What Affects the Cost?

Tank vs. tankless
Standard tank: $1,200–$2,500. Tankless: $3,000–$5,500. Tankless costs more upfront but saves 20–30% on energy.
Tank size
40 gallon (1–2 people): $1,200–$1,800. 50 gallon (3–4 people): $1,500–$2,200. 60+ gallon: $2,000–$3,000.
Fuel type
Natural gas: most common, moderate cost. Electric: cheaper unit, higher operating cost. In Ontario, many homeowners still have rental tanks — buying out the rental saves long-term.
Venting changes
Direct vent or power vent upgrades add $300–$800. Required when switching from atmospheric to high-efficiency.

Canadian Considerations

Many Ontario homeowners rent their hot water tanks from companies like Enercare or Reliance — these contracts can be difficult to break. If your tank is rented, check the buyout cost before replacing. In Ontario, gas hot water tank installation requires a TSSA-certified technician. Québec homeowners benefit from lower electricity rates, making electric tanks more cost-effective than in other provinces.

When to Hire a Pro

Always hire a licensed plumber or TSSA/TSSA-equivalent certified installer for hot water tank replacement. Gas appliance installation is regulated in every province. A typical replacement takes 2–4 hours.
