Hello Karol,

Thanks for the reply!
I have been thinking about putting the copper directly into the pipe. However there are a few things to say about.
Since you need full heat to have secondary burning in the pipe, I am afraid to lose temperature with the water inside.
Copper is very expensive. After informing several plumbers to ask if copper could stand longterm direct heating they all said no, so it would be a constant cost.
After spending days of watching and thinking about this system, I think I have found my problem. I don't have enough mass around the water to sustain contant heating. After 2 min of burning the stove and than running the water trough the tube, I generate steam and hot water for about 1 minute and than it cools down. I have decreased water pressure, installed a smaller tube (in diameter) but with no results. A conventional gas heater has his copper surrounded by water (very good conductor) wich is used to have more mass around the copper, so it wouldn't cool down that much. (and is used for the central heating system).
What I need is a good conductor around my tube, but that would go directly into the stove principals since it needs a very good insulator.
So now my question:
Is there something that has enough insulating qualities for the stove principals, so I can generate enough heat. But still can give me enough conducting mass around my tube?

The specifics of the copper tube we are using at the moment are; 10 mm inner diameter, 1 mm wall, 15 meters long.

Thanks!

Is this a matter of time? Should we preserve the water we are heating in a tank and send it back over and over again trough the heater till it's warm enough?
Obviously we have to foresee a ventilation point so the tank doesn't explode cause of the steam when it get's too hot.

I understand an instant hot water system is very dangerous to build and should not be tried at home (like this http://www.ecofilms.com.au/rocket-stove-water-heater/ )

Is there a way in the system we're using now to create enough instant warm water? The water runs trough the copper lines at the moment, we are not storing it. So there is no danger in blowing ourselves up.

My brother in law keeps bees and is learning me how to. He told me that bees fly up to 3 kilometres from their hive.

However because of the pollution and insecticides used by farmers here in Europe where I live, they get disorientated and go only up to 1.5 km. Most of the times they can't find their nest back.... It's a big problem here, the bees are ex-stinting...

Hello everybody;

My man and I are working on a Rocket water heater so we can create a shower. However we keep bumping into the same problem with every design we tried so far. Our water doesn't generate enough heat and therefore stays cold.

The design of the rocket stove mass heater works perfectly. We have downdraft and no emissions.

We currently are using 15m of copper pipeline strapped around the heat riser (inner pipe). Around this inner pipe is another pipe slightly larger filled with lava stones for isolation. A large barrel is covering this entire construction.

I will include a drawing of the design we have at the moment. At the drawing the ratios aren't quite correct but in real life we used the instructions written in the "rocket mass heaters book".

Does anyone like to share their opinions/ideas with us how to make this work? We can't figure it out. Thanks in advance!
