With December gone and January in it’s early beginnings, for those who do not have the luxury of warm temperatures year round, winter is in its prime stages. Snow starts falling, roads become unsafe, and for kids hopefully these occurrences means snow days. For the adults, however, or those who are living by themselves, winter brings with it some problems for many people. Among the extreme colds, constant icy conditions, and dramatic snowfalls, some people will find that their water heaters are either not functioning any longer, or the water is taking way too long to become hot. This can make problems for those wanting to take hot showers, as well as for those who require hot water quickly, instead of boiling it. Winter tries many things, and the durability of your water heater is one of the things that is tried every year. A popular option for many now is the tankless water heater, a water heater that boasts many things, the most prominent being huge cost and energy savings. While this is perfect for some, is it really worth purchasing a new water heater, especially one that is tankless?

What Are The Pros Of Tankless Water Heaters?

1. Tankless water heaters are growing very popular, mostly for the benefits that the product holds. Tankless water heaters work differently than traditional water heaters, where you are using the hot water when you want, not at all times. This means you are saving on money by only paying for the hot water you use, not the hot water you would otherwise be not using, but instead you are continuously running 24 hours, 7 days a week. This means, not only are you saving on money, but you are also being energy efficient by not continuously running water you are not using.

2. Tankless water heaters are usually much smaller than traditional heaters, with the standard sizes being “as small as a small suitcase”, as stated by one of the primary producers of the product, found on the website rinnai.us. This allows for other placements for the product, meaning it is more portable and easier to install than other tankless water heaters.

3. Finally, tankless water heaters are generally guaranteed a longer lifespan than traditional water heaters, as traditional water heaters generally last 12-15 years, while tankless water heaters can last as long as 20 years before malfunctioning.

What Are The Cons Of Tankless Water Heaters?

1. While some details of the tankless water heater makes this product sound perfect for some, there are some cautionary notes you should heed before getting one. For one, upfront costs and installation fees are much more than traditional water heaters, so much that consumerreports.org reports that this water heater is more expensive than traditional water heaters, even if it boasts money savings.

2. This is because the amount saved, subtracted by the installation and upfront costs, means the tankless water heater will take at least 22 years before any actual savings are noticed. This is two years past the water heater’s expiration date. Not only is the water heater more expensive, but common complaints point out inconsistencies with the water heater’s water temperature. While the product boasts allowance of multiple uses of hot water (shower, bath, dishwasher, etc.), many have found that their is colder waters in showers, while their is hotter waters in baths or when running the dishwasher. This means multiple tasks while the tankless water heater might interfere with the water’s overall temperature, as the tankless water heater does not put out as much energy as the traditional water heater. This does save energy, but it also may make for colder showers and colder wash loads, facts that many homeowners would not like to hear. Tankless water heaters usually use more gas or electricity (depending on the source power) than traditional water heaters, but this may balance out depending on the individual’s regular use of hot water. Finally, tankless water heaters usually require more maintenance and care than traditional water heaters, which can be both annoying and costly for those who are not familiar with the tankless water heater.


While some may think the tankless water heater saves on money, you should not use that as a credible reason in buying it. Instead, you should look at the other benefits, as well as risks, on deciding on whether or not you want the tankless water heater. The tankless water heater is good for those who are constantly on the go, and for those who don’t use as much hot water as others. On the flipside, traditional water heaters work well for some people, and if you are happy and content with the current heater you have, you should value that before you decide to transition to a tankless water heater.
