What do the figures mean?
Calorific value is the heat one kilogram gives, in kilocalories. Moisture is the water left in the pellets. Ash is what stays behind after burning.
Pellets for boilers built for coal.
Rice husk, mustard husk, groundnut shell and wheat straw pellets, each with its figures below. Burn a sample in your own boiler, and we will call you with a price.

What the same heat costs
Fill in the three figures to compare.
This compares heat alone; how well a boiler burns each fuel also counts.
Switching from coal or firewood
Boilers and furnaces built for coal and firewood can run on pellets instead. Keep the pellets under cover: they take up water and crumble when wet.
