Whats every ones thoughts on this wood chip?

Good stuff for chip burners?

Shredded pallets?

Could be a problem with binding together and bridging in the hopper above the auger as it won't flow very well, could be almost too dry for some systems.

Yeah, shredded pallets.

Came across on youtube.

Its a machine made by HEIZOHACK.

 

I didn't think the stuff looked good, but it must be alright if they say so....?

If you use that wood chip you will be very sorry. It will take some shovelling out as it won't go through your system.

As said by (Niel I believe )use dry chip or it will rot. Aim for 20%mc

Hire a good quality biomass chipper such as heizohack or muzmax.

Chipping brash can be difficult with these chippers though as the twigs can go through the screens

There is no way that product has been produced by a heizohack chipper.

 

Would suggest its this pile of junk.

Yeah that's the one Renewaljohn, it's on the Fuelwood website as well.

This isn't a Heizohack?

 

Slow way to make wood chip......and bad quality chip at that

[renewablejohn]

Its not the quality of chip I am concerned with as very few boilers will be capable of using it as is. The problem comes when it is reprocessed into wood pellets and sold as first class pellets eligible for RHI which clearly its not as the timber source is normally recycled pallets or demolition timber.
