It depends on what brand you buy and if it will be gas or electric.
My husband LOVES them and swears by them. We had one in our other house and let me tell you I could take a 2 hour shower if I wanted to. The most important thing is to get the correct size tankless heater for your home. you may even want to install more than one depending on whether or not you have more than one floor.If I get more info I'll add to this post later. Ok hubby walked just got home and said this....The gas ones are better. The brand that he reccomends is Rinnai ( www.foreverhotwater.com)and the electric one that he likes is called EEMax. He said it will pay for itself within 2yrs with more economical gas and electric bills.If it's sized correctly it should be hot enough for a HOT bath. Rinnai comes with a remote and you can set the temperature higher than 120 degrees for a super hot bath.Have fun,you'll love it.As for one of the other posters saying that it takes her friends tankless a while to get going in the morning my husband said that Rinnai commisioned a pump company to make a recirculating pump thats compatabile with their heaters. It will create hot water within 15 seconds( if installed far away and as little as a second or two if it's installed close.The website for that is www.gothotwater.com.It's the only pump approved for use with Rinnai heaters.

I believe they are also rated in gallons per minute at a certain temperature. So if it's rated for 3 gallons a minute at 120 and two showers at the same time is using 2 gallons a minute, then you can shower indefinately without running out of hot water. I hear there can be problems/isuues when installed with a well water system do to a non constant input flow of water. But there are ways to normalize the input flow rate from a well system.

I don't have one, but my friend does, and she loves hers. She says you can run the hot water in every sink or shower in the house at the same time without running out. The only drawback she says is that it taks a minute or two initially (like first thing in the morning) for the water to run hot, but after that it stays hot all day. She's had hers awhile, so maybe the newer ones don't have any wait time now. I'm planning to convert mine later on this year when we remodel.

I sell, install, and service both standard gas water heaters as well as on demand gas units. Here are some points for you to ponder.
The initial investment of the on demand unit is higher. Depending on the hot water demands of the household the payback on the initial investment can vary but usually warrants the investment.
First and foremost, the on demand unit is efficient, it’s not heating water in and tank and maintaining that water at a particular temperature. Rather it heats water as it is being used. So, over time it’s using less gas to heat the water being used.
The only con of the unit is if, and when a repair is needed on demand units, because of the compact design are somewhat difficult to work on. Even experienced service technicians find them time consuming to work on. The result is higher labor charges incurred for repairs. Also parts are not always on hand because of the nature of the units, so you may end up with extended down time if parts are on order.
Some suggestions would be, buy locally from a dealer that sells as well as services the unit. They will walk you through sizing the unit for your home and hot water requirements. I just have two brands that I, as well as my Tech’s are comfortable working on. We like the design and the backing in the parts dept. from the manufacturer. I stock parts for both brands and handle most repairs same day with very little down time for my customer.
On demand units are becoming more popular and more brands are making their way to the market, I’m not going to knock any particular brand, but I will say do your homework and research the unit you are interested in.
Again local service is a big plus, as I said I personally have two brands that I work with, and I will not service any other brand as of right now, not to say I won’t add other brands in the future. My last point is, do not even bother looking at an electric unit unless it is not going to service the whole house, and rather serve as a one sink water heater. Any other use of an electric on demand unit is inefficient.

You will have plenty of very hot water. I had a problem with one of my tankless water heaters, the copper coils were soldered to steel tubing. In two years galvanic action deteriorated the metal and the unit failed. Be sure to check that there is only one type of steel tubing inside the tank.

Installed one in Jan '06. we love it. it is so nice to be able to take consecutive showers, or run multiple loads of wash, without waiting for the tank to reheat.
How hot is hot? our thermostat is set at 125. How big is your bathtub? there are limits. you may need a reservoir if you have a large tub. Talk to a plumber.
The only negative I see, is the initial cost. Ours required an upgraded venting system, a heat source to keep incoming pipes from freezing, (it is located in an unheated garage, in freezing MI) and larger gas lines from the meter to feed it.
Oh yes, wait time is a negative, the unit has to "kick on" then heat the water, then get it to the faucet, so like 30-40 seconds.

i do no longer imagine they have stuck on o.k.. no longer particular why. We merely equipped a clean abode (in Indiana) and neither the architect nor the custom abode builder cautioned them. With all of your desires for warm water, you may choose a number of tankless instruments, so I guess it will be heavily better extreme priced than one large elec water heater. if you're fearful about how briskly warm water arrives at a given area, you could positioned a lifelike go back pump for those places that are further remote from the water heater. those are user-friendly, all it does is save warm water circulating from the tank to the tap and lower back so there is continuously warm water on the tap. merely curious - why do not you want organic gas? it truly is a lot a lot less extreme priced than elec. If for safe practices causes, gas is merely as secure as elec.

From what I understand they serve plenty of hot water and save on electric. They are more expensive and if you live in an area that is proned to power outages and you are on city water a tank will give you 1 last shower.
