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
