Well, the Sealey heater arrived and it's nothing like the picture.
It looks like this-
So I gutted it and I'm building the guts into the van under the seat, with a rectangular vent cut out of the front board behind the fold out bed leg and a grill fitted over it.
I've hard wired it to 700W (the low setting) and have an on/off switch behind the bed leg so you have to fold it out to turn on the heater.
The bed leg protects the grill from being kicked while the bed is in the upright position.
I wouldn't recommend you do this if you're not familiar with mains wiring and thermal conductivity.
But if you do, be careful how you mount it as the element fins are live so need protection from inadvertent wife's fingers/dogs noses.
Ditto on the inside under the bed, you need to provide protection from anything metal or combustible stored under there coming in contact with the live parts while still providing enough airflow for the fan.
I wouldn't use the 1400W setting as the bed boards would get pretty hot.
700W seems fine for taking the chill off, the fan is not too loud and I'm pretty pleased with it.
A few nights on Mull will prove it.
