Hello All,

I'm a bit of a diy n00b, but I can at least change a fuse. So I felt a
bit foolish paying a central heating engineer £65 to get my heating
re-started when the problem turned out to by a dead 3amp fuse in the
mains socket that the boiler programmer (Potterton EP2001) was
connected too.

However since he first visited in late December I have since woken up
on three separate mornings to find the house cold, and fuse blown
again.

Can anyone advise as to what is likely to be the cause of the fuses
blowing?

You have an intermittent short circuit somewhere in your heating equipment
or wiring. I would start by looking at the pump - 'cos that's where water
and electrics come closest to each other.
