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 Gilbert

How long do hot water heaters typically last?

Traditional tank water heaters generally last 10-15 years. Tankless models, however, can often last 20 years or more with proper maintenance. Understanding the lifespan helps you plan for replacements in your Gilbert home. This proactive approach can save you from unexpected breakdowns.

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. They heat water on demand, meaning you're not constantly heating and reheating water in a tank. This can lead to significant energy savings over time for your Gilbert household. Ask about ENERGY STAR certified models when you call.

What are signs I need a new water heater?

Common signs include a lack of hot water, rust-colored water, or leaks around the base of the unit. If you notice strange noises like popping or banging, it's also a warning sign. Age is another factor, as older units are more prone to failure. Proactive replacement can prevent water damage.

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

For tanked units, sediment buildup is a very common issue, leading to reduced efficiency and strange noises. For tankless models, mineral buildup can restrict water flow. Both types can experience issues with heating elements or thermostats. Regular flushing can prevent many problems.

Is it worth it to repair a hot water heater?

Repairing a water heater is often worth it if the issue is minor and the unit is relatively new. However, if the repairs are extensive or the unit is nearing the end of its lifespan, replacement might be more cost-effective. Consider the age and condition of your current system in Gilbert.
