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 Tempe

How long do hot water heaters typically last?

Traditional tank water heaters usually last between 8 to 12 years. Tankless water heaters, however, can often offer a lifespan of 15 to 20 years or even longer with consistent maintenance. The hard water conditions sometimes found in the Tempe area can affect longevity. Regular professional inspections are beneficial.

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

The cost to install a new water heater in Tempe depends on various factors. These include the type of unit (tank or tankless), its size, and the complexity of the installation. The brand chosen and any necessary modifications to your existing plumbing or gas lines will also influence the total price. A professional assessment is needed for an accurate quote.

What is the most efficient type of water heater?

Tankless water heaters are generally considered the most energy-efficient type available. They heat water on demand, meaning you only use energy when hot water is actually needed, avoiding standby heat loss. This can lead to substantial savings on utility bills for Tempe residents. They represent a modern, efficient approach.

What are signs I need a new water heater?

Several signs indicate it might be time to replace your water heater. These include visible leaks around the unit, a significant decrease in hot water availability, or unusual noises like popping or rumbling. Discolored or rusty hot water is also a strong indicator that the tank may be failing. Don't delay addressing these issues.

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

Sediment buildup at the bottom of a traditional tank is a common cause of issues, leading to reduced efficiency and noise. Problems with the thermostat or heating elements are also frequently encountered. For tankless models, scale buildup and issues with the ignition or pilot light are more typical concerns.

Is it worth it to repair a hot water heater?

The decision to repair your water heater in Tempe depends on its age and the nature of the problem. Minor repairs on a newer unit are often a cost-effective solution. However, if your heater is older and requires major repairs, a replacement might be a better long-term investment. Consulting a professional can help you decide.
