PIPING IN MICHIGAN. 



I want to go into the violet business 

 and would like some information on the 

 subject. I have a house 20x55, with 

 side walls three and one-half feet high 

 and the peak six and one-half feet above 

 the side walls. The house runs north 

 and south, with a glass front on the 

 south end. How many runs of pipe and 

 of what size will be required to heat 

 this house, and how should I arrange 

 them? I am figuring on hot water heat- 

 ing. Could I use a steam boiler and 

 what size will I need? ALso what size 

 regular water heater? A. F. F. 



Your violet house can be piped in the 

 following way with satisfaction, I be- 

 lieve: Use a 2-inch flow under the ridge, 

 carry hot water to the far end and re- 

 turn by ten 1%-inch returns, arranged 

 on side walls one above tne other and 

 given a good slope from one end of the 

 house to the other. The elevated expan- 

 sion tank, connected with main returns 

 to the boiler, should not be omitted. A 

 good hot water boiler will, I believe, 

 give you less trouble than to attempt to 

 convert a steam boiler. L. C. C. 



HEAT FOR A VIOLET HOUSE. 



I have a greenhouse to be used for 

 violets. It is 17x41 and runs east and 

 west. It measures three feet to the 

 eaves and eight feet to the ridge. It 

 has alternate ventilators in the ridge. 

 The west gable is glass, with a glass 

 door, and there are two feet of glass 

 in the sq^th side, but none in the north 

 side. The east end is attached to a 

 boiler room, having a cellar 12x20 and 

 six feet deep, in which the boiler will be 

 placed for hot water heating. Will a 

 Hitchings boiler. No. 22, be large enough 

 to heat the house in the climate of west- 

 ern New York? How many feet of 1%- 

 inch pipe will be needed, or would you 

 recommend some other size? Any help 

 you can give me about installing the 

 heating plant will be most gratefully re- 

 ceived, E. H. 



A boiler rated to carry 250 feet of 

 radiation should have ample capacity 

 for the house in question. If piped with 

 l^^-inch pipe, which is a good size for

short runs of hot water, the house will 

 require a 2-inch flow under the ridge 

 and nine returns of l^A-inch pipe, five 

 on the most exposed side and four on 

 the other, all arranged in manifolds and 

 placed well up on the side walls of the 

 house. L. C. C. 



TWO SMALL HOUSES. 



As you oflFer your army of readers of 

 the Review information for the asking 

 regarding their heating apparatus, I ven- 

 ture to ask for help from you. I have a 

 greenhouse 13x30, with 576 feet of glass 

 exposed, and at right angles to this 

 house I have a shop 12x40, with an office 

 12x14 attached. I am heating these 

 with a hot water boiler, which is rated 

 at 500 feet of radiation, with a fire pot 

 eighteen inches in diameter, a 3-inch 

 outlet at the top and a 7-inch smoke flue, 

 with two 21/^-inch returns. 



Now, what I want to know is, if I 

 make over the shop into a greenhouse 



18x40 feet, with 700 feet of glass ex- 

 posed, would my boiler be large enough 

 to heat both houses for carnations in this 

 part of New York state, where the 

 thermometer sometimes goes down to 30 

 degrees below zero? The total glass ex- 

 posure in the two houses would be about 

 1,300 square feet. The present green- 

 house, 13x30, is even-span, nine feet to 

 the ridge and five feet to the eaves, 

 with eighteen inches of glass on the east 

 side. The house 18x40 will be three- 

 quarter span, nine feet high to the ridge, 

 five feet high on one side and six feet 

 high on the other. 



I have now ten returns of li/j-inch 

 pipe, with one overhead flow of 21^- 

 inch pipe, in the greenhouse, and seven 

 returns with a 1%-inch flow in the shop 

 and oflSee. Do you think ten runs would 

 be enough of IV^-inch pipe in the 18x 

 40» house, if you consider the boiler 

 large enough ? G. E. M. 



I do not know that I fully understand
