The Florists' Iteview 



August 13, 1914. 



that a curtailment of production due to 

 the departure of workers and an in- 

 creased sale abroad would limit the 

 supply of coal available to the west. 

 Some foresighted retailers have bought 

 a little additional coal. The situation 

 has been enough to confirm the new 

 circular price of $1.40." 



QUANTITY OF FUEL. 



I have four houses, each 20x150, with 

 3-foot sides and glass gables. The 

 houses are well built and tight. With 

 a good hot water system, what should 

 be the temperature of the water at 

 the boiler to keep the houses at a tem- 

 perature of 48 degrees, with the ther- 

 mometer registering 20 degrees outside 

 and no wind? Under such weather 

 conditions, about how many pounds of 

 coal should be required to keep the 

 water at the desired temperature dur- 

 ing the night, using good coal? About 

 how many pounds of coal and what 

 temperature of water would be neces- 

 sary to secure the same results on a 

 night when the outside temperature is 

 10 degrees above zero? I am located 

 in Delaware. C. O. 



It is not possible to give a definite 

 answer to the questions asked, as it 

 would depend upon various conditions, 

 such as the size of the boiler, the num- 

 ber and size of the flow and return 

 pipes and the character of the firing. 

 Thus, with a large boiler with a few 

 medium sized pipes, and an elevated 

 expansion tank or a closed system, the 

 water might be kept above 212 degrees 

 by heavy firing, while with a small 

 boiler and a large area of large pipes, 

 the temperature might be 100 degrees 

 or less, especially if the fires were not 

 pushed. 



If the radiation and boiler are prop- 

 erly adjusted to the size of the houses, 

 the boiler should have a rating of about 

 5,000 square feet, and each house 

 should be heated by three 2%-inch flow 

 pipes and six 2-inch returns, except the 

 one with glass in the side wall, which 

 should have an additional return. 

 Piped in this way, there should be no 

 difficulty in keeping the water in the 

 flow pipes above 180 degrees and in 

 the returns above 140 degrees, with an 

 open tank system. 



To maintain a temperature of 48 de- 

 grees, with the thermometer registering 

 20 degrees above zero outside, would 

 require from 500 to 800 pounds of coal, 

 according to its quality, and with an 

 outside temperature of 10 degrees 

 about twenty per cent more would be 

 needed. F. R. 



HEAT FROM EXHAUST STEAM. 



I should like to get some information 

 in regard to heating greenhouses with 

 exhaust steam. A new power plant 

 has been built at a distance of two 

 blocks from my greenhouses. Would 

 heating in this way be satisfactory, and 

 what would be the cost of piping the 

 steam from the power plant to the 

 houses? I mean the cost per lineal 

 foot. The houses are now piped for 

 hot water. They are located in Illi- 

 nois. The range consists of two houses 

 25x60, a lean-to 10x44, an office and a 

 boiler shed. I should like to have the 

 piping large enough to care for double 

 the present area of glass. Please state 

 the size of the pipe and the depth at 

 which it should be laid. G. F. P. 



Do you want true heating values for your money? Many 



florists, to their sorrow, have made the mistake of buying 



cast Iron boilers, which, because of their ratings, appeared 



to be cheaper than the Kroeschell boiler. 



The extravagant rating:s of cast iron boilers are misleadins:, and 

 liave been the cause of much disappointment and serious trouble to 

 many s^rowers. The fuel waste is enormous when cast iron boilers 

 are used for commercial purposes, such as greenhouse heating.

I bought a No 2 boiler in 1902. 

 Takes care of 70 )0 sq ft. of glass — 

 would take care of 2000 more. I 

 have bad a cast iron boiler, but it 

 broke down twice in four years, 

 always in the coldest weather. It 

 broke down Dec. 29. 1901, and I 

 lost all m.v stock in consequence. 

 I have now two No. 2 and one No. 

 (> Kroeschell boilers, and do not 

 worry about their breakine down.

We have a No. 4 Kroeschell 

 Boiler. It takes care of 7000 sq. 

 ft. of glass: it would take care of 

 twice that amount. 



I first had a new cast iron 

 boiler which lasted two yeirs, 

 when it cracked to pieces. The 

 second was a second-band boiler. 



I consider your boiler the best 

 paying investment I ever made. 



You can refer anyone to us.

Cast Iron Boiiors Crack 



I want to thank you for your promptness in shipping the boiler I ordered of 

 you on January 13. 1 had a breakdown, one of a battery of two cast iron 

 boilers cracked so it was impossible to use same, so I got you on the telephone 

 at 8::^ a. m., January 13. and ordered one of your hot water boilers. Same was 

 nut in my boiler room in the a/tomoon of January 15. after which we built 

 foundation and connected up. Since that lime the boiler has taken care of 

 same glass as the two cast iron boilers and does it easier and better in every 

 way. Signed. ANDREW BATHER, Clinton, Iowa. 



Do not make a mistake when selecting your new boiler; get a Kroeschell and you 



will never be disappointed.
