Tankless Water Heater Installation in Windsor Ontario

Gas tankless water heater installation typically runs $2,500 to $4,500 installed for a condensing unit, while electric tankless models generally run $1,800 to $3,000 installed. Costs increase where the gas line needs upsizing, which can add $500 to $1,500, or where an electric panel upgrade is needed, which typically adds $500 to $2,000. We provide a firm number after assessing your mechanical room rather than a rough estimate over the phone.

For most households, yes, over the unit's lifespan — tankless units typically last around 20 years versus 10 to 12 for a tank, use less standby energy since they're not keeping water hot around the clock, and never run out mid-shower. The tradeoff is a higher upfront installation cost and sometimes added gas line or electrical work, so the payback period depends on your household's hot water usage and current energy costs.

Yes — gas tankless installations require a TSSA-licensed gas technician and a permit for the gas connection and venting work, and electric tankless installations require Electrical Safety Authority (ESA) permitting for the dedicated circuit. We handle both as part of the installation.

High-efficiency tankless water heaters have, at various times, qualified for support under the federal Canada Greener Homes Grant and Enbridge Gas conservation rebates, generally as part of a broader home energy retrofit or audit. Program terms and funding availability change, so we'd recommend confirming current eligibility before counting on a specific rebate amount.

Running out of hot water regularly with multiple people or appliances using it at once, wanting to reclaim the mechanical room space a tank occupies, or simply having an aging tank that needs replacing anyway are the most common reasons homeowners switch. If your household's hot water demand has grown — new bathroom, more people living at home — a tankless unit often solves the problem better than upsizing a tank.

A conventional tank keeps 40 to 50 gallons of water hot at all times, ready to draw from but also losing some heat continuously. A tankless unit heats water only as it flows through, providing continuous hot water without a storage tank, at the cost of a higher upfront installation price and specific gas or electrical infrastructure requirements a tank doesn't need.

We assess gas line capacity, venting path and electrical panel before quoting, so you're not stuck with an undersized unit that can't keep up with your household. Our technicians handle both gas and electric installs and explain the tradeoffs honestly instead of pushing whichever unit is easiest to install. Pricing is clear before work starts, and most of our tankless installs come from homeowners replacing a tank that finally gave out.
