Convert your old tank to a high-efficiency Rinnai tankless system in Calgary from $3,200 all-in — including the unit, City of Calgary permit, ATCO Gas line check and disposal of your existing tank. Typical local market pricing for comparable tankless installs is often $4,500–$8,500.
You only pay once a vetted Calgary installer accepts your job.
Calgary winters routinely hit −25 °C and incoming groundwater drops near 2 °C in January. A correctly-sized Rinnai tankless delivers a continuous 60 °C+ temperature rise — meaning back-to-back hot showers even on the coldest Chinook morning. Combined with the elimination of standby heat loss, most Calgary homeowners see 25–35% lower gas bills inside the first year.
Every Calgary tankless quote on the platform is all-in. Standard scope, code items, and taxes are shown clearly before booking.
If you're converting from a 40-gal tank, your existing 3/4″ gas line probably isn't sized for the 199,000 BTU draw of a high-output tankless. Most pre-2010 Calgary homes (Bridgeland, Kensington, Bowness, Mount Pleasant) need a 1″ line run from the meter — that's $1,000 extra, total $4,200 all-in. Newer builds in Mahogany, Cranston, Seton, Auburn Bay and Evanston usually pass inspection as-is.
