water freezing in the van tank / hose is easy to overcome, just put in a small oil filled rad
its the problem of the temps not getting much above 0 C
i had many days when the temps got above 0 C at about lunchtime, of course i couldnt work then as it was getting dark at 3.30 so the water i would have put down would have froze
it appeared many on here were struggling with the money issue, the answer is this summer when you can do a little more, just put a few quid away a week into either a seperate bank account or a sealed tin ( you can buy them for a few quid ) if we have a bad winter like this year, crack open the tin and you will have a few quid to pay the bills for a month
on a similar note, last year we decided to have a 2 quid coin tin, its the size of a baked bean tin and we decided to put only 2 quid coins in it ( our house rule was that you couldnt spend 2 quid coins ) , took us 5 months to fill, it had 304 quid in it
