Product details:

  • Pale yellow colour;
  • Calorific value: 18.0 MJ/kg (5.0 kWh/kg);
  • Each briquette measures approximately 65mm x 90mm x 150mm (approx. 2.5 x 3.5 x 6 in.);
  • Each 10kg pack contains 12 heat logs fitted into traditional PE bag

Use recommendations:

Two to three briquettes should be used to start the fire. Because they burn much hotter than logs and expand slightly in the fire, it is important not to overload your fire box. 

To maximise performance, get the fire really hot before turning down the air flow and refuelling as required. 

Recommended for smaller wood and multi-fuel stoves and log boilers. For larger appliances, we recommend Nestro Round Wood Briquettes due to the larger size of the individual briquette. 


Product Highlights:

  • Made of 100% clean virgin Pine & Spruce sawdust
  • Low moisture: 4.5% only
  • Low ash: 0.7%
  • High calorific value: 18.0 MJ/kg (5.0 kWh/kg)
  • Long burning time up to 3.5 hours
  • Woodsure ® Ready to Burn Approved: WS356
  • 21% lower cost of heat released compared to Pini-Kay Briquettes
  • Uniform, smooth surface, light colour wood
  • Recommended for smaller stoves


Due to very low moisture levels (approx. 4.5% compared to 20% in kiln-dried logs and 30% in seasoned logs), the Classic Heat Logs light easily and give off a lot of heat. In our tests, they produced a nice burn of approx. 45min followed by up to two hours of hot "glow". The duration of burning will depend on the quantity loaded and burn intensity regulated by air inflow settings.
