As part of the Action Centre’s Recreation Energy Conservation Program, the Town of Trochu replaced six (6) furnaces with high-efficiency models and two (2) conventional storage tank heaters with three (3) tankless water heaters at the Trochu Arena.

The project was commissioned in January 2021.


The Trochu Arena runs at full capacity from September to March and there is a lot of hot water usage for showers during this period.  Storage tank water heaters were upgraded to tankless water heaters that are 24% –34% more energy-efficient than conventional storage tank water heaters. In addition, the existing furnaces that serve the changing rooms, lobby, ice plant, and curling rink were in poor to fair condition. To improve the facility’s existing heating system, there was a one-to-one replacement of six (6) 40-year old furnaces with 96% efficient condensing furnaces.                     


The replacement resulted in a reduction of 16 tCO2/year and an energy cost savings of $2,315.41/year The project resulted in a 19% GHG reduction from the existing system and a 6% reduction facility-wide from the baseline.

“The Town of Trochu is extremely pleased to play a part in reducing our carbon footprint and energy conservation measures. The original furnaces and water heaters in our arena were 40 years old and not very efficient. The MCCAC REC grant gave us the opportunity to decrease the energy used by our arena clients, residents, and visitors. It will help us to reduce operating costs. The grant was greatly appreciated to assist with replacement costs and afford us the ability to upgrade our heating systems.”
