Tankless Water Heaters: Go or No?

In some cases, the smaller one thing is, the better. The compact design of one item can give relief and comfort to people, especially those who are on the go. Bringing a smaller item with you gives you more freedom and flexibility to move around as opposed to carrying a bigger, heavier item.

Even in their household, some people prefer using smaller items as part of their everyday routine. For instance, instead of a bulky vacuum cleaner, some homeowners opt for a smaller, handheld design that is easier to carry from one room to another. This is especially convenient for those who live in a smaller space.

But when it comes to your water heater, is it really better to use something smaller? Tankless water heaters are a more compact alternative to the traditional water heater with a tank commonly found in households all across the country. These have also become a popular choice of heater for homeowners, especially those who live in smaller apartment units or condominiums.

Are you selecting your new water heater for your home and are considering installing a tankless water heater in your home? Consider the following pros and cons before you make that purchase:


Tankless water heaters are known to be energy efficient. Unlike the traditional heaters that store hot water in a tank, it only heats up water when needed or when turned on. That’s also the only time it makes use of electricity or power; you can shut it off completely as soon as you’re done. This is an advantage for people who are really mindful of their energy usage and are making a step towards a more energy-efficient household.

With an on-demand system, your tankless water heater makes it easy for you to get access to an almost unlimited supply of hot water in your bathroom or kitchen. Your traditional water heater takes time to collect a limited volume of hot water which eventually runs out, so if you’re the type who needs hot water for a longer period of time, tankless is the way to go.

Of course, its size is one of the biggest factors to consider when getting a tankless water heater. Since it’s relatively smaller than a water heater with a tank, you can easily have it stored under your kitchen or bathroom sink, mounted to a wall, or hidden inside a cabinet. You won’t need a dedicated area just so you can have the unit installed.


As much as tankless water heaters are convenient, they have their share of cons as well. One of the most common problems homeowners have with this type of water heater is the upfront cost of getting one. Buying one and having it installed by a certified plumber can be more expensive than the traditional units, especially if your home isn’t set up to have one installed yet. This can be a downside of having a tankless unit for others.

Although it can provide you with an “unlimited supply” of hot water, the temperature can be inconsistent, depending on the unit you have installed at home. Some people also struggle with finding the right temperature for them to use while in the shower, occasionally experiencing cold water spikes.

One known problem with tankless water heaters is that they require consistent maintenance to prevent any build-up that might decrease their performance and efficiency. They are also equipped with features not present in the traditional heaters that require more care, hence, a more frequent maintenance schedule.
