How to make a rocket stove shower

How to make a do it yourself rocket stove shower


I appreciate all of the alternative suggestions that readers have sent in concerning our solar shower experiments and I especially liked the rocket stove shower design by Milkwood.com sent in by reader Sarah.

They built theirs in 2 days and I'm guessing the cost to be around 200 to 400 dollars depending on what type of materials you choose.

It's a bit complicated for our current needs, but the idea has got me wondering if this could be easily modified to handle some sort of hot water chicken dunking station which might come in handy if the price of propane continues to go up.

After all these years I still use my old standby, a two quart copper kettle. Uses a minimum amount of fuel no matter what it is. I've used about everything I can think of. When I was on the boat I used a green hand pump pressure sprayer that sat in the sun all day. If it wasn't hot enough then the copper kettle fixed that. If I make it until next winter I hope to make a rocket stove heater. They are so efficient that I can heat my small space with sticks instead of logs. I live in the south but it still gets cold. When I was doing chickens I built a wood fire under a 50 gallon drum. It held enough water that the water stayed up to temperature until we were finished. Never did eat those chickens. Keep on Plucking.

It's so true that it's awfully easy to just throw a pot on the stove and heat up some water. You get used to spending a few extra minutes doing chores that most people take for granted never having to do, and it's no big deal.

For this design to work properly you need the water tank to be higher than the water jacket. Just like hot air, hot water rises.

The pipe returning the hot water to the tank should be vertical, well insulated and run to the top of the tank. The pipe from the tank to the jacket should come from the bottom of the tank.

In general, for thermosiphons you should use wide pipes to minimize resistance. It should also have as few bends and kinks as possible. A thermosiphon central heating I saw in an old (late 1920s) house used 2 inch pipes.

I notice your comment got tossed in moderation. Has the changeover to the new site made you unable to log in?

Great pointers on the design! You helped me understand it a lot more than when I read the original blog post about the design.

When I do a preview, I see my name under the post so AFAICT I'm logged in. Maybe a bug in the software?

The heater at milkwood has a little rise in the hot water tube, so it will work, but the "pump" will not be as efficient as it could be.

Another option for a water heater is to run pipes that transport the hot gases directly though the boiler. This is called a fire-tube boiler. An alternative is a water-tube boiler. Both have been thoroughly explored in the era of steam power. The latter are more suited for high-pressure steam generation because there is less water in the system to explode if the pressure gets too high. Both increase the contact area between the water and the hot gases, making for good heat transfer.

It seems to me that for just heating water a fire-tube boiler is easier to make; drill some holes in the top and bottom of the boiler, stick through some pipes and and weld them in place.

I suspect I changed something in setup when I made the site switch. I'll try to find it and swap it back. :-)

I LIKE YOUR DESIGN HOWEVER I WOULD LIKE TO KNOW WHERE THE COLD WATER INTAKE IS IN YOUR SYSTEM.

One very unique homestead, $1,500 per acre, the opportunity of a lifetime
