New project. We will be heading out this summer for Teddy Roosevelt, Tetons, and Yellowstone National Parks and my "plan" (subject to change with out notice) is to head out in early June and while we have the Espar diesel heater, it and its fuel tank take up precious room.
We have a 6 gal water heater and I was thinking of using an old heater core I had (or thought I did) in the garage and setting it up with computer case fan and 12V solar hot water pump to provide some heat, we do not need much.
I have watched a number of episodes of "Hoarders" to inspire me to clean and the old heater core was one of the victims. I am however not sure that is a bad thing because it was soldered and old enough to have been with lead solder and it was a lot less than clean, and likely contaminated with antifreeze. I purchased a new aluminum heater core and am getting ready to order the pump and make a housing. I will write it up as I go along.
