Wooden Pini Kay briquettes are made of hard wood, pressed under extremely high pressure, without the use of glues, dyes and chemicals. They are characterized by their dark-brown color and hexagonal shape with a central hole, which incites combustion and with the effect of reaching a very high temperature in a short time.

Their use is suitable for all possible types of heaters, i.e. wood and coal boilers, open fireplaces and fireplace inserts, tiled stoves, etc. The highest calorific value can be achieved when burning Pini Kay briquettes in a wood gas boiler.
