Like I said, you have to have a good inverter system or generator when moving. The heads can be 120v or 240v. I have one of each. but like the 240v better, smaller wires, about 6-7 amps per leg. If you're on a lake you probably don't need the marine version. Toilet has a coated paper liner used each time. It carries solids or liquids below to the burn pot without spillage. The liquid is evaporated. The burn pot runs at 1000°F and cycles on and off as needed. So the power use isn't continuous. It consumes about 1 kw per cycle. So a small generator would have no issue running it. If you go to their website (
https://incinolet.com), you can see the ash pan/burn pot. They have a parts section, but like I said, with 2 toilets in about 10 years, I have had no parts failure. Just the liners, about 7¢ a flush, last time i priced them.
All fumes/vapor passes thru a catalytic converter that is outside the electrical coils. The exhaust is thru plastic pipe, so the pipe temp is cool enough to go thru wood. My toilets exhaust 2 decks above on the flying bridge and exhaust to the side. It's rare to catch a whiff of burning, but if you do, it's a common burn smell, not sewage. The blower within the toilet is quieter than a usual bathroom vent. The ash needs to be removed about every 5-10 uses. It's clean, no smell, only light grey ash in a stainless bowl. Besides occasionally wiping down the toilet and seat, the only big maintenance chore is removing the blower about twice a year and cleaning the wheel vanes. The wheel is stainless and cleans easily or can be left to soak in a detergent solution.
I went to this toilet instead of a marine toilet because I didn't want a holding tank, considered a MSD treatment system, and was aware of all the no discharge zones being proposed when I bought my current boat. I decided to make 120/240v AC available all the time and that dictated the inverter and battery bank I installed. The boat came with 2 generators.
The times I've rafted with friends, people prefer to use my toilets over their own marine toilets, especially the women. There's no smell and almost no cleaning compared to a house toilet. When I'm on the boat alone, I have a urinal in the fo'c'sle, so no splashes to wipe up.
A lot of generators have a sensing circuit and automatically start when some appliance or light is turned on and shut down when the load is off. I don't use the sensing circuit because of the inverter. Everything runs thru the inverter. If power fails at the dock it switches over to battery. If the battery bank gets low, it starts a generator. Underweigh I have a alternator on the mains dedicated to keeping the inverter bank charged so I don't have to run a generator if the mains are running.
