  • 250SX - Should be better

    Jul 04 '07
    Pros: Saves $$$ over a tank. Mine is quiet. It saves space if inside.
    Cons: Plumber charges to install a 3/4" gas line.

    Summary: My experience is similar to kopperheds. I exhaust vented the 250SX straight up through the roof with all the stainless steel components. But blowing rain will get into the piping and drop straight down filling up the gas valve ruining it. If you

    Pros: Energy efficient?
    Cons: Not recommended for well water - bad investment.

    Pros: Endless hot water at a minimal cost
    Cons: lag times and educating others that it doesn't work the same as other water heaters.

    Summary: I like this unit quite a bit. Yes, it involved a bit of new learning curve to install it but once it was in (for the last 7 months) has worked perfectly. It works sufficiently even though we were forced to hook it up to a 1/2" natural gas line rather

    Pros: When it works it's great.
    Cons: This particular model is a lemon.

    Pros: When it works it is great.
    Cons: Be prepared for many hours of problems.

    Summary: I recently purchased a 250sx tankless hot water heater. It promised hot water. I purchased it for the savings, environmentally friendly, and all the other hype. I have had nothing but problems. I have almost always been blamed for it being installed

    Pros: Always have hot water. Saves $$$ on the long hall.
    Cons: Sticker Shock. One max water temp available at a time. Remotes only store one temperature.

    Summary: Installed in my home in Florida with ground water of 58F temp. After some re-education the family and I love it. We each have our setting and you know when you step in to the shower or bath that the water is the temp. you want. Also bought two remotes

    Pros: The unit performed flawlessly and exactly as advertised (endless hot water, no fluctuation, etc)
    Cons: Won't activate with low flow rate.

    Summary: We installed the 250SX 5 months ago. Worked flawlessly. Good water flow, endless hot water on demand. No problems with simultaneous dish washer / faucets / shower demands. Over the weekend it shut-down, gave an error code. Was unable to reset &
