Tankless water heaters are the most efficient form of heating water, which makes them the best choice for high-demand areas such as bathrooms.
These energy-efficient devices use much less electricity than traditional tank-style water heaters and they also save you money over time. In this guide, we’ll explain what a tankless water heater is, how it works, and why it’s so effective at cutting energy costs. We’ll also look at the pros and cons of each type of tankless water heater available on the market today.
What is a Tankless Water Heater
Tankless water heaters are designed to save energy. They can be found in homes around the world. The main advantage of using tankless water heaters is that you don’t have to worry about filling your tank with hot water. With tankless water heaters, you can simply turn on the tap and get the right temperature of water. This is different from traditional water heaters, which rely on a tank of hot water.
A tankless water heater differs from the traditional tank-style water heater in a couple of ways. Traditional models rely on a storage tank to hold water until it’s ready to be used. In contrast, a tankless heater uses a series of pipes that carry the water directly to the faucet. The pipes are heated by a small burner, called a “riser”, which is usually located near the faucet.
Tankless heaters can be controlled manually or automatically. You can also add a programmable timer to regulate the temperature and shut off the water after a certain period of time. You can use a tankless heater to heat only a single unit (like a bathroom) or the entire house. Tankless heaters are energy efficient, and they allow homeowners to control their hot water usage.

Types of Tankless Water Heaters
There are two types of tankless water heaters, non-condensing and condensing. Below we will learn about these types of tankless water heaters in details.
Non-condensing tankless water heaters heat water directly from the water supply and deliver hot water to your fixtures without the need for an air vent. They also provide greater water pressure, so you won’t have to wait for the hot water to trickle out of the faucet.
Condensing heaters release heated air and water through a vent pipe, which is where the water vapor comes from. This means that the water doesn’t get hot until the vapor is released and becomes liquid. While this makes it more energy-efficient, it means that the temperature of the water delivered to the faucet isn’t as consistent as with non-condensing heaters.
Tankless Water Heater Pros and Cons
Below we will list out the pros and cons of tankless water heaters so you can decide if this is the right solution for your home.

How to Choose the Best Tankless Water Heater
To find the best tankless water heater, look for features that make it easy to use, energy-efficient, and affordable. Look for a model that has a sensor, which turns the water heater on when you turn on the faucet.
Make sure the model has a digital thermostat, which lets you set the temperature according to the room in which you use the water. In other words, the hotter the water, the faster the unit will heat it up.

Tankless heaters usually come in three types: electric, gas, and dual fuel. Electric tankless heaters are easier to install, though gas and dual fuel heaters can work in any location.
Look for a heater that has a high-efficiency rating and is well-insulated. For example, if you live in a very cold climate, you may need to choose a heater that is rated for use in -20°C or colder.
Also, look for a tankless water heater that has a built-in filter to keep the water clean and free of debris. Also, make sure it’s easy to remove the heating element to clean it.
