If I remember correctly a ton of airconditioning ( one ton of
ice melting in 24 hours)
is 12,000 btu's per hour.



Yes, Dan, but you missed a nit.

Water absorbs 80 calories per gram going from 0C ice to 0C water, but
then it also absorbs 1 calorie per gram to increase in temperature one
degree C.

So a gram of water would absorb 80+(say)20 calories going from 0C ice to
20C water.

If you were a creature that was comfortable at 110C, you'd gain an extra
boon, because water absorbs another 540 calories changing from 100C water
to 100C steam.

He hasn't "missed a bit". The "ton" rating is a well accepted industry
standard in the US.
