American Society of Heating and Ventilating Engineers Guide, 1932 Of course, where the required heating surface is estimated by empirical or rule-of-thumb methods, refinements in approximating fuel consump tion are not warranted, but rule-of-thumb methods often lead to unsatis factory results and should be avoided in heating work where more accurate methods are available.

American Society of Heating and Ventilating Engineers Guide, .1932 The steam requirements for water heating should be taken into account, but in most types of buildings this load will be relatively small compared with the heating load and will seldom occur at the time of the heating peak.
