Hot water system selection matters more than most Ontario homeowners realise. Here is a complete 2026 comparison. **Traditional Storage Tank** Most common in Ontario. 40-60 gallon gas or electric. Gas EF 0.6-0.7. Lower install cost ($800-$1,400). Simple maintenance. Standby heat loss is the main inefficiency. **Tankless (On-Demand)** Heats only when needed. Gas EF 0.8-0.98. Install cost $2,000-$4,000. Requires 3/4 inch gas line typically. Virtually unlimited hot water — but flow rate limited. Size carefully for simultaneous demand. **Heat Pump Water Heater (Electric)** Extracts heat from ambient air. EF 2.0-3.5 — dramatically more efficient than resistance electric. Requires ambient air source in basement or utility room. Canada Greener Homes Grant rebates available. Cost: $1,800-$3,500 installed. **Rental vs Purchase** Many Ontario homes rent from Reliance, EnerCare, or Direct Energy. Ownership cheaper over 7+ years. When buying a home, check for rental agreements on title — some carry buyout penalties. **When to Replace** Lifespan: 8-12 years. Signs: rust in hot water, rumbling (sediment), visible corrosion, pilot issues, age over 12 years. Compare hot water options and get Ontario quotes at home.renovation.reviews.
