Hi, we recently cut back on the propane tanks and are using gas tanks only for cooking.
I know I live in the tropics, but we all like our hot showers, especially at 4am when we wake up.
I came across this video, and it sounds awesome, but I have questions. I wrote the builder (geoff lawton? Daniel Lawton?), and the response was "we have a better design. I'll post it at the end of this year."

However, I'd like to get something going faster.

Anyone available for clarifications, or an even better design?

Here's the vid:

THANKS!

I would also like more info on this. It looks a lot different than the standard rocket heater design. It looks like there is water in the drum and there is a separate copper tube that absorbs the heat from the water in the drum. It seems like an explosion is a real possibility with the set up if there are no relief valves. I would love to no more about it. it would be a great for a radiant heat floor.

as paul in his daily block pointed out, heating water with fire is dangerous. The more automation you put in the more dangerous it is. Unless you have some real experience in things like boiler systems and fail safe devises and plumbing, I would say don't even try. An alternative is to put in a system that heats the water while you wait and then transfers the water into a usage tank that you can monitor the temperature and mix it with cold water for the sake of your skin. you could use a solar heater that heats your water during the day then transfer it into a very well insulated storage tank for use in the morning. There are designs for those systems and they are much safer to use than wood heated systems. Think steam and explosions.

Your right steam and explosions could be a real concern. Our winters tend to be cold and cloudy. That is a terrible combination for solar hot water. That barrel with rv antifreeze and a relief valve is probably pretty safe. Plenty off mass could help stabilize the temperature also. Add in some thermometers in key areas and it wouldn't take long to get consistent results with small quick fires.

As far as I remember the video shows a valve system of some sort.
