Utility costs are rising, but with the growing demand for energy-efficient homes, many Calgary homeowners are asking: “Are tankless water heaters better than hot water tank heaters in Calgary?” or “Are tankless water heaters worth it?” If you ever run out of hot water mid-shower or have dealt with a failing tank, switching to a tankless system might make more sense. However, you might wonder if it’s the right investment for your home.
Among other plumbers in Calgary, we want you to choose the most effective water-heating system for your home. That’s why we take your lifestyle, home layout and budget into account. Here’s what you should think about before making the switch!
What is a Tankless Water Heater?
Unlike traditional hot water tanks, which heat and store 40-60 gallons of water at all times, a tankless unit only heats water when you need it. As soon as you turn on a tap, cold water flows through a high-efficiency heating element (gas or electric) and comes out hot instantly and continuously.
The “on-demand” heating eliminates the need for a bulky storage tank. It’s one of the benefits that appeals to Calgary homeowners.
Advantages of Tankless Water Heaters
When it comes to tankless water heaters, there are several benefits. They set them apart from traditional hot water tanks. Here they are:
Endless Hot Water
Stop racing to shower before the tank runs out. Tankless units deliver continuous hot water, which is perfect for:
- Large families
- Homes with multiple bathrooms
- Busy mornings when everyone needs hot water at once
With a properly sized unit, running out of hot water becomes a thing of the past.
Lower Energy Bills
Traditional tanks constantly reheat water, even when you aren’t using it. One of the benefits of Tankless systems is that they heat water on demand, reducing wasted energy.
Calgary homeowners notice savings on their monthly gas or electricity bills when they go tankless. This is especially true when the bitter-cold winter rolls around.
Longer Lifespan
Another difference between standard tank and tankless heaters is that the tankless water heaters last 18–20+ years. This can nearly double the lifespan of tank systems (8–12 years).
This factor alone makes them a great long-term investment, especially for homeowners living in their forever home.
Saves Space
Tankless units are compact and mount neatly on the wall. That makes them perfect for:
- Condos
- Small utility rooms
- Homes wanting to free up storage space
A tankless system fits where a traditional tank cannot. Its ability to adapt to tight spaces is one of its biggest highlights.
Reduced Flood Risk
A large tank full of water can cause a flood if it starts to leak. If you go tankless, you reduce the risk of flooding.

Drawbacks of Tankless Water Heaters
No system is perfect. Before you decide to go tankless, consider the following;
Higher Upfront Cost
Tankless systems have a higher upfront cost than their counterparts. This includes both the system itself and the installation. They tend to require:
- Gas line upgrades
- New venting
- Electrical adjustments
- Additional safety components
Installation costs range from $1,200-$3,500. The price depends on the model and home requirements.
Limited Output for High-Demand Homes
A single tankless unit might struggle to keep up with a home that regularly uses hot water in several places at once. Common examples include:
- Shower + Dishwasher
- Washing Machine + Kitchen Sink
Some larger households might need two units or a high-output model.
More Complex Installation
Tankless water heater installation must follow Calgary’s gas and venting codes. This always requires licensed professionals, which means it isn’t a DIY-friendly upgrade.
Not Ideal for Every Home
Older homes may need electrical panel upgrades or major modifications to accommodate a tankless unit. As a result, the total cost will be much higher.
Comparing the Costs of Tankless vs. Traditional Tanks
How do the costs of tankless water heaters stack up against traditional hot water tanks? Here’s a basic overview:
| System Type | Installed Cost | Lifespan | Energy Efficiency |
| Traditional Tank | $700-$1,500 | 8-12 years | Moderate |
| Tankless System | $1,200-$3,500 | 18-20+ years | High |
As you can see, a tankless system will cost you more upfront. Despite this, it offers significant long-term savings and performance benefits.
Deciding Between Tankless and Traditional Tanks
Tankless water heaters and hot water tanks both have their own perks. Knowing which one is right for you can be difficult. That’s why we put together a basic overview of each one to help decide.
When does going tankless make sense? It might be worth if:
- You have high hot water usage
- You plan to stay in your home long-term
- You want lower utility bills

Sometimes, going back to basics is the better option. Consider this option if:
