    Hello!
    I get to pick out a new water heater! In looking at the various Rheem models, I see that there are some listed as "Ultra Low NOx", but I can't seem to find any information on what exactly that means? Do these water heaters have a cleaner combustion process?

    Any suggestions for a new water heater?
    Thanks!

    NOx is shorthand for nitrogen oxides, a component of air pollution. Some areas of the country restrict the amount of nitrogen oxides from all appliances using fossil fuel and these areas require low NOx or ultra low NOx certified burners.

    If you live in an area that requires low or ultra low NOx devices then you have no choice but to purchase and install the required appliance. Your local permitting office will have the details.

    Do they work well?

    Thanks for the explanation!

    Do they work well and should I consider it, even if it's not required? Are they any more energy efficient?

    Sorry, I don't know the answer to those questions. I know there are charts available on the Internet listing various manufacturers products and their government-assigned efficiency ratings but off hand I don't remember just where those charts are located.

    Whether or not you "should" buy a low NOx model even if not required is a matter for your own conscience.

    Ultra Low nox models, which by the way cost at least 50% more than regular, were mandated effective Jan 1, 2008, in the South Coast Air Quality (SCAQMD) management district of southern California ( LA, Orange, Riverside, and urban San Bernardino Counties.). They were mandated effective Jan. 1, 2009, in the Bay Area Air Quality Management District ( BAAQMD), San Francisco, Oakland, Alameda, Sonoma, and I think a few other Counties.

    In the affected areas, they are the only models stocked and legally available for sale. OUTSIDE the affected areas, you probably will not find them stocked. You could probably order one, but the cost is high.
  6. thats probably a very good brand

    if it is made by Bradford White it is probably a good brand...


    Unlike American-Whirlpool water heaters who use
    their customers like gueniee pigs to test out their products on .....


    Bradford White do all their test trials in their factory labs
    and are %100 % sure it is not going to be a problem once it is in the field..

    but if you dont need it where you live ,
    I would not buy it, cause parts might be a tad bit hard to get

    That statement is pretty deep. I had to re-read to fully grasp the context. To pollute or not pollute, that is the question...

    It is really not so deep. An ultra low nox unit will not be stocked anywhere that it is not mandated. POSSIBLY you could order one, but you could take cold showers too, and not use any gas. You can be the next Ed Begley. Write a book.

    Ultra-Low nox is only sold in Southern California. Outside of that area, and you probably don't need one. Just go with a BFG heater from Lowe's.

    If not the BFG, go with the upper model of the Energy Smart Gas (SG).
