Facts Homeowners Should Know About Tankless Hot Water Heaters

Tankless hot water heaters have become a popular choice for homeowners in recent years. Traditional tanks have a limited hot water reservoir that can take time to refill and heat, while tankless units heat the water on demand. If you’re fourth in line for a hot shower, you won’t have to worry about getting freezed out when you turn on the tap!

If you’re considering a tankless heater for your home, our team at Weiss-Johnson can help you find the perfect unit. Below, we’ll discuss a few facts about these heaters so you can decide whether a tankless unit is right for you. Keep reading to learn how you can get expert water heating services in Edmonton from the Weiss-Johnson family. 

Tankless Heaters are Energy Efficient

Nowadays, everyone is looking for ways to save on their utility bills (especially homeowners who foot the full bill). A major draw to tankless water heaters is their ENERGY STAR-certified rating. On average, homeowners can save up to 30% on their hot water bill with a tankless unit compared to a traditional unit, making it a great choice for cutting costs! 

Enjoy the Extra Space

Traditional hot water tanks aren’t exactly small, generally holding around 40 to 60 gallons of water. These units can usually be found in a dedicated furnace room, taking up valuable space that you can put to other uses. Tankless hot water heaters, on the other hand, are smaller, wall-mounted units that free up valuable space in your furnace room. 

What “Endless Hot Water” Actually Means

One of the biggest benefits of a tankless hot water heater is its on-demand hot water supply, but even this “endless” heat has its limits. 

Tankless units can only deliver a set number of hot water gallons per minute (GPM), usually around 2-5 gallons, depending on the model (gas units can generally handle more). 

Every water fixture and appliance requires a specific GPM to work. Showers typically use 2.5 GPM, while a dishwasher needs 3-4 GPM. If you try to run both simultaneously, you may hit your system’s maximum draw and get a blast of lukewarm water from your shower head.

Long-term Savings with an Upfront Price Tag

Tankless water heaters are a money saver when it comes to the utility bills, but they do have a higher upfront installation cost. If you live in an older home, your venting and gas lines may need to be updated to properly integrate your heater into your HVAC system. Our technicians at Weiss-Johnson can help assess your current setup and family’s hot water needs and provide you the information to help you make the best decision for your family.

Is a Tankless Hot Water Heater Right for You?

There are many positives to opting for a tankless heater. These units have a long, serviceable lifespan, help homeowners save big on utility bills and make a showering experience much more enjoyable knowing that you don’t have a time limit on your hot water. That said, tankless units are limited in how much hot water they can draw at once and have a higher upfront cost. 


Weigh the pros and cons to see what works best for your family’s home. Our team at Weiss-Johnson can help you find a tankless unit that aligns with your household’s hot water demand and your personal budget!
