Hot water tank installation in Toronto and the GTA. A storage tank is still the simplest and lowest-cost way to get hot water. The right choice depends on how your current tank is vented, how much hot water your household uses, and whether you have gas.

Tank Installs by Bison Air
🔀 Types of Hot Water Tanks
| Type | How it vents | Good fit for |
|---|---|---|
| Gas, chimney-vented (natural draft) | Up the existing chimney | Homes where the chimney is lined and still in use |
| Gas, power-vent | A fan pushes exhaust out the side wall through plastic pipe | Homes with no usable chimney, or after a high-efficiency furnace was installed |
| Electric | No venting | Homes without gas, or where venting is not possible |
| Indirect (boiler-heated) | Uses the boiler's venting | Homes with a boiler; see boiler installation |
⚠️ The Orphaned Water Heater Problem
When an old furnace is replaced with a high-efficiency model that vents out the side wall, the water heater is often left alone on a chimney sized for two appliances. The chimney can then draft poorly and may push exhaust back into the house. We check the venting on every tank job, and recommend a power-vent tank, a chimney liner or a tankless unit when the chimney is no longer suitable.
📏 What Size Tank Do You Need?
| Household | Typical gas tank size |
|---|---|
| 1 to 2 people | 40 gallons |
| 3 to 4 people | 50 gallons |
| 5 or more, or a large soaker tub | 60 gallons or more, or consider tankless |
These are starting points. We check your fixtures and how your household uses hot water before recommending a size.
