buying a frost stat to keep freezer above freezing

[roys]

I like self regulating trace heating tape.  I have a 22mm that is prone to freezing, happened about 5 years ago in the first proper cold winter for a while, bit of a mess kitchen ceiling with a big bulge, fortunately for me I was about to do the kitchen up anyway.

The following year we had another big freeze but this time no damage because I had fitted 8 m of self regulating tape to it and a bit of pipe lagging.  That was the same year that plumbers were making lots of money disconnecting frozen drain pipe from condensing combi boilers as they had froze.
