Why Maintain? The Real Benefits
Routine maintenance of your tankless water heater is an investment that returns dividends in both cost savings and peace of mind. Maintenance guarantees your system operates longer, more efficiently and doesn’t leave you hanging with unexpected ice-cold showers.
Now, let’s unpack those underlying benefits—to make the case for why keeping things in good repair matters.
Avoid Costly Future Breakdowns
Tankless water heaters are rugged devices, but they can still have problems if you don’t take the time to check on them regularly. Neglect can cause mineral and scale buildup, which can clog the heat exchanger and interfere with operation.
When the unit is forced to operate under duress, it’s just a matter of time before it breaks down. Emergency repairs are exorbitantly more expensive than routine maintenance, and they can burden the average household budget.
To avoid these annoyances, have a list of tips at the ready. Don’t forget to flush minerals out annually, descale when buildup becomes visible, and look out for leaks or strange sounds! These actions prevent minor issues from escalating into costly expenditures.
Maintenance: Smart Money Spent
Smart, preventative maintenance translates to good energy management, less cost and fewer surprises. Tankless water heaters can operate 8% to 34% more efficiently than traditional tank water heaters—though the savings will vary based on how much hot water you use.
Basic maintenance, such as flushing the system annually, helps everything function properly and reduces energy loss. Maintenance is the smart money.
Compare this to the cost of a major repair or an early replacement—routine maintenance is far less expensive. Having a pro come in to service your heater means that all of the parts are inspected and tested. If any are worn, they’ll be swapped out, allowing your heater to last 20 years or more!
Consistent Hot Water, Zero Worries
When you maintain a consistent timetable, you enjoy consistent hot water, no stressful surprises. Showering without the hot water changing from shower to shower is a luxury that comes with proper maintenance.
If you’re starting to experience temperature fluctuations, decreased water pressure, or odd sounds coming from your plumbing, it’s time to get a check-up. Look out for signs such as inconsistent heating or error messages—these are clues your unit needs attention.
Your Tankless Longevity Checklist
A tankless water heater can give you decades of dependable service with just a few, easy-to-do maintenance tasks each year. Keeping up with these maintenance items will ensure your heater is operating safely, efficiently, and reliably.
Here’s a handy, non-tankless list of things to look for. It covers timing, so you can maximize your system’s lifespan.
1. Descale: Beat Hard Water Buildup
Mineral buildup is a major issue, particularly in hard water cities such as Los Angeles. To combat this, regularly flush your tank water heater with vinegar or a commercial descaler.
Most people descale every 6 to 12 months. If you have very hard water, go with six months. Descaling breaks up the scale that accumulates over time clogging pipes and reducing efficiency.
Be sure to keep a record of each flush so you don’t forget.
2. Clean Inlet Screen Regularly
Your tankless water heater’s inlet screen can get clogged with sediment and debris and restrict water flow. Cleaning it out every few months can ensure a better flow.
You’ll need just a small stiff brush—and perhaps some needle-nose pliers. Shut off the water, remove the screen, rinse it off and replace it.
3. Inspect All Connections Annually
Annually inspect all connections. Inspect and make note of all valves, pipes and fittings to catch any leaks or corrosion. If you see a leak or rust, address it immediately.
Make a note of any adjustments so you can monitor if they negatively impact things in the future.
4. Test Pressure Relief Valve
Pressure relief valve testing is an absolute safety requirement. Turn the valve to make sure the water comes out smoothly.
If it does stick or leak, make a note of the pressure and replace it if necessary.
5. Listen: Early Warning Sounds
Understand what your heater should sound like in good health. If you’re hearing banging, whistling or clicking, you may need to look for clogs or loose components.
Keep tabs on strange sounds and what they could indicate.
Water Quality: Heater’s Nemesis?
Water quality is an important consideration that can determine a tankless water heater’s lifespan. In areas like Arizona where hard water is more prevalent, this has a tangible effect on the operational aspect of these systems. In addition to other negative effects on water quality, scale and mineral buildup would hinder heating and decrease the overall lifespan of the system.
Get to know the quality of your local water supply! Addressing these problems will make it more likely that your heater will last 15–25 years or longer.
Hard Water’s Toll Explained
Hard water usually deposits calcium and magnesium. These minerals precipitate out and build up inside the unit, coating heating elements and forcing them to work harder. The heater consumes more energy and is unable to maintain temperature.
This results in increased costs and a less reliable supply of hot water. If you notice lower hot water flow, clicking sounds, or water that goes hot and cold, scale might be the cause. Descaling at least once a year, particularly if you live in an area with hard water, prevents limescale buildup and maintains consistent performance.
Water Softeners: A Wise Choice?
A typical water softener replaces the hard water minerals with sodium or potassium. This switch can be a lifesaver for tankless systems! Salt-based softeners are best suited for treating extreme mineral concentrations.
Conversely, salt-free softeners are lower maintenance, but they can’t dissolve all of the buildup. Consider your home’s size, plumbing situation, and your salt budget before purchasing. Soft water leads to less scale build up and therefore less damage, which means lower repair costs.
Know Your Local Water
Finding out what minerals or chemicals are in your supply is as easy as checking your city’s most recent water report. For instance, if you notice elevated levels of calcium or chlorine, these can damage your heater.
Determine whether you need a softener, a filter, or both with local reports written to address your specific locality. Customize your approach based on local conditions to maximize efficiency and system longevity.
When to Call a Pro
Learning when to call a pro can go a long way. It will save you a ton of hassle and really double the lifespan of your tankless WH! Though many are simple enough for the average homeowner, there are some problems that require a professional touch.
Regular professional help makes it safer, but that helps your heater last longer and work more efficiently.
The Essential Annual Service
There’s nothing more helpful than an annual service from a trained professional. This visit is the complete check-up.
We’ll clean and inspect the heat exchanger, reverse flush scale, clean air and water filters, check for leaks and more. A pro will look at electrical and gas connections to identify any loose fittings or deterioration.
It’s a good idea to keep a log of every service, as well. It can assist when filing warranty claims and prove that you’ve performed the necessary maintenance.
Red Flags: Heater Needs Help
Keep an eye out for things such as strange sounds, water pooling around the heater, or a rapid loss in hot water supply. If your system is sputtering out lukewarm water or is frequently shutting down, it’s time to call a professional.
These red flags usually indicate deeper issues—mineral scale, valve malfunctions, or faulty sensors. If you’re not confident in repairing these, a licensed plumber can take care of it quickly and safely.
DIY vs. Pro: Safety First
Basic maintenance, such as cleaning the surface with a damp cloth or removing any dust, is acceptable for owners. Descaling, filter replacement, or repairing gas or electric components can be dangerous.
A Pro has the right equipment and experience for these type of jobs. If you decide to attempt small repairs, always turn off power and water supply first, and consult the appliance’s user manual.
For anything more complicated, or if you are simply uncertain, it’s worth seeking professional assistance.
Installation: Foundation for Durability
A solid installation leaves a tankless water heater positioned for years of dependable performance. Proper installation isn’t just about not following the manual—it’s a matter of right sizing, proper safe venting, and choosing the right skilled hands. Each step ensures that the unit has a longer life expectancy.
It reduces the need for future maintenance, which is a big deal in a warm climate or during crisp Los Angeles evenings.
Proper Sizing Prevents Strain
Proper sizing isn’t just a matter of getting the right attic space. A small tankless water heater will not serve the demand effectively. It lags, wears out faster than anticipated, and provides spotty hot water.
If it’s too large, you’re spending too much energy and money. First, consider peak water use—how many showers, faucets, toilets, and appliances will be on simultaneously. For a typical home, a unit that delivers 7–10 gallons per minute is usually sufficient, but be sure to verify your requirements.
Most manufacturers have sizing charts or calculators online. Proper sizing prevents strain and provides superior performance.
Correct Venting is Crucial
Proper venting helps ensure your home is safe and your system operates efficiently. Inadequate venting can allow harmful carbon monoxide to pool and destroy efficiency.
Check for vent pipes that are well sealed, not blocked, and code compliant. The most common errors are using the wrong materials or omitting clearances. A venting checklist should call for checking vent pipe slope, distance from walls, and daily inspection for leaks.
Choose Certified Installers Only
Certified installers are familiar with local codes and best practices. They identify other problems that can lead to premature failure of a heater, such as lack of insulation or incorrect anode rod installation.
Inquire as to whether or not installers are licensed, insured, and experienced in installation with your brand. Quality professionals provide detailed estimates and service proposals.
You can browse manufacturer websites or look on trade group websites to find trusted installers or providers.
Our Pro Tips for Peak Performance
Maximizing your tankless water heater begins with regular maintenance and a few professional techniques. Staying ahead of routine maintenance saves time and keeps your system working as long as possible. Proper maintenance reduces energy consumption and the chance of unexpected failures.
Read on for a few of those steps and tips you can implement in your own backyard.
Eco-Clean: Vinegar Solution
Cleaning with a vinegar solution is a easy, green solution to descaling your system. To descale, turn off the electricity, shut off the water, then run hoses to the service valves. If using a small pump, run pure white vinegar through the unit for 45 minutes to an hour.
This helps dissolve any mineral buildup that may be clogging your heater and slowing it down. Considering hard water is the norm in most Los Angeles homes, try to make this a semiannual chore. For softer water, once a year is sufficient.
Smart Settings Save Energy
Properly setting your water temperature will save you energy and help prolong the life of your heater. In most homes, 120°F–125°F will provide optimal comfort with substantial energy savings. This is plenty hot for taking showers and washing dishes, but not so hot that it’s wasteful.
Most units are equipped with digital controls—take advantage of this to program a weekly schedule if your family’s requirements fluctuate. For optimal performance, do your best to maintain consistent water pressure, between 30 and 80 psi.
Decode Your Manufacturer’s Guide
There’s a lot more to the manufacturers’ manuals than just installation instructions! Watch for information on filter cleaning, vent inspection and freeze protection. Most manufacturers recommend regularly cleaning filters every few months and draining the system at least once a year.
Perform only these simple tasks and look for changes in water pressure or temperature fluctuations.
