Is tankless right for your home?
Tankless works best where you have adequate gas supply and want endless hot water. Homes with hard water need annual descaling to protect the heat exchanger — we include a service kit and isolation valves on every install.
Installation details
Many older Vaughan homes need a gas line upsize and dedicated venting for a tankless unit. We handle permits, gas sizing calculations and clean interior or exterior venting installations.

Common tankless water heater service questions
How much does tankless installation cost?
Straight swaps are more affordable than first-time conversions, which may need gas line and venting upgrades. We assess your setup and give you a firm quote before starting.
Will I really never run out of hot water?
Correct — as long as the unit is sized for your peak demand, hot water flows continuously. We size by fixture count and simultaneous-use patterns.
How often should I descale?
Once a year for Vaughan's moderately hard water; every 6 months if you have a water softener bypass or notice reduced flow.
