Major issues with the hydro flame in the camper DOH!! no problem, I'll just put my spare in. Doh!! major non repairable gas leak $$$$.
So after much research i decided to go with the Fatsco Tiny Tot. Small round cast iron. Only one issue, can't get one here before late January. Not soon enough, as our entire Christmas holiday is based on the camper being operational.
So given the fact that I am a fabricator for a living, I will just build my own. 6 x 6x 1/4" HSS 12" tall will give more volume then the Tiny Tot in the same amount of space. I can improve on their design by adding a vent to pull combustion air from outside instead of from the interior. And I can add a baffle inside to retain more heat also help keep the flue from getting too hot. Doors will be made from 1/4" plate so no warping there.
We plan to install it in the center of the camper, so it should be easy to distribute warm air around with a couple small computer fans
Got a good start last night as I have only one week to build, test and install it in the camper. All that's left for this morning are feet, hinges, and door seal.
So if all goes well, we will no longer be depending on Batteries to run the heater!
