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 Durham

How long do hot water heaters typically last?

Standard tank water heaters usually last between 10 to 15 years. Tankless water heaters, which heat water on demand, often have a longer lifespan, potentially 20 years or more with good maintenance. The conditions in your Durham home will affect how long your unit serves you well.

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 efficient type. They operate by heating water only when it's needed, which eliminates the standby energy losses associated with keeping a large tank of water hot constantly. This can lead to significant energy savings for Durham households.

What are signs I need a new water heater?

Signs you might need a new water heater in Durham include a lack of hot water, strange noises like popping or rumbling, visible rust or leaks from the unit, or a sudden increase in your energy bills. If your current heater is over a decade old, it's a good time to consider replacement.

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

For tank-style water heaters, sediment buildup is a very common issue that can decrease efficiency and cause noise. Other frequent problems include thermostat malfunctions or issues with the heating elements. Regular professional maintenance can help prevent many of these common problems in your Durham home.

Is it worth it to repair a hot water heater?

Repairing a water heater can be a good option if the problem is minor and the unit is still relatively young. However, if your water heater is old and requires a major repair, investing in a new, more efficient model might be more cost-effective in the long run for your Durham residence. A professional can help you decide.
