Why heater service matters up here
The upper Mountains are higher and colder than the lower Mountains. Frost is common and heaters can run for months. A heater that goes that long without a check can develop faults, including ones that produce carbon monoxide.
Carbon monoxide has no smell, no colour and no taste. A blocked flue or a badly burning heater can release it into the room. Early signs include headaches, tiredness, nausea and feeling worse at home than out. If anyone feels unwell, turn the heater off, get outside into fresh air and call 000.
What a gas heater service usually covers
The exact steps depend on the heater. A licensed gasfitter will typically look at:
- The burner and flame, including colour and shape.
- The flue or vent, checking it is clear and sound.
- Gas connections and hoses for leaks and wear.
- The pilot or ignition system.
- Safety devices on the heater.
- Ventilation in the room.
- Signs of soot, scorch marks or rust around the unit.
If something is wrong, the gasfitter will tell you what, why and what the options are. Some heaters can be repaired. Some are better replaced. A heater that is old or unsafe may be switched off until the problem is fixed.
Carbon monoxide testing
Ask whether a carbon monoxide test is included when you book. A battery carbon monoxide alarm is a useful backup, but it does not replace a service.
Which heaters
- Flued wall and floor heaters, mains or LPG.
- Ducted gas heating.
- Unflued portable gas heaters. These are a particular concern in sealed, draught-proofed rooms.
- Gas log fires and decorative fires.
Mention the make and age of your heater when you call. It helps the gasfitter plan.
Mains and LPG
Heaters on mains gas and on LPG are serviced in much the same way. On LPG, the regulator and hose between the bottle and the house get a look too. See LPG bottle leaks for more.
When to book
Book before the first cold snap. Early autumn is a good time. A heater you have not used since September deserves a check before you light it for the season.
Old houses, tight rooms
Older Mountains cottages often have a heater in a small lounge room, with draughts sealed up to keep the warmth in. Good ventilation matters. A heater that was fine in a draughty house can become a problem after new insulation, new windows or a closed-up fireplace. Tell the gasfitter about any changes.
Cost
Prices depend on the heater type and what needs doing. Ask for a quote before work starts.

Common questions
How often should a gas heater be serviced?
Follow the maker's advice. A check every year or two, before winter, is a sensible habit for a heater in regular use.
Does a gas heater service include a leak check?
A licensed gasfitter will normally check connections as part of a service. Confirm when you book.
Is an unflued gas heater safe?
They can be used safely with correct ventilation, but they put combustion products into the room. Have them checked, and never run one in a sealed room.
What are the signs of carbon monoxide?
Headaches, drowsiness, nausea and feeling better when you leave the house. Turn the heater off, get outside into fresh air and call 000 if anyone feels unwell.
Can LPG heaters be serviced?
Yes. Ask for the regulator and hose to be checked too.
What does a heater service cost?
It depends on the heater and what is found. Ask for a quote before work starts.
