Greenhouse Heating. 



Subscribers are invited to write the 

 Editor of this Department with regard 

 to any details of greenhouse heating that 

 are not understood. But please do not 

 ask The Keview to make a choice of 

 apparatus for you. The greenhouse 

 heating equipment advertised in this 

 paper is, we believe, the best for the 

 trade to buy, and each article the best 

 in the special field of its adaptation. 



WILL THE BOILER SUFFICE? 



I propose to build two connected 

 greenhouses, one of them 14%xl30 and 

 the other 14%xl20. The height to the 

 eaves and to the middle gutter will be 

 four feet; the height to the ridge in each 

 house will be eight feet. The side walls 

 and gable ends will be without glass and 

 will be constructed of two thicknesses 

 of 1-inch drop siding, with building 

 paper between. The houses will run 

 east and west. 



I can get a ten horse-power return 

 flue tubular boiler, seven feet long and 

 thirty-six inches in diameter, with 

 twelve 3-inch flues. The fire-box is 

 about 20x36 inches. Can I heat these 

 two houses with this boiler, using hot 

 water? I wish to maintain a night tem- 

 perature of 50 to 55 degrees, here in 

 the climate of central Ohio. Will it 

 be necessary to put the boiler in a pit? 

 What size and height of smokestack 

 should be used with this boiler? How 

 should the piping be arranged, using 

 2-inch returns? In the north house 

 there will be three raised benches; in 

 the south house, two raised benches and 

 one solid bed. C. A. B. 



To heat the houses described to 55 

 degrees in zero weather will require 

 about 1,200 square feet of radiation. 

 If the boiler described has an actual 

 rating of ten horse-power, it will an- 

 swer for the two houses, but I can- 

 not figure its capacity as much over 

 seven horse-power so far as heating 

 surface is concerned. There is a slight 

 excess of grate area, so I conclude that 

 it would be possible to maintain a tem- 

 perature of 55 degrees except in zero 

 weather, and by carefully tending the 

 fires it should be possible to keep the 

 temperature up to 50 degrees in any 

 weather that is probable in central 

 Ohio. 



It will be advisable to have a 10- 

 inch smokestack forty feet high or a 

 12-inch stack thirty feet high, and to 

 place the boiler in a pit. For radiation 

 use two 21^-inch flows on the plates in 

 each house, with three 2-inch returns 

 connected with each of the flows.

 SYSTEM 



EflScient and profitable handling 

 of condensation; returns condensa- 

 tion to boiler at initial temperature 

 —perfect circulation; proper drain- 

 age; removes large proportion of air 

 as well as condensation. Boiler is 

 situated on top of ground; conven- 

 ient; no "up and down stairs"; la- 

 bor-saving; economy in fuel. 



These are only .ome of the rea- 

 sons why a Morehead is needed in 

 your greenhouse. Have our engi- 

 neers give you complete informa- 

 tion. It's absolutely free.

THE FUEL MARKET. 



The market reporter for the Black 

 Diamond presents a decidedly gloomy 

 picture of the condition of this week's 

 coal business, stating that the market 

 is dull as a result of general business 

 depression, that "storage coal con- 

 tinues to satisfy all demands and the 

 market if without purchasing power. ' ' 

 The natural inference would be that 

 now is a good time to make arrange- 

 ments for the purchase of coal. 



The authority referred to goes on to 



WHtN YOU to Y- OCT A KROESCHEtL 

 THE BOILER OF OENUINB EFFICIENCY 



The customers' interest first — Is the 

 basis of the Kroescbell standard, and 

 this principle malces the Kroeschell 

 policy the most liberal of -all In the 

 greenhouse boiler business. 



The great variety of boilers that 

 we make places us In a commanding 

 position. We make every type of 

 boiler that Is used, from the smallest 

 house heater to the largest water tube 

 steam boiler (600 horsepower). For 

 the above reason we can furnish the 

 most efficient boiler unit In every case. 



It is the Kroeschell principle to sup- 

 ply only that type of boiler which is 

 best suited to the conditions, and un- 

 der no circumstances do we take any 

 other stand. 



Every Boiler of the Highest Standard 



MATERIAL — Governed by Kroeschell specifloa- 

 tions — the best that money and brains can pro- 

 duce. WORKMANSHIP— the kind that ii an 

 inspiration to all boiler makers, BOILER £F- 

 FICIENCY^-determined by actual tests under 

 working conditions. BOILER RATINOS— honest 

 and true blue — guaranteed actual working ca- 

 pacities. 



Probably you have wondered why the 

 Kroeschell Greenhouse Boiler Is not 

 sold by any of the greenhouse mate- 

 rial and construction companies. In 

 Justice to all concerned we feel it is 

 our duty to state that the Kroeschell 

 Boiler Is never sold by any one but — 

 The KROESCHELL BROS. QO.— We 

 have no agents, and as our prices are 

 based on sales direct from factory to 

 user, we do not quote anyone dealing 

 in boilers special resale prices. Our 

 stand in this matter has brought out 

 a lot of competition; uevertheless, the 

 great efficiency of the Kroeschell 

 Greenhouse Boiler cannot be disputed, 

 and In spite of the keen competition 

 the Kroeschell Greenhouse Boiler Is 

 heating more glass than any other 

 make.
