About this project

Conversion from a conventional tank to an on-demand tankless water heater: new wall-mounted unit, upsized gas line where required, stainless venting, isolation valves for descaling, condensate management, permit and removal of the old tank. Calgary's hard water makes the descaling valves non-optional — they are in every package here.

Questions homeowners ask

Is a tankless water heater worth it in Calgary?

It is worth it if you run out of hot water, want the floor space back, or plan to stay ten-plus years — a tankless unit lasts roughly twice as long as a tank. It is not worth it purely as an energy saving: the payback on gas alone is long at Alberta rates.

How much does tankless installation cost in Calgary?

A tankless conversion costs $5,490–$6,600 for a standard install in 2026, and $7,400–$9,000 for a condensing unit with recirculation. Upsizing the gas line is the most common cost surprise, which is why it appears as its own line.

Does Calgary water damage tankless units?

Calgary's hard water scales heat exchangers, so annual descaling matters. Every install here includes isolation valves so the flush takes twenty minutes rather than a plumbing call.
