One essential aspect of maintaining your water heater is descaling it at least once a year. Descaling involves flushing the system with a mixture of white distilled vinegar or another approved cleaning solution to remove damaging mineral deposits and sediment that can accumulate. This process will not only protect your heat exchanger from premature failure but also ensure optimal performance so you can enjoy endless hot showers without interruption!
Other routine tasks include cleaning the air filter, dirt trap, and water filter as well as ensuring there’s sufficient fresh air supply for combustion purposes. Remember that a well-maintained tankless unit has the potential to last 20+ years – much longer than their storage-tank counterparts – so investing time in proper upkeep is definitely worth it.

If you need assistance with any of these tasks or are unsure how to proceed, don’t hesitate to reach out to professionals like True Plumbing for help in maintaining or installing a new system in Atlanta.
Understanding Water Hardness
It’s crucial to understand water hardness, as it can greatly impact the performance and longevity of your tankless system. Water hardness refers to the concentration of minerals, particularly calcium and magnesium, in your water supply. These minerals can build up inside your tankless water heater over time, causing calcified deposits that hinder heat transfer efficiency and potentially damage the unit. Therefore, it’s essential to regularly maintain a tankless water heater to prevent hard water issues from affecting its performance.

To help you better grasp the concept of water hardness and how it affects your tankless system, consider these key points:
– Hard water causes mineral deposits to accumulate on heat exchangers, reducing their ability to efficiently transfer heat.
– The more severe the hard water problem is in your area, the more frequently you should flush your tankless unit.
– Installing a water softener can help reduce the negative effects of hard water on your tankless system.
By understanding how hard water impacts your tankless water heater and taking steps to mitigate those effects through regular maintenance or installing a softener if needed, you’ll ensure that you get endless hot showers for years while also extending the lifespan of your unit. So don’t let hard water be an obstacle – stay informed and take action to keep enjoying all that a tankless hot-water system has to offer.
Descaling Your Heater (Flushing)
So you’ve decided to descale your heater, and that’s a smart move for keeping it running smoothly and efficiently. Descaling your tankless hot water heater involves flushing the water heater with a solution, typically white vinegar, or a system descaling solution to remove mineral buildup from inside the unit.
To get started, you’ll need a descaling kit which includes a submersible pump, hoses, and ideally some Flow-Aide for even better results. You can also use white distilled vinegar if you don’t have Flow-Aide on hand. It’s important to follow the manufacturer’s instructions when using a descaling kit to ensure proper maintenance.
Safety First: Before you begin, make sure to turn off the power or gas to your water heater to prevent any accidental shocks. Also, wear protective gloves and eyewear to protect yourself from the descaling solution.
Materials You’ll Need:
- Descaling solution (you can purchase a commercial descaling solution or use a vinegar solution)
- A bucket
- A small pump
- Two hoses
Step-by-Step Descaling Process:
- Turn Off the Heater: Make sure the heater is turned off and cool before you start the descaling process.
- Prepare the Descaling Solution: Prepare your descaling solution according to the instructions on the package. If you’re using a vinegar solution, a 50/50 mixture of white vinegar and water should suffice.
- Disconnect the Water Pipes: Disconnect the hot and cold water pipes from your heater. Be sure to turn off the water valves first to prevent any water from flowing out.
- Connect the Hoses: Connect one hose to the hot water valve and the other to the cold water valve. Place the other ends of the hoses in your bucket.
- Add the Descaling Solution: Pour your descaling solution into the bucket. Make sure there’s enough solution to cover the ends of the hoses.
- Start the Pump: Turn on the pump to circulate the descaling solution through your water heater. Let the solution circulate for about 30-45 minutes to dissolve the mineral deposits.
- Flush the Heater: After descaling, remove the hoses and reconnect the water pipes. Then, flush the heater with clean water to remove any remaining descaling solution.
- Turn On the Heater: Once you’ve finished flushing the heater, you can turn it back on. Check for any error codes or issues to ensure everything is working correctly.
Flushing the water heater should be done at least once a year or more frequently if you have hard water issues. Regularly performing this essential maintenance will prolong the life of your unit while ensuring optimal performance throughout its lifespan.
Remember, while descaling is a task that many homeowners can do themselves, it’s always best to call a professional if you’re unsure or uncomfortable performing this task.
Cleaning the Air Filter
Another important step in keeping your unit running smoothly is cleaning the air filter. Your tankless water heater relies on a steady supply of fresh air to operate efficiently, and a clogged or dirty air filter can impede that flow, causing potential damage to your system. Regular maintenance of the air filter ensures proper water heating performance and helps extend the life of your investment.
To clean the air filter, follow these simple steps:
1. Locate the air filter on your tankless water heater. It may be in a different location depending on your specific unit model.
2. Turn off the power supply to avoid any electrical hazards while handling internal components.
3. Carefully remove the air filter from its position, taking note of any clips or fasteners holding it in place.
4. Clean the filter using a soft brush or vacuum attachment to remove dust and debris gently without damaging it.
Once you’ve thoroughly cleaned the air filter, reinstall it securely into its original position within your tankless water heater system and turn the power back on. By regularly incorporating this maintenance task into your routine schedule, you’ll ensure optimal performance from your tankless water heater, providing endless hot water for years to come while also fostering a sense of belonging and satisfaction in knowing that you’re proactively caring for an essential household appliance.
Cleaning the Water Filter
In addition to cleaning the air filter, you’ll also want to regularly check and clean your unit’s water filter, as this component plays a crucial role in trapping larger sediment particles that could otherwise cause damage or impede performance.

Just like with the air filter, maintenance of your tankless water heater’s water filter is essential for ensuring endless hot water supply and prolonging the lifespan of your unit. Don’t let your investment go to waste by neglecting this important aspect of upkeep.
Cleaning the water filter on your tankless water heater is a fairly simple process that shouldn’t take too much time. First, locate the filter – it’s usually situated near the cold-water inlet pipe. Turn off both the hot and cold-water valves before removing the filter housing or screen (depending on your model). Gently wash it using warm soapy water and a soft brush to remove any accumulated debris.
Once it’s clean, rinse thoroughly with fresh water and reinstall it in its original position. Make sure everything is securely fastened before turning the valves back on and restoring power to your tankless water heater. With proper maintenance like this, you’re one step closer to protecting your valuable investment while ensuring consistent performance for years to come!
Cleaning Out the Dirt Trap
Don’t forget about the dirt trap, as it’s a critical component that needs attention too! Just like the water filter, your tankless water heater’s dirt trap plays an essential role in maintaining its efficiency and prolonging its lifespan. The dirt trap is usually located underneath the unit and is designed to catch larger debris and sediment before they enter the heat exchanger. By regularly cleaning out this part of your system, you can prevent potential damage caused by these particles.
To clean the dirt trap, follow these essential tips:
– First, make sure to turn off your tankless water heater and disconnect it from any power source for safety reasons.
– Then, locate the dirt trap beneath your unit – it typically looks like a small cylindrical piece with a mesh screen inside.
* Carefully remove the trap from its housing by unscrewing or unclipping it.
* Rinse out any debris caught in the mesh screen under running water.
* If necessary, use a soft brush to gently scrub away stubborn sediment buildup.
* Once thoroughly cleaned, replace the dirt trap back into its housing and secure it properly.
By incorporating regular maintenance tasks like cleaning out your tankless water heater’s dirt trap into your routine, you’re taking steps towards ensuring optimal performance and extending the lifespan of the water heater.
Remember that staying on top of these essential tips for maintaining your system will not only save you money in repairs but also provide you with an endless supply of hot water when you need it most.
