Wood stove at an empty cottage: never count on it
Updated
The wood stove is the heart of the cottage: the Friday-night fire, the heat that fills the room in minutes, the calm when the power’s out. But on Sunday, when you lock up for the week, it can’t do a thing for the house. An empty cottage in winter has to be protected by heat that runs with nobody there.
What to do before you leave the cottage
1. Let the fire burn out completely before you go
Never leave with a fire burning, even banked low, even with the door shut. Stop adding wood well before you leave and make sure there’s no flame left.
2. Treat ashes as if they’re still hot
Embers can stay hot for a long time. Québec.ca asks you to empty ashes into a metal container with a raised bottom and a metal lid, set outside on a non-combustible surface at least a metre from anything else — the house, the deck, the woodpile — and to wait at least seven days before emptying it anywhere. Never in a garbage bin, a bag or a cardboard box.
3. Confirm the main heat is on
Before closing the door, make sure the baseboards, furnace or heat pump are actually heating, at the setting your plumber or insurer recommends. That’s the heat protecting the house through the week — not the stove.
4. Close the damper or air intake as the manufacturer says
Once the fire is completely out and cold, follow the stove manufacturer’s instructions for the air intake and, if there is one, the chimney damper. Don’t close anything while embers remain: carbon monoxide needs a way out.
5. Test the alarms
Press the test button on the smoke alarm and the carbon-monoxide alarm; Québec.ca recommends doing it monthly. Replace batteries as needed. A cottage where you burn wood needs both, with the carbon-monoxide alarm in the room holding the appliance and near the bedrooms.
Why you can’t count on a stove at an empty cottage
It doesn’t feed itself. A stove heats as long as someone loads it. Once the wood burns down, it cools, and so does the house. No wood stove can hold a temperature for days without someone feeding it.
A fire nobody’s watching is a fire risk. A log rolling against the glass, a door not latched, creosote igniting in the chimney: these happen when people are home too, but at an empty cottage nobody is there to react.
The heat is concentrated. A stove warms its own room very well and the basement, the back bathroom or the crawl space much less — which is exactly where the pipes that freeze tend to run.
The chimney works harder than you think. Damp wood and slow, smouldering fires encourage creosote. Québec.ca recommends having the chimney swept at least once a year, ideally in spring, and notes that no sweeping log or chemical additive replaces a professional sweep. At Townships cottages, where long weekend fires often burn wood off the property that isn’t always well seasoned, sweeping isn’t a detail.
Mountain realities. In Sutton, Potton and Abercorn, plenty of owners rely on the stove during Hydro-Québec outages. That’s a great plan when you’re there. When you’re in Montréal, the outage stops the main heat, and the stove is cold.
Your insurer may want to know. Tell your broker about the appliance — type, installation, sweeping — and keep proof of installation and maintenance. What gets asked varies from one insurer to the next.
Prevention: what you can do, and what belongs to the professionals
What an owner can do:
- Burn dry wood, stored under cover and away from the house.
- Have the chimney swept at least once a year by a qualified sweep, and keep the invoice.
- Keep a lidded metal ash container and an extinguisher within reach.
- Install and test smoke and carbon-monoxide alarms.
- Keep the chimney outlet and wall vents clear of snow.
What belongs to contractors and professionals:
- Installing or replacing a stove or chimney, following the manufacturer’s instructions and applicable rules.
- Checking the chimney and its joints after a chimney fire or a heavy-use winter.
- Adding reliable main heat where the stove was the only heat source (RBQ-licensed contractor, master electrician for the circuits).
In an empty house, how long before anyone notices?
If the main heat quits mid-week, the stove won’t change a thing: the house cools as if it didn’t have one. An outage, a tripped breaker, an empty propane tank, and the cold reaches the basement and exterior walls first. Nobody sees it until the next visit.
How often someone stops by sets how long a cottage can sit without heat before anyone knows. If your policy sets conditions for an unoccupied home, reread them or ask your broker: they vary from one insurer to the next.
What we look at on a visit
We don’t light the stove and we don’t touch it. Every visit, we read the main thermostat and compare it with the agreed setting, read the thermometer left in the coldest room, and check that the main heat is running. We check the indicator light and low-battery chirp on the smoke and carbon-monoxide alarms, and outside, that the wall exhaust vents are clear of snow.
If the heat isn’t holding or an alarm shows a problem, we call you the same day with photos, and bring in an RBQ-licensed contractor if needed. If there’s a smell of smoke or an alarm sounding, it’s 911 first.
