    Recirculating pumps are awesome for long runs but they are best if you insulate the hot line going to the far spigot. There are basically two ways to do it. One is have a pump on your HWH and have sensor valves attached to the farthest sink.

    This way if you have multiple bathrooms a long ways from the HWH you can put a sensor valve in each room. The other is to have one under the kitchen sink (or any sink that has an outlet next to it) that is a pump and sensor all in one like this.

    With the ladder the pump only runs when the temp drops and it's recirculating and you can program it to only run at certain times. The previous version is probably best for large homes with multiple bathrooms with long runs.

    They're mostly all crap nowadays. Just get a cheap Menard's one and maintain it cause I doubt there's anything better. Total crap shoot on those.

    One thing I noticed when I bought a new water heater last year is there are models with a 5 or 7 year warranty and models with up to a 12 year warranty. The main difference I noticed was the models with a longer warranty have two sacrificial anode rods in them instead of one. Apart from that they looked about the same.

    When i bought my last water heater I purchased from a plumbing supply house.

    The biggest difference is everything seemed to be just slightly nicer. The drain at the bottom was brass versus plastic, longer warranty, just little things here and there that showed higher quality.

    Has performed well so far 3 years in. I drain it once a year and flush it as well

    I had my 5 year one for 23 years. I flushed it annually. Not once did it ever failed me. Only replaced it because I wanted an on demand system.

    Longer warranty= better bigger (usually) burner, two anodes, brass drain and usually better insulation.
    You can get more years out of one by changing the anodes every few yrs depending on water type. Eventually if you have a gas one the burner is going to burn through the bottom. I've never had an electric one so I can't speak to those I don't think I will ever have one.

    Knock on wood first.......I'm at 12 years here now on mine which is by far the most I've ever gotten. I've also never flushed this tank and there's no doubt in my mind that flushing was shortening my tank's life by 2/3s.

    My 12 yr Rheem Performance Platinum only has one anode unfortunately. Also has a plastic drain valve but I plan on flushing it once a year and I'll swap the brass one that I removed from the old Rheem, which lasted 20 yrs with only one flushing that I know of and no anode replacement. Very hard water here too. The plumber friend up the street I talked to said he was of the belief that the tanks were the same regardless of warranty. I made sure I installed it with the proper dielectric unions and a catch basin underneath so that any future seepage leaks can be directed by hose to the sump pump until replacement. I had to order a short one which not all places have in stock, because of the low plumbing above that I didn't want to have to redo. Also, installed a 2 gal expansion tank which I didn't have which may help with longevity (hoping).

    I have never flushed my HWH, nor have I pulled the anode, lived here for 22 years, and have replaced the HWH one time, its a Rheem, this one is 8 years old from HD. I would never replace parts on a HWH, I would just replace the unit..

    Same here. At least for a gas water heater. I just replace the whole unit every ten years or so and check for water in the pan once in a while. Other than that the only time I touch the heater is to turn it down low when I travel and then shut off the water in the house.
