Tankless Water Heaters: Pros And Cons

April 28, 2023 | Blog

Have you been thinking about becoming a proud owner of a tankless water heater for your home, but don’t know if it’s the right choice?

Gotelli Plumbing is here for you! Weighing the pros and cons of owning an efficient hot water heater can be a bit overwhelming, but we’ve got you covered with a list of the advantages and disadvantages that come with owning one. Read below to find out whether a tankless water heater will be a great fit for you and your family’s needs!


Tankless units come with many benefits, including:

Long Lifespan

When getting a water heater installed, it’s important to know how long it’ll last before you need to think about a replacement. Luckily, tankless units have a lifespan much longer than traditional water heaters!

These systems do require regular maintenance in order to work properly year-round. If you plan on staying in your home for a while, this might be the one for you!

Doesn’t Take Up A Lot Of Space

When you think about a water heater, it’s easy to imagine a huge tank that takes up a lot of space in your garage, but tankless water heaters don’t have this issue. These smaller systems contain a heat exchanger that heats water as it passes through, without needing to store it, so they can be installed just about anywhere!

Whether you want it outside or in your garage, you’ll be impressed by how little space it takes up. Additionally, the size is so compact that it works great in apartments and smaller homes.

Cost And Energy-Efficient

Traditional heaters have nothing on tankless water heaters when it comes to heating your water up fast. With this on-demand unit, you’ll receive warm water fast when you need it the most. They work seamlessly to instantly warm the water running throughout your home. And their cost-efficiency means you’ll save money in the long-run by reducing water usage and energy consumption.

Supplies Great Water Quality

Another plus when it comes to these water heaters is that they provide healthy water throughout your home, especially when paired with a water softener. Without regular maintenance and flushing, tanked water heaters contain standby water which can harbor bacteria. Since tankless water heaters instantly provide hot water when it’s needed – you won’t have to worry about if it’s fresh or not.


While there are great advantages to owning a tankless system, there are also some drawbacks to consider, including:

Limited Water Supply

A downside to tankless units is that they only allow a limited amount of hot water to flow through the system at one time. By heating water on demand, when many fixtures and faucets want to use hot water all at the same time, you’ll see a difference in performance.

Depending on how much your household demands hot water on a regular basis, investing in more than one tankless unit may be necessary.

Upfront Investment

The overall price will vary based on your preferred fuel source and other features you prefer, but the initial cost of a tankless system at the time of installation is usually more than a tanked unit. Any plumbing and electrical updates required to install the unit will also impact the price, but the savings you’ll see on your utility bill will reap significant long-term savings.
