Tired of running out of hot water or paying high energy bills? It might be time to consider a tankless water heater in Calgary. Also known as on-demand hot water systems, these high-efficiency heaters have become a top choice for homeowners seeking performance, energy savings, and space-saving benefits.
But is a tankless system really better than a traditional tank? What’s the real installation cost, and how do tankless water heaters work?
Let’s break down the details so you can make the right decision for your home
Tankless Water Heater vs Tank: What’s the Difference?
Traditional Hot Water Heater:
A conventional hot water heater stores 40 to 60 gallons of water in a tank, heating it constantly so hot water is available when needed. While familiar and affordable, tanks can:
- Waste energy keeping unused water hot
- Take up lots of space
- Run out of hot water during peak use
Tankless Unit:
A tankless water heater doesn’t store hot water. Instead, it only heats water when you turn on the tap. Cold water passes through a powerful heating element—gas or electrical—that instantly delivers hotwater on demand.
This difference in operation means:
- No waiting between showers
- Lower energy cost
- Compact wall-mounted design
- Longer lifespan—up to 20 years with proper care
How Do Tankless Water Heaters Work?
When you open a tap or appliance, cold water enters the tankless unit and passes through a heat exchanger. The system measures flow rate and water temperature, and the burner or element activates to heat water on demand.
Once you close the tap, the unit shuts off—meaning you only pay to heat what you use.
This high-efficiency design results in big energy savings, especially in homes with high demand or inconsistent usage patterns.
What’s the Cost of a Tankless Water Heater in Calgary
The tankless water heater Calgary cost varies depending on:

A tankless system can be installed in almost any Calgary home with professional support—even replacing old tanks with minimal disruption.

Pros and Cons: Quick Comparison
How long do tankless water heaters last?
With regular maintenance, tankless units can last 15 to 20 years, nearly double the lifespan of a traditional tank system. Annual flushing and descaling—especially in hard water areas like Calgary—helps prevent scale buildup and ensures consistent performance. Investing in main
tenance now means greater long-term reliability and fewer costly repairs down the road.
Can I install one in a small utility room?
Yes! One of the best features of tankless models is their compact, wall-mounted design. They free up valuable floor space and are ideal for utility rooms, closets, and basements with limited square footage. No bulky storage tank means more room for storage or other systems.
What size do I need?
The right tankless unit depends on your household’s flow rate—how many fixtures you run at the same time. A three-bathroom home with a busy kitchen may need a higher capacity model than a con
do or basement suite. Our techs assess your hot water usage and recommend a model that ensures you’ll never run out of hot water.
Will I need to upgrade my gas line?
In many cases, yes—especially for gas tankless water heaters, which require more BTUs than conventional systems. An undersized gas line can limit performance or cause safety issues. Our certified technicians will inspect your setup and, if needed, safely install or modify your gas line to meet code and ensure peak efficiency.
