Tank vs tankless — which is right for a Calgary home?
Tank water heater
- Lower upfront cost
- Simpler installation — direct replacement
- Works well for most Calgary households
- Standby heat loss (heats water even when not in use)
- Lifespan: 10–15 years
- Runs out of hot water if demand exceeds tank size
Tankless (on-demand)
- Higher upfront cost
- May require gas line or electrical upgrade
- Endless hot water — never runs out
- No standby heat loss — more efficient
- Lifespan: 20+ years
- Higher flow rate needed for simultaneous use
When to replace vs repair your water heater
Unit is 10+ years old
Replace — the average lifespan of a tank water heater in Calgary is 10–15 years. Repair costs on an aging unit rarely make sense.
Rust-coloured water from hot taps
Replace — the tank is corroding internally. This cannot be repaired and the unit will fail soon.
Water pooling around the base
Replace — a leaking tank cannot be repaired. Turn off the water supply and call a plumber promptly.
Rumbling or popping sounds
Flush the tank first (sediment buildup). If the noise persists after flushing, the tank is likely near end of life.
Pilot light keeps going out (gas unit)
Repair first — this is often a thermocouple issue, a relatively inexpensive fix. Replace if the unit is old.
Not enough hot water
May be a thermostat or element issue (repairable) or simply an undersized tank for your household. Get a diagnosis first.
