Frequently Asked Questions
How long does a water heater last?
Tank water heaters last 8 to 12 years. Tankless models last 15 to 20 years. Annual flushing and maintenance extends the lifespan of both types.
Is a tankless water heater worth it?
Tankless heaters cost more upfront but save $100+ per year on energy and last nearly twice as long. They are worth it if you plan to stay in your home 5+ years.
How long does water heater installation take?
A standard tank replacement takes 2 to 4 hours. Switching from tank to tankless takes 4 to 8 hours due to gas line and venting modifications.
Are there rebates for energy-efficient water heaters?
Yes. Federal tax credits up to $2,000 are available for qualifying heat pump water heaters. Many utilities offer additional rebates of $200 to $500.
How do I know if my water heater needs replacing?
Replace if it is 10+ years old, leaking from the tank, producing rusty water, making unusual noises, or not heating water efficiently.
