The short answer: once a year, before winter
For the majority of Tasmanian households, a professional clean every 12 months is the right rhythm. It clears the season's creosote build-up, picks up any blockages, and gives you a clean start before the cold sets in.
Booking in late summer or early autumn is ideal — it's before the pre-winter rush and means your heater is ready the first cold night you need it.
When you may need it more often
A six-monthly clean is worth considering if you:
- Run the heater all day, every day through winter.
- Burn unseasoned, green, or damp firewood.
- Live in a cooler area where the heater is rarely off.
- Damp the heater right down overnight, every night.
- Have noticed smoke, smell, or a slow draw.
These habits all encourage creosote — the dark, tar-like residue that builds up in the flue and is the main fuel behind chimney fires.
Open fireplaces vs wood heaters
Open fireplaces produce more soot per hour of burn and benefit from being checked once a year even with light use. Modern enclosed wood heaters burn cleaner but their flues still need annual servicing to catch creosote and rule out blockages.
If it's been more than a year — don't guess
If you can't remember the last clean, treat it as overdue. A short visit gives you a clear picture of what's happening inside the flue, and lets you light a fire on the coldest Tasmanian night with confidence.
A note on safety: chimney and flue issues can become serious quickly. When in doubt, leave the heater unlit and call a qualified sweep — a short visit beats guessing.
