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

A tankless water heater heats water only as it passes through the unit, saving space and energy by eliminating a storage tank. This is a great choice if you want endless hot water or are looking to lower your monthly utility bills. Installing one involves upgrading gas lines or electrical circuits to meet the unit's power needs. Total costs depend on the capacity required for your household. Exact pricing confirmed free on the call.

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 Gilbert

How long do hot water heaters typically last?

Most traditional tank water heaters last between 10 to 15 years. Tankless models can often last longer, sometimes up to 20 years or more with proper maintenance. The lifespan depends on water quality, usage, and how well the unit is cared for over time. Knowing this can help you plan for future replacements in your Gilbert home.

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 available. They heat water on demand, meaning they don't waste energy keeping a large tank of water hot when it's not needed. This can lead to significant energy savings over time. Consider if a tankless system is right for your hot water demands in Gilbert.

What are signs I need a new water heater?

Several signs indicate you might need a new water heater. These include inconsistent hot water temperatures, strange noises like popping or rumbling, leaks around the base, or rust-colored water. A professional can diagnose the problem.

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

The most common issues with traditional tank water heaters often involve sediment buildup at the bottom of the tank, leading to reduced efficiency and noise. Another frequent problem is a failing heating element or thermostat, which can cause no hot water or inconsistent temperatures. Leaks can also occur as the unit ages. Regular checks can help prevent these.

Is it worth it to repair a hot water heater?

Whether it's worth repairing depends on the problem and the age of the unit. Minor repairs, like replacing a faulty thermostat or heating element on a relatively new unit, can be cost-effective. However, if the tank itself is leaking or the unit is nearing the end of its lifespan, replacement is often the more economical choice in the long run. A pro can advise you.
