It is estimated by a number of creameries which, have recently 
installed a water heating and storage tank similar to those shown in 
figures 7 and 8 that a saving in fuel of from 15 to 25 per cent has 
been effected , and it is believed that in most cases an even greater 
saving in fuel can be made if sufficient care and attention are given
