Outside piping frost

[Gasmanjack]

Has anyone any experience of fitting electrical heating tape or wrapping round outside cold water piping? Would you recomend any particular system?
Thanks in advance.

Used by many farmers. I have used it. Follow the guidelines and your external water supply pipes will not freeze. Use Nylon/Plastic where possible.
