Do you enjoy taking hot showers every day? If so, you might benefit from a tankless water heater in your home.
Tankless water heaters are an excellent investment because they provide hot water on demand without storing a large water tank. However, like any other appliance, tankless water heaters require regular maintenance to ensure they continue functioning at their best.
Without proper maintenance, you may experience reduced water flow, inconsistent hot water, or even a complete unit breakdown.
In this article, we will discuss the essential steps you need to take to maintain your tankless water heater and keep it running smoothly for years to come.
So, whether you’re a new owner of a tankless water heater or looking to improve your current maintenance routine, keep reading to discover our expert tips and tricks.
Benefits of Having a Tankless Water Heater
Before we dive into the essential maintenance steps for your tankless water heater, let’s first talk about why you should invest in a tankless water heater in the first place. There are several benefits to having a tankless water heater, including:
Energy Efficiency
One of the main advantages of having a tankless water heater is that they are much more energy-efficient than traditional tank water heaters.
Tankless water heaters only heat water when needed, rather than constantly keeping a large tank hot. This means you’ll save money on your energy bill each month while also reducing your carbon footprint.
Space-Saving
Another benefit of tankless water heaters is that they take up much less space than traditional ones.
They don’t require a large tank to store water, so you can install them in smaller spaces, such as closets or utility rooms.
Longevity
Finally, tankless water heaters typically have a longer lifespan than traditional ones.
While traditional water heaters may only last 8–12 years, tankless water heaters can last up to 20 years with proper maintenance. This means you’ll save money in the long run by not having to replace your water heater as often.
Why Tankless Water Heaters Require Maintenance
While tankless water heaters are more energy-efficient and have a longer lifespan than traditional ones, they still require regular maintenance to function at their best.
Without proper maintenance, you may experience reduced water flow, inconsistent hot water, or even a complete unit breakdown.
Tankless water heaters require maintenance because they heat water differently than traditional tank water heaters.
Tankless water heaters use a heat exchanger to heat the water as it passes through the unit. Over time, minerals and sediment can build up on the heat exchanger, which can reduce its efficiency and eventually lead to a breakdown of the unit.
Additionally, tankless water heaters have a water filter that needs to be cleaned regularly to prevent clogs and ensure proper water flow. The venting system must also be inspected to ensure it is clear of debris and functioning properly.
Tankless Water Heater Maintenance Checklist
Now that you understand why tankless water heaters require maintenance, let’s go over the essential steps you need to take to keep your unit running smoothly.
Here is a checklist of the maintenance tasks you should perform on your tankless water heater:
Flushing the tankless water heater
One of the most essential maintenance tasks for your tankless water heater is flushing the unit regularly. Flushing the unit helps to remove any mineral buildup on the heat exchanger and ensures that your unit is functioning at its best.
To flush your tankless water heater, turn off the power source and shut off the water supply to the unit.
Then, attach a hose to the unit’s cold water inlet and drain valves. Open the drain valve and let the water flow out of the unit for at least 20 minutes.
Once the water runs clear, close the drain valve and remove the hose. Finally, turn the water supply back on and restore power to the unit.
Cleaning the Water Filter
Another essential maintenance task for your tankless water heater is cleaning the filter.
The water filter helps prevent sediment and debris from entering the unit and causing clogs. Over time, the water filter can become clogged and reduce water flow to the unit.
To clean the water filter, turn off the power source and shut off the water supply to the unit. Locate the water filter and remove it from the unit.
Rinse the filter under running water until clean, then reattach it to the unit.
Inspecting the Venting System
The venting system is essential to your tankless water heater, as it helps ensure exhaust gases are safely removed from your home. Over time, debris can build up in the venting system and reduce efficiency.
To inspect the venting system, turn off the power source and shut off the water supply to the unit. Locate the venting system and inspect it for any signs of damage or debris buildup.
If you notice any issues, contact a professional to repair or clean the venting system.
Checking the Pressure Relief Valve
The pressure relief valve is an important safety feature of your tankless water heater, as it helps to prevent the unit from overheating and potentially causing a fire or explosion. The pressure relief valve should be checked regularly to ensure it functions properly.
To check the pressure relief valve, turn off the power source and shut off the water supply to the unit.
Locate the pressure relief valve and lift the lever to allow water to flow out of the valve. If water does not flow out of the valve or is damaged, contact a professional to replace the valve.
Maintaining the Heat Exchanger
As we mentioned earlier, the heat exchanger is an essential component of your tankless water heater, as it heats the water as it passes through the unit.
Over time, minerals and sediment can build up on the heat exchanger, reducing efficiency.
To maintain the heat exchanger, you should flush the unit regularly, as discussed earlier. Additionally, you can use a descaling solution to remove any stubborn mineral buildup on the heat exchanger.
Follow the manufacturer’s instructions for using the descaling solution, and rinse the unit thoroughly after using the solution.
Troubleshooting Common Tankless Water Heater Issues
Even with regular maintenance, you may still need help with your tankless water heater occasionally. Here are some common issues you may encounter and how to troubleshoot them:
Reduced Water Flow
If you notice reduced water flow from your tankless water heater, it may be due to a clogged water filter or a buildup of mineral deposits on the heat exchanger. Try cleaning the water filter and flushing the unit to see if this resolves the issue.
Inconsistent Hot Water
If you are experiencing inconsistent hot water from your tankless water heater, it may be due to a malfunctioning sensor or a buildup of mineral deposits on the heat exchanger.
Try flushing the unit and cleaning the heat exchanger to see if this resolves the issue. If you need help, contact a professional to inspect the unit.
Complete Breakdown of the Unit
If your tankless water heater has completely broken down, it may be due to a malfunctioning component or a buildup of mineral deposits on the heat exchanger.
Try flushing the unit and cleaning the heat exchanger to see if this resolves the issue. If not, contact a professional to inspect the unit and make any necessary repairs.
