 Frequently Asked Water Heater Questions

How does a tankless water heater work?

Instead of heating and storing water, a tankless unit warms it as it flows through special coils or burners. Cold water runs past those elements, producing hot water instantly. You get as much as you need, whenever you need it, without waiting for a refill.

Are tankless systems worth it?

They are if you plan to stay in your home for several years. Tankless systems use up to 40% less energy than standard models and can last twice as long. The energy savings and fewer repairs often balance out the higher installation cost over time.

Can I still run out of hot water?

Only if the system is too small for your household. When we install your unit, we size it based on your home’s usage, including showers to laundry and dishwashing. That way, your hot water never cuts out, even with multiple fixtures running.

What kind of maintenance does it need?

Most units need flushing once a year to remove scale from Rancho Cucamonga’s mineral-heavy water. We also clean filters, check ignition systems, and test pressure valves. Regular maintenance keeps your water heater efficient and prevents costly repairs later.

What are signs my system needs repair?

You might notice lukewarm water, fluctuating temperatures, or clicking sounds while it’s running. Some models display error codes when something’s off. Calling early for water heater repair in Rancho Cucamonga usually means a faster, simpler fix.

Can I replace my old tank system with a tankless one?

Yes, and we handle the full conversion process. We’ll remove the old tank, adjust gas or electric lines, and set up new venting as needed. Once installed, you’ll notice steady water temperature, faster recovery, and improved efficiency right away.

How long do tankless water heaters last?

Most systems last around 20 to 25 years with regular flushing and inspection. Keeping up with service helps protect internal parts from corrosion and scale. With proper care, your tankless system can easily outlast traditional water heaters by a decade or more.

Is a Tankless Water Heater Right for You?

Tankless systems are perfect for households that use hot water throughout the day or anyone looking to save space and energy. They’re reliable, quiet, and built to last. Our experts will break down the upfront cost, long-term savings, and what setup makes the most sense for your home. From water heater replacement in Rancho Cucamonga to ongoing service, Ground Werks Plumbing and Rooter helps you get it right the first time.
