Greenhouse Heating. 



MORE FIPINQ NEEDED. 



How many runs of 1%-inch steam 

 pipe would it take to heat a house 

 13x125 and twelve feet to the ridge, 

 to 56 degrees, when the outside tem- 

 perature is 20 degrees below zero? 

 How many runs of l^/i-inch pipe will 

 it take to heat a house 21x150 and 

 fourteen feet to the ridge, to 60 degrees, 

 with the same temperature outside? 

 Will a 4-inch steam main take care o# 

 40,000 square feet of modern glass, or 

 will it take care of more? I enclose a 

 drawing which shows the piping as 

 we intend to put it in. Will you be 

 kind enough to make suggestions as to 

 any changes that you think should be 

 made? I am located in southeastern 

 Wisconsin. H. C. 



The sketch shows the ground plan 

 of a house twenty-one feet wide, to 

 be heated to 60 degrees with l^/i-inch 

 pipes, of which one is located under 

 each of the gutters and two under each 

 of the three benches. As near as can 

 be determined from the plan, the ar- 

 rangement of the pipes would be sat- 

 isfactory, but, under the severe condi- 

 tions mentioned, there should be a con- 

 siderable increase in the amount of 

 radiation, and four more lines, making 

 twelve in all, will be required if the 

 house is to be heated without crowd- 

 ing the boiler. In case there is any 

 glass in the walls, one additional pipe 

 will be required for each two feet in 

 height of the glass. The drawing ap- 

 pears to show the coils fed from a 

 4-inch main, which is carried across the 

 middle of the house, with 2-inch con- 

 necting pipes leading to the coils on 

 either side. This would be all right 

 if the coils were not more than 100 

 feet long, but for a house 21x150 feet 

 the connecting pipes should be 2%- 

 inch. 



For the house 13 x 125 feet use six 

 lil>-inch pipes, with one additional 

 pipe /or each two and one-half feet 

 of glass in the walls. 



While the foregoing plan will give 

 good results, many would prefer to use 

 one 2-inch overhead flow and five V/y- 

 inch returns in the narrow house, and 

 one 2V^-inch flow and ten 1 14-inch re- 

 turns for the wide house. If the steam 

 is carried in the mains at forty pounds 

 of pressure, a 4-inch pipe will heat 

 40,000 square feet of glass to 56 de- 

 grees, but a 5-inch main will be needed 

 with low pressure and a 6-inch will be 

 desirable if very long. 



AN L-SHAPED ADDITION. 



At present we have a range of four 

 houses, running east and west. Begin- 

 ning at the south side of the range, the 

 houses are of the following dimensions: 

 25 X 116, 16 X 116, 20 x 100 and 22 x 100. 

 The boiler house is at the west end of 

 the 20-foot house. We now propose to

 tem and Kroeschell Generator. Greenhouses each 28 feet by 200 feet. 

 Garland Construction. 



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

 2 inch returns are used throughout ttie entire range and each 2-inch return line is con- 

 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 (tlie high speed gear for hot water boating) 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. 

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

 it is not 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 240 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 had the finest equipped plant in the busi- 

 ness." THE RIVERBANK COMPANIES,
