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

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 Irvine

How long do hot water heaters typically last?

Traditional tank water heaters usually last between 10 to 15 years. Tankless models, while a larger initial investment, can offer a lifespan of 20 years or more with proper maintenance. This longevity can be a significant factor for homeowners in Irvine planning for long-term home improvements.

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 choice. They heat water only when needed, eliminating standby energy losses common with tank models. This on-demand heating can lead to considerable energy savings for Irvine households over time, contributing to lower utility bills.

What are signs I need a new water heater?

Watch for signs like a significant drop in hot water pressure, discolored or foul-smelling hot water, and unexplained puddles around the unit. Unusual noises, such as popping or rumbling, can also indicate internal problems. If your Irvine water heater is showing these symptoms, it's time to get it checked.

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

Sediment buildup within the tank is a frequent issue that can compromise efficiency and cause noise. Other common problems include thermostat failures, issues with heating elements (in electric units), or the anode rod deteriorating. Regular servicing can help prevent these problems in your Irvine unit.

Is it worth it to repair a hot water heater?

Repairing a newer water heater for a minor issue is often cost-effective. However, if your unit is nearing the end of its typical lifespan or requires a major repair, replacement might be a better long-term investment. Professionals can assess your Irvine water heater and provide guidance on the most sensible option.
