It comes from a shared communal heating system. The issue is one of 3 apartments that it provides heat for and the person died in one of them and in the other nobody really lives there they just go there to lay there head and then they are off again for months. I am in the 3rd apartment and the heat is not reaching my property because the other two apartments are empty so a huge air lock has developed and there is nobody there to rectify it and the workmen can't get access. Its really shoddy plumbing this shouldn't happen but the problem with the Council is that they don't want to spend money, they cheap out doing things the cheapest way possible but then they have to spend more money correcting problems because things were never done properly in the first place.
