What affects the price

When you are looking at the price of a new water heater, a few main things shift the final number. The type of unit you choose—whether it is a tank model or a tankless system—is the biggest factor. You also have to consider the fuel source, like gas or electric, and the physical space where the heater sits. If your home needs new venting, updated piping, or a different hookup to meet current safety codes, that adds labor time to the project.

About this service

This total price includes the physical unit plus the labor needed to get it running. Factors such as whether you are transitioning from a traditional tank to a tankless model or upgrading an existing unit will shift the final number. We evaluate your specific space to ensure the system is sized correctly for your household needs. Exact pricing confirmed free on the call.

Even though it is warm outside, your water heater is still working daily. Summer is a great time to adjust your settings, as the incoming water isn't as cold, which can actually help extend the life of your unit. If you are planning a home renovation or just want to upgrade to a more efficient model, call us to talk through your options.

Frequently asked in Raleigh

How long do hot water heaters typically last?

Traditional tank water heaters generally last between 8 and 12 years. Tankless water heaters, with proper maintenance, can often last 20 years or more. The climate in Raleigh and how frequently the unit is used will influence its lifespan. Regular professional servicing can help.

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 the most energy-efficient option. They only heat water when you need it, eliminating the standby heat loss associated with keeping a large tank of water hot. This can lead to noticeable savings on your utility bills in Raleigh. They also save space.

What are signs I need a new water heater?

Look for signs like rusty or discolored hot water, unusual noises such as banging or rumbling, or visible leaks around the unit. If your hot water supply is inconsistent or you're frequently running out of hot water, it's a strong indicator. An aging unit nearing the end of its typical lifespan also warrants attention.

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

Sediment buildup is a frequent issue that can reduce efficiency and shorten the lifespan of water heaters, especially in areas with hard water. Other common problems include thermostat malfunctions, heating element failures, or pilot light issues in gas units. For tankless models, scale buildup can also be a concern if not properly maintained.

Is it worth it to repair a water heater?

Repairing a water heater can be a good option for newer units with minor issues. However, if the unit is old and requires extensive repairs, investing in a new, more efficient model might be more cost-effective in the long run. A licensed pro can assess the situation and advise you.
