Greenhouse Heating 



■-■ ' ' ■ . .■■ -■ ■■ . ■ r 



SxTBSCRiBxas are invited to write the 

 editor of this department with regard to 

 anj details of greenhouse heating that 

 are not understood. W]}en 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 

 helpful, also, to have a sketch showing 

 the location of the houses. 



BURNING OIL. 



What do you know about the Worth- 

 ington burner? Is it efficient and 

 economical and what results have been 

 obtained with it! P. S. — Mo. 



So far no knowledge has been had 

 concerning the results secured with the 

 burner in question. However, the con- 

 dition under which the oil is burned 

 should give good results. There is no 

 question but what the use of oil will 

 result in a considerable saving in firing 

 and removing ashes and will do away 

 to a large extent with the smoke and 

 soot. Whether it will be economical 

 will depend upon the cost of the oil as 

 compared with that of coal. 



STEAM TUBUIiAB BOILEB. 



How many square feet of glass will 

 a Kewanee steam high-pressure tubular 

 boiler heat? The boiler in question is 

 3%xl5 feet and has thirty-two S^^-inch 

 flues. The temperature to be maintained 

 in zero weather is 55 degrees. 



J. B. F.— 111. 



Had the size of the grate been stated, 

 it would have been possible to make a 

 more definite estimate. However, if 

 the grate bars are four feet in length 

 the boiler will probably heat at least 

 14,000 square feet of glass to 55 de- 

 grees in zero weather. There should 

 be about 2,000 square feet of radiation 

 in addition to the connecting mains. 

 These calculations have been made on 

 the basis of a boiler rated at forty 

 horsepower and the estimate is a con- 

 servative one. 



BETUBNS TJNDEB BENCHES. 



What are the heating requirements 

 for two greenhouses, one of which is 

 10x30 feet, six feet high at the plate and 

 eight feet high at the ridge, having 

 ends one-half of glass; the other is 

 18x24 feet, with a lean-to 10x20 feet, 

 with one and one-half feet of glass on 

 the south side and the north side 

 boarded up to the plate? Hot water 

 is to be Uijcd and a temperature of 60 

 degrees in weather 10 degrees below 

 zero is desired. It is also desired that 

 the returns run under the benches. 



J. J. B.— N. Y. 



From the description it is understood 

 that the houses are so built that only the 

 north wall of (lie lOxSO-foot house and 

 the south wall of the lean-to are ex- 

 posed. Under these conditions it would 

 be advisable to use one 2^/^-inch flow 

 and seven 1%-inch returns in the nar- 

 row house and two 2V^-inch flows and 

 eleven 1^-inch returns in the 18x24 

 house. For the lean-to use one 2i^-inch

The Quickest Water Heater 

 in the World 



The Kroeschell Boiler heats quicker, gives 

 more heat and uses less fuel than any 

 other boiler. 



The efficiency and economy of Kroeschell 

 Boilers can in no way be better proved than 

 in the following statements of three big men 

 of the greenhouse trade: 



Charles Totty 



"The Kroeschell Boiler I installed last year usually 

 runs from 10 p. m. to 6 a. m. without attention. I 

 do not have the least trouble to keep temperatures 

 in the coldest weather. The boiler has given entire 

 satisfaction. The Kroeschell is the best boiler we 

 have ever handled." 



Frank Oechslin 



"I have used Kroeschell Boilers ever since 1 built 

 my first greenhouse. They have always given me 

 the very best satisfaction and I believe them as 

 good boilers as money can buy." 



Chas. McCauley* 



"In speaking of the Kroeschell Boiler as an econ- 

 omical greenhouse boiler I cannot say too much. 

 Personally I have had the pleasure or misfortune 

 to fire nearly every make of greenhouse boiler on 

 the market and I can safely say the Kroeschell is 

 the best of them all."
