Boilers in Pembroke fall under the Technical Standards and Safety Authority (TSSA), which administers Ontario’s Technical Standards and Safety Act, 2000. The Boilers and Pressure Vessels regulation, O. Reg. 220/01, covers design registration, inspection and certificates of inspection. O. Reg. 219/01 covers licensing of operating engineers.
January design temperatures in the Ottawa Valley sit around -28 °C, colder than Ottawa itself. Boilers run near full load for long stretches, and an overnight trip can freeze lines and coils quickly. Before the heating season we check low-water cutoffs, flame safeguards and controls. We also look at condensate return and feedwater, since many winter failures start in the system around the boiler.
