Best wood in terms of size and type for Helios multi-fuel termocamino

Split wood will be easier, but more expensive (if you can source un-split wood that is...). Split from the ferramentas here comes in 25cm, 33cm and 50cm, think 50cm would suit, but look at the manual for Helios. Using a wood burning stove we have found Beech (Faggio) best for starting off and then Oak (Quercia) later, we probably burn 2:1 Beech/Oak.

Ask around locally as to which wood supplier your neighbours would recommend. Many do not advertise and rely on word of mouth. Mention your contact's name and you are less likely to be fobbed off with poor quality wood. They will supply the local wood and will usually cut it to your specfications. We have found oak and hornbeam (carpino) to be the best - both seem to be in abundant supply.

I burn anything I can get my hands on, old pallets go well!

Be careful where you buy around here Rachel...the "largest" supplier has a reputation for cheating on quantity.  Often, if you get the wood delivered (which is the only way to do it unless you just fill the boot of a car) he sends it out without the print off that shows the actual weight loaded...
