    Just out of curiosity, what are the energy savings between a tank heater and a tankless? And the price between the two.

    Nice, clean install though.

    Idk any actual numbers but the theory is your only heating the water when you need it. Instead of keeping say 40 gallons hot 24/7.

    Comfort also comes into play. You really don't have to worry about running out of hot water.

    They can get up to 98% so they can definitely save some money. I'm far from an expert on them I only work on a few a year. Initial cost can be quite a bit higher. One of the complaints I've heard about them is it takes longer to get hot water especially farther away from the unit because the pipes stay cold and you need to run that water out first.

    Isn't it the same issue with a tank water heater?

    But with a tankless you have to also wait for the burner prepurge and light off. A tank gives warm water right away. This also sometimes gives a "cold water sandwich"

    Yeah 3/4 to a tee at the ceiling, around 6ft I think. From there it goes to hard black pipe. 3/4 is all those units require as long as you have 1 1/4 from the meter and its the 1st gas appliance. Oh and yes natural gas.

    A couple guys from work went to a class and the newest ones coming out will run on 1/2". It doesn't matter if its before or after other appliances as long as it gets 3.5" inlet.

    They can save on gas but if you factor in first cost, maintenance and repairs you
    don't have with a tank, is the net result savings? Not if you lose a $xxx board!

    That's not much different then high end hvac systems. 16 seer 2 stage, mod furnace, and a couple repairs and there go all your savings.

    Agreed, cheaper to repair a cheaper hot water tank, than spend more upfront on a nifty tankless loaded with features that will break at some point that costs $$$ to fix, and bam, all the savings you saved up, evaporate.
