For my two solid fuel stoves at home, [Please dont tell London Mayor] I burn wood logs. What else would they be made off. I pay £285 for 1.25 ton delivered to my door. This keeps both stoves going all winter, not 24/7, most evenings only. The smaller logs get transported to Hawthorn to keep her warm through the winter. With some smokeless to keep it in overnight. At a rough estimate it costs me around £350 per year to run three stoves. To my mind its money well spent. We are toasty at home and on the boat.
