What affects the price

Replacing a water heater involves several variables that change the final bill. The main factors are the type of unit you choose—like standard tank models versus tankless systems—and the fuel source, whether gas or electric. Installation complexity also plays a role, especially if we need to update venting, gas lines, or electrical wiring to meet current building codes. Relocating a unit or upgrading to a higher capacity will also shift the bottom line.

About this service

Installing a tankless unit is more involved than replacing a standard tank because it requires precise gas and exhaust adjustments. The final cost depends on the model's efficiency rating and the work required to bring your home up to code for the new unit. We review your home’s specific layout to determine the final amount. Exact pricing confirmed free on the call.

Frequently asked in Memphis

How long do hot water heaters typically last?

In Memphis, tank water heaters usually last between 8 to 12 years. Tankless water heaters can offer a longer lifespan, potentially up to 20 years, especially with consistent maintenance. The hard water common in some areas can affect unit longevity.

What is the average cost of putting in a water heater?

What is the most efficient type of water heater?

For energy efficiency in Memphis homes, tankless water heaters are generally the most efficient. They heat water only when needed, reducing the energy wasted by traditional tanks that continuously reheat stored water. This can lead to lower utility bills.

What are signs I need a new water heater?

Signs that you need a new water heater include rusty or discolored hot water, a lack of hot water, or leaks from the tank. Unusual noises or a noticeable increase in your energy bills are also strong indicators that it's time for a replacement.

What is the most common problem with a hot water heater?

Sediment buildup is a common issue in tank water heaters, which can reduce efficiency and cause noise. Another frequent problem involves a faulty heating element or thermostat. These are often fixable by a qualified professional.

Is it worth it to repair a hot water heater?

Repairing a water heater is often a sensible choice for minor issues on a relatively new unit. However, if your Memphis water heater is old and requires extensive repairs, investing in a new, more energy-efficient model might be more cost-effective in the long run.
