Interesting.

Just had a discussion with my heat and air guy about these. About a year ago, he put one in his house. I was thinking about it and replaced my water heater instead.

He told me this week that I made the better decision.

Yes, they don't run out of water. When they are running. I don't mean that they mechanically don't run, but when the power goes out a gas water heater still gives you hot water. A tankless water heater used electrical circuits to run.

Electric versions work, but (especially with kids) people get in the shower and stay there. All the while, that little wheel is just spinning around on the electic meter fast enough to act as a buzz saw. Even in the gas versions (which he has) the water usage goes up and so does the gas bill.

Not saying they aren't good, but these are things to consider.

the company he works for now, and worked for a few years ago, no longer will install the electric ones due to the power consumption and the complaints that they got from unhappy customers complaining about their increased electricity bills.

Haha. My buddy says that the only reason his wife knows to get out of the shower is when the water gets cold.

my dad has installed a few, but not any in the last year or so that i have herd of. he said he really likes them, and the one lady i remember him installing a natural gas paloma brand tankless for says she absolutely loves it. hers was the first one he ever installed, this was several years back, but i remember her calling last year i think it was, she said she still loves it but was concerned about something she herd and did some research on, she wanted to order some spare parts, because something about the new models required a power outlet and or had no pilot or something, the just of it was that if the power was ever out (after she ever had to replace some part), she basically would not have hot water despite it being a natural gas unit, because the new parts/units would require outlet power to spark light the heater. so, that may be something to consider on the unit you select.
from what i understand it never runs out of hot water, and it gets it just as hot, but if you are used to a circulating pump on your hot water system, you will not have quite as fast a response to getting hot water to the taps. naturally because it has to heat the water, then the water has to be pushed through the system to the tap, vs the water already being hot in the tank and having been circulating through the system by the pump.
i also remember he has to do extra work making a vent hole from the heater to the exterior of the house, because the unit used a dual core pipe vent, so it would burn air from outside the house, and vent the burned fumes out the same pipe. however this may not apply to some units or circumstances. my father would be a better guy to talk to than me about this.

but they make sense to me, why pay to constantly keep water heated to the desired temperature all day, when you really only need it for a fraction of the time that you are paying to keep it that temperature.

not a shout out for business or anything, but if you have any questions and want to talk to the plumber (my father) you can call the business phone and ask, he may have to check his records and reports to remember what it cost and any particulars on the models or what have you, but i can assure you he is the most honest man i have ever known and he can tell you what he knows and what he would suggest or recommend, and i am sure after doing some research on the parts and units, and looking at the home, he could give you a bid on the job as well. if you call, my mother is in charge of the phone and scheduling, but if he is not around the house/office she can either get you in touch with him, or have him give you a call when hes not busy.

We love our gas one. Costs more. Does save on electricity, but that's not why we got it. It is absolutely awesome to be able to take baths one right after the other and not worry about running out of hot water. And also have the dishwasher and clothes washer running all at the same time. That really helps as we both have more than full time jobs so we can't space those chores out.

I have had a Bosch 125 Aquastar in use for over 15 years now. It runs on NG and uses two D-Cell batteries for the ignition. During the power outage, 2 years ago, we always had hot water. A friend and myself installed it .... You just have to get used to the slight delay before the hot water makes it to the faucet. We are going to be upgrading to a little larger model when this one dies. BTW, Bosch has excellent Customer Service too ..... I can highly recommend it. :)

We have a Rinnai as well, we love it. Had it installed by Owasso Service Company, they are a really good company to work with. This is the second house we've had one installed in and they are very professional and prompt. They are a family company run by two brothers and the brothers do all the installation, servicing, etc. I was talking to one of the owners about options on a tankless when he came out to give me a quote on installing one for us in this house, he told me there are some different brands on the market nowadays that perform a little better than the Rinnai and they install them too but he said that the reason he recommends the Rinnai is he's never had to come back and work on a single one of them in the 8 years or so he's been installing them.

How does a gas hot water tank work during an power outage, my gas water tank has a electric igniter in it that fire the burner off. No electricity no power to igniter or the valve that has to open in order to allow gas thru to feed the burner.

newer gas ones dont work during an outage either, you only have hot water as long as the water in the tank stays insulated and hot. Once it cools the tank is cold until power comes back on and allows the tank to heat up again.

Pilot light and mechanical gas valve/thermostat....no electricity required.
