Anyone know much about hot water heaters?

My wife and I (no kids) just bought our first house 5 months ago (3 bed, 3 full bath). The house is almost 3 years old. The house has a 40-gallon electric water heater. We are about fed up because if my wife takes a bath, I cannot get thru a shower without running out of hot water, if I take one immediately following her. I know there is nothing wrong with the water heater, so I guess we are gonna have to upgrade. The master bath has a jacuzzi tub (which we've never used), and we can't even fill it without running out of hot water (it's being fed by a standard Delta faucet). What we'd like is to be able to fill the jacuzzi tub, and still have enough hot water to follow that up with a shower.

Should we add another 40-gallon, or should we replace the existing unit with an 80-gallon?

Or should we go with a tankless unit in the master bath?

What would you do?

I'd look into adding a tankless unit. Adding tankless units are much easier and cheaper in the long run.

40 gallon sounds small for your needs, and you could consider getting a bigger one instead if it might be cheaper. I don't know about adding another one beside the existing one, seems weird.

I can get an 80-gallon Whirlpool electric at Lowe's for $268 with the following specs:

* 2- 4500W, 240V Elements
* 20.7 GPH Recovery
* .87 Energy Factor

There was a thread here a few weeks ago about hot water heaters. I posted a site for a Japanese tankless water heating system.

I know I wouldn't waste my time heating hot water. Sounds redundant.

When my wife and I bought our hour 5 years ago the water heater broke after a few months. It was electrical. I just went and replaced it with the biggest electrical one that Home Depot had. it was probably like the Lowes one listed above unless its 60 instead of 80.

Take a shower before she does. Problem solved. My wife uses the water heater as a timer. When the hot water runs out, her shower is done. I don't know what she was doing with the water yesterday, but my shower was fairly cold. She took one after me, and was out in under two minutes. That's got to be a record for her.

How is it working out?

No natural gas in the area? A 40 gal. gas water heater will best an 80 gal electric.

You might also check to see how hot it's keeping the hot water, and turn it up if it isn't "really hot". The hotter the water in the heater, the less you use for a shower or bath, though you spend more to keep it that hot.

On demand and "Tank less" Water heaters are nice... but keep this in mind

If there is ever an emergency - and something happens to your water supply your water heater tank has 40 gallons of water for you to drink. That's why I will not switch.

So does my neighbors water heater tank. And I have ammo.

Seriously, if you want to store 40 gallons of water, go buy eight 5-gallon containers and shove them in a corner in the basement or under the house or in the attic or something. It ain't going to spoil or anything. No need to continually keep 40 gallons of water hot just for possible emergency uses.

I like the tankless idea since I could just have them install in under the counter or something. I don't know much about them though. I wonder where a good place to buy them would be.

Last year we got a new 50 gallon gas water heater. We can now do a load of clothes, run the dishwasher and each take showers at the same time and we never run out.

If your hot water heater is in the garage and you live where it is cold, a water heater blanket might help and even save some money.

If you get a new hot water heater and it is in your home, I'd really see what it would cost to install a pan under it.

There are two elements in a water heater. One on top, one on bottom. If one is bad, the water will run cold sooner than it should. You can tell by disconnecting the lead wires from the element and then read with a meter between the two electrical contacts on the element, if they are shorted the element is bad. You can buy another for $20, drain the tank, then replace it.

By the way, I just got my new Consumer Reports and they have a couple of pages on water heaters, it might be worth buying or stopping by the library (or stopping by a bookstore) to see.

my parents have a tankless gas one
takes a tad longer to get hot water when you turn the faucet, but it won't run out. plus it only comes on when it's being used
a tank will come on and off all the time, costing you money in utilities
