Deek’s Veggie Oil Heater

Hey Kent,

First off, thank you for this opportunity as guest article-author on your blog, and and additional thanks to yourself, and the others out there (Janzen, Kahn, Stiles, Pino, etc) who have been very helpful and supportive of what I’m doing (in regards to my 100% independent tiny housing book, and video/tv show).

As for the “Tiny Yellow House” series on youtube, the vegetable oil space heater (woodstove alternative) that was briefly shown in Episode #2 http://www.youtube.com/watch?v=LmR3kx660gw is something that I understand you (as well as I) have gotten a ton of email questions on.

All in all, since its rather difficult to just blurt out every constructive detail of the heater, I’ve sent you a hand sketched diagram of it instead, that was drawn as part of my follow-up to the book “Humble Homes, Simple Shacks…” which I’m still working on as we speak…er…as I type. The sketch, albeit busy and detail laden, should help give people the general idea I came up with, and I’m sure there ultimately will be twenty better ways to build this thing. All in all, while using a multi-wick system (more flames = more heat), this veggie-oil heater gives off a rather decent amount of heat that should be adequate for well-sealed tiny cabins, or should at least prolong your season or stay in a cabin, depending on your climate, naturally.

Mikes Solar Hot Water Heater

The other day I showed you Mike’s Micro House which he has been building for under $3,000.

Mike is also quite an inventor and is interested in solar and wind energy. He has created a simple hot water heater that I think would be useful for a tiny house or a large home. I asked Mike to share the details on how he creates his solar hot water heater.

Solar water heater. Sun during the day preheats the water in a 30 gallon water tank, prior to it being sent into the on demand water heater inside the house. This solar heater has preheated the water up to over 100F more than once when the outdoor temp was in the 30F range.

This simple setup works great, and is pretty much maintenance free. Just keep the glass clean, and you are good to go. If it starts to warm the water to hot during the summer months, just cover a portion of the solar window, to lower the sunlight bombardment into the solar chamber.

The solar water heater is simply a standard water heater (preferably one that was electric not gas powered).

Here’s what you do:

  1. Peel off the outer sheetmetal skin of the water heater, and cut off the foam insulation in order to get to the internal steel tank.
  2. Remove the electric heating element if needed and replace with a simple pipe plug fitting if the original element was bad, causing a leak.. Otherwise do nothing but remove all the electrical wiring to the element and the thermostat controls.
  3. Verify that the overtemp/pressure valve operates and looks to be in good condition, otherwise replace it, so you have a safety feature if the pressure were to build up to high from the heated water.
  4. Paint the water tank, “Flat Black” in order to help it absorb more of the sun’s energy.
  5. Build an insulated enclosure that the water tank can fit into, with a window on top at roughly a 45degree angle.
  6. Place the tank in the enclosure so that the southern sun exposure will shine directly onto the water tank inside.
  7. Plumb the cold water going to your existing home’s water heater to the input of the solar water heater, and the output of the solar water heater to the original cold water input of the original home water heater.

Now when the sun preheats the water in the solar water heater, it will be feed into your home’s existing water heater as hot water, therefore your now backup water heater should not work nearly as hard to provide hot water for your home.

Kandle Heeter Candle Holder

Doyle Doss has been living “tiny” for almost 30 years. Mostly in one travel trailer or another usually set in pristine and ideal locations. Presently he in a 35 ft 5th wheel, that’s running at 280 square ft — more space than he is used to, but it is nice. He shared with me a unique little heater that will work great in small spaces.

Kandle Heeter

The Kandle Heeter Candle Holder, is a steel and ceramic radiator assembly that sits above the candle and converts the thermal energy of the candle into dry radiant space heat — very effective in small insulated space.

The heater is also available in a very low wattage electric version using either a 50 watt infrared lamp or a 60 watt quartz halogen. Visit the Kandle Heeter site and learn more.
