The Ins and Outs of Tankless Water Heaters

Learn how tankless water heaters can save homeowners money, reduce water consumption, and lower fossil fuel emissions.
Published:  November 3, 2022

Hot water tanks provide hot water to homes and facilities across the country. However, if you are building a new home, remodeling your home, or needing to replace your hot water tank, you may want to consider an alternative to the standard hot water tank.

Rather than paying to have a large water tank that requires water to sit in the holding tank, tankless systems quickly heat water only as you need it.

If you want to get rid of your old water heater and save a lot of money, switching to an on-demand water heater may be best. These tankless water heaters offer an economical solution and allow you to warm your water as needed.

This article will discuss the different types of heating systems available for homeowners and how they work.

It will also discuss the benefits and drawbacks of the tankless water heater system and what to consider when choosing what type of system to install.

What is a Hot Water Heater

A tankless water heater is an alternative to traditional water heaters. A tankless water heater does not store hot water in a tank but instead heats it on demand.

They are generally more efficient than conventional storage tanks, and some offer innovative options that integrate with your smart home technology.

All incoming water is heated as it moves through the system, so no extra storage tanks are needed. If your house only has a furnace room or basement, this can be the perfect solution for a streamlined setup.

There are several options for tankless instantaneous water heaters, such as condensing and non-condensing.


A condensing water heater uses a dual heat exchange, making it more efficient because it heats the water before it gets to the heat exchanger, which means it uses less energy.

These units can be used in places like homes and commercial spaces. They're often used because they save a lot of energy and are effective at extracting heat from the atmosphere.


Non-condensing tankless water heaters use a single heat exchange, don't have a condensation chamber, and use more exhaust gasses to generate heat.

What You Should Know About Tankless Water Heaters

New Jersey's homes tend to be built with a big hot water tank in their basements. They're seen as an essential part of our homes, and we're all accustomed to seeing them.

Tankless water heaters have a different look than traditional systems, but they are small, so they should fit in any room, as they typically hang on a wall.

Here are the ins and outs of tankless water heaters that should be considered before buying one.

They Provide Instant Hot Water

After completing the task of flushing cold water out of the pipes, tankless water heaters provide an endless stream of hot water.

A consistent source of heating on-demand can be provided by these units, even with the absence of storage tanks.

While the size of a tank can limit hot water capacity, tankless heaters make it much easier to have hot water whenever you need it.

You won't run out and have an unpleasant surprise when your shower runs cold at the beginning of your day.

They Last Longer Than A Hot Water Tank

Tankless units are popular because they can last up to twice as long as their tanked counterparts.

Highly efficient, too! A standard water heater will only last between eight to twelve years, and a tankless model can go for more than twenty years.

Opting for the longer-lasting tankless model can save a homeowner from needing a replacement every ten years.

This is because most tankless models have replaceable parts. They are easily repaired, which leaves less of a long-term impact on the environment.

The Monthly Cost Is Lower

Tankless water heaters are more efficient than standard water heaters, saving you a lot of money on utility bills over time.

Because the water is heated instantly, you no longer have to run the water for a long time to reach your desired temperature.

You may not see a huge difference in monthly savings, but, over time, you will save hundreds.

They Are Space-Saving

Tankless water heaters are typically compact and barely noticeable. The savings in space that come with downsizing are a welcome benefit to many people in the area.

A tankless water heating system can free up needed space in your house where people would typically use tanks.

They Conserve Energy

A water heater in a building continuously runs to maintain the temperature of the water.

As time goes on, standing water in a tank begins to lose heat and evaporate.

With water heaters, because water is heated quickly and only when it's needed, it's more energy-efficient. These tankless water heaters save you money on your utility bills in the long run.

In terms of the environment, tankless water heaters are an eco-friendly option for homeowners to consider. They use renewable energy and can be repaired easily.

Drawbacks to Tankless Water Heaters

The drawbacks are usually easily outweighed by the benefits of using a tankless water heater. But there are still a few things to think about before deciding whether or not to use them:

  • Installation costs: If you have a water heater needing replacement, think about switching it out for a tankless model. It'll save you money and more time down the line by cutting out the need to refill water tanks. Making the switch to a tankless water heater may require some new venting and gas lines to be installed. However, you'll only need to pay back the cost of these changes when they're put into use. The energy savings don't begin until then.
  • Water output: Many households need hot water access for more than just one household appliance, making the 60-gallon tank a convenient idea. Tankless water heaters are more efficient, but they may not be the best choice if you want to make sure you don't run out of hot tap water. That's why it's best to get a model that offers a greater output than what your home needs and a recirculating unit.
