Hi guys. After an ice cube maker, nothing massive, just enough for a few glasses of cocktails, whiskey etc. Can spend up to £80 or so.

Is this a one off or a regular thing? For me unless it is ver very frequent I'd just buy a couple of bags from the supermarket or get those polythene ice cube making bags.

I've got a fancy fridge that dispenses Ice but the cubes seem to melt quicker than the ice provided in pubs/bars, what is that all about?!

the drinks in pubs/bars are chilled? I find the ones in pubs/bars tend to melt much faster than the stuff from my freezer, especially if the mixer has been in fridge, and the spirit in the freezer.
 
Honestly it's better to just buy bagged ice in the long term.

Ice makers eat up a lot of electricity and take a lot of work, unless you throw a lot of parties and use it a lot it won't ever make up for the cost of buying and running it.
 
Buy a couple of trays, pop in some warm water and pop in freezer.

Wait to freeze, empty into a plastic bag in freezer.

rinse and repeat. Bag of ice cubes for whenever you need them :D
 
Not supposedly, it is correct. Freezing anything involves dropping the temperature of the item to below 0oC. THis is done by transferring the "heat" of the item out of the item. The bigger the differential the temperature is between the item and the environment (in this case a warm item and a cold freezer), the quicker this transfer takes place. As the differential becomes smaller (the temps of the environment and item become closer), the slower the transfer of heat.

Therefore if something is at 5oC (cold water), the transfer of heat is slower than if something is at, say, 20oC and the quicker the item will drop in temp.
 
I'm assuming hot water doesn't have copper in it like my mum told me when I was a kid as to why not to drink it. Although if your boiler is a tank based kind, couldnt it be oretty stagnant? Also it warms up your freezer more causing it to use more power?

I put supposedly because a) I've never tried it myself so can't say it was a definite and b) lots of discussions online about how it's not fully proven due to the that that frozen isn't fully defined by the Mpemba effect.

However, I wouldn't have posted it if I didn't feel that it was correct :)
