A Plumber Recommends You Switch To Tankless Water Heaters | Knoxville, TN

Are you aware that you’re spending a lot of money just by heating your water? Heating your water is the second largest expense in your home, accounting for up to 15% of your utility bill. If you’re trying to save money, it’s time to think about investing in energy-efficient appliances like a tankless water heater.

Reasons to Switch to a Tankless Water Heaters

Below are the reasons why a plumber recommends you install a tankless water heater for your home. Get in touch with us if you have questions.

Lasts Longer

A conventional water heater can last up to 10 or 15 years, especially when it’s properly maintained. You can extend its life if you maintain it properly. One of the things you can do is to flush out the sediment build-up to ensure that your unit stays efficient. Otherwise, you could end up with a catastrophic leak.

Tankless water heaters, on the other hand, can last up to 20 years. This means you won’t have to keep buying a new water heater every 10 years. While they can be expensive to purchase, you do get to save more money down the road because of the energy savings. For installation, though, hire a licensed plumber only. Incorrect installation can also lead to a costly repair.

Energy Savings

If you have a conventional water heater installed in your home, this means you need to always turn it on to have hot water. This can skyrocket your utility bill. Tankless water heaters are also called on-demand water heaters, which means you use energy only when you’re turning on the faucet or the shower. There’s no standby heat loss with tankless water heaters; you get to conserve more energy.

Saves Money

No one wants to pay higher utility bills every month. With tankless water heaters, you can save up to 50% of your energy. This can add up to significant savings over time.

Why Is My Tankless Water Heater Running Cold More Quickly? Do I Need Water Heater Repair To Fix It? | Oak Ridge, TN

Have you experienced hot and cold water running from your tankless water heater? Though not uncommon, it is a problem that requires a tankless water heater repair. Your tankless water heating unit should run smoothly without delays to provide heated water on demand. If left unchecked, the issue can make the water heater less efficient, use more energy, and leave your Oak Ridge, TN home without enough supply of heated water. So, what makes the tankless water heater run cold and hot occasionally? What is the cause of the said fluctuations? How can a water heater repair help resolve the issues?

Cold Water Sandwich

One of the common issues that arise in a tankless water heater is a phenomenon called a cold-water sandwich. This is when the unit produces hot water for several seconds, followed by cooler water, and then applies warm water. You might think your tankless water heater shuts down for a few seconds. This usually arises when a hot water outlet such as a faucet or shower has just been shut off. For instance, if a family member just left a shower and you are next in line when you open the shower, the hot water in the pipes falls first.

This is followed by cold water as the unit heats the water that then starts flowing. Though this isn’t an emergency or a huge issue, if it is occurring persistently, you should have it addressed by a tankless water heater repair professional. The professional might install a secondary water heater or a hot water recirculation system to curb the issue.

Since the heat exchanger delay causes the issue, installing a return loop-to or a recirculating system to your tankless water heater will resolve the issue. However, you’ll incur higher energy bills. Hence, if you have a higher hot water need at your Oak Ridge, TN home, the only realistic and feasible solution is to replace the water heater with a higher capacity one. Remember, a correctly sized water heater can endlessly supply your home with heated water.

Incorrectly Sized Gas Line

Is your water heater gas-powered? Then the cold and hot water instances you experience might also arise if the gas line is the wrong size. In most tankless water heaters, you are required to extend the gas line to ensure an ample supply of gas. Have you already tried this, but the water heater still runs the hot and cold water? Then that could point to an incorrectly sized gas line. Hence, you need a tankless water heater repair service to inspect the unit and upgrade the gas meter to ensure that your unit gets enough hot water supply. Otherwise, you will need a gas line replacement.

Wrong Plumbing System Crossover

A tankless water heater must be directly connected to the return and supply lines. If the plumbing was incorrectly done or the pressure balancing valve requires some repairs, the cold water might flow into the heated water lines. This makes the heated water lukewarm. As a result, you will get some cold and heated water bursts until the line heats up properly after being used continuously. Without the assistance of a tankless water heater repair professional, recognizing this can be a problem.

After inspecting the water heater and noticing it has a wrong plumbing crossover, the professional has two options. They either might raise the thermostat on the tankless water heater or install the pressure balancing valve. Raising the thermostat means you’ll need to use the heated water at all outlets constantly. This allows the temperatures of your heated water to rise, heating the return line steadily. A pressure balancing valve monitors the temperature of your home’s incoming gas line. It also balances the excessive pressure whenever the cold water enters the system, eliminating the bursts of cold and hot water.

A Broken Flow Sensor

The other reason the tankless water heater might run cold and hot is a broken flow sensor. It measures the volume of water entering the unit and sends that information to the water heater control board. The controller will adjust the flame whenever it senses a burst of cold water entering the unit. Hence, you’ll get enough heated water immediately throughout your home. To fix this issue, you need a tankless water heater repair technician to inspect and pinpoint the unit. The professional inspects the thermostat, gas pressure, or water heater assembly. If the issue is a damaged or malfunctioning backflow sensor, have a tankless water heater repair technician replace the sensor.

Mineral Buildup

 The other reason you might experience bursts of cold and hot water at your Oak Ridge, TN, home is if the water heater has accumulated some sediments. This usually arises if your home receives hard water. The minerals dissolved in the water accumulate in the walls of the tankless water heater reducing its heating efficiency. This is a leading cause of water temperature issues in any water heater.

The only solution is having a water softener system installed. To resolve the issue, the plumbing professional will describe the system based on its severity. Remember, these minerals also result in corrosion of the pipes. The professional might also test the water for hardness and make various recommendations, such as changing the water utility provider or installing an ion exchange water softener to safeguard your plumbing.

Let the Reliable Plumbing Service Provider Help

Whenever they notice they are getting these bursts of heated and cold water, some homeowners resort to inspecting the tankless water heater themselves. However, at My Professional Plumber, we highly advise against this. Instead, let our tankless water heater repair professionals help. 

With their many years of experience, up-to-date tools, and training, they are in a better position to resolve the issue. The tankless water heater repair professionals will inspect the unit to diagnose any existing issues and fix them promptly. Do not allow frustrations to get better for you. Call My Professional Plumber today to schedule an appointment.

Water Heater Repair: Common Problems With A Tankless Water Heater | Knoxville, TN

What water heater have you installed at your Knoxville, TN, home? From conventional water heaters, hybrid water heaters, heat pump water heaters, and solar-powered water heaters to tankless water heaters, there are many water heater variants that you can rely on for heated water. However, a tankless water heater is the most energy-efficient of all. It heats water on demand, meaning it only uses energy when necessary. Since the water heater doesn’t feature a tank, it also saves you space

However, regardless of how convenient and advanced they are, tankless water heaters aren’t immune to various problems. They also experience normal wear and tear, especially with aging. No electrical appliance doesn’t experience various issues and faults in its lifetime. However, tankless heaters have their issues, unlike conventional water heaters. However, you can put the issues at bay with routine maintenance and inspections by a water heater repair technician.

Tankless water heaters are remarkable for their energy efficiency, space-saving, and water conservation.   All these features can only mean one thing; saving money in the long run. However, various tankless water heater issues might sometimes undermine these benefits. Hence you must understand the most common issues that affect tankless water heaters and take the measures to avert them by enlisting the help of a water heater repair professional. Below are some of the common problems that befall a tankless water heater;


Each tankless water heater usually has a defined flow rate capacity. This should give you a great idea of how much-heated water the unit can produce within a given duration. Further, this can form a great pointer to the number of outlets that can be opened simultaneously. Going over the tankless water heater’s flow capacity could mean that you are overloading the system.

This can cause various issues that might prompt a need for water heater repair. Overloading the tankless water heater is a common problem, especially if you have a young family or guests coming over. Unfortunately, some homeowners don’t realize that there are limitations to the number of simultaneous hot water outlets when it comes to a tankless water heater.

When a tankless water heater gets overloaded, you may notice that some people at your home aren’t getting enough heated water while others are enjoying their showers and hot baths. The water heater might sometimes entirely shut down because of a system overload. Understanding the rated flow capacity of a tankless water heater is the only way to ensure that you don’t overload the unit.

Hence, please read the manual with the tankless water heater to understand its capacity and the number of appliances that can simultaneously draw hot water from the unit. If this issue becomes persistent, then it is best to call a water heater repair professional to inspect your water heater. The water heater might be too small to cater to your family’s needs. In that case, the technician will recommend upgrading it or installing a tankless water heater to compensate for the deficit.

Ignition or Flame Failure

Does your tankless water heater sufficiently heat the water? If it doesn’t, the reason may be that the flame doesn’t hold or even ignite. A gas line or electrical issue may cause this. Regardless you’ll need to enlist the help of a water heater repair technician because the water heater will not be able to heat your water. The professional will begin by checking whether the propane tank has enough gas or if you have a gas supply. If you haven’t paid the bill, your gas utility provider might cut the supply to your Knoxville, TN, home.

If the professional ascertains that the gas supply is alright, the technician will check to see that the gas and water valves are fully open. If they aren’t, the professional opens them fully to allow a complete gas flow into the water heater. If all these are in vain, the water heater repair professional will inspect other parts such as regulators for failure and the undersized gas lines that might pose a risk at your home.

Cold Water Sandwich

Have you ever heard of the cold-water sandwich? If your home has frequent back-to-back showers, then it is most likely that you might have experienced the sensation. Cold water sandwich refers to the phenomenon in which when a person is done showering, and another one enters the shower immediately; they get hot water immediately though for a few seconds. They then experience a cold shower for a few seconds as the water heats up in the pipes, and later, hot water begins to flow.

So, why does this happen? It arises since the water in a tankless water heater doesn’t get heated when no outlet is open. However, there is some hot water that remains in the pipes. The heated water flows for the first few seconds, followed by the incoming cold water. It is at this time when the tankless water heater works to heat the water that you will later receive from a hot water faucet or shower. However, this shouldn’t take too long.

Since this effect is a part of the tankless water heater design, it isn’t too much of an issue. Although a tankless water heater is at times like for the rate at which it heats the water, being that the heated water isn’t stored makes it pretty much impossible for your tankless water heater to deliver heated water immediately. If the cold spells last for long, you should have a water heater repair technician inspect the tankless water heater. There might be other underlying issues.

Sediment or Mineral Buildup

The piping and water heater may become susceptible to partial or complete blockage caused by an accumulation of minerals or sediments. Plumbing systems with iron components and pipes might start rusting, resulting in a buildup of iron sediments. Additionally, if your Knoxville, TN, home receives hard water from your water utility provider, you might see minerals such as magnesium and calcium result in limescale buildup.

The sediments and minerals may become stuck in place, resulting in a gradual buildup. The accumulation narrows the passage through which the water passes. This might affect the water temperature and pressure, making it potentially unsafe. A water heater repair professional can flush the water heater to remove the sediments.

Reputable Plumbing Professionals

Have you experienced either of the above issues with your tankless water heater? Ensure that they are assessed by a professional to ensure that the unit delivers heated water into your home. Do you need a water heater repair service for your tankless unit? Call our technicians at My Professional Plumber.

How Long Do Water Heaters Last? | Tips from Your Knoxville, TN Water Heater Repair Service Provider

Photo By Jo Ann Snover at Shutterstock

Whether you’re washing your hands, taking a shower or cleaning dishes in the sink, you need access to hot water throughout your Knoxville, TN home. Unfortunately, you can’t get that hot water if you don’t have a water heater that’s in good shape. Water heaters aren’t made to last forever, especially without proper water heater repair and maintenance every once in a while. If you’ve got an older water heater or a lack of hot water in your home, here’s what you need to know about how long a water heater is expected to last and what you can do to help that.

Water Heater Life Expectancy

Most of the fixtures and appliances in your Knoxville, TN, home have somewhat of a life expectancy; while they can last longer than this life expectancy, they don’t in the majority of cases. This is an important thing to keep in mind when it comes to how often you should replace the fixtures in your home.

While repair can extend the life of a water heater by a bit, the average life expectancy of a water heater is about 8 to 12 years. You can find an exact recommendation from your water heater manufacturer, but if you’ve got a water heater that’s 12 or 15 years old, now is a good time to replace it.

Another thing to keep in mind when it comes to water heater life expectancy is that it depends on the location of your unit, the frequency of water heater repairs and maintenance and the water quality in your home. Ultimately, the number you get from your manufacturer is more of a general guideline.

Types of Water Heaters

One important thing to remember in terms of how long your water heater is expected to last is that it depends on the type of water heater you have. Tank-type water heaters have the shortest lifespan because they’re constantly full of water that can eventually cause corrosion in the tank.

A lot of Knoxville, TN homeowners are opting for tankless water heaters these days because of the convenience and longevity they provide. Since tankless water heaters aren’t constantly holding a tank full of water, they can last as long as 20 years depending on the manufacturer and model. This is a great solution if you’re looking for a water heater upgrade that will last a bit longer than a traditional water heater.

If you do opt for a tankless water heater, you should know that water heater repairs and maintenance aren’t quite as simple. Tankless water heaters are a bit more advanced than traditional tank-type heaters, which means you need to find a plumber who knows what they’re doing if you expect to fix your tankless water heater instead of replacing it.

Water Heater Maintenance

As is the case with most things in life, taking care of your water heater is the best way to ensure it lasts a long time. As a general rule, you should have your water heater maintained by a professional at least once every six months, although you may need to do it more often depending on your water quality.

The biggest thing you can do to avoid hefty repair bills is flush your tank on a somewhat regular basis. Most homeowners can get away with flushing their water heater once every six months or so, but you may have to do it more frequently if you’ve got particularly hard water.

Hard water is water that has a lot of minerals in it, which can cause a mineral buildup in appliances and fixtures throughout your home. If you’ve got a big problem with hard water that’s shortening the life of your fixtures, the best thing you can do is invest in a water softener. You can get a water softening system for your entire Knoxville, TN, home that removes minerals from your water and makes it easier on fixtures. This may be a smart investment when compared to the cost of water heater repair and spending thousands to replace fixtures and appliances prematurely.

Is Water Heater Repair Worth It?

If you read about how long your water heater should last, you’ll notice that a lot of articles talk purely about water heater replacement and not repairs. While there are water heater repairs that can extend the life of your water heater by quite a bit, the fact of the matter is those repairs can only keep it running for so long.

Water heaters are equipped with a sacrificial anode that’s designed to take the brunt of the corrosion caused by the water in your tank. If there weren’t a sacrificial anode, the tank would quickly corrode and you’d have to replace the whole water heater. In fact, that’s the problem with water heater repair; you can replace the sacrificial anode and the elements in your water heater for years, but the tank is only going to last so long before corroding. And the fact of the matter is, replacing your water heater is the only way to reliably fix a busted tank.

Before you spend money to have your water heater repaired, have a professional take a closer look at things to make sure replacement isn’t a better option for you.

Simple Service

No matter what fixture or appliance you’re dealing with, the fact of the matter is things don’t last forever. The best thing you can do to avoid paying for expensive repair bills is keep up with routine maintenance and fix problems as needed.

Having a good plumber on your side is a big help when it comes to taking care of your water heater, and My Professional Plumber of Knoxville, TN has you covered. Not only can we help with water heater repair and maintenance, we can replace your water heater for you if that’s what you need. Give us a call at (865) 622-4101 to schedule an appointment today.

How a Tankless Water Heater Works and the Benefits It Offers | Plumber in Knoxville, TN

Also known as on-demand water heaters, a tankless water heater stays true to its namesake as it does not need a storage tank to work. This is great news for homeowners who are tired of calling a plumber in Knoxville, TN to fix leaks in their existing tanks.

How It Works

To understand how this tank works, you need to understand how the traditional tank heater operates. This system works by heating water in a large tank which has to be heated continuously to a constant temperature so that you can have hot water when you need it. However, since the tank needs to generate heat continuously even when the hot water is not being used, a lot of that energy is wasted.

Tankless water heaters are designed to avoid this issue like any plumber in Knoxville, TN will tell you. These only heat water that fills the tank and only when that hot water is needed. This is why they are also known as ‘on-demand’ heaters.

A powerful heat exchanger in the tankless water heater raises the temperature of the water to piping hot when needed. It works by transferring energy from one source to the other similar to how it works in a refrigerator and in your car radiator.

In a water heater, the exchanger works by transferring the heat that is produced by heated coils or a gas burner to the water that is directed towards a faucet or shower. It does this only when it detects incoming water flow and heats it to a preset temperature.

Types of Tankless Water Heaters

As a plumber in Knoxville, TN will tell you there are basically 2 types of tankless water heaters based on their size. The small one, for instance, is usually installed by people who live in small units such as an apartment while the larger ones are meant to serve an entire household.

While you can hire a plumber in Knoxville, TN to install multiple small tankless water heaters in your home to save money, you should just get a bigger one to save yourself the trouble. Depending on the size of your home and the number of people living in it, you may have to get more than one large unit. These can provide hot water to several points-of-use or locations in the house. To get the most out of the water heater, you should get it insulated by a reliable plumber in Knoxville, TN.

Benefits of Tankless Water Heaters

No more cold showers– Nothing is more scream-inducing than chilly water landing on shivering skin. If you live with family members, chances are this has happened to you more times than you can count. Rather than yelling at them to stop hogging the hot water, get a tankless water heater installed by a plumber in Knoxville, TN. Since it does not depend on a reserve of hot water and just heats water as it is needed, you can look forward to a warm shower every morning.

High Distribution Rate– Since tankless water heaters heat water as and when it is needed, you can do a lot of things simultaneously while using it. For example, even if someone is taking a shower you can run the dishwasher, washing machine and even use another shower in the house at the same time without running out of hot water. The tank will not stop producing hot water and will not run out of it either.

Last longer– These water heaters can make sure that you receive hot water when needed for at least 10 or at most 15 years. Traditional water heaters, on the other hand, can only last for 6 to 10 years at most.

Conserves water – plumber in Knoxville, TN will tell you that a simple water heater can take a couple of minutes to produce hot water but it will take almost half an hour to refill the tank. Tankless ones, on the other hand, do this instantly since it heats flowing water. This saves a lot of time and water which would otherwise go down the drain unused while you wait for a traditional heating unit to do its job.

Saves money – Since tankless water heaters run way more efficiently than their traditional counterparts and use less energy as well, that translates to more money in your pocket. In fact, an average unit can save about 30% of energy on a yearly basis.

Saves space– A tankless unit is about one fifth the size of a traditional one so it can be mounted pretty much on any wall that is close to the plumbing. Since they are also safer to use in comparison, they can be placed in areas where a traditional unit may prove dangerous.

Clean water – As a plumber in Knoxville, TN will tell you when the water in a traditional heater cools down, it remains in the tank. This makes the tank rust which can contaminate the water you use the next time you need to wash your clothes or need a bath. Since tankless water heaters don’t have a tank and only heat water as it flows through, you get clean water to bathe in, drink and use for ablutions.
