I got this patio heater about a year ago:- Please login (registration is free!) to view this link. Its been working fine with no issues what so ever, until 2 days ago. The heater is plugged in via a 10m extension cable, as its always been. Two days ago i had it on and then about 15 mins later it just cut out, it was on the lowest setting. Naturally i thought either the heater or the extension had blown a fuse. But what iv found out is that the extension cable doesnt seem to work anymore and when i plug the heater in anywhere else is just trips the household fuse for all the sockets in the house. The worst thing is that it isnt even switched ON when it trips the fuse, its just simply plugged in a pop it goes. The first time i plugged it in i did see a bright flash from the plug so i went and changed the 13 amp fuse, but it still keeps doing it. Any ideas why its gone so bad???
