FAQ
1. Do I need a chimney liner for my wood-burning stove?
Yes. A chimney liner improves safety, enhances stove performance, reduces creosote buildup, and helps protect the chimney structure. Most modern stove installations require a suitable liner.
2. Why should my chimney be swept before installing a liner?
Sweeping removes soot, creosote, nests, and debris, allowing the liner to be installed safely and ensuring the chimney can be properly inspected.
3. How often should my chimney be swept?
Wood-burning appliances should typically be swept at least once a year, or more frequently if used heavily.
4. How long does a chimney liner last?
A quality stainless steel liner can last between 15 and 30 years, depending on fuel quality, maintenance, and usage.
5. What size chimney liner do I need?
The liner should match your stove manufacturer’s recommended flue size, commonly 5-inch or 6-inch for domestic wood-burning stoves.
6. Can I install a wood-burning stove without a chimney?
Yes. A twin-wall insulated flue system can be installed through the roof or an external wall where no chimney exists.
7. Do I need planning permission?
Most installations do not require planning permission, although listed buildings and conservation areas may have additional requirements.
8. Do I need Building Regulations approval?
Yes. All installations must comply with local building regulations and should be certified by a qualified installer where required.
9. Can I install my own stove?
While possible in some areas, professional installation is strongly recommended to ensure safety and compliance.
10. Why is my stove smoking into the room?
Poor chimney draft, a blocked flue, damp fuel, or insufficient ventilation are common causes.
11. What is creosote?
Creosote is a highly flammable tar-like substance that forms when wood burns inefficiently.
12. How can I reduce creosote buildup?
Burn only seasoned or kiln-dried wood, maintain good airflow, and have the chimney swept regularly.
13. What moisture content should firewood have?
Below 20% moisture content is recommended for efficient burning.
14. Can I burn treated or painted wood?
No. Treated, painted, or manufactured wood releases harmful chemicals and can damage your stove.
15. What’s the difference between seasoned and kiln-dried logs?
Kiln-dried logs have lower moisture content and provide cleaner, more efficient combustion.
16. What type of chimney liner is best?
For most existing masonry chimneys, a stainless steel flexible liner is the preferred option.
17. Should my chimney liner be insulated?
Insulation improves draft, reduces condensation, and can extend the life of the liner.
18. What causes chimney downdraught?
Wind direction, chimney height, nearby buildings, or trees can all contribute.
19. What is a chimney cowl?
A chimney cowl helps prevent rain, birds, debris, and downdraught from entering the chimney.
20. Why does my chimney smell?
Creosote buildup, damp conditions, or poor ventilation are common causes.
21. Can birds nest in chimneys?
Yes. Chimneys should be capped or fitted with a bird guard where appropriate.
22. How long does stove installation take?
Most installations are completed within one day, although more complex projects may take longer.
23. Can a stove heat my whole house?
Some larger stoves or boiler stoves can heat multiple rooms or your central heating system.
24. What size stove do I need?
The correct output depends on room size, insulation, and heat loss calculations.
25. How efficient are wood-burning stoves?
Modern Ecodesign stoves can achieve efficiencies above 75%.
26. What is an Ecodesign stove?
An Ecodesign stove meets strict emissions and efficiency standards for cleaner burning.
27. Can I burn coal in a wood-burning stove?
Only if the stove is specifically designed as a multi-fuel appliance.
28. What’s the difference between wood-burning and multi-fuel stoves?
Wood-burning stoves are designed for logs, while multi-fuel stoves can also burn approved smokeless fuels.
29. Why won’t my fire stay lit?
Wet wood, poor airflow, blocked flues, or inadequate chimney draft are common reasons.
30. Should I leave the stove door open?
Only while lighting the fire. Once established, the door should remain closed.
31. How often should I empty the ash?
Remove excess ash regularly while leaving a thin layer to help insulate the firebed.
32. Can I use my existing fireplace opening?
In many cases yes, although alterations may be needed for safety and compliance.
33. What is a register plate?
A register plate seals the chimney opening above the stove, improving efficiency and preventing soot from falling.
34. Do I need a hearth?
Yes. Every stove requires a suitable non-combustible hearth that meets current regulations.
35. What material is best for a hearth?
Slate, granite, glass, porcelain, and concrete are all popular choices.
36. Can I install a stove in a conservatory?
Yes, provided all regulations regarding ventilation and clearances are met.
37. Do I need ventilation?
Some stoves require a dedicated air vent depending on their output and property characteristics.
38. What is a carbon monoxide alarm?
A safety device that detects carbon monoxide gas and should be installed near every solid fuel appliance.
39. Where should a carbon monoxide alarm be fitted?
Follow the manufacturer’s instructions, typically in the same room as the stove and at an appropriate height and distance.
40. Can I decorate around my fireplace?
Yes, but only with heat-resistant materials where required and maintaining safe clearances.
41. How often should my stove be serviced?
Annually, ideally before the heating season.
42. Why is my stove glass turning black?
Wet wood, poor airflow, or burning at low temperatures are common causes.
43. Can cracked stove glass be repaired?
No. Cracked glass should always be replaced.
44. What causes chimney fires?
Creosote deposits igniting inside the chimney due to excessive buildup.
45. How do I know if my chimney liner is damaged?
Signs include poor draft, smoke leakage, excessive soot, and visible damage during inspection.
46. Can I use my stove during a power cut?
Yes. Most wood-burning stoves operate independently of electricity.
47. Is a wood-burning stove environmentally friendly?
Modern Ecodesign stoves burning properly seasoned wood produce significantly lower emissions than older appliances.
48. How much does a stove installation cost?
Costs vary depending on the stove, flue requirements, chimney condition, and installation complexity.
49. What guarantees come with a chimney liner?
Most quality stainless steel liners include manufacturer warranties when installed according to the manufacturer’s instructions.
50. Why should I choose a professional installer?
A qualified installer ensures your fireplace or stove is safe, compliant with regulations, performs efficiently, and is correctly certified where applicable.
