Is tankless worth it?

If you plan to stay 10+ years, yes. It costs two to three times more to install but lasts twice as long and cuts water heating energy 20% to 30%.

How long does a water heater last?

Eight to twelve years for a gas tank, ten to fifteen for electric, and twenty or more for tankless with annual descaling.

What size water heater do I need?

40 gallons for two to three people, 50 for three to four, 75 to 80 for five or more. First-hour rating matters more than raw capacity.

Is a heat pump water heater a good idea?

In a garage or basement with adequate space and a mild climate, it cuts water heating cost 60% to 70% and often qualifies for large rebates.

Most jurisdictions require one, especially for gas and venting changes. Unpermitted work can surface at resale.
