Only disadvantage I found is no hot water if the power goes out

You say that now. Tankless here. When Issac hit we were without power for 5 days. Went to take the first shower and the water was like ice. Everyone in the house ended up having to sponge bath because of it. BIG downside.

Waltet White endorses tankless.

What are the advantages of tankless over standard tank models?

Even still, in those times there are much more pressing needs. Having water PERIOD is great. We didn't for a couple days with Issac. I have no problems with a sponge bath cause you get all sweaty right away, anyway. Heat some in a crawfish pot. We have nat. gas and also have several bottles of propane.
BUT, how often does that happen, anyway? Definitely worth the trade.

you do know tankless heaters are available in gas just like a tanked heater.

They generally require electricity to light that gas.

Also, endless supply for multiple showers/baths.
I don't have a tankless but wish I did.

Ok, so I have all gas except for clothes dryer. My gas bill during the summer is ~$20. So how much would I really be saving if I'm only spending $10 on gas monthly for water heating with a regular model.

To put it in our home would require, I was told, mounting it on an exterior wall???

To answer your question, I don't know, I don't have one.
Posted on 1/18/15 at 12:55 pm to Geauxtiga
No, I'm just asking in general. When I build, I'll have to decide this. I'm going to have gas and want to make the best decision. I'm not seeing many advantages other than they're the cook new thing.

That would probably be the water already in the line between the heater and outlet you're using...like with a tank.
I don't think so. She had a tank water heater before she replaced it with a tankless. It takes a noticeably longer amount of time for hot water to start coming out.

Originally, we planned tankless for our new home, but after much discussion with contractor and plumbers (one is BIL in another state with no skin in the game) we decided against tankless.
Much higher initial cost was one factor against tankless but also maintenance and reliability was also a concern.
Instead, we will run two 50 gallon tanks in parallel (this has to be hooked up paying great care with equal lengths of pipes and heights of the tanks for it to work) but everyone assures me we won't run out of hot water.

If she has a gas heater, she may not have enough gas getting to it. Some older houses don't have the gas service required for a tankless heater.

Any thoughts? Pros? Cons?
Tankless, not even close ... The main pro, for me, is not having to deal with the awful water heater tank issues I've had in my past 2 homes & having to remove old ones & install new ones in each. Considering they were both located in the attic of each house, with attic door & ladder being in the hallway ceilings, one that was 12ft. high, and both with openings barely wide enough to get a tank through, installation was a BITCH, and God forbid they leak or completely rupture - frickin nightmare.
My new home has tankless, and it is so awesome. Pressure is great, water heats in just a few seconds (gas), & I'm completely worry & stress free about going through the awful crap I did with my previous 2 tanks. Honestly, I can't think of one reason why anyone building a home would not go with tankless.
I can't imagine traditional tanks will even be put in any new home construction within the next couple of years. They should be a thing of the past, imo, done away with for good. ... I hate them, especially in attics (dumbest idea since popcorn ceilings). ... Tankless all the way!!!

If it's gas just plug it into an extension cord, it doesn't draw many amps.

nola, i'm in the same scenario... planning/building soon, and we are going outdoor natural gas tankless.... makes too much sense not to...
trying to make this house as energy efficient as possible for a few reasons....

tankless costs twice as much to purchase. also, i case of breakage of unit, it loses as much water as a tank.
i was going tankless because our tank in attic "broke" but was told the house would have been flooded if it was a tankless also. to replace with another tank was 1400, tankless would have been 3200.

that's why i'm going outdoor... plus, no need to ventilate it if it's outdoor...

retrofitting a tankless is much more expensive... really not worth it, IMO...
but i'm building a new house... not retrofitting....

The farther away it is from the heater the longer it will take. And if it's an areated faucet it will take even longer. my kitchen faucet takes a couple minutes to get hot because it's only putting out maybe a gallon a minute because it's areated. I even have mine on a manifold or home run system where each line is ran to each fixture so it's less water being used. I really like mine I can run the shower and the tub at same time with no problem. I do worry about maintenance cause I've done none and eventually breaking. If you had two heaters on each side of the house you could fix the problem of it taking longer than conventional.
