fifty feet of the service building. Please 

 state what you consider the proper sizes 

 of pipe to use and the number of flows 

 and returns necessary to heat these 

 houses to 55 degrees. The capacity 

 of the boiler is ample, and it has a 

 4-inch flow and a 4-inch return opening. 

 We are located in New York state. 



Also kindly pass your opinion on 

 the following: Our supply tank for 

 watering our plants is located directly 

 over the boiler room, on the second 

 floor of the service building. These 

 additional houses necessitate a larger 

 expansion tank. Could we run our ex- 

 pansion pipe fr^n the boiler to this 

 tank? This tank holds about ten bar- 

 rels of water. Would such a body of 

 water be detrimental to the working 

 of the liot water svsteni? E. B. 



The houses can be heated by using 

 either three 2-inch flow pipes or two 

 214-inch flow pipes. Two flows can be 

 carried on the plates, and if 2-inch 

 pipe is used, one can be a foot or two 

 under the ridge. In the 20-foot house 

 nine or ten 2-inch return pipes will be 

 required, while twelve or thirteen will 

 be needed in the 2()-foot house. It 

 makes no difference how large an ex- 

 pansion tank is used, but considerable 

 elevation is helpful, if the piping is 

 not i)roperly adjusted or is below the 

 top of the heater. 



OAS OE COAL AS FUEL? 



Will you kindly tell me whether sat- 

 isfactory results can be obtained by 

 the use of natural gas M'ith Kroeschell 

 hot water boilers? Which would be less 

 expensive, gas at the rate of 50 cents 

 per thousand cubic feet or coal at $2.95. 

 per ton? A. .T. P. 



Coal at $.'! ]»er ton will be the chefiper 

 fuel to use. At the figures stated by 

 A. J. P., the cost of coal as fuel would 

 be only one-third the cost of gas at the 

 rate quoted. This estimate is based 

 on natural gas having an efficiency of 

 1,000,000 B. T. U. per thousand cubic 

 feet, compared with a low grade of 

 coal having 10,000 B. T. U. per one 

 pound. Kroeschell Bros. Co. 



Bed Oak, la. — Charles A. Berg is 

 building additional houses for bedding 

 plants, etc., for the wholesale trade. 



More Heating 



and less water space than 

 is contained in any other 

 boiler. (Note the many 

 flues set close together.) 

 This is one reason why 

 the users of the 



''Superior Standard" Greenhouse Boflers 



find them perfectly satisfactory. We frequently receive re-orders 

 from florists who have tested these boilers thoroughly and found 

 them even " Superior" to our claims.
