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

A tankless water heater warms water only as you need it, rather than storing it in a large tank. This is an efficient option for homes that want to save space and reduce standby energy losses. You might consider this transition if your family has high hot water demand or if you want to optimize your utility 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 Tempe

How long do hot water heaters typically last?

In Tempe, traditional tank water heaters usually last 8-12 years, while tankless units can often provide hot water for 20 years or more with good maintenance. The dry climate can sometimes be less harsh on systems. Pay attention to any performance changes.

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

The cost to install a new water heater in Tempe depends on the unit's type, size, and any necessary plumbing or electrical work. Tankless water heaters often have a higher upfront cost but can lead to significant long-term savings on energy bills. We'll provide a detailed quote.

What is the most efficient type of water heater?

Tankless water heaters are generally considered the most efficient, heating water on demand rather than keeping a large tank hot. This 'on-demand' system can lead to substantial energy savings for Tempe households. They also offer a continuous supply of hot water.

What are signs I need a new water heater?

Common indicators include leaks around the base of the unit, discolored hot water, unusual noises, or a persistent lack of hot water. If your unit is approaching its typical lifespan, it's a good time to consider an upgrade.

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

Sediment buildup is a frequent issue, reducing efficiency and causing noise. Thermostat malfunctions can result in inconsistent water temperatures. Leaks from the tank or connections are also common problems that require professional diagnosis.

Is it worth it to repair a water heater?

Repairing a water heater can be cost-effective for newer units or minor issues like a faulty heating element. However, if your unit is older or requires extensive repairs, replacement with a more energy-efficient model may be a better long-term investment. Let us help you assess.
