What moves the number
- Tank or tankless. Tankless costs more up front but lasts longer and uses less energy.
- Gas or electric. Switching from one to the other can mean new gas lines or electrical work.
- Size. Bigger households need more hot water, so a bigger tank or a stronger tankless unit.
- Permits and code updates. Many towns require a permit. Older homes may need upgrades to meet code.
- Removing the old one. Hauling away the old tank is sometimes extra.
Tank or tankless?
- Tank: costs less up front and works for most homes. It keeps a tank of water hot all day, which uses more energy.
- Tankless: heats water only when you need it. It costs more up front, but it can last 20 years or more and costs less to run. A big household may need a larger unit, or more than one.
Signs it's time to replace
- Your tank is 8 to 12 years old or older. Gas tanks often wear out sooner than electric ones.
- Rusty water or water pooling around the base.
- Not enough hot water anymore.
- Popping or rumbling sounds from built-up sediment.
What to ask before you choose
- "Does the price include the permit, haul-away and any code upgrades?"
- "Is this the right size for my household?"
- "What's the warranty on the unit and on your work?"
- "Are there rebates from my utility company?" Many offer them for efficient models.
- "Are you licensed?" Most states license plumbers. Ask for the number.
The catch: a gas water heater that's installed wrong can leak carbon monoxide, a gas you can't see or smell. Don't DIY gas work. Hire a licensed pro, and keep a CO alarm in your home.
