Quick question;

When we go away for 3 days then come home, why is there only warm water? Isn't the tank supposed to keep it hot? The kids hate taking baths when we get home... definatly not comfortable!

Any other time there is plenty of hot water.

ps. Gas heater.

The built in thermostat may be getting sluggish for some unknown reason, perhaps age or caked up sediment on its probe in the tank.

(easier for gas heaters) Slowly turn the dial up a few notches and then slowly turn it back to where it was. You may find that the heater cycles on and maybe 15 minutes later shuts off again. Now the water should be nice and hot.

If the heater cycles back off as soon as you turned the dial back where it was, the water should still be hot. Don't turn it up so many notches the next time you tweak it. But you can choose a higher setting to leave it at for all time. You don't want to have it cycle on and off in short order too often; you may shorten the life of the heater.

I would not leave the dial in the "very hot" range even for a few minutes.

Depending on the age of your kids water should be at least 125 or if kids are old enough not to burn themselves 140. Adjust temp dial accordingly.wait till unit cycles off before reading the temp with a thermometer
not sure about previous posters scare about leaving it on very hot thermostats lose there accuracy over time very hot when new was only 140 now it might be only 130
the premise here the hotter the water starts out, the less hot you use and more cold to temper it so thusly providing you with a longer supply of hot water

I had the same problem, I think it has to do with corrosion/scale building up on the sensor. I dd not bother to try to fix mine as the WH was 18 years old, I just replaced it. I did pull the sensor out once I installed the new just out of curiosity; it looked pretty corroded.

If you do daycare in MN you are not allowed to have your water set over 120*. My wife did in home daycare for over 18 years.

No. Let me try again.

If I use the bath, shower etc. daily: it is perfect. Hot water every time.
If I leave for a few days, say to go camping, then return and want a shower: the water is warm at best. Next mornign it is fine.

Almost as if it goes into "sleep" mode when I leave town, and when I use it regularly it is in active mode.

Every water heater will gradually cool down between cyclings of the burner or elements.

Yours just doesn't kick on again before the water gets really cool.
