What affects the price

The final price for a new water heater depends on a few moving parts. First, you have to choose the right fuel source—gas or electric—and decide if you want to stick with a standard tank or upgrade to a tankless model. We also look at the physical space where it sits and whether your current venting or gas lines meet modern safety codes. If we need to move the unit or upgrade plumbing to get it up to speed, that shifts the labor involved. Exact pricing confirmed free on the call.

About this service

Navien units are sophisticated systems that require specialized knowledge to troubleshoot. If your unit displays an error code, has reduced flow, or fails to ignite, a technician should inspect the heat exchanger and sensors. You typically need this service when the water temperature fluctuates or the unit stops responding entirely. Proper maintenance ensures these high-efficiency systems continue running as intended. Exact pricing confirmed free on the call.

While you might not think about hot water as much in the summer, it is a great time to evaluate your system’s health. Because the incoming groundwater is warmer, your heater doesn't have to work as hard, making it a stress-free window to replace an aging unit before you hit the busy autumn season.

Frequently asked in Miami

How long do hot water heaters typically last?

Navien tankless water heaters are designed for longevity, often providing 15 to 20 years of service. This lifespan is influenced by factors such as water quality and consistent professional maintenance. Addressing minor issues promptly can prevent them from becoming major, costly repairs. It's a smart investment for your home's comfort.

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

Tankless water heaters, such as those manufactured by Navien, are highly energy-efficient. They heat water only when you need it, eliminating the standby energy losses common with traditional tank heaters. For Miami residents seeking to lower their energy bills, this offers a significant advantage. Consider the long-term savings.

What are signs I need a new water heater?

Look for consistent signs like a lack of hot water, fluctuating temperatures, or visible leaks around the unit. Unusual noises or a metallic odor in your hot water are also strong indicators of a potential problem. Your Navien may display specific error codes, signaling an issue that requires immediate attention. Don't delay in seeking service.

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

Mineral buildup, or scaling, is a frequent issue for all water heater types, reducing efficiency and potentially causing damage. For Navien tankless units, this can clog the heat exchanger, impacting performance. Regular professional descaling is crucial for maintaining optimal function. This preventative care is essential.

Is it worth it to repair a hot water heater?

Repairing your Navien water heater is often a cost-effective solution, particularly for newer units or less severe problems. A qualified technician can accurately assess the situation and advise on the most economical solution. If the repair costs approach those of a new unit for an older appliance, replacement might be the more financially sound decision in the long run. Seek expert advice.
