Furnace drained and drained the battery. Solution: Wave 3!

You would be correct, I have not investigated the Wave heater specifically. So let me ask you this, is it unvented as in the flue gases spill directly into the conditioned space? If so, do the flue gases contain C02?

CO2 and water vapor. With the myriad of Alaskan Kush plants in my truck camper, they will soak up the water and CO2, and produce O2, for both me and the heater to reingest. It's a viscous, satisfying heady life circle. :)
