Are you tired of inconsistent water temperatures or sudden breakdowns of your tankless water heater? If you live in Markham or the surrounding areas, you may rely on your tankless water heater for hot water without the hassle of a bulky storage tank. But even the most advanced technology can face challenges.

Let’s explore the 5 most common errors in tankless water heaters, their causes, and simple solutions that can save you time, money, and frustration.

1. Mineral Buildup

Did you know that around 70% of households in Canada experience hard water issues? (Source: Municipal Water Supply Canada) Hard water, with its high mineral content, can silently disrupt the performance of your tankless water heater in Markham. Over time, minerals like calcium and magnesium accumulate inside your heater, reducing efficiency and even causing long-term damage. It's like a clogged artery in your home’s water system—causing stress on the entire system.

The Solution: To fix this problem, you should flush your water heater at least once a year. You can use a descaling solution or call a professional to handle the process. Installing a water softener is also a great long-term solution to prevent further mineral deposits.

2. Insufficient Hot Water

Imagine taking a shower after a long day, only to find that the water is cold. This frustrating experience is more common than you might think. Many homeowners with tankless water heaters in Markham often run into issues with insufficient hot water. A study by the Department of Energy found that the size of the unit is critical to meeting your household's needs. If you have multiple bathrooms or high water demands, your tankless unit may not be large enough to keep up.

The Solution:

- Assess your water needs based on the number of bathrooms and appliances in your home.

- Upgrade to a unit with a higher flow rate if your current system is struggling.

- Consult with a professional HVAC contractor like Air Leaders, who can help you select the perfect system for your home.

3. Cold Water Sandwich

Have you ever experienced the "cold water sandwich"? This happens when your tankless water heater’s heating cycle takes too long, causing cold water to flow through the pipes before the hot water arrives briefly. It’s like biting into a sandwich that’s been turned upside down—definitely not what you were expecting.

The Solution: To avoid the cold-water sandwich, consider installing a recirculation pump in your tankless system. Newer tankless water heaters have built-in features to reduce lag time. You can also install a small storage tank to maintain consistent water temperatures during peak demand.

4. Error Codes and Faulty Sensors

Error codes can be cryptic and frustrating, but they’re your water heater’s way of saying, “Help me!” Tankless systems are equipped with sensors that monitor temperature, pressure, and airflow. When something goes wrong, the system displays an error code.

Some common error codes are:

- Error Code 10: Venting issues.

- Error Code 11: Ignition failure.

- Error Code 12: Overheating.

The Solution:

- Regularly check your unit’s filters and clean them as needed.

- Make sure your venting system is clear and functioning correctly.

- Consult your system’s manual or call a professional like Air Leaders to troubleshoot error codes effectively.

5. Low Water Pressure

Have you noticed your shower doesn’t have the same pressure it used to? Low water pressure can severely affect the performance of your tankless water heater. When the water pressure drops below 30 PSI, your heater may struggle to heat water properly, leading to uneven temperatures and long wait times.

Low water pressure is common for homes with older plumbing systems or clogged filters. If you live in an area with fluctuating water pressure, this could be your problem.

The Solution:

- Check the water pressure in your home and ensure it falls between 40-60 PSI.

- Clean or replace the inlet filters regularly.

- Hire a certified HVAC technician to inspect your system and fix any underlying issues with the plumbing or water pressure.
