I love the concept, but I'm pretty sure if I ever had anything that looks like that attached to our living room fireplace - no matter how good it works, my wife would most certainly kill me.
Being a guy who can weld and living in a duplex with a fireplace. I welded up some 2 by 2 inch square tubing and used a 100cfm squirrel cage blower. The tubing entered on the left ran across the back and exited out the right side. I built the legs and grate to hold the logs. It takes only 30 minutes to raise the temperature from 60 to 100 degrees. Using the landlord's grate we could burn a fire all day and never get it above 75 degrees. After telling a co-work of it I'm building her one too now.
Sorry, I don't own a video camera and sold it after I moved. It was simple to make though. The grate heated up and air was forced threw it and came out super hot. You can make any shape you want. Metal gets hot, air from room forced threw hot metal equals hot air coming back into room. All combustion gases go up chimney.
My grandparents had something like this when I was a kid. The convection currents from the rising hot are should eliminate the need for the fans. ANd if you cap the top openings and drill a small hole (about the size of a quarter) the restriction will shoot the hot air out further into the room without any need for a fan.
I want to make a heat exchanger to go from a smallish, outdoor masonry rocket heater into a central ac unit. I want it to be passive though, so no water or oil pumping.. I'm thinking that I would have a larger cold air inlet that feeds into multiple 1/4" copper pipe runs that go inside the chamber or wrap around the heater, essentially. Then they run into the unit as tight coils or into a finned heat exchanger, and the exit out the same way they came in.. not sure how well the design would work though
Nice DIY exchanger. Hey could you tell me the best grid tie inverter for the money and where to get it. I am asking you because it looks like you have purchase just about every brand there is. Thanks
if you are running less than 200 watts i would use the 400 watt unit that has the rotating LED's on the front I think its the power grid ll ? you will have to look on the net for them. I will post a video on the 400 watt one because i have it running outside on the porch. and it works much better than the power jacks.
I've been planning a fireplace heating system through every room in the house but starting at this level its excellent to get more heat from the pit but doesn't the blow attract smoke? smoke follows up the chimney with no vent and you're creating vent in your house, try drilling a hole in position you prefer and weld a smaller tube angled to blow smoke upward like a shield barrier and not attract and catch the blow from your design. less carbon, better health. just helping out, I hope your open to suggestions, you might turn work into your own patent product and make money. Cheers.
Hey DIYPV. Do you know if it's better to maximize the number of pipes travelling through the fire or just one pipe with the same gauge the whole way? Also, is thicker better (in order to hold onto more heat and also reset melting)?
yes more pipes would be better jus4 make sure you have good air flow. this was made from a trampoline and I have had really hot fires and the pipes have not saged at all. this will heat the room up fast. Hope this helps and good luck.

Thank you. I learnt that thinner pipes are better for heat transfer. I'll maximise the number of pipes too. I don't have a trampoline but maybe I could scavenge from other equipment.
kunjidee I wouldn't use copper. How were you going to seal the pipes. Solder will melt. Steel piping or tubing is best. Welds won't come apart and steel is cheap compared to copper.
Muffler Pipe works really good too. It's made for heat and if you don't want to do a lot of the work you can have the muffler shop do the bends for you so you don't have to do as many welds. plus, as parts of the pipe burnout you can have the muffler shop make just the part you need cut off the bad section and slide it on
Thanks for the reply. Yes please post that video. I have only 100 watts at this time. The system it will be install on is here watch?v=P555iKNPYzA. Thanks
ferrarigirl666 Actually the fans are not needed, the version I installed has only the tubes and relies on the draft effect to create airflow. it's completely silent and very effective.

😂😂😂
Atleast youll be warm
Get rid of her.....problem solved, you're welcome

Do you a video of your heat exchanger? I would appreciated if you can share even a picture if no video..

Great idea Scott

Could the pipes be dangerous I heard galvanized can give off a gas , someone said they use black pipe instead idk have you heard this?

my fireplace as a couple fans built in, but i would also like something like this to get more out of it.
Nice idea... but what about the noise matter 😮
how many m2 heting with this?
Could run plumbing across the fireplace. Would be interesting.
In 1938 built house the kitchen range included an oven and a firebox heating the adjacent water tank . 😊
Is that galvanize pipe? Galvanized metal can release toxic chemicals when heated.

Nope no smoke the fans are low enough.
Did you ever test it with a decent bed of coals?
The pipes get really hot the air coming out will burn your hands with 2 fans
I think that with one fan, the wind will be slow to pass from the pipes and will heat more. With that speed the air doesn't heat too much.
Anyway to condense that down and make it to fit so it's not sticking out like a sore thumb?
Great idea!!

How did the heat exchanger work out over time?
Still going today, will have to make an update video.
The outlet air is the point!
Where did u get the fans
From an old computer server, they are made of aluminum and are probably 25 years old?
It raised the temp of the air 4 degrees?
that was just a test the unit put out a lot heat
i have a 18 inch fire place you want to build me one i will pay you for it.
Having a real fire with lots of wood would make the test better. I know its an old video but still.
I run it with a full flame and it works very good.
Millionaire idea.
Can this be done with copper pipes? Home depot sells them cheap in 6' lengths
kunjidee I wouldn't use copper. How were you going to seal the pipes. Solder will melt. Steel piping or tubing is best. Welds won't come apart and steel is cheap compared to copper.

What about soft copper?
How well did it heat the room?
It worked great heating the room, puts out a Lot of heat.
Does it ever get cold there? I guess so if you have a fire place. I thought you lived in Nevada or Arizona I dont know?
Arizona, cold to us is anything below 45
We pay about $300 a month in the summer
Thanks for the reply. Yes please post that video. I have only 100 watts at this time. The system it will be install on is here watch?v=P555iKNPYzA. Thanks
what type fans are you using
AC fans
Muito bom!!!
Boa idéia!
cold to us is 50 outside we get use to 110. in the winter we will hit 36 or so and that almost kills us. :}
I come from tx and moved to tn so when it get to winter so any thing below fifty i look for the heat controle lol
Thanks
really romantic with all the noice!

@@footfall4559 Hi, I know this is from ages ago, but do you have any videos or pics of the system you built? Thanks
if those are galvanized they will put out poisonous fumes
Standard steel
50 is cold enough to throw a log on the fire for sure. When it gets below 70 in my house that is getting chilly.
Bad design. So much room for improvement
