How much does water heater installation cost in the GTA?
Water heater installation in Etobicoke and the GTA typically runs $1,200–$2,500 for a standard tank, $4,000–$6,500 for tankless, and $3,500–$5,500 for a heat-pump hybrid. Where you land depends on the type, the capacity your household needs, and what the gas, venting, and water connections require. Here are the typical ranges and what moves the cost.

These are typical GTA installed ranges, not a quote. Your exact price depends on tank vs. tankless, capacity, and what your gas line and venting need to meet code — we assess it and give you a written, all-in price for free.
What moves the price
What actually drives the cost
Tank vs. tankless
A tankless unit costs more to install but gives continuous hot water and frees up space. A tank is cheaper up front and simpler. The choice is the biggest single factor.
Capacity / flow rate
Sized to your household's hot-water demand — by tank size for storage, or by how many hot taps run at once for tankless — so you don't run out.
Gas, venting & water lines
Tankless and high-efficiency units often need a larger gas line and dedicated venting. That's the part that has to be done to code, and it varies by home.
Fuel type & efficiency
Gas, electric, or a heat-pump (hybrid) water heater each install differently — and a hybrid can qualify for an Ontario rebate.
Removing the old unit
Draining and removing the old heater and re-routing connections adds labour, especially when switching tank-to-tankless.
When is it time to replace?
A storage tank typically lasts 8–12 years. If yours is near that, rusty, rumbling, or leaking at the base, it's on borrowed time — replacing on your schedule beats an emergency flood. If you want endless hot water and the floor space back, it's worth comparing tankless while you're at it.

Water Heater Installation Cost FAQs
How much does a water heater cost in the GTA?
A standard tank runs $1,200–$2,500 installed, a heat-pump hybrid $3,500–$5,500 (may qualify for a $500 rebate), and a tankless $4,000–$6,500. The right one depends on your household's hot-water demand and what your gas line and venting need — we give you a written, all-in number for free.
Is tankless worth the extra installation cost?
If you value endless hot water, want the space back, or run out often, yes. A tank is cheaper and simpler up front. We'll lay out both honestly — no pressure to upsize.
Why does a tankless install cost more?
Tankless units fire harder than a tank, so they often need a larger gas line and dedicated stainless venting. That extra work is most of the difference — and it has to be done to code.
Can I get a rebate on a water heater?
A heat-pump (hybrid) water heater can qualify for an Ontario incentive. Standard tanks generally don't. We'll tell you what applies before you commit — see our rebates page.
