Appliance recommendation:

Recommended for all wood burning stoves and conventional open fires and outdoor chimneys. Use modern and preferably Eco-Design labelled appliances


WillowWarm Carbon Neutral Briquettes burn clean and contain less ash and less moisture:

  • Less ash means less cleaning and higher energy efficiency;
  • Dried fuel with low moisture gives more heat per unit burned;
  • Dried fuel causes less chimney fouling;
  • Dried fuel promotes clean combustion;
  • Dried fuel provides the most consistent operating cost as no energy is used to evaporate water in the fuel.

How to achieve the best results? 

  • Always store WillowWarm Carbon Neutral Briquettes in a dry location away from the stove or open fire;
  • Never leave an open fire without a spark guard;
  • Always ensure that the stove or fireplace has adequate ventilation for safe combustion;
  • Regularly maintain your chimney and have it cleaned by a proper chimney sweep;
  • Use WillowWarm Carbon Neutral Briquettes with high efficiency air regulated stoves and open fires fitted with a flue


  • Always have your stove or fireplace maintained by a qualified technician.

Usage recommendations:

Burning time in different appliances will depend on air inflow setting, number of briquettes loaded, outside temperature, and size of appliance and can range anywhere from 1 hour to over 3 hours. A minimum of three to four briquettes should be loaded at any given time. Due to particularly low moisture it's important to adjust air inflow to ensure longest possible burning and glowing time.

Suitable for modern wood stoves with adjustable air inflow, woodburning cookers, barbecues, chimeneas. Results in open fireplaces will depend on air inflow. 

Heat release time:

In our tests the briquettes produced good flame during the first 30 minutes of burning and then glowed for over 2.5 hours giving a steady heat until reduction to a small amount of grey ash residue. Total heat release time was reported at over 3 hours.
