Greenhouse Heating. 



SxTBSCRiBERS 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 Beview to make a ehoice 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. 



CAPACITY OF SMALL HEATEK. 



I have a hot water heater which I 

 used to heat a brooder house, but since 

 I changed the system of brooding I no 

 longer need the heater for that pur- 

 pose. The temperature in this local- 

 ity has been known to drop as low as 

 20 degrees below zero, though below- 

 zero temperatures are rare. I should 

 like to use this heater in a small 

 greenhouse, for forcing bulbs, growing 

 geraniums and other hardy plants, and 

 starting stock for outdoor planting. 



The heater is a round affair, with a 

 water jacket around the fire, and the 

 coal is put in at the top. An auto- 

 matic regulator is attached. The grate 

 area is 185 square inches. The makers 

 claim that, at a conservative estimate, 

 the- heater will control 1,000 feet of 

 radiation, with hard coal. I have in 

 use 600 feet of 1%-inch pipe. What 

 size of greenhouse would this heater 

 care fort It must be set in a pit at 

 least thirty inches below the lowest 

 pipe of the coils. I enclose a picture 

 of the heater, so you can see what it 

 is like. W. W. B.— Pa. 



Although the heater is of an efficient 

 typs, judging from the accompanying 

 picture, I would not care to use it 

 for more than 250 square feet of radiat- 

 ing surface, which is about the amount 

 that vrill be furnished by 600 linear 

 feft of 114 -inch pipe. This will heat 

 1,000 square feet of -glass to 50 de- 

 grees in zero weather, and this may . 

 be what is claimed by the manufactur- 

 ers, instead of radiation. For a small 

 house a width of twenty feet will be I

The mains are arranged to take care of a future addition of 40,000 so. ft. of glass; 

 2-inch returns Are used throughout the entire range and each 2-inch retuVn line is <^6n- 

 trolled by 1-inch gate valve (strictly a Kroeschell feature), insuring perfect control. It 

 is a gravity job; the circulation is perfect, reaching the extreme ends of range in fifteen 

 minutes. The Kroeschell Generator (the high speed gear for hot water heating) is also 

 used for this system. 



"Your No. 15 Kroeschell Boiler heats our entire range. We maintain a 

 temperature of 60 degrees in our greenhouses, and this temperature is easily 

 maintained even in the very coldest weather. Your boiler has given entire 

 satisfaction. It is the best and quickest heater I have ever used or seen. 

 I have found the boiler very economical in the use of fuel and labor, as 

 it is uot necessary to use the best coal, and any labor will do for a fire- 

 man. The Kroeschell Piping System with Generator works like a charm. 

 When I want to sulphur. I can heat the water up to 230 to 210 degrees and 

 I get the same results as from steam. Seeing is believing— all growers are 

 invited to call. Any further information concerning boiler and piping sys- 

 tem will be gladly given. We had a large number of florists at our place 

 recently, and they all thought we bad the finest equipped plant in the busi- 

 ness." THE RIVERBANK COMPANIES,
