The Florists' Review 



June 29. 1922 



Greenhonse Heating 



Subscribers are invited to write the 

 editor of this department with regard to 

 any details of greenhouse heating that are 

 not understood. When information is de- 

 sired regarding the capacity of boilers, or 

 the amount of radiation required for a 

 greenhouse, the needed temperatures 

 should be stated in the inquiry, as well 

 as the amount of glass in the side walls, 

 and the dimensions and general arrange- 

 ment of the greenhouses. It is often help- 

 ful, also, to have a sketch showing the 

 location of the houses. 



DISCARD HOT WATER HEATER. 



The (liineiisions of my two green- 

 houses are 14x112 feet and 16x112 feet. 

 There are twenty-four inches of glass in 

 the south wall. The north wall is 

 boarded up. The boiler room is at the 

 west end of the liouses and their east 

 ends arc glazed. The temperature de- 

 sired is 45 to 50 degrees. How many 2- 

 inch lines will be required to heat this 

 house? I have a Furman water boiler, 

 but think it is too small for the pur- 

 pose. It has a fire box 12x30 inches, and 

 there are eight sections. LettufC will 

 be grown and hard coal will be burned 

 as fuel. J. J. L.— Ind. 



To heat a house 14x112 feet to 50 

 degrees in zero weather, it would be 

 advisable to use two 2%-inch flow pipes 

 on the side wall plates, connected at 

 the farther end of the house with four 

 2-inch returns in two coils located either 

 on the side walls or under the side 

 benches. For the house 16x112 feet use 

 an additional return. 



From the description given it is im- 

 possible to determine whether each 

 house is built by itself, or if they arc 

 constructed side by side with one wall 

 in common. However, a 2-incli return 

 should be added where there are two 

 feet of glass in the side wall of the 

 house. 



A hot water boiler of the stated size 

 would not be large enough for even one 

 of the houses. For the two houses use a 

 boiler about 24x30 inches, for hard coal, 

 or 30x30 inches for soft coal, for the 

 greatest economy of labor and fuel. 



REARRANGING SYSTEM. 



I have mailed you a sketch of a 

 greenhouse, 35x120 feet, and eighteen 

 feet to the ridge. There are four feet 

 of glass in the south wall and five feet 

 in the north wall, built upon two feet 

 of concrete. Kindly note the proposed 

 change, as indicated on the plan, and 

 give us vour opinion of the arrangement 

 as it stands. F. G. P.— Wash. 



The plan referred to above appears to 

 be of a house 35x120 feet, with the 

 ridge eighteen feet in height. There are 

 four feet of glass in the south wall 

 and five in the north, built upon two 

 feet of concrete. There are four lines 

 of 1-inch pipe on the purlins, of which 

 the two outer lines are supported by 

 1-inch pipe posts and the others by pipe 

 trusses. The principal changes advised 

 would be, so far as the construction of 

 the house is concerned, to substitutel%- 

 inch purlin posts for the 1-inch posts 

 indicated in the sketch. The present 

 heating is done by means of four coila 

 of 2-inch pipes and four 2-incli returns 



We are pleased to announce the 

 incorporation of the 



Brunswick-Kroeschell 



Company 



A consolidation of Brunswick Refriger- 

 ating Company of New Brunswick, New 

 Jersey; Kroeschell Bros. Co. and Kroe- 

 schell Bros. Ice Machine Company of 

 Chicago, Illinois. 



The new compzuiy w^ill maintain the 

 present offices and factories in New 

 Brunswick and Chicago with the various 

 branch offices, and will combine the 

 facilities and personnel of the former 

 companies so that it may cissure to its 

 customers the most efficient service.
