Not likely. A poor ground connection would resist the flow of current,
not increase it, so fuse wouldn't blow.

I'm not seeing any advantage to splitting the circuits unless you simply
want the other devices on the fuse to continue to work after the heater
blows the fuse again. The circuit isn't a marginal one where the fuse is
almost big enough so that it is on the verge of blowing all the time. A
blowing fuse there indicates that something Bad has happened which
could, like, start a fire or something. This is exactly what a fuse does
for a living.
