13A fuses for 16A immersions?
45A DP switches - wouldnt 20A DP do and be a bit cheaper?

The 13amp fuses might well last for months, but none the less they are not
appropriate, nor is the spur unit rated at 16amp.

Two separate circuits from the DB would be a better way to it, each rated
at 16 or 20amp. Failing that, a 2way DB mounted at the far end of the
32amp feed, with a 20amp rated DP switch for control.

The OP will have to have a look and see what the "one circuit" that feeds
the heaters consists of. I do like the idea of a 2 way CU at the far end of
the circuit if it is a 4mm or 6mm supply.
