* On-demand propane units are spark ignition with flame sensor, not pilot.
* CNG woulds still still pump a lot of gas in the boat if it missfired. The firing rate of an on-demand heater is MUCH higher than any other appliance; it heats 4 gallons of water from ~ 65F to 110F every minute, which would take your stove MUCH longer.
* Boats powered by outboards (even some cats up to 40 feet) cannot generate hot water from the engine. We charge batterys via solar.
Mainsail's right; I've seen a few scary installations. These are MUCH higher power than a stove or cabin heater and demand proportionate respect.
