Engineer775 has an ingenious setup where he can easily heat water without using any electricity. He made a coil from some copper tubing and placed it inside a stovepipe. The fire heats up the coil to several hundred degrees, and as water flows through the coil, it gets nice and hot. After that, it dumps into his water heater.

One question… How does the water move through the pipe? Does it not need a pump run by electricity?
There is this thing called convection it can be very useful in a closed loop system. Flow can also be obtained via a small circulating pump ran off solar power and battery. Can also be done via A gravity feed system. There are many ways to do things once you step outside the box
Since you are already heating the water..thermoelectric is also an option for producing electricity to move the water.
On the farm we used a donkey to heat water. It was very effective. now living in the city, we are exposed to all types of challenges. High electricity cost, power cuts, water cuts. we are utterly exposed to urban disasters. we need to be prepared.
I want to live off the grid
With the tubing mounted inside the stovepipe, and the water being exposed to “several hundred degrees”, I’d be very concerned about the water flashing to steam. That last thing you need in a prepping situation is a BOMB that kills your family.
Terrific work, did the same for Hot tub but wit larger copper pipe..
years ago we wrapped soft copper around the exhaust on our jeep used two hose adapters and a cheap fuel pump from auto zone two garden hoses and one water saver shower head and nipple later instant hot shower leave the truck running and it was nice and warm for camping trips
Several years ago, my dad set up a coil like this on our wood burning stove in the basement. Worked great in the winter.
No, hot water flows up and cold water flows down so you use physics to cause the water to flow as you like. No generator needed.
Rene and Ron, your comments are rude. The “over-thinking” Rube Goldberg” comments were out of line. Alan was just demonstrating some possibilities for heating water. I for one think his stuff is excellent. Remember, you can always learn something from everyone, even if it’s what not to do.
Wow, what rude comments. Alan was just demonstrating some possibilities. Your engineer crack was uncalled for.
Thats not endless hot water. Gou can only heat up whats in the water heater and when you drain water from the system water has to be added. It would be more sensible and efficient to use the wood fire to boil a potf water. Im sure it will be easier in an emergency to find a large pot rather than a water heater and all the pipe and tubing that is used in the video. Typical engineer, by the time they get done overthinking the situation someone has a simple solution. Lol
Use your head for something other than A hat rack. Thid concept is simple and has been around for years and yes it works well. Cold eater flows in gets heated then flows to the insulated water heater tank for storage. Not that complicated for most people. Apparently your not most people.
Spelling and grammar … the difference between knowing your shit and knowing you’re shit!
I think the idea is preparing. If you have it already, no need to scramble when an emergency happens. That’s the concept behind prepping.
On a side not, a pot of water heated causes water loss due to evaporation, this process contains that evaporated water in the water heater, so no water loss. Also the fire could be used for cooking and keeping warm while heating the water.
A tip for those that are not prepared. Your house has all these materials built in, all you’d have to do is dig them out and piece it together. That would be an extreme life and death situation though.
Just food for thought.
You are a dick head Ron.
Go find something to do that will impress us since you consider yourself such an expert. Perhaps cure cancer, then maybe we will consider you as something to recognise.
WTF? You’ve got no electricity because of a major storm – so you want to fire up your wood burning L.E.A.F. gasifier generator to run a fuel powered electric generator – but to get the L.E.A.F. generator to fire up and get a good head of heat, you need and electric blower to get it going !?!?!? So where is that power coming from to run the Blower in the beginning? LOL… It’s a RUBE GOLDBERG invention!
It’s called a rocket stove. Has been proven over and over in alternative energy books. You just need to know HOW to incorporate it.
