Every year around the first cold snap, we get a wave of calls and questions about water heater installation and repair. To make things easier, we’ve pulled together answers to the questions we hear most.
Can I install a water heater myself?
Technically, yes — if you have the right equipment, knowledge of local code, and any required licenses for gas or electrical work. In practice, it’s rarely safe or cost-effective for most homeowners. Small mistakes with gas lines, venting, or electrical connections can create real safety risks.
Do I need a plumber to replace my water heater?
Many homeowners have a trusted handyman, and that’s fine for a lot of home projects. But we recommend a licensed plumber specifically for water heater work — see our thoughts on hiring a handyman for plumbing versus a licensed pro. Gas lines, venting, and code compliance require specialized expertise, and licensing and warranties matter if something goes wrong later.
How much does it cost to install a water heater?
Pricing depends on the unit and installation complexity. As a general guide, conventional tank water heater installation typically starts around $1,395, and tankless installation starts around $1,800. Check our estimate ranges for current pricing, or call for a free quote specific to your home.
How do I maintain or extend the life of my water heater?
For tank water heaters, a yearly flush and inspection goes a long way. For tankless units, an annual flush and cleaning of the isolation valves keeps efficiency up. Electric water heaters typically need their anode rod replaced every 2-5 years — see our anode rod guide for details — and gas water heaters should have their burner checked annually.
How long should a water heater last?
Traditional tank water heaters generally last 6-10 years. Tankless units tend to last significantly longer, often 12-20 years, thanks to less wear from constant heating and reheating of stored water. If yours is getting up there in age, our guide on signs you need to replace your water heater can help you decide whether to repair or replace.
Does the brand matter?
Yes. We consistently recommend Bradford White for tank water heaters and Noritz or Rinnai for tankless units, based on years of installs and callbacks. Bradford White units are made in the USA with a standard 6-year warranty and a strong reputation for durability. Noritz and Rinnai tankless units typically carry a 12-year warranty and are known for precision manufacturing and long service life.
Tankless vs. conventional: what’s the real difference?
Tankless water heaters heat water on demand as you use it, rather than storing and continuously reheating a tank of water. For most homes, that means better energy efficiency, a longer lifespan, and effectively unlimited hot water — no waiting for a tank to refill and reheat after a long shower. See our full comparison in tank vs. tankless water heaters.
