its not desired, a muslin curtain, which 

 could be drawn up to the roof during 

 the day, would be helpful. 



To secure the temperatures men- 

 tioned, run a 2^-inch main under the 

 ridge and bring back four 2-inch re- 

 turns to the center of the house; there 

 increase the number to eight returns. 

 This number of returns would be 

 needed to secure the temperatures 

 named when the outside temperature is 

 as low as 20 degrees above zero. When 

 the outside temperature is 30 degrees 

 above . zero, it would be possible to 

 maintain the temperatures if two of the 

 returns at one end of the house and one 

 at the other end were left out, and 

 then, by firing a little harder when the 

 temperature drops to 20 degrees, there 

 would be little difficulty in keeping the 

 houses as warm as would be necessary. 



If possible, the top of the boiler 

 should be as low as, or lower than, the 

 level of the floor. By running the flow 

 pipe with a slight fall, the expansion 

 tank could be connected with the high- 

 est point in the system and no air 

 valves would be required. All of the 

 returns may be under the side benches 

 or they may be evenly distributed 

 under the four benches. 



RIGHT DISTBIBUTION OF PIPES. 



We are putting up a greenhouse, 18x 

 83, and should like to know what 

 amount of piping will be needed in it 

 and whether all the pipes can be placed 

 in the middle of the house, where they 

 would be most out of the way. We shall 

 use 1-inch pipe. The side walls of the 

 house are seven feet high and contain 

 six feet of glass above one foot of con- 

 crete. The height of the ridge is eleven 

 feet. Please state particularly whether 

 it would be advisable to attach all the 

 pipes to the middle posts. We want a 

 temperature of 45 to 50 degrees at 

 night. The lowest outside temperature 

 we have in this part of New York state 

 is about 15 degrees below zero. 



J. J. S. 



To heat a house 18x83 feet, with six 

 feet of glass in each of the walls, to 50 

 degrees with steam heat, one 2-inch 

 flow pipe, which could be fastened to 

 the posts two feet below the ridge, and 

 ten 1-inch returns will be needed. While 

 four of the returns may be placed upon 

 the middle posts, it will be advisable, 

 especially considering the amount of 

 glass in the walls, to have at least three 

 of the returns on each wall. Especially 

 if the end of the house is exposed, the 

 returns on the walls should start under 

 the end of the flow pipe, run each way 

 along the end of the house and then on 

 the side walls to the boiler end of the 

 house. 



HEAT FOR SWEET PEA HOUSE. 



We have in the course of construc- 

 tion a sweet pea house, 31x100, in which 

 we plan to plant five rows of peas at an 

 average of six feet apart. The peas 

 are to be planted in trenches dug in 

 the soil, twenty-four inches deep. This 

 depth of soil is to be increased by an 

 additional twelve inches contained in 

 12-inch side boards. We are at a loss 

 as to the best way in which to place our 

 heating pipes. We have a steam heat- 

 ing system. Is it more advisable to run 

 our pipes overhead or to run our coils 

 along the 12-inch side boards in the 

 walks! It is our plan to use some of 

 the space for growing violets and each 

 pea trench will have a 36-inch violet 



WHEN YOU BUY-arr A KROCSCHELL 

 'THE BOILER OF UNEQUALED FUEL ECONOMY' 



Ovi«i- 



The immense amount of direct self-cleaningf heatinsf 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 

 Kroeechell Boiler and mighty is their praise. The 

 year of 1913 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 customers' interest 

 first" — perfection of construction — factory to user prices 

 — honest and "true blue" boiler ratings — you simply 

 cannot lose.
