Benefits of Choosing a Tankless Water Heater

Tankless water heaters only heat water as it is needed. When you turn on a faucet or start the washing machine or dishwasher, the heating process is started instantly. This means you are not limited to the water that can be held in a storage tank. You will have plenty of hot water and save money, since tankless water heaters generate more hot water with much less energy.

Tankless water heaters offer:

• Instant access to hot water
• A smaller size that takes up less space
• Lower energy costs
• Less frequent repairs
• Twice the lifespan of a traditional water heater

If you frequently run out of hot water or want to reduce energy consumption for financial or environmental reasons, a tankless water heater may be the ideal choice for your home. Although these water heaters are more expensive than a traditional water heater with a storage tank, they can last for up to 20 years. Because they cost less to operate and have double the lifespan, you can expect a great return on investment.

Signs You Need a New Tankless Water Heater

A tankless water heater is built to last, but even the best systems eventually need replacement. Recognizing the signs of a failing unit can help you avoid unexpected breakdowns and costly emergency repairs.

Key Indicators It’s Time for a Replacement:

• Inconsistent Water Temperature – If your hot water fluctuates between warm and cold without reason, it may indicate a failing heating element or internal component issues.
• Reduced Hot Water Supply – When your tankless water heater struggles to meet demand, even with normal usage, it could mean the unit is no longer operating efficiently.
• Frequent Repairs – If you’re calling for repairs more often, investing in a new unit may be more cost-effective than continually fixing an aging system.
• Error Codes & System Failures – Recurring error messages on your unit often signal a deeper issue, such as sensor malfunctions or exhaust blockages, which can impact performance.
• Increased Energy Bills – A sudden spike in your utility costs without changes in usage may mean your heater is losing efficiency and working harder to produce hot water.
• Old Age – Most tankless water heaters last 15-20 years. If your unit is approaching this age, upgrading to a new model can improve efficiency and reliability.

Commonly Asked Questions

How does a tankless water heater work?

A tankless water heater heats water on demand instead of storing it in a tank. When you turn on a hot water tap, cold water flows through a heating element, which quickly raises the temperature to provide an endless supply of hot water. This process improves energy efficiency and eliminates standby heat loss.

What size tankless water heater do I need?

The right size depends on your household’s hot water demand. Consider factors like the number of bathrooms, appliances that use hot water, and flow rate in gallons per minute (GPM). A professional assessment can ensure you choose a unit that meets your needs without overloading your system.

How often should a tankless water heater be serviced?

Regular maintenance is crucial to keep your tankless water heater running efficiently. It’s recommended to flush the system once a year to remove mineral buildup, clean the inlet screen filter, and inspect key components. Homes with hard water may require more frequent descaling to prevent damage.

Are tankless water heaters more expensive to install?

While the initial installation cost is higher than traditional water heaters, tankless models offer long-term savings. Their energy efficiency, lower utility bills, and longer lifespan (up to 20 years) make them a cost-effective choice over time.

Can I replace my traditional water heater with a tankless model?

Yes, but it may require adjustments to your plumbing and gas lines. Tankless water heaters have different venting and power requirements, so professional installation ensures safe and efficient operation. Our experts can assess your home and provide a seamless upgrade.

Do tankless water heaters work during power outages?

Gas-powered tankless water heaters still require electricity for ignition and operation. If you experience frequent power outages, consider a backup generator to maintain hot water access during emergencies.

How does Rancho Cucamonga’s water quality affect my tankless water heater?

Rancho Cucamonga has moderately hard water, which can cause mineral buildup inside your tankless water heater. Regular flushing and installing a water softener can help prevent scale accumulation and extend the lifespan of your unit.
