I understand that you don't have enough electrical power to install an electrical heater, but I would be very careful with installing a propane system. For all the reasons mentioned above I have decided no propane will be allowed on my boat. No stove, no oven, no grill, no water heater, nothing.
My water heater works in a double function. While the port engine is running the cooling water of the engine will warm up the boiler and when the engine is not running it is AC power that will do the trick. Normally we have the boiler off during the night and we take a shower right after we arrive in an anchorage. Then the water is still warm, no need for electrical
It uses about 1100 Watt at 220 V for about 20 min to warm up enough water for a shower. At 24 V that is about 20 Ah out of the batteries, which is acceptable. 4 of my solar panels alone already deliver about 80 Ah with very little sun, so I don't need to start up the generator at all.
I have 4 additional panels, but left them out of the equasion.
