What are tankless water heaters, and how do they work?

We get this question quite a bit: what are tankless water heaters, and how do they work? These are newer systems, and most homeowners are still familiar with standard (or “traditional”) water heaters. But, tankless units have many advantages, too, and they might just be right for your home.

In this blog post, we’ll review what tankless water heaters are, and what makes them different from standard systems. Read on to learn more!

What are tankless water heaters?

To best explain what tankless water heaters are and how they work, let’s run through their benefits and what makes them different from standard water heaters:

signs you need a new water heater

A standard water heater has a tank, and is typically floor-mounted.

#1. They provide you with constant hot water

This is the biggest selling point of these systems. Tankless water heaters heat water as it’s needed at the faucet, meaning they can provide a constant supply of hot water on demand. This is where they get their technical name: demand-type water heaters.

We all know what it’s like to have the entire family getting ready in the morning. The last person to shower is often the one stuck taking a cold shower. Then, there’s no hot water for laundry or dishes until the water heater “recharges” its supply.

That’s not a problem with a tankless water heater. These systems operate by moving water past heated coils, heating it as needed. Whether its a gas or electric system, these coils are capable of getting water up to the desired temperature and then out to where it’s needed.

#2. They can save space compared to standard water heaters

One of the biggest benefits of tankless water heaters as compared to traditional water heaters is the potential for space savings. Generally, standard water heaters are 60-inch tall and 24-inch wide. They’re floor-mounted, typically in a garage or closet.

In contrast, most tankless systems are just 28-by-20, and they’re typically wall-mounted. This can save your floor space.

Tankless water heaters are wall-mounted, and do not carry water in a tank.

#3. They last longer than normal water heaters

Traditional water heaters have a typical lifespan of 10 to 12 years. The lifespan of tankless water heaters is about double that. They can last as long as 20 years when properly maintained by a professional plumber. If you plan to stay in your home for a long time, a tankless water heater is the best choice, since an increased lifespan means greater cost savings in the long run.

#4. They’re more energy-efficient, too

The operating cost of tankless water heaters is much lower compared to traditional water heaters. These systems use significantly less electricity or gas to heat up the water because they heat water when it’s needed, instead of having to keep water heated in a tank for use.

As a result, you will be able to save a lot due to reduced energy usage. The annual savings can amount to $100 when using Energy Star tankless water heater, according to the U.S. Department of Energy.

The verdict?

The reality is that tankless water heaters have many advantages over standard “tanked” systems. The trade-off? They cost more upfront.

However, if you’re planning on owning your home for a long time, it’s pretty likely that the energy savings of the system will eventually catch up and pass the increased initial investment. That’s in addition to the convenience these systems represent in your home.
