If your water heater is over 10 years old, you're facing a decision: replace with the same traditional tank or upgrade to tankless. Here's the honest comparison for GTA homeowners.
Traditional Tank Water Heaters
Pros: Lower upfront cost ($800–$1,500 installed), simple reliable technology, works well for most households.
Cons: Standby heat loss keeps water hot even when you're away, can run out during peak demand, shorter lifespan (10–12 years).
Tankless (On-Demand) Water Heaters
Pros: Endless hot water, 20–35% lower energy bills, 20+ year lifespan, compact size, eligible for government rebates.
Cons: Higher upfront cost ($2,000–$3,500 installed), may require gas line upgrade, flow rate limits with simultaneous use.
Which Should You Choose?
Choose tank if: you're on a tight budget, have a small household (1–2 people), or your gas line can't support tankless without expensive modifications.
Choose tankless if: you have a family of 3+, you frequently run out of hot water, or you care about long-term energy savings.
