Eddie’s amazing Rocket Heater

The Cantina area of Eddie's and Val's home is just under 1000 square feet, uninsulated mostly.  The wooden doors open to a patio and you can see daylight through them.

Hi readers.  Thanks for coming by for a read.

Last year when I visited here Eddie and Val were heating The Cantina with a fireplace and a propane heater kicking in when things became uncomfortably cool.  He was troubling himself about the price of having Mesquite firewood hauled here.

This year it’s an entirely different matter.  During the summer months Eddie researched the rocket stoves being utilized in 3rd world countries, turning out an amazing amount of heat on a few twigs.  Finally, he altered the designs somewhat and built one from a scrap pressure tank for his well, mortar-mix Vermiculite for the heat concentration, and a small firebox constructed from stovepipe.

The fuel?  Free pallets from the local businesses.

Total firewood requirement to keep the Cantina warm for the coldest week thus far in 2013?  Three pallets.

This past week was the test.  Temperatures below freezing for a week.  The Cantina was toasty all week, and all week long they awoke to comparative warmth in the Cantina despite the fire having been out for hours.

That perpendicular piece of stovepipe is the firebox.  Eddie's redesigning it somewhat to make for easier cleaning.

The exterior appears fairly commonplace.  It’s inside where the Secrets of fuel economy reside.

What appears to be concrete is a hardened mixture of mortar mix, vermiculite, and stovepipe ….. wood ash mixed with the mortar/vermiculite to provide stability when the pipe melts or rots from the center.

  1. If this works so well, then why…is this not well-known? (particularly the altered design etc).

  2. cool… how much $ does it take to make?

  3. Eddie’s definitely a clever young man. J
