American Society of Heating and Ventilating Engineers Guide, 1925-26 large ranges a properly designed hot-water plant and a properly designed steam system would be equally economical, but the first cost of hot water is very much above the first cost of steam.

American Society of Heating and Ventilating Engineers Guide, 1925-26 Practical rates of combustion run from 5 lb. per sq. ft. of grate in small heating boilers to 40 lb. per sq. ft. of grate in large power boilers depending upon the fuel and draft. 2.

American Society of Heating and Ventilating Engineers Guide, 1926-27 Long runs of pipe are used and expansion and contraction require more consideration than in house heating work; piping must be tied up, anchored, installations must be flexible; expansion joints are no more desirable in greenhouse heating than elsewhere; expansion must be com pensated for by "spring" of pipe and by swivel fitted joints, and expansion joints used where expansion may not be compensated otherwise.
