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

When calculating the cost of a tankless water heater and the labor to install it, we consider the unit's flow rate and your home’s existing utility connections. Upgrading to this technology usually requires specific venting and plumbing modifications that impact the total price. We ensure the system is properly sized for your family’s water usage. 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 usually last between 10 to 15 years. Tankless water heaters, while more expensive to install upfront, are designed for greater longevity, often lasting 20 years or more with proper maintenance. This extended lifespan can offer long-term value.

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. They heat water only when it's needed, eliminating the standby energy losses associated with keeping a large tank of water hot constantly. This on-demand heating can lead to lower energy bills.

What are signs I need a new water heater?

Look for indicators like leaks around the unit, unusual noises such as rumbling or popping, discolored or rusty water, or a consistent lack of hot water. If your current heater is approaching its expected lifespan, it's a good time to start considering a replacement.

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

Sediment buildup within the tank is a frequent issue that can reduce efficiency and shorten the unit's lifespan. Other common problems include thermostat malfunctions, issues with heating elements, or leaks from the tank. Regular maintenance is key to preventing these.

Is it worth it to repair a water heater?

Repairing a water heater is often a good option for newer units with straightforward issues, like a faulty thermostat or a minor leak. However, for older units experiencing significant problems or frequent repairs, investing in a new, more efficient model is usually the more economical long-term decision.
