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 you switch to a tankless system, the installation price covers the labor required to modify your gas lines, upgrade venting, and configure the plumbing. Costs typically vary based on the complexity of your current setup and the capacity of the unit you choose. A professional technician will need to assess your home's layout to provide an accurate estimate for these modifications. 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?

Most traditional tank water heaters last between 8 to 12 years. Tankless models can often last 20 years or more with proper maintenance. Factors like water quality and usage habits in Gilbert can influence this lifespan. Regular check-ups can help maximize your current unit's performance.

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 the most efficient, as they heat water on demand. This means you aren't constantly heating a large tank of water. High-efficiency tank models also exist, offering better performance than older units. A pro can help determine the best fit for your Gilbert household.

What are signs I need a new water heater?

Look for signs like rusty water, leaks around the base of the tank, or a significant decrease in hot water supply. These issues can become more common as units age.

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

Sediment buildup at the bottom of the tank is a very common issue, leading to reduced efficiency and strange noises. Other frequent problems include thermostat malfunctions and issues with the heating element or pilot light. Regular flushing can help prevent sediment buildup.

Is it worth it to repair a water heater?

Repairing a water heater is often worthwhile if the issue is minor and the unit is relatively new. However, if your heater is old or requires significant repairs, a replacement might be more cost-effective in the long run. A pro can assess the situation and advise you.
