How Often Should I Have My Hot Water Heater Checked by a Professional?

Regular maintenance of your hot water heater is crucial for its longevity and efficiency. This article will explore the recommended maintenance schedule for both traditional tank water heaters and newer solar options, addressing common issues and offering practical advice.

Understanding the Lifespan and Maintenance of Traditional Gas Water Heaters

When you purchase a tank water heater, it typically comes with a warranty of around 12 years. However, many water heaters fail to reach this full lifespan due to various factors. These can include rusting, leaks, and ignition system failures. Typically, a gas water heater will rust out and leak after around 5-10 years, necessitating a replacement.

Periodic maintenance is essential to ensure your water heater operates efficiently and safely. It is advisable to schedule a professional diagnostic check when you notice any issues, such as unusual noises or decreased hot water flow. Regular inspections can help catch and fix problems before they become more severe.

The Mystery of a Solar Water Heater

Five years ago, you installed a solar water heater as a backup for your tank water heater. While the system appeared to be a good idea, it has since raised more questions than answers. The solar water heater has features such as recirculation pumps meant to maintain water temperature at the tap, but these features have not been utilized effectively. Additionally, you are unsure if the system is even working correctly or if it has ever needed servicing.

What to Check During a Solar Water Heater Inspection

The main components of a solar water heater include the storage tank, solar panels, and a control system. A professional diagnostic service can check for:

Is the storage tank properly insulated? Are the solar panels collecting enough sunlight? Does the control system (circuit board) function correctly? Are there any leaks in the system?

Given the complexity of solar systems, it is important to consult a specialist who is experienced with these installations.

Common Maintenance Tasks for Hot Water Heaters

For traditional tank water heaters, there are a few key maintenance tasks that can be performed. These include:

Checking for water leakage around the bottom of the tank. Rust build-up inside the drain valve can also be a sign of internal rusting. Opening the drain valve to release any rust or mineral buildup. If the initial release appears rusty, continue draining until the water runs clear. Using a bent metal hanger to probe the drain valve if the clog is too thick to clear.

These steps can help diagnose whether the tank is rusting out from the inside and may indicate the need for replacement.

When Is the Right Time to Call a Professional?

While diagnostics are not always necessary, they should be considered if the water heater is not functioning properly. Common signs that it is time to call a professional include:

No hot water or inconsistent hot water supply. Strange noises from the water heater during operation. A decrease in hot water pressure. Visible rust on the water or a foul smell in the water.

Regular maintenance can help extend the life of your water heater and prevent costly repairs in the future. Given that the warranty on most water heaters is around 12 years, it is a reasonable frequency to have a professional inspect the system.

Conclusion

Proper maintenance is key to ensuring the longevity of your hot water heater. By understanding the typical lifespan and maintenance requirements, you can make informed decisions about when to schedule professional inspections and repairs. For solar water heaters, it is especially important to consult with a specialist who can address the unique needs and complexities of these systems.
