Tankless water heaters, also known as on demand or instantaneous water heaters, have gained immense popularity in recent years. 

Unlike standard heaters, a tankless heater doesn’t store hot water in anticipation of your needs. Instead, it heats water on demand, piping water through the unit and on to your shower, dishwasher, or other appliances. 

It provides hot water exactly when and where it’s needed, offering numerous advantages over traditional storage tank water heaters.

In this blog, we outline the advantages of a tankless water heater systems—including how to choose, install, maintain, and trouble shoot one.

Benefits of a tankless water heater system.


1. Reduced Standby Heat Loss

A tankless water heater reduces standby heat loss from the tank walls and water pipes  Tank style water heaters continuously maintain a tank full of hot water, which allows heat to escape through the tank walls and water pipes. In contrast, tankless heaters only heat water when you need it, eliminating this wasteful energy loss.

2. Instant Hot Water

If you have a tankless system, you won’t need to wait for the storage tank to refill and heat up. As soon as you step into the bathroom and turn on the shower, you’re greeted with an immediate rush of hot water. No more shivering as you wait for the water to heat up. This is the beauty of a tankless water heater – hot water as you need it, when you need it. 

3. Versatility

Picture this: You’re running a load of laundry, your dishwasher is humming, and someone in your house is enjoying a warm shower. In the past, this might have led to a hot water shortage. But with a tankless system, it’s a different story. Tankless water heaters can be used in various applications. This also means that they are perfect for multi-line installation as tankless water heaters can be installed in more than one location within your home.

Expert installers ensure that the unit is set up correctly, including the vent pipe for condensing tankless water heaters, stainless steel water supply lines, and the necessary electrical or gas connections. Proper installation maximizes efficiency and performance.  

A successful tankless water heater installation requires careful consideration of factors like location, ventilation, sizing, and water quality. 

Here’s what you need to keep in mind:

1. Location: Tankless water heaters can be installed both indoors and outdoors. Indoor units are usually placed on walls or in utility rooms, while outdoor units are designed to withstand the elements. The choice of location depends on your space, climate, and local building codes.

2. Ventilation: Proper ventilation is essential for gas-powered tankless water heaters. These units produce exhaust gasses that must be safely vented outside. Ensure that your installation complies with ventilation requirements to prevent potential health hazards.

3. Gas Line and Electrical Supply: Gas-powered tankless water heaters require a gas supply line, while electric models need a dedicated electrical circuit. It’s crucial to have the appropriate connections and wiring in place for a safe and efficient installation.

4. Water Quality: Tankless water heaters are sensitive to water quality. Hard water with high mineral content can lead to scaling inside the unit, reducing its efficiency and lifespan. Consider installing a water softener or descaler if you have hard water in your area.

5. Sizing: As mentioned earlier, selecting the right size is crucial. An undersized unit may struggle to meet your hot water demands, while an oversized one could lead to unnecessary energy consumption. Consult with a professional to determine the ideal size for your household.

As energy costs rise, it will become more economical for many households to switch to tankless heaters. They have a disadvantage, though: Especially in homes with large families, they may not meet everyone’s hot-water needs simultaneously. For instance, a tankless heater might not be able to supply both the dishwasher and the shower at once. Some households install two tankless heaters, or designate a tankless heater to supply only one appliance.
