Don't let it go above 22 or you will shorten the life of the tube. Get to poundland and buy 2-3 of the aluminium bottles in the camping section. Fill them with water and chuck in the freezer. Use 2 when the water is at 18 and top up as needed.

even better .. I re use the 2l bottles thet you get the cheap lemonaid or coke in ! ... even if you don't drink it, it's cheaper than £1 !

I'm currently looking at used freezers on ebay ,,, seems like £20 is average which seems like a no brainer,

Next thing is coolant.

Laser manual says water and replace every week

I'm thinking car antifreeze ??? what do you think about that ?

Remember , in the winter... temps drop below Z in the work shop !
