Greenhouse 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 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. 



WHAT PIPES TO USE. 



Wo slioiild like information relative 

 to heating a gropuhousc 2.3x100 feet. 

 We have ii (i-soction United States 

 Radiator boiler .No. 227. with two SVo- 

 ineh feeds and two IJi/^-incl\ returns, in 

 a pit five feet deep. Wo liave 400 feet of 

 4-inch pipe on hand, wliicli we should 

 like to use if 2;)ossible. It is necessary 

 to keep the house at 55 degrees when the 

 outdoor tenipernture is 10 degrees below 

 zero. 



Tlie side w.ills are four and one-half 

 feet high, of which thirty-two inches is 

 gla.ss on the south side. The north 

 side is boarded up and the gables arc 

 glass with the exception of two feet. 

 There is a lean-to on the south side ten 

 feet wide,! which is separate from the 

 other house. I do not want heat for it 

 now. 



The 4-iiu-h i)ipe we ha\e on li;nid is 

 calk pipe from sixteen to eigliteen 

 feet long. What is the best method of 

 calking jiijies.' F. 11. & H. 



We suggest using a 3M>-inch flow pipe 

 on the plate of the south wall, connect- 

 ing it with one of the flow ports of the 

 boiler. With this flow pipe supply a 

 coil of three 4-inch returns under the 

 side bencli along the south wall. Run 

 the returns at as high a level as possi- 

 ble, unless they nrc above the top of the 

 boiler. 



For the remainder of tlic flow pipes 

 run a 3-ineh main about three feet below 

 the ridge and another on the north wall. 

 Join these to a 3^,/>-inch ]iipe and con- 

 nect it with the other flow port. 



For the other coils use thr( 



-inch 



returns in The middle of the house and 

 a 4-incli ;uid two 2-incli returns along 

 the nortli wall. 



For ealking the joints of tiie 4-inch 

 pipes we suggest using alternate layers 

 of o.'ikiiiH ."ind iron putty.

Christinas Business. 



Tlie outstanding feature of Christmas 

 business was the ease with which it was 

 handled. Business was far better than 

 anyone liiid expected. While ])rej)ara- 

 tions were being made for good busi- 

 ness, ther<' was a feeling of uncertniiity 

 that tlie florists would not admit. They 

 realize<l that they had to face difTercnt 

 conditions than ];ist year, when a high 

 record liad been established. However, 

 all came up to last year's mark and the 

 majority soared high above. Never be- 

 fore were so many early orders ]daced 

 by the regular flower buyers. Retailers 

 consc(|uently put in their orders early, 

 and the wholesalers knew in advance 

 liow t'l hnndle stock. Shipping business

TO THE MAN WHO NEEDS A BOILER 



"The customer's interest firsf'-is the basis of the KROESCHELL standard. This 

 principle makes the KROESCHELL Policy the most liberal of all in the Green- 

 house Boiler business. The great variety of boilers that vre make places us in a 

 commandinK position. It is the KROESCHELL principle to supply only the type 

 of boiler best suited for the conditions. For this reason we always furnish the 

 most efficient boiler unit in every case.

OUR EXPENSE 



The KROESCHELL has proven its worth in (nany of the large establishments in 

 this country. It has freauently been selected by the most careful buyers in 

 competition with all other types of boilers. Its efficiency and capacity are com- 

 pletely beyond any other boiler. 



KROESCHELL BOILERS have no bulky, soot accumu- 

 lating surfaces— you avoid the disagreeable work and 

 trouble indispensable to cleaning boilers with compli- 

 cated and tortuous back and forth passages. 



The superiority of our boilers has resulted in the removal and abolishment of 

 hundreds of cast iron sectional boilers— in every instance KROESCHELL BOILERS 

 give more heat with the same piping with less fuel.
