Replacing a water heater ranges from moderately challenging to highly hazardous depending on your setup. For a standard electric tank, it is a manageable DIY job. For gas, tankless, or hybrid units, it is strictly recommended to hire a licensed professional due to the risks of gas leaks, venting hazards, and complex wiring.
Yes, you can replace a water heater yourself, provided you are handy and have moderate DIY experience. It takes about 3 to 4 hours and saves roughly $400 to $800 in labor. However, gas and tankless water heaters carry higher risks and are usually best left to professionals.
A: Traditional tank water heaters usually last 8–12 years, while tankless units often last 15–20+ years. Q: Should I replace my water heater if it's over 10 years old? A: Often yes. Even if it still works, the risk of leaks and sudden failure increases significantly after 10 years.
Here are some estimated labor cost price ranges for a water heater replacement: Tank-style water heater: $150 to $450. Tankless water heater: $600 to $1,900. Switching from tank-style to tankless: $150 to $2,500.
Can You Install a Water Heater Yourself? You can, but it's risky. The safety hazards, potential code violations and voided warranties outweigh any short-term savings.
Traditional tank water heaters last 8 to 12 years, while tankless models typically last 15 to 20 years. Lifespans vary greatly depending on water quality, unit design, and whether you perform regular maintenance like flushing the tank and checking the anode rod.
The Home Depot offers traditional water heater tanks and modern tankless units, both powered by either gas or electricity. Depending on your selection, the average cost for standard tank installation is generally between $1,600 to $2,400. Tankless installation can range from $2,400 to $5,400.
Tank to Tank Installation: On average, replacing a gas or electric water tank with a similar model takes two to three hours. It takes between 45 to 60 minutes to drain, disconnect and remove your old water heater.
Some of the most reliable tank water heater brands in 2026 include Rheem, A.O. Smith, and Bradford White. These manufacturers have long histories of producing durable, efficient heaters with strong warranty coverage. Rheem is known for overall dependability and wide availability, A.O.
Water leaks are perhaps the most common type of water heater issue you'll face. Any water heater will start to leak eventually, as by nature water will eventually corrode your tank and create microscopic cracks or fractures. However, this isn't always a sign that your tank is what's leaking.
A new 40-gallon water heater costs between $𝟒𝟎𝟎 and $𝟐,𝟎𝟎𝟎 for the unit alone, depending on the fuel type, brand, and efficiency. When factoring in professional installation, the total typically ranges from $𝟖𝟎𝟎 to $𝟑,𝟎𝟎𝟎.
This problem usually comes down to capacity, heat production, or mixing issues inside your plumbing system. Sometimes the fix is simple, like adjusting your water heater temperature or flushing out sediment. Other times you may need a new mixing valve, an element replacement, or a different size water heater.
If the project is as simple as replacing an old water heater with a new one, a handyman can likely do it with no trouble. However, converting a gas water heater to an electric one or putting in specific wiring and framing for the water heater will likely require the skill set of a licensed professional.
A water heater making popping, banging, or rumbling noises could be a sign that the unit is failing. If your hot water is yellow, discolored, or rusty, this is a sign that the anode rod in your water heater tank is beginning to fail. The anode rod is responsible for protecting the interior of the tank from corrosion.
We recommend going with Rheem, specifically for the Professional Series with 8 Year Warranty.
There isn't a single "number 1" model, as the ideal water heater depends on your home's setup, but top-rated brands dominating the market include Rheem (best overall tank/tankless) and A.O. Smith (best for durability and commercial-grade units).
Bradford White water heaters are widely regarded as some of the most durable on the market.

After installing a new water heater, expect a short waiting period before you have hot water, minor noises as the tank fills and heats, and potentially some air or discolored water pushing through your pipes initially.
Stores like Home Depot and Lowe's often include removal when delivering a replacement unit. This is the most convenient option, especially if the old unit is still in place and connected.
Heat pump water heaters move heat from one place to another instead of generating heat directly for providing hot water, resulting in high efficiencies and significant cost savings. Solar water heaters use the sun's heat to provide hot water and also save money on energy bills.
Naturally, tanks that heat more gallons of water typically have a higher price point, so the larger the tank size, the more you can expect to pay. For example, the average 40-gallon water heater installation cost runs between $1,000 and $2,500, while its 80-gallon counterpart runs between $2,650 and $3,910.
