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 Beview to make a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment advertised in this paper is, we 

 believe, the best tor the trade to buy, and 

 each article the best in the special field 

 of its adaptation. 



HARD COAL BESTBICTIONS OFF. 



On account of an increased supply 

 and accumulation, all restrictions as to 

 shipment of anthracite coal of egg and 

 pea sizes have been removed, it is an- 

 nounced by the Fuel Administration. 

 Notices to this effect have been mailed 

 by the administration to all anthracite 

 shippers and distributors. 



All shipments of egg and pea coal to 

 territories formerly embargoed or states 

 formerly zoned out to anthracite coal 

 are now without restrictions, and it will 

 be permissible to ship egg and pea coal 

 to such markets as may be found for it. 

 This permission applies only to egg and 

 pea coal and the restrictions on other 

 Bizes continue. 



As the result of the action here re- 

 lated, the situation is that egg and pea 

 coal, steam coal, buckwheat. No. 1 and 

 smaller sizes, can be shipped to any 

 point where they may be marketed. The 

 restrictions on anthracite shipments now 

 apply only to the sizes stove and 

 chestnut. 



TOO HOT AND DRY. 



I am writing for advice in regard to 

 a greenhouse of which I have charge. 

 The house is situated on the top of a 

 4-story factory building and is 18x50, 

 with a partition across the center. One 

 room is used for vegetables and the 

 other for flowers. The heat is furnished 

 by a low-pressure boiler. The main feed 

 pipe travels one block before arriving at 

 the greenhouse. This pipe is 2V^-inch, 

 but is reduced to 1%-inch inside the 

 greenhouse. There it feeds the coils, of 

 which there are two in each section, 

 each coil containing eight 1%-inch 

 pipes. The coils are located under the 

 side benches. 



I have had a hard time trying to keep 

 the heat down. The temperature runs 

 up to 80 degrees, with the heat turned 

 off on one side. What would you advise 

 me to do? The air in the house is ex- 

 tremely dry; there seems to be abso- 

 lutely no moisture. On top of the pipes 

 I have placed eight pans, which hold 

 over a pail of water, and when I enter 

 the house in the morning these pans are 

 dry. J. S.-— 111. 



The letter does not state the amount 

 of glass, if any, in the side walls of 

 the greenhouse, nor the temperature that 

 must be maintained in the greenhouse 

 in the coldest weather. If we consider 

 a house without glass in the walls and 

 where a night temperature of 60 de- 

 grees is desired, we would use only eight 

 1%-inch pipes for each section of the 

 house. This would be just one-half the 

 present number, as we understand it. 

 Four pipes could be placed in a coil on 

 each wall, or under the side benches, 

 and to keep down the heat in mild 

 weather we would use shut-off valves at

Neither in the East or West, nor the North or South has any other 

 make of boiler ever equaled the performance of the Kroeschell— 

 installed for 3,974,605 square feet of class in 1916-1917. Every 

 customer immensely satisfied. The hiKh efficiency and low cost of 

 operation makes the Kroeschell the best of all boilers for Florists' use. 



KROESCHELL BOILERS have satis- 

 factorily and permanently solved the 

 effective burning of screenings. They 

 will burn the worst grades of coal, even 

 the dirtiest culm or sawdust and wood 

 refuse. 



Greenhouse owners like the KROES- 

 CHELL because of its extreme simplic- 

 ity and freedom from trouble. Asa fuel 

 saver, it pays its own way. The KROES- 

 CHELL will increase your heating plant 

 efficiency 20 to 40%. 



The KROESCHELL has proven its worth in many of the large establish- 

 ments in this country. It has frequently been selected by the most care- 

 ful buyers in competition with all other types of boilers. Its efficiency 

 and capacity are completely beyond any other boiler.
