Lake Louise Inn

Commercial laundry in beautiful Banff

Alberta, Canada

Lake Louise Inn (LLI) is a 247 room resort nestled within the breathtaking Rocky Mountains in Banff National Park, part of a UNESCO World Heritage Site.

Utilizing a PIRANHA T10 to collect the hot wastewater discharge from their laundry systems, Lake Louise reduced their laundry water heating energy demand by as much as 45%.

Our PIRANHA works great and is reliable, I’ve definitely noticed how much less our boilers run because of the reduced load. We love showing our Guests that we take actionable steps towards green energy.

Quick Facts

Lake Louise Inn’s laundry room hot water is propane heated
PIRANHA significantly reduced load & runtime of boilers
32,000 litres propane saved per year
137 MWh/year heat output

Lake Louise Inns PIRANHA T10 wastewater heat recovery system intercepts laundry room wastewater, extracts heat from it and uses that heat to offset the energy required by the hotel to heat water for the laundry.

Results from 2 week audited trial (2018)

Ran an average of 10.7 hours per day
PIRANHA output 375 kWh of heat per day (1.28 million BTU) the equivalent of heating nearly 6,500 litres (1,700 US gallons) of water from 10 to 60°C (50 – 140°F)
PIRANHA reduced propane requirement by 1,240 litres (327 gallons) the equivalent of 1.93 tonnes of CO₂e
