Standard for new construction around here. I like mine. My neighbors like theirs. Haven't had any problems in the 5 years I've had it. Flush exchanger with vinegar once a year.

We had one installed when we built our home back in 2006. Rennai (sp?). We like it, but with a couple caveats:

1) check your max distance to the heater. Ours is a bit far away so it takes it a minute to heat up to shower temps.

2) depending on your size home, you might want to get 2 to begin with. We did not, and I regret it. Our 2 story home uses just one, and while nobody EVER has run out of hot water (even with several showers going), the wait to warm up the water is longest for our master bath (furthest bathroom from the unit). This was due to my budget constraints and overruns at the time of construction.

I guess that both points are kinda the same thing now that I read it...

I have two Noritz units, one on each side of the house, that was installed on a new construction. The delay in hot water delivery is minimal. I do have pretty hard municipal water so I flush my units twice a year which I perform myself—pretty simple even I can do it. I love everything about it and don’t miss traditional water heater tanks one bit.

We have a Rinnai in the house that we bought almost two years ago. It was serviced today. Technician said the squirrel cage fan was full of bugs that were sucked in through 5he intake side of the exhaust pipe. Very common according to him. We like the Rinnai, and it is the first tankless we have had. Sen a lot of electric ones installed in hospitals to solve hot water issues at the end of extended runs. We would do a tankless again.

Regarding the long warm up times, you can get a recirculating pump. Many of the new, larger, houses have them installed here but you can retrofit it. You hit a button (one installed by in the kitchen and one installed in the master bath) and it recirculates the water for a short period of time to "pre-heat" the water in the lines.

Basically, you hit the switch on your way to the toilet, and by the time you are ready to brush your teeth or turn on the shower, the line is already warm.

Edit: Some water heaters have the recirculation pump built in.

I want to thank Mr. Steed for starting this thread topic! I plan on building a new home within (hopefully) the next 2-3 years and this has given me some GREAT ideas on what to do in terms of installing a tankless system during the build. Great group of folks we've got here...tanks everyone!!! Big Grin

I've considered, but am hesitant to change. Been in our house for 8 years now, with a 50gal NG heater, gas bills about $25/mo in the summer (water heater and gas cooktop use during that time). Water costs here are rediculous, in that our sewer charges are twice what our water is, about $300 per month. Already, our kitchen sink has seems to be the longest to get hot water, about a minute - extending that time (and wasting significant amounts of water) would seem counter productive to simply replacing with another reasonably efficient tank water heater. Retrofitting a loop to allow hot water circulation to the taps would probably be cost prohibitive as well, but I'd love to hear about others following this option.

You might be able to install a small tankless under the kitchen sink that would give you hot water at the kitchen sink in seconds. I'd investigate that route given your situation. A lot of restaurants use them in their customer restrooms.
