OK,
Have given up on any idea of any kind of solar central heating.
Got a bloke round to quote for a Sorba with back boiler and pump, which seems ok, but what I want to know is, what is the cost of wood, hard or softwood and how much would an "average" sized Sorba use in a winter from say end October to start June?? Would Charcoal be more efficient as per cost or is Turkish coal viable??
Any advice gratefully received.
