In answer to my own question, they burn rather hot indeed once going properly.

They’re these ones Bord na Mona and were £5 for 20 blocks. Think they’ll do the job in (first world) emergencies!

I used to cut and burn peat in Orkney. It gave out a ferocious heat and an awesome smell.

£5 for twenty blocks 😯 My peat bank could have been more profitable than a gold mine.

We are getting a log burner fitted in two weeks time. Does anybody know of a good trusted log supplier in the south Lancashire or Merseyside area. As previously mentioned on the thread I’m a little concerned about people felling a tree and selling it to me the next day as seasoned logs!
