Fuels for Open Fireplaces – What’s Best?
As HETAS-approved chimney specialists serving Cambridge and surrounding areas, we regularly advise homeowners about the best fuel choices for their open fireplaces. The decision extends beyond simply choosing between wood and coal, particularly given Cambridgeshire’s mix of period properties and conservation areas.
Understanding Your Options
Your fuel choice depends on several factors:
- Your chimney liner type
- Local smoke control regulations
- Property type and age
- Desired heating efficiency
Wood Fuel Options
Kiln-Dried Wood: The Premium Choice
Professional chimney sweeps in Cambridge recommend kiln-dried wood because:
- Moisture content between 10-20%
- Triple the heat output of unseasoned wood
- Minimal spitting, protecting period property floors
- Reduced chimney deposits
- Cleaner burning
Properly Seasoned Wood
According to HETAS guidelines and our experience as certified chimney sweeps across Cambridgeshire:
- Requires 2-3 years minimum seasoning
- Must reach below 20% moisture content
- Proper storage essential in our damp climate
- Regular moisture testing recommended
Part-Seasoned Wood: A Note of Caution
When conducting chimney inspections in Cambridge properties, we often find issues caused by partially seasoned wood:
- Typically only dried for 1-2 years
- Requires additional seasoning time
- Not suitable for immediate use
- Can cause dangerous creosote buildup
Coal Options for Open Fireplaces
Traditional House Coal
Suitable for most traditional fireplaces in Cambridge’s period properties:
- High heat output
- Long-burning characteristics
- Compatible with most liner types
- Often used as base fuel
Smokeless Coal Requirements
Essential knowledge for properties in Cambridge’s smoke control areas:
- Meets clean air regulations
- Requires specific liner compatibility
- Higher burning temperature
- Different handling requirements
Understanding Smoke Control Zones
Many areas within Cambridge and surrounding towns fall under smoke control regulations. Our local chimney cleaning services regularly assist homeowners in:
- Checking property restrictions
- Understanding fuel limitations
- Ensuring compliance
- Maintaining proper documentation
