I haven't done any sums but usually turn the water heater off overnight so we don't hear the click as it comes back on. I suspect it saves a bit of gas but not enough to get excited about. It doesn't heat up from cold as the water in ours is still hottish in the morning but it is in an enclosed insulated space.

I don't know about the economics but we always turn the water heater off as soon as we are finished with it. It would only run for about 2-3 hours in total every 24hrs.

I only turn it on 15 mins before it's needed and turn it off before 2 showers and the dishes get done. There's still warm water left after that.

The insulation on those Suburban water heaters is nowhere as efficient as a household unit judging by the warmth you can feel around the unit and in the cavity it lives in so I suspect it is cost effective to turn it off when not in use. We turn ours on around 20 minutes before morning showers so no great shakes turning it off.

We only turn the water heater on in the morning. Have a cuppa tea and read a another chapter and the water is now hot enough to ablute and wash the dishes from the previous night. Then we turn it off.
It's an Attwood unit. Used this way the 9kg gas bottle lasts about 28-30 days ( it is also being used for cooking)

We've got an Atwood (manual lighting) which we fire up as soon as we park and leave it going until we're ready to break camp. Once up to temperature it very rarely heats again until we've used some hot water. The pilot flame seems to use very little gas and probably helps to maintain the heat within the storage cylinder anyway. This way we always have hot water whenever we want and our 9kg LPG lasts for ages. Most of our gas usage is for cooking and running our heating system.

We have a Truma.
Turn it off at night.
Wake up, have a pee, turn hot water on, go back to bed.
Snooze for 20-30 minutes.
Get up, shower, breakfast, do dishes, turn hot water off, go travelling.

P.S. There's no such thing as a dumb question.
