I recently purchased a second home that has a propane hot water heater installed in the garage. It has a pilot light and I don't like having it in the garage with possible exposure to gasoline fumes. I also turn the thermostat down when I'm not there, but not off since it is a pain to relight the pilot light each time I return. Even at this low temperature it seems to use a lot of propane.

I'm considering two alternatives for its replacement and would appreciate the advice from anyone reading this forum.

1) On demand propane heater installed either in the garage or on the exterior (South Carolina location).

2) Electric heater that could be turned off when I am not there.

Usage is for a family of three but up to 10 when friends are there.

Is on demand electric also an option ??

Any advice would be appreciated.
