I also live (right) on the South coast, HOWEVER if you leave a small amount of water anywhere in the system it is MORE likely to freeze than a large volume (it gives up its heat "energy" much quicker due to having a high surface area to volume ratio) so even a short period of sub zero temperature can freeze it and cause damage.
Small quantities will rest at the lowest points of pipes and/or the base of water pumps etc. (Dont forget the toilet flush tank, if fitted, will have a small pump right at the base that can be very vulnerable to freezing)
I drain the boiler, then open all the taps, once water has stopped running, close all the taps and blow air through each of the taps in turn starting at the furthest from the boiler (usually the shower) its amazing just how much more water is expelled by that means !!!!
I then leave all the taps open.
Dont forget to remove any glass jars/bottles because they break if they freeze!! (Lesson learnt the hard way!)
Its not the destination that matters.
It's who you share the journey with (even if like me, it’s in a caravan!)
I am very fortunate to have Mrs Plodd to share mine with
