    Hello,

    My water heater is now 10 years old and it is time to replace it before it floods out the basement.

    I have been thinking of a tank-less like a Rinnai, but I am not sure how many gallons per minute I need. These are also expensive, so I would also like to know if there are other brands of good quality that might cost less.

    If I go with a traditional water heater with a tank, can someone recommend a quality brand that is a good value?

    Can you go with a gas tankless? I would not consider an electric tankless. How hard is your water? If you have really hard water your tankless would require an annual descaling, but it isn't terribly hard to do from what I've heard from friends that have them. New tank type water heaters have gotten bigger to satisfy additional insulation requirements by the federal government. This can cause issues when they are located in a small utility closet. The tankless water heaters are supposed to have a longer life than tanks so it may be a wash on cost. As to gallons per minute, how many people shower at the same time in your house? If only one, a standard home unit should provide plenty of uninterrupted hot water. You may not want to run a load of hot laundry wash and the dishwasher just before you hop into the shower though. Low flow shower heads don't use that many gpm.

    I replaced my ancient gas water heater last week with a A.O. Smith 40 gallon traditional tank that cost about $450 at Home Depot. Plumber install was $600. I didn’t feel like spending the money for a tankless. The new tanks appear to be made better than older ones.

    Unless it doesn’t matter, you should calculate how long it will take to break even on a tankless heater. I love helping the planet, but if if it cost three times (for example) what I’d pay using a regular water heater, I’ll skip it.
