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 Eeview to make a choice of ap- 

 paratus 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. 



HOUSES ON SLOPING GROUND. 



I am planning to build a greenhouse 

 this season, or perhaps two greenhouses, 

 each 20x50. One will be used for 

 flowers and the other for vegetables. 

 The houses will be even-span and will 

 run north and south. The side walls 

 will be at least six feet high. The boiler 

 room will be at the north end. The 

 south gables will be glass and there 

 will be twenty inches of glass in the 

 side walls. The ground slopes to the 

 east and the first house erected will be 

 at the base of the incline. If I raise 

 the second house eighteen or twenty 

 inches, can I heat both houses satisfac- 

 ^torily? Please give directions for the 

 piping of both houses, though I may 

 not be able to build both of them this 

 season. L. E. B. — Mich. 



The letter does not state what classes 

 of vegetables or plants will be grown in 

 the houses, but if a temperature of 60 

 degrees is needed in one house and 50 

 degrees in the other we would suggest 

 the following arrangement of the pip- 

 ing: 111 either case we would use three 

 2iX.'-inoh flow pipes, placing one upon 

 each ])latc and the other three feet 

 under the ridge, with twelve 2-inch re- 

 turn pipes for 60 degrees and eight 2- 

 inch returns for 50 degrees. If it is 

 found more convenient to put in 2-inch 

 pipes for tlie flows and li/Si-inch pipes 

 for the returns, use three flows, with 

 fifteen returns for 60 degrees and ten 

 returns for 50 degrees. 



While all of the flow. pipes may start 

 at or near the boiler, 4-inch main flow 

 and return pipes may be used for each 

 of the houses. In all cases the return 

 coils should be connected with the boiler 

 by means of pipes of the same size or 

 capacity as that of the main flow pipes. 

 Unless the difference in the level of the 

 houses is more than two feet, tliere 

 should be no difficulty in securing an 

 even distribution of the water, although 

 it will be advisable to place valves, at 

 least uj)on the flow pipe or pipes leading 

 to the higher house, with wliich to 

 clieek the flow to that house in case

The immense amount of direct self-cleaning: heating: surface and 

 the thin vertical waterways cause this type of boiler construction 

 to heat water quicker than any other form of boiler. 



Hundreds of Florists' Review readers are using the 

 Kroeschell Boiler and mighty is their praise. This 

 year has brought us an enormous number of new 

 customers who have seen our boiler in operation 

 at other places. We attribute the large sales of 

 this season to the good work the Kroeschell Boiler 

 is doing everywhere. With our policy — "the cus- 

 tomers' interest first" — perfection of construc- 

 tion — factory, to user prices— honest and "true 

 blue" boiler ratings — you simply cannot lose.
