There are three basic ways of burning wood.
The simplest is logs. Easy to get hold of and if you get a tree, branch or whatever, possible to process yourself.
The next two, woodchip and pellet, are usually called biomass. They can be automated so that there is a constant feed in.
Woodchip is the next simplest. You need to match the size of the chips to the boiler or it will clog. They must be stored dry or they will clog. You either have a suitable chipper yourself, which is rather expensive, or more usually get someone in for a day or so a year.
Pellet. The pellets have to be produced by fairly hefty machinery, although you could probably make some sort of heath robinson set up yourself if you really tried. You buy them in by the plastic sack or lorry load and have to store them. They usually go into a hopper and gravity feed into the boiler.
Logs use the least energy to produce, are easy to deal with and you can do them yourself. Woodchip is the next, and pellets are the worst for energy use to produce and you are tied into a supplier. Watch where they come from too as some are imported from the Far East.
Hope that helps. Any other questions on logs or biomass, just ask. |

What should go with for CH and heating water - Multi fuel Boiler stove or Bios mass boiler? |
