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.

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.

Tankless water heaters are generally considered the most efficient because they heat water on demand. This means you're not constantly heating a large tank of water. For Fontana homes looking to save on energy bills, a tankless system is often a smart choice.

What are signs I need a new water heater?

Common signs include a lack of hot water, unusual noises like banging or popping, visible rust or leaks, and discolored hot water.

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

Is it worth it to repair a water heater?
