this is what i dont understand about heating van . i wrap everthing up and yes pipes still freeze and since being water fed filter casings cracked twice. i dont heat the van as too heat it will cost a lot of money , and if pipes were frost free like mentioned above on way to work pipes would freeze ,
on the aspect of heated water system ok water hot in van but does it not freeze in pipe running along frozen ground , and then when it hits the glass does it not freeze on the glass.
in my oppinion raffer stay at home .
