You save the cost of the heat that did not escape because of the lower temp. It does not take more energy to re-heat the water after cooling, which is more efficient at transferring the flame energy to the water during the time when the water is cooler, and drops as the difference between the flame temp and the water temp lessens.

Or, in reality, it is a cold water heater.

Obviously, it will run more often until the house itself is warmed more, but you still saved the heat not lost because the house was cooler.
The only real issues are if erroneously you crank up the heat higher than you want it because it is cold, and it might take longer to get it warm if you have a heat pump or other system designed to heat most of the time to keep the house warm.

Oh, one thing I forgot. Is there a loss? That depends on the season and where the water heater is. If you have to put some heat into the building anyway, loss from the water heater is just a contribution from a different source.
Often, utilities are in the basement or a closet off the living area. In summer, a potential burden in winter, a good contributor.

Yes!

Well, there will always be an energy loss if the ambient temperature is lower than the temperature at which the hot water is stored.
I agree, you may not 'count' that loss if the heat escapes to an area that you'd like to keep warm - like a basement living area in winter. However, in the UK electricity is 4 times the cost of gas. It's very rare to find a home heated by electricity here - althought that's starting to change as more people install air source heat pumps

The term "hot" describes the temperature range from ______ºF to ______ºF.

THAT's the kind of question I was asking.
a. Turning off the well pump just protected me from catastrophic loss of water in the large storage tanks in case a hose blew.
b. But I had also turned off the water pressure booster pump.
c. So I was wondering if the water slowly leaked out through garden hose drips or toilet drips or any other drip...
My question partially included what you said, which is...
What happens when a (cold) water heater has no water in it and the pilot light and temperature is set at the normal levels?
Does a (cold) water heater have a volume switch that turns it off?

Mine is piezoelectric. So you turn on the propane gas valve (the propane company fills the 1000 gallon tank once a year), wait a few minutes for the
2psi (or whatever low pressure it is coming out of the regulator) to get to the pilot, then you hold the pilot light down for about 30 seconds and snap the piezoelectric switch a couple of times, and you wait a few seconds for the thermocouple to heat up which turns on the gas to the boiler and then you turn the pilot switch to the full-on position and you can hear the flames whoosh.
You're supposed to bend down on the garage floor to look into the sight glass but I don't bother because hearing the whoosh is all I need to know.
Then you wait about a half hour and you can take a shower.
As I said, it's no bother but if that is a bother to someone, then just fixing a hose would be a far bigger bother to them if a garden hose leaked.
Yes. Exactly. Well almost exactly as I live in the boondocks so I have to supply all the basic normal utilities except electricity and POTS lines.
I have old garden hoses and sometimes they spring a leak and that could drain my entire water reservoir of a few thousand gallons to the fire line.
Which is why I shut off the water pressure booster pump and why I shut off the well pump (no sense filling a water storage tank just so it can leak).
Many people live in cold climes but where I live, we never need heat.

Oh yeah, heat pumps. I hear they take forever to get a house warm.
I wonder if that applies to heat-pump water heaters too.

In a rental car. One other person at the Zoom meeting noticed I was in a car.
My car was in it's parking place.
that I think had once hung on the doorknob.
Real men kick the door open. After all they hadn't seen me for weeks. Seconds were precious.

You save a lot of money if you get a hot water heater. If, say, you only have to raise the temperature 2 to 4 degrees to take a shower or bath, that costs much less than raising it 50 or 60 degrees.
