    Cool. You'll love it! - Endless hot water!

    Our gas bill has been 30%-40% lower each month since I installed ours last year.

    Default location....

    Just a note to others who may be interested, note that the temperature of the incoming water (AZ) is critical to the gpm that he units can produce. Up north these are still useful but unlikely to service the entire house in the winter.

    Yes John and I do mention that in my writeup...that it favors gas fired and Southern states. That said they are used the world over except in the US, parts of Australia and Canada.

    But I must agree with you IMO.

    Yes and I have gotten several comments from others up north like Mi and Wisconsin that have said the same exact thing....so I guess it works there too.

    Default in hot water...

    I am curious how well it does because I build houses in the Chicago area.

    It seems relative to your use and gpm requirements.

    I am very sure it works great for maybe one large bath and the kitchen or some other combination, but if you get into large baths with multiple shower heads, Jacuzzis and sevaral other baths etc... it all gets back to the gpm.

    Large units are are rated like 7 gpm at 45 degree rise, say from 60 to 105. If the incoming water is 40 in the winter you need a 90 degeree rise and the gpm falls to maybe the low 5's. I have done many baths that one shower head and a few body sprays and your at 10 gpm. not very green for sure, but you get the picture.

    Another consideration is the gas service. If you have adequate gas delivery, you stay at the specs. If you have a marginal supply and/or pressure, the performance starts to deteriorate. Example I saw the other day; plenty of hot water as long as the boiler was not firing at the same time.

    I have seen other builders use multiple units to overcome gpm limitations. This has its own issues with multiple flues, water piping from more than one location and more involved gas piping and gas service sizing...

    I think they are really coming along and are a great appliance for the right installation; definetely the trend for the future. I just wanted to make sure if someone decided to go for it, the would take the time to run the numbers.

    Let me know what kind of performance you are actually experiencing in those colder climates relative to the usage.

    Thanks,

    John

    Actually, even a tempering tank makes a big difference as much of the time it can be full of water warming to room temperature. Solar can be great too, but more equipment and plumbing to deal with.

    The limitation with these tempering system is that it likely works 80 percent of the time, but that does not satisfy most people when it happens that they use all the tempered water and suddenly they are in a cold shower.
