If she runs out when she showers you might want to install a lower gpm shower head. Maybe you need a larger water heater with that bathtub and forgetaboutit.
The biggest issue is running out of water when taking a bath (large jetted tub), but if she takes a longer shower, she will run out as well.

What benefit is a powered vent? I don't have any horizontal exhaust sections.


I measured the tub and a rough estimate is it is about 100 gallons. So after thinking about it more, I am leaning towards just going with a 75 gallon with a higher recovery rate?

Another options would be to go for the 50 gallon and add in a Water Heater Booster which would probably be cheaper than a 75 gallon tank. Also has the added benefit of not turning on unless needed so I'mm only be keeping 50 gallons of water hot instead of 75 and the booster will only turn on when needed.

Re: Should I replace my 7 y/o Water Heater?


the bigger the tank, the lower the surface area to volume ratio. seems a bigger tank > small tank + high cost electric add-on.

Look into a power vent and what it takes to install. The recovery time is much faster.

Re: Should I replace my 7 y/o Water Heater?


clawlan,

I hope your water heater situation works out better than mine.

You raise a point that caught my attention: hot water running out from the heater.

I was just curious whether there's a way to tell between a "normal" running out of hot water (if there's is one) and a "problem" situation (meaning the hot water is running out because there's something wrong with the heater).

What happened with your water heater?

I am 90% sure the heater is functioning properly because she runs out only when taking a long shower or filling the tub. It's a 100g tub and while I don't need a 100g of hot water clearly, I'm still afraid that 50g might not be enough for her.

Re: Should I replace my 7 y/o Water Heater?


Thanks.

Another question (again, this is meant for anyone interested in responding): If one lives on the 3rd floor of a building (with a water heater located in the basement), and turns the shower on in the morning, I presume it's normal to expect the hot water to take a while to arrive in the shower (especially in the winter), am I right?

If I'm right, I wonder what's a "normal" wait time and a "problem" wait time. Just curious.

My water heater is in the basement and the master bath is on the 2nd floor. I never timed it but I'd estimate it takes 2-3 minutes for the hot to make it full force. Maybe I'll time it when I take a shower next.

At our residence wait time is approx. 20 seconds for 20 ft. of 1/2" pipe and about 3 quart of water flow .

SeniorSitizen,

Your answer and that of clawlan very interesting! But I don't want to read too much into it unless I have more proof.

Are you sure your hot water arrives that quick?

With me, when I had my previous water heater (the one that worked as opposed to my current one), it took a bit for the hot water to arrive. I wish I had timed it. Also, hot water sometimes ran out but when I turned off the faucet and turned it back on, I would get hot water. I just assumed this was normal.

After I started having my water heater problem (with my new heater) I asked my neighbor on the 3rd floor, with whom I share plumbing, about her hot water experience. This was her response:

"My hot water also takes a few minutes to arrive because two floors of water standing in the pipes has cooled and has to be flushed before the hot water can arrive. But I donít have a problem with the hot water cycling on and then going cold."

Does this sound correct or could it be a problem that we're not aware of? Or is there no way of knowing? Just curious.

Hey stripped leave this thread alone. You have had one of the longest threads on here with many questions about your situation and had expert advise. It's time for you to pay the piper. Either call the plumber back to repair your system or hire another plumber to troubleshoot and repair your water heater problem. This guy has enough problem's without your problems. Stop stealing his info your problem is not related to his. Time to pay up. I am starting to think you installed your water heater yourself and are trolling for answers. Call the PLUMBER that installed your's.

Coldiron,

You could not be further from the truth when you say I may have installed my water heater myself. I have too much respect for this forum for me to try such a stupid trick.

But how can I prove that?

Anyway, I won't argue with you.

Whatever I learn from my plumber I'll let you know.

Regardless, thread hijacking is poor form.

Re: Should I replace my 7 y/o Water Heater?


So I've been thinking about it more and researching a ton, and called another plumber that came highly recommended, and now I am leaning towards tankless. The cost of a 75 is approaching the cost of a tankless unit, and while the install cost is definitely higher for tankless, it's still under my original budget. Some other positives of tankless is I won't have to worry about 75g of water leaking into my finished basement should the tank have an issue, won't have to keep 75g hot all the time, and I won't have to worry about running out of water when we have guests staying over in our large 5 bed 3.5 bath home.

In addition, we have pretty soft water so that reduces the scale buildup issues.

Sure the payback period is longer than a 50g or 75g tank, but the benefits are worth it to me. I'll let you all know what route I take!
