How much does tankless water heater install cost in New Brunswick?

Tankless water heater installation in New Brunswick typically runs $3,500-$8,000 total, with the unit itself costing $1,800-$4,500 and installation adding $1,700-$3,500 depending on your home's setup and fuel type.

Gas vs Electric Considerations
Gas tankless units are generally more cost-effective to operate but require significant upfront work. If your home currently has an electric tank, converting to gas tankless means running a new gas line ($800-$2,200), installing proper venting through the roof or wall ($600-$1,500), and potentially upgrading your electrical service for the unit's controls. Propane tankless is popular in rural New Brunswick where natural gas isn't available — expect similar installation costs but factor in propane tank rental or purchase.

Electric tankless units avoid gas line work but often require electrical upgrades. Most need 240V circuits with 100-200 amp capacity. If your panel can't handle the load, an electrical upgrade ($2,000-$5,000) may be necessary before installation.

Permit and Code Requirements
All tankless installations require permits in New Brunswick. For gas units, your licensed plumber must obtain a gas installation permit from TIS (Technical Inspection Services) at 1-888-659-3222, and TIS will inspect before the unit can be used. Electric units need an electrical wiring permit from NB Power (1-800-615-0522) if new circuits are installed. The installation must comply with National Building Code 2020 standards, including proper clearances and venting.

Installation Complexity Factors
Your existing setup heavily influences cost. Replacing an electric tank with electric tankless in the same location runs $2,500-$4,000. Converting from oil or electric to gas tankless, especially if the water heater is in a basement far from an exterior wall, can push costs to $6,000-$8,000. Older New Brunswick homes often need additional work — upgrading galvanized supply lines, installing expansion tanks, or addressing hard water issues that can damage tankless units.

Professional Installation Required
This isn't a DIY project. Gas work requires a licensed gas fitter, electrical work needs a licensed electrician, and plumbing modifications need a licensed plumber — all licensed through TIS. Working without permits risks insurance coverage and creates safety hazards. Get quotes from at least three contractors and verify their TIS licensing and WorkSafeNB coverage before starting work.

Consider NB Power rebates for high-efficiency models, and factor in your household's hot water usage — tankless units excel with consistent demand but may struggle with simultaneous high-draw applications in larger families.
