Combustion safety testing in Charlottetown

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 Prince Edward Island, the main heating energy is oil for 28% and wood for 8% of households.

How Charlottetown is built

Charlottetown's houses by when they were built Ten house shapes, one for each tenth of Charlottetown's 10,405 houses. Before 1961: 20%, 1961–1990: 46%, 1991–2000: 12%, 2001 or later: 22%. Older houses glow hotter.

Each house stands for one in ten of Charlottetown's 10,405 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. More snow in the drawing means more heating degree-days: a longer, colder heating season.

Why it matters in Charlottetown

In Prince Edward Island, 36% of households heat mainly with a heat pump, 16% with a boiler and radiators, 14% with a forced-air furnace and 10% with electric baseboards; oil is the main heating energy for 28% of households, electricity for 18% and wood for 8% (Statistics Canada, 2023).

Charlottetown has no piped natural gas for homes, so combustion appliances here are mostly oil, propane or wood, and each needs its own venting check.

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 Prince Edward Island

PEI's Fire Marshal advises CO alarms outside each sleeping area and on every level, but we found no rule requiring them in existing homes.

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.

What this means in Charlottetown’s climate

Damp, windy, icy winters and costly oil: switch to heat pumps, seal, test for radon.

Why it matters here: Checks that the oil burner and chimney vent safely, especially once air sealing changes indoor air pressure.

Best timing: Before winter, and again after air sealing.

  • Plan your move off oil. Oil prices rose 65% to 81% in a year, and corrosion is a leading cause of oil tank leaks. Cold-climate heat pumps can be up to three times as efficient as oil heating. Ask: Ask the advisor to note your oil tank's age and condition, and to size a cold-climate heat pump with a backup plan.

PEI's Fire Marshal advises CO alarms outside each sleeping area and on every level, but we found no rule requiring them in existing homes.

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.
