What affects the price

The final price for a new water heater depends on a few moving parts. First, you have to choose the right fuel source—gas or electric—and decide if you want to stick with a standard tank or upgrade to a tankless model. We also look at the physical space where it sits and whether your current venting or gas lines meet modern safety codes. If we need to move the unit or upgrade plumbing to get it up to speed, that shifts the labor involved. Exact pricing confirmed free on the call.

About this service

When you bundle the unit and labor, you are paying for both the high-efficiency equipment and the expertise required to configure it. Factors influencing the total include the unit's capacity, existing plumbing condition, and any necessary modifications to your ventilation systems. These projects are more complex than traditional tank installs, so professional setup is essential for performance.

While you might not think about hot water as much in the summer, it is a great time to evaluate your system’s health. Because the incoming groundwater is warmer, your heater doesn't have to work as hard, making it a stress-free window to replace an aging unit before you hit the busy autumn season.

Frequently asked in Anaheim

How long do hot water heaters typically last?

Most traditional tank water heaters are designed to last between 10 to 15 years. Tankless water heaters often have a longer lifespan, potentially reaching 20 years or more with good upkeep. The age of your current unit is a significant factor when deciding on repair versus replacement.

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

What is the most efficient type of water heater?

Tankless water heaters are typically the most energy-efficient option available. They heat water on demand, meaning they only consume energy when hot water is actually being used, unlike tank models which constantly maintain a temperature. This can lead to significant savings on energy bills over time.

What are signs I need a new water heater?

You should consider a new water heater if you notice rusty water, unusual noises like banging or popping, frequent leaks around the unit, or a significant decrease in hot water availability. If your current heater is over a decade old and exhibiting these issues, it's a strong indicator that replacement is needed.

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

Sediment buildup inside the tank is a prevalent issue for conventional water heaters, which can decrease efficiency and lead to premature failure. Leaks from the tank or the pressure relief valve are also common. For tankless systems, mineral deposits can sometimes cause flow restrictions. Regular servicing helps prevent these problems.

Is it worth it to repair a hot water heater?

It's often worth repairing minor issues on a newer water heater, as it can be more cost-effective than a full replacement. However, if the tank itself is compromised, or if the unit is quite old, investing in a new, more efficient model might be the better long-term financial decision. A professional can offer guidance.
