water heater with Direct Spark Ignition (DSI) needs a small amount of 12V DC power just to run the controls and make the spark that ignites the propane flame; the heat comes from burning propane. A heater with DSI doesn't have a pilot flame.
Propane heaters with pilots - such as the one in our 1979 Boler
- don't need any electrical
power at all to operate. I would still choose DSI over a pilot every time!
Most of the options discussed so far in this thread are not propane-fired at all - they are various styles of electric heaters than run on lots of 120V AC power.
