Safety boundary: Never place an unapproved gas burner or improvised electric heater in an existing fireplace.
Start with the objective
Decide whether the priority is heat, appearance, convenience, backup capability or reduced maintenance.
Gas options
A certified gas insert, fireplace or log set has specific requirements. Some decorative log sets provide little heat and may rely on an existing chimney.
Electric options
Electric inserts simplify combustion and venting concerns but still need suitable electrical supply and clearances.
Inspect the existing structure
The chimney, hearth, firebox and surrounding finishes should be evaluated before selecting equipment. Quotes should identify what remains and what is permanently altered.
Useful questions to record
- What appliance type and venting arrangement is installed?
- Does the issue involve controls, ignition, soot, odour or glass?
- Has the unit been inspected recently?
