Greenhouse Beating. 



BOILER CAPACITY. 



I have a common round boiler, 3x7 

 feet, with thirty 3-inch flues. The boiler 

 is now used for hot water and is set in 

 brick, all except a steam dome which 

 projects from the top. It is claimed to 

 be a twenty horse -power boiler. How 

 many square feet of glass will the boiler 

 carry to maintain a temperature of 55 

 degrees when it is 10 dejjrees below 

 zero outdoors! I use 1 Ms -inch and 2- 

 inch pipe. At present I am heating only 

 one house, 21x60, but I intend to heat 

 three more short-span houses, each lOx 

 70,' connected to the first house on the 

 north; walls to be six feet high and no 

 partitions between any of the houses. 

 Will this be the limit of my boiler ca- 

 pacity, or can I heat a 7-room dwelling 

 in addition? The dwelling stands about 

 sixty-five feet from the boiler. 



^ - . E. A. M. 



The houses in question, to maintain 

 a temperature of 55 degrees, will re- 

 quire a little less than 1,200 square feet 

 of radiation, and, although your boiler 

 is not more than fifteen horse-power, it 

 should have a capacity of about 1,900 

 square feet of radiation, which is about 

 700 square feet more than demanded by 

 the greenhouses. If the pipes to and 

 from the dwelling are carefully protect- 

 ed I think the boiler will carry both the 

 dwelling and greenhouses, but it will be 

 working under a full load in cold 

 weather. L. C. C. 



HEATING TWO HOUSES. 



I have built a new greenhouse at the 

 east end of my old one. It is 21x50 

 and twelve feet to the ridge, with three 

 feet of glass in the side walls. The old 

 house is 26x77 and eight feet to the 

 ridge. The boiler-room, 14x20, is in the 

 southeast comer of the old house. Will 

 my No. 1 Kroeschell hot water boiler 

 be large enough to heat the plant? How 

 many flows and returns and what size 

 will I need to heat to 60 degrees in 

 Wisconsin climate? I would also like to 

 know hQW much concrete to put around 

 the posts' of the new house to keep it 

 from spreading, posts to be three feet in 

 the ground. J. B. 



The boiler you have should be ample 

 to heat the plant in question. The new 

 house can be heated by using 2-inch pipe 

 arranged in coils, five pipes in each coil,

fifteen in all, the length of the house. 

 One pipe in each coil should be a riser, 

 carried if possible direct from the boiler 

 to the coil. If this cannot be arranged, 

 then a 3-inch pipe should be carried 

 from the boiler to the end of the new 

 house and there divide to feed the three 

 2-inch flows for the three coils. 



The character of the soil will have 

 more to do with the amount of concrete 

 to use about the posts than any other 

 single factor. If the soil is dry and 

 resistant, holes eighteen inches across 

 should be large enough; but if the soil 

 is soft and yielding at any season it is 

 doubtful if you can insure the house in 

 this way. At any rate I should support 

 the structure so as to take as much 

 thrust off the side wall as possible. This 

 can be done by posts under the ridge 

 and braces on the purlins, or by truss 

 rods between the purlihs. L. C. C. 



TO HEAT FOUR GREENHOUSE. 



I am about to build two even-span 

 north and south houses, connected, each 

 24x50, also two even-span east and west 

 houses, connected, each 26x200 or 26x 

 250, with extension in view. The last 

 two are to be used for cut flowers.

pipe, 1,300 feet of 3-inch, 1,000 feet of 

 2J/4-inch, 2|pO feet of 6-inch and 1,000 

 feet of 1-inch. I also have a quantity of 

 steam radiators for my dwelling. I want 

 to use steam. I don't want to use over- 

 head mains. Should I use hot water 

 and steam and what size of boiler? I 

 can go as deep as I like with my boiler- 

 pit. Where should I locate the boiler? * 

 The temperature outdoors, here in Mani- 

 toba, sometimes reaches 50 degrees be- 

 low zero. When the sun goes down, in 

 the winter, it gets cold very quickly; 

 that is why I would prefer steam. '

The 6-inch pipe will be too large for 

 the steam plant so far discussed, but as 

 soon as you get 30,000 square feet of 

 glass the 6-inch pipe will come in play. 

 By using the l^j-inch, 214-inch and 3- 

 inch pipe you can arrange a combination 

 Pteam and hot water plant which will 

 work with satisfaction. If you decide 

 to use this system, I should advise locat- 

 ing the boiler-pit so as to divide the 

 houses so that no run will be more than 

 100 feet from the boiler, if possible. If 

 steam alone is used this will not be of
