Someone please explain my hot water problem..

Ok. So I like to take VERY hot showers.. I'm usually the first one to take a shower in the morning and every so often I will crank the shower all the way and it still isn't HOT. Now, I'd say 25 out of 30 I turn the shower on and have plenty room to turn if I wanted to scald my body.. But then there's the 5 times where I turn it all the way and it's not even hot enough.

Now, the times this happens my wife isn't taking a shower before me so I don't think the hot water tank is empty..

We have VERY hot water in general..

So.. What's up??

The elves are sneaking in and using up your hot water at night.

Try not running the cold water at the same time.

Perhaps the thermostat(s) on your water heater aren't working properly.

I used to have this problem. Sometimes you are taking a shower at about the same time the hot water in the heater reaches the lowest temp before the burner kicks on.

Example if you keep your hot water heater at 130 the water may heat to 140 then cool off to under 130... when the temp reaches 130 on its way down, the heater will kick on.

Therefore, you just catching the water heater right before it is kicking on.. or at a point when it is on - but your shower is causing more cold water to rush into the tank, which is cooling the water even more.

You say you "used" to have this problem. What'd you do to fix it?

It sucks!!!

I guess I could do that but it's already pretty high. I mean if I'm washing the dishes I sometimes dang near scald myself..

Also, would that raise my gas bill? That would it cause it to be on more right?

I put in a 90 Gal Water heater that uses the furnace to heat the water - rather than having a burner on the bottom of the heater

It's called an Indirect Water Heater

You don't need to get a huge tank, but the water heater is the key.

That's what I do. Hotter water cleans clothes better and washes dishes better. Plus it uses up more dead dinosaurs.

So this eliminates the current water heater?

Well you still have what looks like a water heater there, but there is no burner on the bottom of it.

So the tank is there, but your furnace heats the tank that the hot water is stored in.

Up! Still having this freaking problem and it seems to be more consistent.. I didn't do absolutely anything yet but I figured it'd see if anyone has any new ideas. I DO NOT want to turn up the temerature on the water heater because we now have a newborn and I don't want to chance her getting scalded (as I said the water is already VERY hot when it IS working).

Thanks!

We told you what fixes it. Turn up the temperature of the water heater.

Tip: Check the temperature of the pot before putting your baby in it.

Like I said.. The temp is already VERY high because it comes out SCALDING at times (no joke).. So is the solution to really just turn it up even higher?

Just get a new water heater. Your current one sounds like it has a sticky thermostat.

The only alternative might be to run some hot water 20-30 minutes before taking a shower. You said it doesn't happen on days that your wife showers before you. Your thermostat has a "cut on" temperature when it gets too cold and a "cut off" temperature when it gets too hot. On the days you have this problem, the water is probably right above the "cut on" temperature.

If you run some hot water before your shower, it will bring the water temperature down, causing the water heater to heat up, guaranteeing you a hot shower.

I'm not an expert on water heaters, but I do intend on reading the Wikipedia article on them at some point in the future.
