Better Than Steam 



Pontiao, 111., March 16, 1910. 

 Gentlemen:— We have no trouble whatever in keeping a temperature of 50® to 56" in our carna- 

 tion houses, and 60® in our loee houses, in the coldest weather. We fire once in three hours on very 

 • cold nighta, and other times once during the night. The boiler has given excellent satisfactioa ; it is 

 simply wonderful. We had a fire box boiler previous to this, but your improved system has it beat to 

 death in every way. Your system of piping, together with your improved Generator system, has steam 

 skinned to death in bo many ways. We were on the market to buy high pressure steam, but after re- 

 ceiving such reports of your improved hot water system, we concluded that your experience was worth 

 something, and have been delighted at the results, and so glad we took your advice and put in hot 

 water instead of tteam. Very respectfully, W. J. Miller & Son.

with a lean-to 10x20 feet, built across 

 the south end. In the larger house 

 there are three coils, each of which 

 contains five 1%-inch pipes. For these 

 there is one 2-inch flow pipe, which con- 

 nects with the coils at the south end of 

 the house. A 2-inch return pipe leads 

 to the boiler. In the lean-to there is 

 one coil of five 1%-inch pipes. This is 

 connected with the boiler by a 2-inch 

 flow pipe, and the 2-inch return pipe is 

 connected with the return from the 

 other house about ten feet away from 

 the boiler. 



It is probable that a part of the dif- 

 ficulty, at least, is due to the fact that 

 an endeavor is made to return all of 

 the water from twenty li/^-inch pipes 

 through a single 2-inch return, and the 

 distribution of heat to both houses will 

 be improved if the return from the 

 lean-to is connected independently to 

 the boiler. It would also be better if 

 the expansion pipe Were connected to 

 the highest point in the system. 



The sketch does not show the length 

 of the coil in the lean-to, but it ap- 

 pears to be about twelve feet, so that 

 there would not be more than thirty- 

 five square feet of radiation in the 

 house, whereas, to give a temperature 

 of 50 degrees, there should be at least 

 sixty feet, allowing qne linear foot of 

 1%-inch pipe for every two square feet 

 of glass. The house L^xSO contains
