Tank Water Heater vs Tankless Water Heater The Pros & Cons - Lake Cook Plumbing

Water heaters are essential home appliances that provide hot water for various purposes like washing dishes, taking showers, and doing laundry. If you are planning to install a new water heater or replace your old one, you may have come across the two main types of water heaters available in the market: tank water heaters and tankless water heaters.

In this article, we will discuss the pros and cons of tank water heaters and tankless water heaters to help you make an informed decision based on your needs and budget.

Tank Water Heater vs. Tankless Water Heater: Which is Better?

Tank water heaters, as the name suggests, have a large tank that stores and heats the water. The water is heated continuously to maintain a steady supply of hot water. On the other hand, tankless water heaters heat water on demand, which means that they do not have a storage tank, but instead heat water as it flows through the unit.

Both types of water heaters have their pros and cons. Tank water heaters are more affordable to purchase and install, but they are less energy-efficient, as they continuously heat and maintain a large volume of water. On the other hand, tankless water heaters are more energy-efficient and provide an endless supply of hot water, but they are more expensive to purchase and install.

Pros and Cons of Tank Water Heaters


  • Lower upfront cost: Tank water heaters are generally cheaper to purchase and install than tankless water heaters.
  • Simpler installation: Tank water heaters are easier to install and require less specialized equipment and expertise.
  • Availability: Tank water heaters are widely available and can be found in most hardware stores and plumbing supply stores.


  • Less energy-efficient: Tank water heaters continuously heat and maintain a large volume of water, which is less energy-efficient.
  • Limited supply of hot water: Tank water heaters have a limited supply of hot water, which can be a problem for large families or households with high hot water usage.
  • More space required: Tank water heaters require more space for installation and may not be suitable for small homes or apartments.

Pros and Cons of Tankless Water Heaters


  • Energy-efficient: Tankless water heaters are more energy-efficient than tank water heaters, as they only heat water as it is needed.
  • Endless supply of hot water: Tankless water heaters provide an endless supply of hot water, which is suitable for large families or households with high hot water usage.
  • Space-saving: Tankless water heaters are smaller in size and take up less space than tank water heaters.


  • Higher upfront cost: Tankless water heaters are generally more expensive to purchase and install than tank water heaters.
  • Complex installation: Tankless water heaters require more specialized equipment and expertise for installation.
  • Maintenance costs: Tankless water heaters require regular maintenance to prevent mineral buildup and ensure optimal performance.

Which Water Heater is Right for You

When it comes to choosing between a tank and tankless water heater, there are several factors to consider, including:

  • Your budget: Tank water heaters are generally more affordable upfront, while tankless water heaters may cost more but can save you money on energy bills in the long run.
  • Your hot water needs: Tank water heaters have a limited supply of hot water, while tankless water heaters can provide an endless supply. Consider your household’s hot water usage to determine which option is best for you.
  • Available space: Tankless water heaters are more space-saving than tank water heaters, so if you have limited space in your home, a tankless option may be a better choice.
  • Installation complexity: Tankless water heaters require more specialized equipment and expertise for installation, so if you are not comfortable with complex installations, a tank water heater may be a better option for you.

By considering these factors and weighing the pros and cons of each type of water heater, you can choose a replacement water heater that is right for your home and budget. And, if you need further assistance, don’t hesitate to contact a plumbing professional for advice and installation.

Water Heater Replacement Cost Comparison

In addition to understanding the pros and cons of tank and tankless water heaters, it’s also important to consider the cost of replacing your existing water heater with a new one. Here’s a cost comparison of both types:

As you can see, tankless water heaters have a higher initial and installation cost, but they are more energy-efficient and have a longer lifespan compared to tank water heaters. However, if you have a limited budget and don’t want to spend too much money upfront, a tank water heater may be a better option for you.

Ultimately, the cost of replacement will depend on a variety of factors, such as the type and size of water heater, the complexity of the installation, and your location. It’s always a good idea to get quotes from multiple plumbing professionals to ensure you are getting a fair price.

Both tank water heaters and tankless water heaters have their pros and cons. The choice between the two depends on your needs, budget, and available space. If you need help with water heater repair, contact Lake Cook Plumbing for further assistance.

Choose A Replacement Water Heater That’s Right For You

Overall, understanding the differences between tank water heaters and tankless water heaters can help you make an informed decision when it comes to choosing the right water heater for your home. By considering the pros and cons of each type and taking into account your household’s specific needs, you can select a water heater that will provide you with reliable, efficient hot water for years to come.

In summary, if you are in the market for a new water heater or need water heater repair, take the time to consider your options and consult with Lake Cok Plumbing to ensure you make the best decision for your home and budget.

High-Efficiency Water Heater Worth It? | For Lake County Homes

  • Water Heaters
High-Efficiency Water Heaters worth it for Lake County

Are you looking for ways to save money on your home’s energy bills? Investing in a high-efficiency water heater may be a smart decision for you. Although the cost is a bit higher initially, the savings may make investing in a high-efficiency water heater worth it in the long run. With so many options available on the market, it can be overwhelming to choose the best water heater for your Lake County home. In this blog, we will explore the advantages of investing in a high-efficiency water heater and help you make an informed decision.

Advantages of Tankless vs. Tank Water Heater Efficiency

Tankless water heaters are more efficient than tank water heaters because they only heat water when you need it. With a tank water heater, the water is constantly heated and stored in the tank, which can lead to energy waste. On the other hand, a tankless water heater only heats water on demand, saving you money on energy bills.

Do Tankless Water Heaters Save Enough Money to be Worth It?

Yes, tankless water heaters save money in the long run. While they may have a higher initial cost than tank water heaters, they have a longer lifespan and require less maintenance. Tankless water heaters are also more energy-efficient, which can save you money on your monthly energy bills.

Gas vs. Electric Water Heater Efficiency

High-efficiency water heaters are capable of using up to 50% less energy compared to standard water heaters, resulting in significant energy savings for homeowners. For many people, this fact alone makes investing in a high-efficiency water heater worth it. When choosing between a gas or electric water heater, it’s important to consider the efficiency of both options. While gas water heaters are typically more efficient, heating water faster and requiring less energy to do so, electric water heaters are more environmentally friendly and may be a better option for those who do not have access to natural gas. However, it’s worth noting that high-efficiency electric water heaters are also available and can offer significant energy savings compared to standard electric water heaters. Ultimately, the choice between gas and electric water heaters will depend on your specific needs and preferences.

Most Efficient Water Heater Brands

There are many high-efficiency water heater brands on the market, but some stand out above the rest. Rheem, Bradford White, and A.O. Smith are all known for their energy-efficient water heaters. Additionally, hybrid water heaters are becoming increasingly popular due to their energy efficiency and versatility.

In conclusion, investing in a high-efficiency water heater for your Lake County home is worth it. Tankless water heaters are more efficient than tank water heaters, gas water heaters are typically more efficient than electric water heaters, and there are many efficient water heater brands to choose from. By choosing a high-efficiency water heater, you can save money on your energy bills and do your part to protect the environment. If you’re looking into getting a new water heater, our technicians can help you choose and install the water heater that works well for you and your home.

Common Plumbing Problems You May Encounter Before Winter Ends 

Common Plumbing Problems You May Encounter Before Winter Ends 

  • Plumbing
winter plumbing problems

Winter is in full swing here in Lake, Cook, and McHenry County and there are plenty of issues that can arise with your home’s plumbing if you’re not careful. From frozen pipes to water heater issues, no one wants to have a plumbing problem when the temperature is freezing. Make sure you avoid winter plumbing problems with scheduled service from Lake Cook Plumbing!

Frozen and Burst Pipes

When the temperature drops in Lake County and the surrounding area, the chance of your pipes freezing goes up. Anytime the temperature drops below freezing for an extended period of time, you are at risk of pipes freezing, too.

The pipes in the most danger are those in basements and attics. These spaces are typically less insulated than other rooms in your home and can freeze more easily. These spaces are also the least visible in your home, so you may not notice the frozen pipe immediately. 

A frozen pipe left alone can easily turn into a burst pipe. A burst pipe causes flooding damage and loss of water to parts of your home. In order to prevent these problems, it is critical to have a functioning heating system. This is your first defense to frozen pipes. Insulating those exposed areas, such as attics and basements, will reduce the chance of frozen pipes along with a warm home. 

If your pipes do freeze- don’t panic. Your local technicians at Lake Cook Plumbing are here to help. We can assist with repairing your burst pipes. 

Water Line Leaks

If you’ve had small water leaks in the past, leaving them to get worse during the winter can spell disaster. The freezing temperatures put strain on pipes and can turn a small leak into a burst water line. Before the cold weather sets in, you should inspect any faucets and pipes in your home for leaks. Calling a local plumber from Lake Cook Plumbing will ensure that your home will stay dry and damage-free  this winter. 

Water Heater Issues 

Imagine waking up on a cold morning, ready to take a relaxing, hot shower- only to find upon entering it that your water heater isn’t working. 

A water heater malfunction during the coldest months of year is the last thing you and your family need. However, if you have an older model or have not maintained the current unit, a breakdown may be just around the corner. 

It is crucial to have your water heater regularly serviced in order to prevent early heater breakdown. If your model is more than 10-12 years old, it’s probably time to get a full replacement. Call a professional technician at Lake Cook Plumbing today to schedule your water heater replacement! 

Clogged Drains

The winter months bring increased demand onto your drains and pipes. When food particles and grease enter your pipes, they can stick to the side of your pipes and block drainage. In the winter the colder temperatures may stiffen grease and food particles making them more likely to block water flow to drains.

This kitchen problem is in addition to the shower and bath with increased hair and soap scum flowing down your drains. The last thing you want is clogged drains with a full house. If you notice any of your pipes becoming slow to drain, call Lake Cook Plumbing to help you out before a full blown clog forms. Once a clog forms, it becomes a much larger job to fix than a partial blockage. Let us help you sail through winter with no issues!

Winter Guide to Gas Hot Water Heater Maintenance

The winter season is almost here, which means it’s time to prepare your home for the snow and frigid temperatures. You’ve insulated your plumbing, cleared your gutters, and prepped the standby generator, but there’s one appliance you can’t forget. Just like the furnace, homeowners will rely on their gas water heater during the winter season, but your gas water heater is just as strained from use due to the drop in temperature. Proper maintenance for your gas water heater not only ensures you can enjoy heated water throughout the holiday season, it prevents a plumbing catastrophe. Check out our winter guide to gas hot water heater maintenance.

How You Can Prepare Your Gas Water Heater this Winter

A damaged gas water heater poses a lot of problems beyond the frustration of a lack of hot water. Over time and use, your gas water heater can wear down, especially for homes that run on hard water. Pipes can rust and contaminate your drinking and bathing water, a leak can cause costly water damage, and even worse, your gas water heater tank can explode. Luckily with proper maintenance, you can enjoy your heated water without a plumbing catastrophe. Here’s how you can stay warm and dry this winter season.

  • Flush your gas water heater. Your water heater works the hardest during the winter season, and over time mineral deposits can settle at the bottom of the tank and break down the water heater. Mineral deposits prevent your gas water heater from operating efficiently and it can clog your water lines. That’s why it’s important to flush your gas water heater at least twice a year to clean out the mineral deposits.
  • Check the pressure valve. Your gas water heater has a pressure valve called the TPR valve that releases pressure whenever the tank becomes over pressured. To test your TPR valve, life the trip lever on the valve and release it again. You should see some water exit or hear a faint hint of air exiting the valve. If you don’t see anything exit the valve or water just keeps flowing out, you might need to replace the TPR valve. It’s a good idea to check your gas water heater’s pressure valve every six months to check for clogs or leaks.
  • Check the filters. Some gas water heaters have a filter to catch any problematic debris. Your water heater works best when it’s clear and clean of sediment and debris, which is why it’s important to routinely clean or replace your filters if your gas water heater has one.
  • Inspect the thermostat. Some heating problems aren’t caused by the appliances themselves, but a malfunctioning thermostat. A functional thermostat is important for all your heating appliances, as it prevents your gas water heater from overworking itself to keep up with inconsistent temperature settings.
  • Check the anode rod. The anode rod is another important component of your gas water heater that works to capture any corrosive material in the water. Your gas water heater tank is susceptible to rust and corrosion, which is why it’s important to occasionally check the anode rod. Watch for any calcium deposits, missing parts, or if the rod itself has dissolved to less than half inch thick. Anode rods can last up to 5-10 years, but they can last longer if routinely cleaned.
  • Adjust the temperature. The winter season makes it difficult to be energy efficient, especially when you heavily rely on your heating appliances. Adjusting the temperature setting on your gas water heater, however, can save in energy costs and prevents your gas water heater from overheating.
  • Insulate your tank and pipes. Just like the rest of your plumbing this winter season, a little insulation can go a long way. Covering the tank and attached pipes with an insulated material can help to keep the hot water in the pipes warmer for an extended period of time.
  • Clean out air intake and exhaust vents. Like your furnace, your gas water heater needs proper ventilation in order to function. Snow is a common issue for your gas water heater’s air intake and exhaust vents during the winter season. Snow and other debris can clog inside the vents and cause damages to your gas water heater. Fencing off snow and installing a metal mesh to keep pests out helps to keep your vents clear and water heater running efficiently.

Stay Warm this Winter by Taking Care of Your Gas Water Heater

A home with a damaged gas water heater makes for a miserable holiday season. A poorly maintained gas water heater is more than a nuisance, but a costly plumbing problem. Luckily you can stay warm and dry thing winter with routine maintenance. Proper maintenance however, can only help so much; sometimes you’ll need professional help. A licensed plumber can help guarantee your gas water heater is fully functional and prepared for the incoming winter season. Don’t wait until there’s water in the basement, call a plumber today.

Now that you’ve read our winter guide to gas water heater maintenance, what do you do next?

3 Amazing Benefits of Water Heater Repair in Lake Zurich

3 Amazing Benefits of Water Heater Repair in Lake Zurich

  • Water Heaters

Your home’s water heater is one of those out-of-sight, out-of-mind appliances. When it’s doing its job, it barely gets noticed. When it’s on the blink, nothing gets more attention. Lukewarm showers can be a thing of your past. If you need a water heater repair in Lake Zurich, Lake Cook Plumbing is the place to call.

New Water Heater Replacement Saves Energy

The energy efficiency of newer water heaters saves money on your monthly energy bill and quarterly water bill.  These savings add up on an annual basis and eventually your water heater will pay for itself. Older water heaters are not lined as efficiently as newer models which affects water temperatures inside the tank. It also affects the length of time your water heater can keep your water heated. So, while your old water heater might seem to be working well, a new water heater replacement can ensure a consistent supply of hot water at a lower cost.

New Water Heater Replacement Saves Money

New energy efficiencies, less water waste and lower water cooler cost makes a new water heater a good investment. New and efficient water heaters can even increase the value of your Lake Zurich home. You’ll you save money in the long run on energy costs. Plus, you’ll save money immediately by eliminating costly repairs to your old unit.

New Water Heater Replacement Saves Water

When replacing your water heater, consider the new tankless models. They provide water on demand. This means no more 40+ gallon tanks of hot water eating up floor space and storing already heated water. These water heaters have many benefits. They are a lot less expensive to operate as they only heat the water as needed. These nifty new heaters have a much smaller footprint and are more likely to increase the value of your home.

5 Signs You Need Water Heater Replacement

5 Signs You Need Water Heater Replacement

  • Plumbing
  • Water Heaters
water heater replacement in Illinois by Lake Cook Plumbing

Appliances like your water heater won’t work forever, and you’ll eventually need to order a replacement. Preferably, you’d like to get a water heater replacement before your current one breaks and floods your home. If you keep an eye out, you can notice signs that your water heater may soon need replacing. At Lake Cook Plumbing, our professionals can help you learn the signs so you’ll know when you need a water heater replacement for your home.

Here are five signs you should call us to arrange a water heater replacement for your home:



Leaks are a common problem with older or damaged water heaters, but you might not notice the leaks if you don’t keep an eye on your water heater. When searching for leaks, check the fittings, connections, and temperature-pressure-release valve. If one of those happens to be leaking, they can be fixed fairly easily. However, if the leak is caused by damage to the tank, you’ll need to get a new tank as soon as you can.


Rusty water

Is your home’s water looking and tasting rusty? There are two possible causes, and you can determine the cause by looking at what kind of water is rusty. If only your hot water is rusty, the rust is likely coming from a damaged water heater. However, if both temperatures are producing rust, the problem is with a pipe in your plumbing. Either way, you’ll want to immediately call for one of our technicians to prevent any major damage. You’ll often see rust around the water inlet or pressure release valve if the tank is rusting. To confirm your water heater’s rust problem, drain a few buckets of hot water from the tank. If you’re still getting rust by the third bucket, then you’ll need a new water heater.


Old age

Unlike fine wine, your water heater doesn’t get better with age. A well-maintained tank water heater can last around ten to fifteen years. This means you should consider a replacement when it gets nine or ten years old. Don’t know when yours was installed? Check the water heater’s serial number and look at the manufacturer’s information.  The serial number can tell you when it was manufactured, but each manufacturer has a different way of displaying the manufacturing date. The manufacturer’s website might be able to help you, but be prepared to do a bit of research.


Strange noises

Major appliances always make a bit of noise when they’re working, but that’s nothing to worry about. However, loud popping, cracking, or rumbling noises mean you should call us because sediment build-up in the tank is making it hard for the unit to run. As tank water heaters operate, sediment can build up at the bottom of the tank, and will eventually harden as it heats and cools. Not only do the heater air pockets make noise,  but the sediment can make your water heater less efficient and make it more likely to crack. If not fixed with flushing and cleaning, the tank can become damaged and start leaking. When your tank starts leaking, the only thing you can do is replace it.


Not enough hot water

Unsurprisingly, your water heater heats your home’s water. When you’re not getting hot water despite having the proper temperature settings, there’s a problem. There are many reasons you’re not getting the right temperature, and a couple are unique to different types of water heaters. Gas water heaters might require you to relight the pilot light while electric models might necessitate a trip to the circuit breaker. Very cold weather also can freeze up your pipes and tank if they aren’t insulated enough. However, if none of those are the problem, you might be dealing with a faulty thermostat, worn heating element, or a build-up of sediment. It’s also possible your water heater isn’t big enough for your home’s hot water demands. In that case, call us up and we can help you find one that’ll work best for your home.
