When your water heater fails (and in Calgary, it’s always at the worst possible time), you face a choice: replace with a conventional tank or upgrade to tankless? Here’s an honest comparison.
Conventional Tank Water Heaters

Cons:
- Shorter lifespan (8–12 years)
- Standby heat loss (heating water 24/7)
- Can run out of hot water during high demand
- Takes up floor space
Tankless (On-Demand) Water Heaters
Pros:
- Endless hot water — never runs out
- 20+ year lifespan
- 20–30% energy savings
- Wall-mounted, saves floor space
Cons:
- Higher upfront cost (,000–,000 installed)
- May need gas line or electrical upgrades
- Slight delay before hot water arrives
- Annual descaling recommended in Calgary (hard water)
