Combustion safety testing in Winnipeg

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 Winnipeg area, the main heating energy is natural gas for 56% of households.

How Winnipeg is built

Winnipeg's houses by when they were built Ten house shapes, one for each tenth of Winnipeg's 202,915 houses. Before 1961: 37%, 1961–1990: 40%, 1991–2000: 6%, 2001 or later: 17%. Older houses glow hotter.

Each house stands for one in ten of Winnipeg's 202,915 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 Winnipeg

In the Winnipeg area, 66% of households heat mainly with a forced-air furnace, 12% with electric baseboards and about 7% with a boiler and radiators; natural gas is the main heating energy for 56% of households and electricity for 27% (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 Manitoba

Manitoba's Fire Code requires CO detection only in buildings subject to fire-safety inspections, not in ordinary private homes, so installing alarms is up to you.

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.

Who does combustion safety testing?

Energy advisors check for spillage during an EnerGuide evaluation. Repairs to venting or appliances are done by a licensed gas or oil technician.

I have CO alarms. Isn't that enough?

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