The glow shows the usual pattern: older houses tend to be leakier and less insulated. Snowfall scales with heating degree-days.

What a CO check involves

  • Alarms next to sleeping areas and on every storey, tested monthly and replaced by their end-of-life date (usually 7 to 10 years).
  • Annual service of fuel-burning appliances by a licensed technician.
  • A combustion spillage test during an energy evaluation, which catches a venting problem before it produces CO.
