Combustion safety testing in Regina

A combustion safety test checks that your furnace, water heater and fireplace vent their exhaust outside instead of into the house, which matters most right before and after you tighten the house up. In the Regina area, the main heating energy is natural gas for 70% of households.

How Regina is built

Regina's houses by when they were built Ten house shapes, one for each tenth of Regina's 69,170 houses. Before 1961: 22%, 1961–1990: 48%, 1991–2000: 6%, 2001 or later: 24%. Older houses glow hotter.

Each house stands for one in ten of Regina's 69,170 houses (single-detached, semi-detached, row and duplex), drawn by when it was built. The glow shows the usual pattern: older houses tend to be leakier and less insulated. Snowfall scales with heating degree-days.

Why it matters in Regina

In the Regina area, 76% of households heat mainly with a forced-air furnace and about 10% with a boiler and radiators; natural gas is the main heating energy for 70% of households and electricity for 19% (Statistics Canada, 2023).

The risk rises after air sealing: a tighter house plus a strong exhaust fan or dryer can pull exhaust back down a chimney. That's why advisors test for spillage during an evaluation and why it should be repeated after serious tightening.

The CO alarm rule in Saskatchewan

Saskatchewan requires CO alarms in all residential buildings regardless of age (enforced since July 1, 2022), and from November 1, 2026, 'Henry's Law' requires one in every residential suite, including secondary suites.

What the check involves

  • Worst-case depressurization: exhaust fans and the dryer on, doors set to make the appliance room as negative as it gets.
  • A spillage and draft check at each appliance, with a CO reading.
  • A plan if anything fails: often a sealed-combustion appliance or a fix to the venting, done by a licensed gas or oil technician.

Alarms warn you once CO is already in the house. A spillage test finds a venting problem before it produces CO.
