I have an electric fire suite,which we love,but recently we are experiencing a terrible vibration from it.You can feel it very badly through the floor and it causes vases etc to rattle on tables etc.It is caused by the fan in the convector heater within the suite.I have tried to tighten etc,but cant tighten any more.I have terminal cancer and cant do without my fire as I get cold even in the summer(whats that ha ha) sometimes.Has anyone else came accross this same problem and if so how did you remedy it?
