How much does it cost to install a tankless water heater?

Tankless water heater installation in Ottawa typically costs between $3,500 to $5,500, including the unit, installation labor, permits, and necessary upgrades. This is significantly higher than traditional tank water heaters due to the complexity of installation requirements.

The total cost depends on several key factors. The unit itself ranges from $1,500 to $3,000, with gas models generally more expensive than electric. Installation labor adds $1,500 to $2,000, but this can increase substantially if your home needs upgrades. Many Ottawa homes require electrical upgrades for electric units (new 240V circuits) or gas line modifications for gas units, which can add $500 to $1,500 to the project.

Permit requirements in Ottawa add approximately $200 to $400 to your total cost. Tankless water heater installations require both plumbing and electrical permits, and the City of Ottawa has specific venting requirements for gas units that must be followed. Your licensed plumber will handle the permit applications and ensure code compliance.

Additional costs to consider include potential structural modifications if venting routes need changes ($300-$800) and water treatment systems if you have hard water, which can damage tankless units over time. Some Ottawa homes also need upgraded gas meters for higher BTU gas tankless units, which involves coordination with Enbridge Gas.

The investment pays off through energy savings - tankless units are 20-30% more efficient than tank water heaters and last 15-20 years versus 8-12 years for tanks. They also free up valuable basement space and provide unlimited hot water when properly sized.
