Protecting One's Assets

I think you've mis-read the output Andrew. I've just put 20 watts for 24 hours into the calculator for which you provided the link, and the answer was 7,3 Pence (not pounds).
7,3 pence x 7 days x 20 weeks = about £10
And that protects my lathe and my pillar drill - well worth it.

0.03 x 14 x24 = 10.08 PENCE per day however you else may calculate it :scratch:
NOT £11 per day as as was stated above

--- Quote ---I use a 12 volt halogen light with a computer heatsink stuck to it in the bottom of a small fridge , it works a treat no rust last winter and if I drop a 6" chuck and smash the light its only 12volt .

That's a really good idea - up-cycling a defunct fridge into a heated cupboard for tools and such. I like it a lot.
As for peltier elements - I would avoid them for this sort of application. Peltier refrigerators have two advantages, firstly no moving parts (simple, light, rugged, maintenance free), secondly they can be run off standard 12 Volt or 24 Volt vehicle supplies. The MoD use such fridges for a couple of specialised battlefield applications. The down side is that they are very inefficient.
£10 for four months worth of electrickery is certainly a bargain.

The UK supply of trace heating cable is 3\4 of a mile from me , a chat with the boss man he said that iff the end caps were fitted corectly and sealed with silicon rubber it can be used under water but not permonantly , there is two types of cable self regulating and non regulating which needs a thermastat , I have it taped to the under side of my mill oil tray with a layer of insulation under , and a stat on top it comes on at 9 degrees celcius and it has to be realy cold to stay on very long usualy on for ten minutes and off for five .

For dehumidifying you could use silica gel or something similar. You can get the kind with cobalt chloride in it that turns pink when exhausted. Then you can dry it out in the oven.
