Which is the best fuse to use (3A, 5A or 13A) with a 1.15kW electric fire at a potential difference of 240v
1150/240=4.79 so theoretically a 5A fuse shoud do.

May be 5A will do, as "cold" heater element resistance would be higher than normal heating.
But according to regulations in the UK on changing fuses it should be either a 3A for below 720W or a 13amp for above 720W .
