a longer pipe from the top of the radiator down and to the outside? The idea being to keep the exhaust moving in a downward direction, as others have discussed at length.
@greenhometony 4 ай бұрын
Yep
@matzstrom3223 4 ай бұрын
The idea to have the exhaust moving in a downward direction is also safety reason, if the chamber get flooded with fuel it should drain out by it self. And if the exhaust pipe inside and the gases stays well above 60 C it will dry out the pipe but maybe not the radiator, even if outgoing gases from that stays well above 60 C.

In the loop from the exhaust, the water from the condensate will drain, and in a short time it will malfunction. It was good that the exhaust was mounted downwards towards the radiator

Hello Sir, When you put some Enflon tape in a cigarette and smoke it completely up. Then you will get lungcancer. So dangerous is burnt Enflon tape. Hennep would be a better choice in this case. And remove the hennep thas has no use. I made something alike. But i used a bit more modern radiator that has 3/4 inch. I used a PccP version. A plate/convector/convector/plate radiator. Used 22 mm pipe for connection and the heat goes in at the same time in the top and the bottom at the same side and leaves on the other side above. I made 4 x 3.5 inch computer fans and placed them at the underside of the radiator facing upwards. Instead of using 12 volt connected them with 5 volt. That way they turn slower but with less noice. As soon as the radiator at the bottom is 30 degrees Celsius the fans start to turn. Blowing forced air through the inside of the radiator. That way the radiator gives way more heat of in the room. A guess , something like 3 to 4 Kw extra of free heat. The fans run a long time on good powerbank. Be aware that the exhaust gasses have a lot of water trapped in it. Probably in 3 years the radiator is destroyed.

Those laser thermometers measure an average temperature of a cone. The farther then gun is away, the larger the surface it averages. The red dot is just an aiming point
