I was just sitting down watching tv when a big spark followed by crackling noise from the heater and embers flew out!! scared the life out of me , I hardley ever use them as since Ive been living here the plug switch's tend to spark.My landlord knew about the sparking and as soon as this happened today I called him straight over, hes just left and said its something to do with the wires touching ?? hes turned it back on and said to call him or let him know if anything happens. Apparently not a big deal :s Im nearly 8 months preg and petrified of fire, two in hand , not a good combo haha please give me your opinions as to what I should do as Im not sure about these things , Thank you
