Tank Or Tankless water heater

Tank or tankless? A tank keeps a supply of hot water ready; a tankless heater heats water only when you open a tap. Both work well in Toronto homes. The right choice depends on your household, your gas line, your venting and your budget.

🛠️ What Installation Involves

  • ✓ Gas line sizing check; tankless units often need a larger line
  • ✓ Venting: PVC for most power-vent tanks and tankless
  • ✓ Water connections, expansion tank and condensate drain
  • ✓ Installation by TSSA-certified gas technicians

💡 Hard water shortens tankless life. A whole-home water softener protects the heat exchanger.
