I will show you how to build a cheap and easy water heater to use for camping, hunting cabins, or anywhere that hot water isn't readily available. I have also include pictures of my finished product. I travel a lot in my motor home and don't like using LP Gas so I tinkered with some materials and came up with this. All in-home water heaters use a lot of energy but the one I built uses less than 1200 watts (10 amps). I wouldn't recommend using this in a house unless you modify the directions as standard houses use water pressure (town water or well). When I camp out, I take a 1500 watt power inverter and hook to my car battery to heat my water. I went to Wal-Mart and purchased a shower tent and used cpvc to run into tent and put a valve and a shower head on and it's ready to go.
Step 2: Step 2
On this step, you DO NOT have to take the reservoir off of the coffee maker. You do have to drill (2) 3/4'' holes in the back of the coffee maker to re-route the water lines and you have to take the bottom off the coffee maker to disconnect the old lines and hook up the new lines. (See Picture in STEP 13)
Step 10: Step 10
As you can see here, I have the modified coffee maker sitting on top of the barrel. I drilled an extra 2 holes in the space that the coffee maker is sitting just in case the hose(s) were to leak from the element and the water will go back into barrel and not onto the ground. Mine hasn't leaked but it is always better to be safe than sorry. Don't mind all of the cpvc pipes and valves as I just put together using what parts I had at the time. I started with using water heater for the shower, then added another line to run to the kitchen sink.
