Purchasing a water heater directly from a plumber is often the best choice. While you will pay more upfront, it guarantees a higher-quality "pro-grade" unit, ensures you get the correct model, and provides seamless, end-to-end warranty and installation support if something goes wrong.
The Home Depot strongly recommends that you use an experienced, licensed plumber to install your new water heater, because they will know the required codes to complete a safe and compliant installation.
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.
Installing a 40-gallon gas water heater from Lowe's typically costs $1,100 to $2,000 total, including the unit, labor, and materials. The physical heater costs between $450 and $800, while professional labor, permits, and connecting pipes add another $650 to $1,200.
The "best" water heater depends on your preferred fuel type and whether you want a traditional tank or a tankless system. Master plumbers and consumer experts consistently rank Rheem, A. O. Smith, and Bradford White as top overall brands.
A 40-gallon tank water heater installation costs $700 to $2,300, with an average cost of $1,650. Prices vary based on energy source and installation complexity. The national average cost to install a 40-gallon tank water heater ranges from $700 to $2,300.
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.
In some cases, if your water heater leaks or doesn't heat up, you may be able to repair the existing unit. But it's helpful to start by determining the expected life of the appliance. The average life expectancy of a water heater is about 8 to 12 years.
Professional labor costs for installation make up over half of the total cost of a new water heater. In general, tankless water heaters are more expensive to install than storage tank models, particularly if you're replacing a tank model with a tankless one because of the additional labor needed.
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.
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.
Here are the top geyser brands in India (2025) based on performance, safety, and durability:
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.
Replacing a 55-gallon water heater costs between $1,500 and $3,500 on average, including both the new unit and professional installation. The exact price depends primarily on your fuel type, building code upgrades, and permit requirements.
Excessive Water Pressure: High pressure stresses your system and shortens its lifespan. A pressure-reducing valve can help. Undersized System: A unit that's too small for your household's demand works harder and wears out faster. Proper sizing during installation is critical.
When searching for the most reliable water heater, professional plumbers consistently recommend A.O. Smith, Bradford White, and Rheem. For long-term tank durability and a "set-it-and-forget-it" experience, A.O. Smith and Bradford White are top choices. If you prioritize high-tech smart features and energy efficiency, Rheem is a market leader.
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.
The "7-minute rule" at Home Depot refers to the attendance grace period, which dictates that you can clock in up to 7 minutes after your scheduled start time without being marked tardy. If you clock in at the 8-minute mark or later, you will receive an attendance occurrence (or half-point penalty).
Tankless water heaters are the longest-lasting, averaging 20+ years, while the Rheem Marathon leads tank-style heaters with a lifetime warranty. Standard steel-tank models fail within 8–12 years, so maximizing longevity requires either choosing a premium model, a tankless unit, or maintaining standard units.
Water heaters combine electricity or natural gas with pressurized water—three elements that can be extremely dangerous if not handled correctly. An unsafe installation can result in: Gas leaks that could cause carbon monoxide poisoning or explosions. Electrical hazards leading to shocks or fire.
The most energy-efficient water heaters are Heat Pump (Hybrid) water heaters, which use electricity to move ambient heat into the water rather than generating it from scratch. For highest overall efficiency and sustainability, Solar water heaters are the ultimate leader, though they are highly climate-dependent and require a conventional backup.
Yes, Costco sells water heaters, including traditional tank and tankless models (mostly from the brand Rheem). Rather than picking one up off the shelf, you purchase the unit and schedule a home consultation through their affiliated local contractors.
