Gas Water Heater Replacement for Homes Across the GTA

Signs it is time to call

A shell that weeps, a heater well beyond its expected life that keeps needing repairs, or a household that has outgrown its tank are the usual reasons. So is a switch from rental to owned equipment. Plan before failure: replacing on your schedule beats replacing with a flooded floor.

• Water pooling under the tank
• Rust at the cold or hot fittings
• Rating plate date well past ten years
• Not enough hot water for current use

On the job, step by step

1. Isolate fuel and water, empty the old unit and break its connections.
2. Confirm the vent: a natural-draft chimney connection, or a power-vent through the wall with PVC.
3. Set the new tank on a pan or stand as needed, connect gas with a sediment trap and shut-off, and water with unions and dielectric fittings.
4. Add an expansion tank where the house has a check valve or pressure regulator.
5. Fill, purge, light, and check draft, combustion and gas joints.
6. Remove the old tank for recycling.

GTA houses and what they change

When a furnace is replaced with a high-efficiency model, the old chimney may become too large for a water heater alone, which can cause condensation and poor draft. A liner or a power-vent unit fixes that. Only a licensed fitter may touch the gas side here, and the job may carry a permit or notice. Ask about rental return logistics if you are leaving a rental contract.

Before you pick up the phone

Ask what vent type the new tank will use and whether permits are included. Call (365) 387-8531 with your current tank size and location.
