The above data re for estimating purposes. They assume a hypothetical
location at Norfolk, VA for each of the four facilities used as typical in this
manual. 20% glass area is assumed.
* The apparent inconsistency in the relative capacities of hot water
storage derives from efficiencies in heating units; low requirements may best
be met with small heating units and larger tanks.
