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

Electric tankless heaters provide a steady stream of hot water using high-voltage heating elements. Because they require significant power, we ensure your home’s electrical panel can handle the load before installation or repair. You need this service if the unit is losing power or failing to heat during peak 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 Scottsdale

How long do hot water heaters typically last?

Traditional tank water heaters generally last between 10 to 15 years. Electric tankless water heaters, with proper maintenance, can often last 20 years or more. This longer lifespan is a compelling reason to consider a tankless system for your Scottsdale residence. Regular servicing ensures they perform optimally throughout their operational life.

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

What is the most efficient type of water heater?

Electric tankless water heaters are among the most efficient options because they heat water only when it's needed, eliminating the standby energy loss associated with traditional tank heaters. This on-demand heating ensures you have hot water whenever you need it without continuously consuming energy to keep a large tank heated.

What are signs I need a new water heater?

Common indicators that you need a new water heater include a significant decrease in hot water supply, rusty or discolored hot water, or unusual noises from the unit. If your current water heater is over 10-15 years old or has persistent leaks, replacement is likely the most practical solution. These issues can escalate if left unaddressed.

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

Sediment buildup at the bottom of the tank is a frequent issue for standard water heaters, reducing efficiency and causing noise. For tankless units, mineral scale can accumulate if they aren't flushed periodically, impacting performance. Both types can also suffer from heating element or thermostat malfunctions.

Is it worth it to repair a hot water heater?

Repairing a water heater is often a sensible choice for minor issues on relatively new units. However, if your water heater is aging and experiencing multiple problems, the cumulative cost of repairs can exceed the price of a new, more efficient system. For Scottsdale homes, investing in a new electric tankless unit can be more cost-effective in the long run.
