New water heater, hot water doesn't last long.


I just replaced my 50 gallon gas water heater with a new GE 50 gallon gas water heater. I had to turn the thermostat all the way up. When I start a shower, the water is nice and hot. Less than 2 minutes into the shower, the water slowly gets cooler and I have to shut off the cold valve completely in order for the water to stay some what hot/warm. I called the technical service phone number and they're telling me that it sounds like it's operating correctly. My old water heater used to put out very hot water for a very long time and the thermostat was only half way turned up.

Any suggestions on what might be wrong??

The first thing that I would check is that the in and out plumbing is correct; cold water supply, from the street or well, should be connected to the port marked "COLD", and lines carry hot water to the points of use should be connected to the port marked "HOT".

That was the first thing I checked. They are connected correctly.

Who installed it?

Does this happen only at the shower, or does the hot water run out fairly quickly at all the fixtures? Run the shower and wait for it to get cool, then check the sink (hot only) in the same bathroom.

If you have a thermometer that can read between 100-200 degrees F: Get a temperature of the water coming out the hot side only.

Are you sure you didn't turn the thermostat the wrong way?

I'll check the temp with a thermometer when i get home from work. Pretty sure i turned the thermostat the right way, the arrow is pointing on the label that says "VERY HOT"

I installed it. seems like it's only happening in the shower, but then again i don't think i've left the hot side of the sink on long enough to find out. i'll try that when i get home from work and see what happens.

Sometimes when you install a new water heater, scale and rust can flake off the inside of the pipes (where you're working) and find it's way into things.

Is it natural gas or propane?

Was thinking of checking the dip tube, but that should not be a problem considering it's a brand new water heater.

Is this a high efficiency heater, vented to PVC pipe with a blower on top, or just a standard hot water heater, vented into a chimney flue? Nice if you give enough info to attempt an assessment.

Sorry. Nothing vented to PVC. It's vented into a chimney flue. GE Model #: PG50T09AVH

This would be my bet.
It wouldn't be the first one to have a bad dip tube right out of the box.
It very simple to replace.

Thanks D. I was planning on checking that out first thing after work today. Hopefully that's all it is. If not, it's under warranty so I'll let GE handle it.
