The easiest way to supply a Wave Heater with propane is to have a supply line plumbed into your RV’s current propane system, thus allowing the Wave to use the identical propane supply as your other propane appliances (stove, fridge, water heater). But to do that you both should be really comfortable with tapping right into a propane line, or find someone who knows what the heck they are doing. The ‘plumb into current propane system’ is the choice that Camp Addict Co-founder Kelly uses with her Wave
official Alpha Heater site and works great for her. The second best possibility is to buy a hose that attaches to a portable propane tank (20 or 30 pound measurement) and use that as a gasoline supply. You're supposed to maintain the propane bottle outdoors and run the hose into your rig, connecting to the Wave Heater. Depending on what kind of RV you may have, and access to the skin, that is handled in a different way. So I can not converse to your precise state of affairs. Using a small green propane canister with a Wave heater isn’t the best of concepts just because they're expensive and don’t last long. While theoretically it can be achieved if you can discover a hose that works (I don’t know of 1 off the top of my head), I think you’d discover one in all the primary two options a lot nicer in the long run.
