Water Heaters (Tank vs. Tankless)

Despite being an essential part of the home, a water heater rarely gets the attention it deserves. Let’s admit many of us forget how to operate a water heater at home. Though it is a workhorse that runs every day through all seasons, delivering warm water to sinks and showers, we rarely think about its maintenance.

When you can’t get hot water, or the heater takes longer to warm the water, it’s a sign that you should consider buying a new one. You may consult professional plumbing services like Conejo Valley Home Services Plumbing & Rooter to check your water heater and help you make the right decision.

If you decide to invest in a new water heater, the first thing to decide is whether you should buy a tank or tankless water heater. If energy efficiency is one of your concerns, you should spend more time deciding on a specific option.

If you’re the type to decide based on current trends, the chances are that you’ll opt for a tankless water heater. The new technology claims to use less energy compared to storage water heaters. But are these heaters more energy efficient? What is their operational cost, or do they offset the high upfront expenses?

If you’re considering buying a water heater, keep on reading to learn more about their types and the differences between them.

Water Heater Repair, Maintenance, and Installation

When a water heater stops working, it may mean no more high-temp laundry cycles, hot dishwashers, or warm showers. It is always better to hire qualified plumbing professionals as your comfort means everything for them. Whether you require assistance in installing, repairing, or replacing your water heater, competent professionals like Conejo Valley Home Services Plumbing & Rooter are always willing to help you.

A tank-type water heater is easier to install and maintain. A tankless water heater, on the other hand, saves money and lasts longer. Plus, it’s cheaper to purchase tankless water heater parts as opposed to those of a tank-type water heater.  

Your previous tank type is also an important consideration when installing a tankless system. Keep in mind that the installation cost of a tankless water heater in a business and home (that previously had a tank-type water heater) is usually higher. It happens because the local plumbing contractor needs to retrofit the entire system to install a tankless heater and ensure proper functioning. 

Types of Water Heaters


What is a Tank Water Heater?

The tank water heater is the most common type of water heater found in homes. Typically, it is a conventional model comprising an insulated tank that heats and stores water. It comes with an attached pipe on the top that pulls the water when you need it. The water heaters, in general, run on fuel or natural gas. Also, these tanks use less energy compared to electric water heaters.

How Do Tank Water Heaters Work?

A tank-type water heater increases the temperature of the water supply using either of two modalities: fuel or electricity. If you have a fuel-powered water heater, it may be powered by either oil or natural gas. 

Many homeowners opt for water heaters that use natural gas. Oil-based water heaters are also a popular choice in specific geographical areas.

Generally, a tank-type water heater:

A home inspection was done for the sale of our home and the inspector flagged our furnace as not having a furnace door switch and being a potential fire hazard. Parker arrived to open the furnace door to find that the switch had a piece of black tape over it to protect it, he removed said tape, job done. Unreal. Thanks Parker.

Gave us an estimate and we decided to wait a few months before booking. I called when we were ready to book, but the person they directed us to never called us back!We ended up choosing another local plumber who charged half what CVHAPR quoted us. I'm so glad we got a second opinion.

Conejo Valley replaced our A/C and furnace in 2014, and just replaced our 20 year old tank water heater today. We switched from tank to tankless and were very impressed with the work. The technicians were very knowledgeable and organized; for us, the installation took only 3 hours as the space was pretty easy to access. I highly recommend Conejo Valley! The office called as soon as they left to check on how the installation went. Great customer service. To the technicians, thanks for your hard work!

Exceptional service from making an appointment with Nancy to Nick repairing leak under kitchen sink. Extremely professional, arrived on time, wear booties (not necessary for me), offered to wear a mask, respectful and neat. Reasonable fair pricing which turned out to be nothing major. I will use them again if needed. Thank you.

Art did an excellent job. He stayed late on a rainy day to ensure my drain was working. He talked me thru the entire process and took the extra time to locate the issue and fix it as best he could. He got our drain working and gave us the long term solution and cost. I’d definitely use this company and specifically Art again.
How Long Do Tank Water Heaters Last?

It is essential to know the right time to replace a water heater before it causes inconvenience or springs leaks. Failing to get timely repairs raises the risk of leaks damaging your home. Typically, a tank water heater lasts 6 to 12 years. After 12 years, you’re on borrowed time.  

Beyond this period, various factors can affect the longevity of a tank water heater. Such factors include the type of water running, your yearly schedule to drain and flush the tank, and how much water you use.

Advantages of a Tank Water Heater

Although they are older technology, storage water heaters have some advantages over the newer models.

While tankless water heaters are a suitable option for many homes, they are not ideal for all of them. There are cases when sticking to the familiar options like traditional tank water heaters are better. Though using older technology, they offer some advantages over advanced models.

Disadvantages of a Tank Water Heater


What is a Tankless Water Heater?

A tankless water heater is a newer option that can provide hot water when homeowners need it. Typically, tankless water heaters don’t have excess cost or outlay of standby operations like traditional storage water heaters.

Tankless heaters use gas or electricity to supply water via a pipe attached to the machine. With tankless water, there is no need to stock up hot water.

How do Tankless Water Heaters Work?

As described above, there is no need to store hot water in a tankless water heater, allowing you to save a lot of space. Note that a tankless water heater only starts heating up water when the faucet turns on.

Turning on the tap triggers the flow rate sensor to pass water through. This means it only heats up water on demand to save on energy. Speaking of which, you can run a tankless water heater with gas or electricity.

How Long Do Tankless Water Heaters Last?

A high-quality tankless water heater lasts twenty years, especially if you purchase one from a reliable manufacturer.

How to Know When You Need a New Water Heater

Things to Consider When Buying a Water Heater

Regardless of your reason for purchasing a new water heater, you need to consider certain factors to reap its benefits in the long run. Here are some of them you should take into account:  


A tank heater typically holds around 50 to 60 gallons of water. Considering a water heater’s capacity is essential because it often comes in different sizes. Plus, it depends on the number of people who use water in the house. The maximum water usage in the house is another important aspect you must consider when assessing capacity.

Many water heaters come with an hour rating system that calculates how many gallons a heater produces in an hour.

Type of Water Heater

You can choose from plenty of water heater types. However, make sure you choose a water heater that fits your usage needs. Some water heater types are:

Fuel Type

You can rely on different energy sources to run your water heater. These include solar, gas, geothermal, and electricity. Choose one that suits your needs the best. 

How Long Does it Take to Replace a Water Heater?

The average amount of time it takes to install a tank, whether electric or gas, takes no more than 2 to 3 hours. It may take 40 to 60 minutes to disconnect, drain, and remove the old water heater.

Which Water Heater is Right for You?

Though conventional water heaters have their benefits, they are less efficient than tankless heaters. Plus, they have higher operating and maintenance costs. Tankless water heaters may have higher installation costs, are more energy-efficient, and reduce heating costs significantly.

Average Cost of Water Heater Replacement

Depending on the choice, the average cost for replacing a water heater is between $1,000 and $35,000. The cost may also vary depending on the state you live in. Make sure you discuss the cost of water heater replacement with your plumbing professional before hiring them.
