Nothing quite as awe-inspiring as some of the ideas on here, but I have been insulating my hoses for about 4 years with this stuff: http://www.pipelagging.com/12mm-solar-pipe-insulation-high-temperature-150c-uv-resistant-external-use-13mm#.UtMlAc4gGSM

I'm still yet to have hoses freeze up on me.

Hi Ian

Here's the ebay item number: 181301237211

Not my usual supplier but an identical unit, in addition to this I recommend overing the tank with a "Life Blanket" available from Amazon.

Hope this helps

John
