We use one of these. (And have a spare for less than $250) Plenty of heating flow for a shower. (1.5L) Ignition and safety controls use 2-“D” cells. Burner isn’t any bigger in BTU’s than a standard propane oven so no need to vent outside. Just add batteries and propane..

2 quality “D” cells will last for over a year. I use a standard grill propane tank/regulator system for the propane supply. 2-3 showers/day and the tank will last ~3 months. No need to impose on the solar system..
