Best/easiest way is to use a modular time delay relay. Go to
www.rswww.com and search for part number 300 - 6045.

This is a variable off delay timer/relay. Cost = £35.00 but is all
you need except for a bit of din rail to mount it on.

... and a box to enclose the terminals?


I thought he had the boxology to start with but maybe he didn't.

How much is a pipe stat and a metre or two of heat resistant 4 core? I
think you'd have more than £15 of change from that £35... A pipe stat
will work better as well, the pump will only run on for as long (or a
short) as is required.

Hmm, OK.

But if the pipeology is cold to start with how will the pump ever get to
know when to start?
