Greenhouse Heating 



Sttbscsibbbs are invited to write the 

 editor of this department with regard to 

 any details of greenhouse heating that 

 are not understood. When information 

 is desired regarding the capacity of boil- 

 ers, 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. 



CONVENIENCE VS. COMPASS. 



We are going to build six houses, 

 30x100, even span, with 8-foot gutters 

 and one-quarter pitch. The location we 

 wish to use is on a street that runs al- 

 most due southeast and northwest. We 

 wish to build square with the street. 

 Our land lies so that we can put the 

 houses either with the sides toward the 

 street or the ends toward the street. 

 We prefer the ends toward the street. 

 We expect to grow a general line of 

 plants, carnations and a few vegetables. 

 Which way would you advise setting the 

 houses, considering the high altitude and 

 the northern location? We have a great 

 deal of sunshine. Will vegetables do as 

 well with 8-foot gutters as with lower 

 onesf S. F. C— Wyo. 



It will really make little difference 

 whether the houses are built with the 

 sides or ends to the street. On some 

 accounts, for the plants to be grown in 

 the house, we should prefer to have them 

 with the ends to the street. However, 

 the matter of convenience would have 

 more weight than the points of the com- 

 pass. If the gutters are placed six feet 

 from the ground, the cost of construc- 

 tion will be reduced. For carnations 

 and vegetable crops, we should prefer to 

 have six feet rather than eight feet. If 

 any of the houses are to be used for to- 

 matoes or cucumbers, 8-foot gutters 

 would be desirable, although the middle 

 beds in 6-foot houses would answer well 

 for those crops. 



AEEANGING THE PIPES. 



I propose putting up a greenhouse, 

 21x57 feet. The front end will be of 

 glass, but the rear end will abut against 

 .1 garage. It is to be an even-span 

 house. Please state the best general 

 arrangement and the size of feed pipes 

 required if 2-inch returns are used. Al- 

 so, tell me the number of 2-inch returns 

 necessary. The two side benches are to 

 be three feet wide and the center bench 

 will be solid and ten feet wide. 



Also, please state the size of hot 

 water boiler that will be necessary. This 

 boiler will be located in the adjoining 

 residence, which is due north of the 

 greenhouse. Also, please tell me the 

 height and the size of the flue that will 

 be required. E. G. B. — Pa. 



As nearly as we can make out, the 

 side walls are to have three feet of 

 glass over three feet of tile. A temper- 

 ature of 60 degrees in zero weather is 

 desired. 



About 625 feet of radiation will be 

 required and we should select a boiler 

 rated for about 800 square feet of radia- 

 tion. This will mean, or it does in most 

 cases, a hot water heater with a grate 

 about twentv-four inches in diameter. 



Eliminate the Fuel Wasting 



Factors 



Th'? most destructive forces working 

 against the Nation's fuel resources are 

 soct and boiler scale. 



In these times every source of fuel 

 waste must be abolished from your 

 plants. The slacker, either man or me- 

 chanical equipment, has no place. 



Kroeschell Tubeless Boilers 



A boiler with bulky soot accumulat- 

 ing surfac s causes enormous fuel lo^r'ses. 

 F.iulty coal wasting boilers that cannot 

 be kept clean and which constantly keep 

 you in troublecanno longer be tolerated. 



NOT 



Meet the high cost and limited'sup- 

 ply of fuel with Kroeschell Boilers. 



These highly effective fuel- saving boilers 

 will make every dollar you spend. for fuel 

 do its utmost. 



CAST 

 IRON 



"''Further, improved* economy can Ibe 

 obtained if you centralize your heat 

 supply. Use only one boiler instead of 

 Ihre ' or four. It will save the exper.se 

 of needless fuel and labor. 



Successful greenhouse owners de- 

 mand Kroeschell Boilers to handle the 

 heat supply in a modem way— the larger 

 the p anl the more insistent is the use 

 of Kroeschell Boilers, as they carry 

 enormous glass areas with a minimum 

 of fuel and labor. 



Our Water Tube Steam Boiler 



Don't wait until the winter's distressing coal shortage 

 confronts you to begin iavestigating the advantages of 

 Kroeschell Boilers as a means of relieving the situation. 



ACT PROMPTLY! There is a Kroeschell for every 

 greonhouse plant, be it large or small.
