Most people only see a water heater installed once or twice in their lives, so it’s fair to wonder what you’re actually paying for. Is it just “swap the old tank for a new one”? Not quite — a proper installation in Edmonton involves gas work, venting, code requirements, and a permit. Here’s the whole process, start to finish, so you know what a job done right looks like (and can spot one done wrong).
Replacement install vs. brand-new install
There are really two kinds of installation. A replacement puts a new unit where an old one already lives — the gas line, venting, and water connections exist, though older setups often need updating to current code. A brand-new install adds a water heater where there wasn’t one: a basement suite, a garage development, or a second unit for a big household. New installs involve running gas and venting from scratch, which is more work but gives you the freedom to put the right unit in the right place.
In Edmonton this split often follows the neighbourhood. In older areas like Mill Woods or Pleasantview we’re usually replacing an original or second-generation tank — and bringing 1970s-era venting up to today’s code while we’re at it. In newer southeast communities like The Meadows or Tamarack, it’s more often a basement development or a tankless conversion.
Yes, you need a permit (and it protects you)
A gas-fired water heater installation in Edmonton requires a gas permit, and the work has to be done by a licensed gas fitter. That’s not red tape — it means the connection, venting, and combustion air are inspected against code, which matters a lot for something that burns natural gas in your basement. A legitimate installer pulls the permit as part of the job. If a quote is suspiciously cheap and nobody mentions a permit, that’s usually why.
What install day looks like, step by step
- Shut off gas and water, then drain the old tank — the slowest step if sediment has built up, which in Edmonton’s hard water it usually has.
- Disconnect and haul the old unit out (tanks weigh a lot; tight basement stairs are our problem, not yours).
- Set and level the new unit, then connect water, gas, and venting — updating any of it that no longer meets code.
- Fill the tank, purge the air, relight or fire up the unit, and set the temperature.
- Leak-test every connection — gas with a detector, water by eye — and run a full heat cycle before we leave.
A standard tank replacement is a same-day job, typically a few hours. A tankless installation usually takes a full day because the gas line often needs upsizing and the venting is completely different. A brand-new install depends on how far the gas and venting have to travel.
How to prep (it takes five minutes)
- Clear a path from the door to the mechanical room — old tanks leave the same way new ones come in.
- Move anything stored against or on top of the water heater.
- Know where your main water shut-off is, in case you ever need it when we’re not there.
- Plan for a few hours without hot water — the cold water keeps running throughout.
The corners a good installer never cuts
Almost every “cheap install gone wrong” call we get comes down to the same shortcuts: reusing venting that doesn’t match the new unit, skipping the permit, no drip leg on the gas line, or a discharge pipe missing from the relief valve. None of these stop the heater from making hot water on day one — they show up later, as carbon monoxide risk, a failed home inspection, or a voided warranty. When you compare quotes, you’re comparing whether these things are included.
