I cannot speak for all parts of Bulgaria, but I think that most would agree that in South East Bulgaria, that the weather has been fairly mild so far and a lot of you have not used as much firewood as in other winters.
As this is my first winter in the new house as opposed to being in a caravan for the last one, I am still learning how best to regulate my 'Petchka' which also provides me with hot water (in addition to an electric immersion heater element). Being in an ECO house, I don't usually light the fire until around 5-6pm and my wood supplies are my own cut Plum tree and Willow some of which has not had time to dry out completely as it should have, but it is free except for the cost of my chainsaw fuel and maintenance.
I use about a small sackful of chopped wood per evening minimum and the fire is always going out or gone out by around midnight, but this is enough to warm/heat the house depending on outside temperature. I'm just wondering how much wood (in sackfuls as opposed to cubic metres) you use to keep your house heated on a typical day. Do you keep your home fire burning 24/7 or just light it as required? Just trying to get a measure for next winter on how much wood I might require on a daily basis.
I understand that there are numerous factors to take into account and that it might be perceived as a general how long is a piece of string question, but just trying to get some rough idea.
