Cost to run
Yearly running cost — what most cost guides skip
Install price is only half the story. Over 10 years, the fuel bill often outweighs the price difference between models. National operating-cost estimates below (FTC EnergyGuide):
| Type | Per year | 10-year fuel |
|---|---|---|
Heat pump water heaterCheapest to run Cheapest to run — pulls heat from the air, ~3–4× more efficient than resistance. | $130 | $1,300 |
Gas tankless On-demand gas; no standby loss, so cheaper to run than a gas tank. | $270 | $2,700 |
Gas storage tank Low running cost where natural gas is cheap; some standby heat loss. | $330 | $3,300 |
Electric tankless On-demand electric; needs a heavy electrical service upgrade. | $500 | $5,000 |
Electric storage tankThis page Cheapest to buy, most expensive to run at national electricity prices. | $570 | $5,700 |

Rebates & tax credits
The federal 25C tax credit for high-efficiency water heaters ended December 31, 2025 and is not available for 2026 installs. Many gas and water utilities still offer their own rebates on ENERGY STAR condensing gas tanks — check your provider and the DSIRE database — and the lower running cost adds up over the tank's life.
Cheapest time for tank water heater replacement in Ontario
An aging tank tends to give out in winter, when it's working hardest against cold incoming water — and that's exactly when replacement costs the most. Get ahead of it.
Why tank water heater replacement quotes vary — and how to compare them fairly
Big gaps between bids come down to scope far more often than greed. This breaks down the levers and how to force a like-for-like comparison.
Why a quote looks high (or low)
- Removal and disposal of the old unit is sometimes a hidden add-on.
- Code work (expansion tank, venting, drain pan, straps) may be excluded from a low bid.
- Fuel type and first-hour/GPM sizing change the equipment cost.
Get an apples-to-apples bid
- Decide tank vs. tankless first, then compare like models.
- Ask whether code upgrades (expansion tank, venting) are included.
- Match the first-hour rating / GPM to your household size.
- For tankless, ask if the gas line or electrical panel needs upgrading.
Questions to ask Ontario Water Heaters pros
The only honest way to compare is to hold every quote to one checklist. Start with these.
- 1Will the new unit meet current code (expansion tank, venting, seismic straps, drain pan)?
- 2Is removal and disposal of the old heater included in the price?
- 3For tankless: does my gas line or electrical panel need an upgrade?
- 4What's the first-hour rating / GPM, and is it sized for my household?
- 5What does the warranty cover, and who handles warranty service?

What affects tank water heater replacement cost the most?
Start with the fundamentals — replacing a standard storage-tank water heater, including the unit and installation. What moves the price most: equipment or material grade, your home's size and complexity, local labor rates, and the mixed climate zone.
Tank or tankless — and what should you budget?
Tank, tankless or heat-pump — the format you pick shapes the bill today and the utility bill for years after. Our editors weigh the trade-offs.
The simple-swap case
When money is the constraint and the existing tank has kept up with the household, dropping in the same fuel type and capacity is the least disruptive move. No venting rework, no new gas line, no panel space to find — a plumber can pull the old unit and set the new one before lunch.
The heat-pump case
A hybrid heat-pump unit carries the steepest sticker price and draws the largest utility rebates on the market, then pays that back by pulling warmth from the surrounding air instead of generating heat — operating cost falls to a fraction of a standard electric tank's. The condition is location: it wants a roomy, temperate spot like a garage or basement to perform.
The tankless case
Tankless costs more upfront and may need a gas-line or electrical upgrade, but it lasts longer, never runs out of hot water and trims standby energy loss — strongest for larger households planning to stay put.
Match the format to your household and how long you'll stay. Tank for tight budgets, tankless for endless hot water, heat-pump for the lowest running cost and biggest rebates.
