Pellet or wood chips? We help you decide
One of our customers' most common questions is whether they should think in terms of a pellet or wood chip boiler. Our answer is almost always a counter-question: how much space do you have, and how close is the nearest reliable supplier?
In favor of pellets
Pellets are a standardized, pressed product: their energy density is high, their quality is predictable, and their dosing is precise. They fit in a smaller space, can be fed from a silo or from bagged packaging, and from the boiler's perspective, they are the most convenient solid fuel. On an urban site, in a smaller workshop, for a demand of around 20-100 kW, pellets are most often the practical choice.
The KWB Easyfire and Multifire, Hargassner or Guntamatic pellet boilers passing through our warehouse are available in both domestic and small industrial sizes, with automatic cleaning and ignition, so they require practically no daily intervention.
The arguments in favor of wood chips
Wood chips win where quantity matters. In the case of larger halls, dryers, greenhouses, or district heating-type applications, their cost advantage per kilowatt-hour is unbeatable, provided there is space for storage and mechanical loading. Above one hundred kilowatts, on a rural site, wood chips are almost always the more economical choice.
Many plants, by the way, choose a mixed solution: a boiler that handles both fuels. The KWB Multifire model name is no coincidence: both pellets and wood chips can go into it, so the owner can always heat with the material that is currently cheaper or more available.
If you write to us about the size of the area you would like to heat and what is available at your site, we will suggest a specific machine and fuel calculation for it, even on the very same day.
