When a storage tank reaches the end of its life
Most gas and electric storage tanks in Toronto homes last 8 to 12 years before the steel liner corrodes through and the tank starts leaking from the bottom seam — a failure that can't be repaired, only replaced. We match the new tank to your household's draw and recovery needs, confirm the venting and gas line still meet current code, and size it so you're not stuck with lukewarm water during morning showers. If you're weighing whether to stay with a tank or switch to on-demand, see our tankless water heater installation.
Signs your hot water tank needs replacing
- Water pooling around the base of the tank or rust streaks on the bottom — a leaking tank cannot be repaired and needs immediate replacement
- Running out of hot water faster than it used to, or water that never gets fully hot, as sediment buildup eats into capacity
- Rumbling, popping, or banging noises while the tank heats — hardened sediment on the burner plate
- Rusty or cloudy hot water at the taps while the cold runs clear, pointing to interior tank corrosion
- The tank is 10+ years old and you want to replace it on your terms instead of after a flooded basement
- A gas tank's pilot won't stay lit or the burner short-cycles, and the unit is too old to justify the repair
- No hot water at all after a sudden failure and you need a same-day swap
What's included
- On-site assessment of the failed tank, your fuel type, venting, and household hot-water demand to confirm the right replacement size
- Safe draining and disconnection of the old tank, including shutting off gas or power and the cold-water supply
- Removal and haul-away of the old tank and any recycling
- Installation of the new gas or electric storage tank with new flex connectors, dielectric unions, and an updated temperature and pressure relief (T&P) valve and discharge pipe
- Code-compliant venting and gas-line connection for gas units, including draft and combustion checks, or proper electrical hookup for electric units
- Full leak test, thermostat setting, and walkthrough so you know how to operate and maintain the unit
- Cleanup of the work area and the written 25-year workmanship warranty on our installation
Tank types we install
| Type | Best for | Notes |
|---|---|---|
| Gas storage tank | Most homes with existing gas service | Requires venting (atmospheric or power-vent). |
| Electric storage tank | Homes without gas service | Slower recovery; uses two heating elements. |
| Power-vent gas | Homes where atmospheric vent is not practical | Vents through a side wall. |
| Direct-vent gas | Sealed combustion installations | Higher efficiency. |
Tank replacement cost
Pricing depends on tank type (gas, electric, power-vent), tank size, and whether the existing supply, vent, and gas line are reusable. Same-day replacement of a standard 40 or 50 gallon atmospheric vent tank stays in the mid-range. Power-vent or direct-vent gas tanks cost more because of venting hardware.
What to share when you call
- Tank type and size of the existing unit.
- Fuel (gas, electric).
- Brand and approximate age.
- Whether the tank is rented or owned.
- Photos of the tank, vent, and surrounding area.
- Whether the install location is finished or unfinished.
Toronto context
Tank replacements in Toronto need to consider venting (atmospheric vs power vent vs direct vent), gas line capacity (older homes often need an upsized gas line for high-recovery tanks), and water hardness (which determines descaling and anode rod replacement intervals). We size to actual hot-water demand, not nameplate gallons.
What to confirm before approving installation
- Vent type (atmospheric, power, direct) should be matched correctly.
- Expansion tank should be installed when required by the system.
- Pressure / temperature relief valve should be present and properly piped.
Useful info on the call: existing tank type, age, vent style, and rental status.
Frequently asked questions
Can I switch from electric to gas?
Yes when gas service is available and venting can be installed correctly. The conversion adds gas line work, venting, and electrical de-commissioning to the project.
How long does the install take?
Most standard tank replacements complete in 3 to 5 hours. Power-vent or direct-vent installations take longer.
Do I need an expansion tank?
If the home has a PRV or check valve that creates a closed system, yes — the expansion tank handles thermal expansion. Code requires it in many situations.
Should I upgrade to a larger tank?
Depends on household demand. A 40 gallon tank is enough for most 2-bathroom homes; 50 to 75 gallons is typical for larger homes or higher demand.
