Pros and Cons of Getting a Tankless Water Heater Installed

Tankless Water Heater Installation

Are you tired of waiting for hot water every time you turn on the tap? Are you also looking to upgrade your water heating system to something better and more efficient? If so, you should consider a tankless water heater. In recent years, tankless water heaters have become popular for their energy-saving benefits and on-demand hot water features. However, like any home improvement, installing a tankless water heater has both advantages and disadvantages. In this blog post, let’s talk about all the pros and cons of getting a tankless water heater installed in your home.


Understanding Tankless Water Heaters

Have you ever wondered how tankless water heaters work and what makes them different from old and traditional tank water heaters? Well, let us share some interesting facts with you. Tankless water heaters, whether electric or gas tankless water heaters, unlike traditional ones, don’t store hot water in a big tank. Instead, they heat water on demand, giving you an endless supply of hot water whenever needed. This happens when cold water passes through a heat exchanger in the tankless water heater unit, getting heated by an electric element or gas burner. With a tankless water heater, you no longer have to worry about constantly heating a large amount of water in a tank or running out of hot water.


Pros of Getting a Tankless Water Heater Installed

There are numerous benefits to getting a tankless water heater installation, including hot water on demand, a compact design that saves space and energy, and much more. Knowing these pros helps you decide whether a tankless water heater is right for you. Let’s know more.


Hot Water Supply Whenever You Want

With a tankless water heater unit, you can easily access hot water whenever needed. Get a brand new water heater installed by professionals, and say goodbye to running out of hot water during long showers or after multiple family members have used the bathroom. The on-demand nature of tankless heaters ensures an uninterrupted and continuous supply of hot water 24/7.


Space-Saving Design

Did you know that tankless water heaters are great when it comes to space-saving for your home? Not only are they more compact than conventional tank water heaters, but they also reclaim valuable storage space in your utility room. So, if you’re looking for a convenient way to upgrade your home’s heating system, a tankless water heater system is the perfect choice for you!


Best For Energy Efficiency

One of the main benefits of tankless water heaters is their energy efficiency feature. Unlike old and traditional water heaters, which must keep a large amount of water hot at all times, tankless heater systems only heat water when you need it. This means that there is no standby heat loss, which saves energy and lowers your utility bills. 


What’s more? Besides their energy efficiency, tankless water heaters have other benefits. They are compact, take up less space in your home, and also have a longer life than traditional water heater units, which means that you won’t have to replace them as often. Tankless water heater systems are also more reliable since they don’t have a tank that can burst or leak. 


Overall, tankless water heaters are great for anyone who wants to save money and energy. They cost more upfront than traditional water heaters, but the long-term savings are substantial. Plus, their compact size and reliability make them an ideal investment for any residential building, whether a single-family home, condominium (condo), townhouse, apartment, duplex, or triplex.


Reduced risk of water damage

Tankless water heater units offer several benefits compared to water heaters with tanks. One of the biggest advantages is their longer life. While tank systems last around 10-15 years, tankless water heater units last up to 20 years or more, but you have to do regular and proper maintenance.


Longer lifespan

Another advantage is that tankless water heaters don’t store large amounts of water, which reduces the risk of water damage due to corrosion, ruptures, or leaks. This is beneficial for those people who are concerned about potential water damage in their homes.


Government incentives

Many regions offer government incentives and rebates for installing energy-efficient appliances like refrigerators, dishwashers, ovens, microwaves, and tankless water heaters. By taking advantage of these programs, you can offset the initial installation costs and also save money in the long run.


Cons of Getting a Tankless Water Heater Installed

Now that we have told you the amazing cons of tankless water heater installation let’s now learn some cons of getting a tankless water heater, such as higher initial costs, complex installation, and more. These cons will make you well-informed and will make the purchase design easier for you.


Complexity in the installation process

Installing a tankless water heater is more complex than replacing a traditional one. Depending on the type of tankless water heater unit you choose, it requires changes to your home’s electrical system or gas lines. This complexity results in higher installation costs, which you will never want. It is best to contact a professional water heater installation company and discuss your needs with them. They will come up with the right solution for you.


Stay Proactive in Maintaining Tankless Water Heaters

Tankless water heaters need regular maintenance to make sure they are performing at their best. This includes descaling the heat exchanger to prevent mineral buildup. Neglecting routine maintenance leads to decreased efficiency and potentially costly repairs. Always hire a professional and experienced water heater installation company, and make sure you are regularly following the routine maintenance schedule.


The “Cold Water Sandwich Effect”

It’s possible that you feel a sudden burst of cold water while taking a shower, especially after using hot water. This is the “cold water sandwich effect,” and it is uncomfortable for most people. Although it is common in many models, some shower heads are designed to mitigate this problem. It’s worth remembering this while choosing a showerhead for your bathroom.


Limited hot water output

Have you ever experienced a sudden drop in water temperature or pressure while washing dishes or taking a shower? If you have, then you know how uncomfortable and frustrating it can be. Tankless water heaters are great for this problem as they provide hot water on demand. However, you should keep in mind that their output is not limitless. 


If you have multiple faucets or appliances running hot water simultaneously, you may notice a decrease in water pressure or temperature. This limitation is more noticeable in electric tankless water heaters compared to natural gas water heater units. Having information on these topics is always useful because it will help you call the right technician for the problem you are facing. It also saves you time and money, and sometimes, you can fix these problems on your own using DIY methods.


Tankless vs. Traditional: Choosing the Right Hot Water Hero for Your Home!

When it comes to water heaters, there are two primary options to choose from: the more modern tankless system or the traditional tank water heater. While the conventional tank water heater has been around for decades and is still commonly used, modern tankless water heaters are gaining popularity due to their countless advantages. Some of the most notable tankless water heater pros include their compact size, longer lifespan, and energy efficiency. However, some cons are also considered, such as their potential for limited hot water output and higher upfront costs. Ultimately, deciding whether to get a tankless water heater installed will depend on your needs, budget, lifestyle, and other priorities.
