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

The cost to install a tankless system accounts for the unit, pipe rerouting, and potential electrical upgrades. If your home needs a larger gas line to support the unit’s power, the labor price will rise. We assess your home’s current plumbing and energy capacity before starting any work.

Frequently asked in Raleigh

How long do hot water heaters typically last?

Traditional tank water heaters typically last between 10 to 15 years. Tankless water heaters, known for their efficiency, can often provide hot water for 20 years or more. Factors like water quality and usage patterns in Raleigh can influence the actual lifespan of your unit.

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

What is the most efficient type of water heater?

Tankless water heaters are generally considered the most energy-efficient option available. They heat water on demand, eliminating the standby energy losses associated with keeping a large tank of water hot constantly. This can lead to significant savings on your energy bills in Raleigh.

What are signs I need a new water heater?

Signs that you need a new water heater include a decrease in hot water supply, rusty or discolored water, or unusual noises like popping or hissing.

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

Sediment buildup in traditional tanks is a frequent issue that can reduce efficiency and cause noise. Another common problem is a malfunctioning heating element or thermostat, leading to no hot water or inconsistent temperatures. Leaks from the tank itself are also a significant concern that needs prompt attention.

Is it worth it to repair a hot water heater?

The decision to repair depends on the specific problem and the age of your water heater. For younger units, minor repairs like replacing a valve might be cost-effective. However, if the tank is leaking or showing signs of corrosion, or if the unit is nearing the end of its lifespan, a replacement is often the more economical choice for your Raleigh home.
