Greenhouse Heating. 



^^^^ ^ ■■— - ■ I » 



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 Review 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. 



THE COAL MABKET. 



The coal market is dull, unquestion- 

 ably dull, principally for the reason 

 that the majority of retailers and many 

 consumers purchased heavily during 

 the period of uncertainty preceding the 

 new agreement between the operators 

 and miners in the bituminous districts, 

 and therefore are now well supplied 

 with fuel. The general resolution seems 

 to be to reduce the stocks on hand be- 

 fore beginning to worry about a future 

 scarcity. One cause of uneasiness is 

 the likelihood of a shortage of labor at 

 the mines when business- again becomes 

 active, but this is too vague a forebod- 

 ing to cast much of a gloom over the 

 situation. In the smokeless market, it 

 is said, "there is every evidence of a 

 congestion of unsold coal. Thus the 

 market technically is soft, but prices 

 are firm." Contracting on the new 

 basis is active and seems to indicate, 

 in Chicago at least, an acceptance of 

 the new circular, which quotes mine- 

 run at $1.35 f. 0. b. the mines and $3.40 

 f. 0. b. Chicago. 



WHICH IS THE CHEAPER FUEL? 



I have two greenhouses. One of them 

 is 18x45, with no glass in the side walls. 

 The other is 29x76, with two feet of 

 glass in the sides. They are to be 

 heated with hot water. Which would 

 be the cheaper fuel for these houses, 

 gas at 25 cents per thousand or slack 

 coal at $1.25 per ton? If I install a 

 large boiler, will it be necessary to fire 

 more than once during the night in 

 cold weather? How would I then keep 

 the house cool when the sun comes out 

 early and there is still a fire in the 

 boiler? S. L. W.— 0. 



The first cost of natural gas will be 

 more than that of slack coal at the 

 prices mentioned, but if allowance is 

 made for the labor of firing, handling 

 ashes, etc., the gas will be less expen- 

 sive than the coal.

We have assisted many- growers In the development of successful heating systems 

 and our engineering department offers a service, and the benefit of a knowledge and 

 experience of incalculable value, to those who contemplate the erection of heating 

 plants, no matter how small or how large, hot water or steam. 



KROESCHELL CENTRAL HEATING SYSTEM- 



Installed for John G. Frisz, Vincennes, Indiana. 



This plant at present covers over two and one -half acres of ground- space 

 and was formerly heated by a large number of boilers located in different parts 

 throughout the plant. 



Two years ago Mr. Prisz contemplated an addition of a new block of houses, 

 and as the heating systems in use were not successful, Mr. Frisz called on us 

 for advice. 



We suggested a central heating system and recommended that all boilers 

 be torn out and disposed of, and in place of same advised that the new power 

 plant be located at the extreme north-east corner of the plant alongside of the 

 railroad tracks. 



The new equipment consists of two No. 18 Kroeschell hot water boilers 

 (central station type), one 60 H. P. steam boiler, two 8-inch circulating steam 

 boilers, and steam condenser. Only one of the hot water boilers was required 

 to heat the entire plant, although the temperature had reached 20° below zero, 

 the coldest winter in this section for many years. 



In planning this heating system the equipment installed allows for a great 

 increase in glass. 



With our system there is no expense on the operation of the circulating 

 pumps, as the exhaust steam from same is utilized to reheat the water coming 

 from the greenhouses. With this system there is absolutely no waste. 



The same season the new heating system was installed 20,000 sq. ft. of glass 

 was added to the plant, and in spite of this the new system made a saving of 

 over 12 carloads of coal over the amount of fuel consumed the season before; 

 and remember, the new plant heated 20,000 additional glass besides.
