About this project

Replacement of a residential hot water tank: draining and removal of the old tank, new gas or electric unit, new water and gas connections, expansion tank and drain pan where required, venting to current code, permit and haul-away. Priced by tank size and venting type — the two things that actually move the number.

Questions homeowners ask

How much does a hot water tank cost in Calgary?

A 40–50 gallon hot water tank replacement in Calgary costs $2,290–$3,400 installed in 2026. Power-vent models run $3,100–$4,200, and 60–75 gallon tanks add roughly a third to the unit cost.

How long will I be without hot water?

About four hours. Most replacements are done in a single morning, and we drain, swap and refill in one visit.

How long should a tank last in Calgary?

Eight to twelve years. Calgary's hard water shortens that end, so a tank past ten years with any rust at the fittings is on borrowed time — replacing before it fails costs the same and avoids the flooded mechanical room.
