ireenhoBse Heating. 



The Review is glad to answer, in this 

 department, any inquiry connected with 

 greenhouse heating. If you are in doubt 

 about any matter of heating, set down 

 all the details and the Review will try 

 to help you out. Full names are re- 

 quired, but not for publication. 



RANGE OF FOUR HOUSES. 



I intend to erect four houses in the 

 spring. Will you kindly post me on the 

 following questions: 



I. Size of houses is 22x50, connected, 

 for growing carnations, mums, vege- 

 tables, bulbs, etc. Which aspect would 

 give me most sun and light in winter 

 months, location in Ontario? 



II. The temperature here has been 

 known to reach 35 degrees below zero. 

 I wish to use wood by day and coal by 

 night; no night fireman. What make 

 and size of boiler would be most suited 

 to my purpose? 



III. What size of hot water pipes 

 do you recommend? What number of 

 flows and returns, and position of same? 

 What depth of boiler pit should be pro- 

 vided? W. P. 



I. I prefer house with the ridge run- 

 ning north and south witlk a head house 

 over the north end. Such houses get 

 more sun during the period when sun is 

 lowest and reflect most when sun is most 

 nearly vertical. 



II. I do not think you can use the 

 system you contemplate of alternate 

 flring with wood and coal without a 

 night fireman, and then with doubtful 

 results. You will require a boiler with 

 very capacious fire box, one long enough 

 to take 4-foot or even 8-foot wood. 



III. I would suggest locating the 

 heating plant in the middle of the head 

 house so as to carry a 4-inch header or 

 riser in each direction from the boiler 

 to the center line of the two middle 

 houses and continue to the center of the 

 side houses by 3-inch pipe. Carry a 

 3-inch riser under the ridge of each 

 house to the far end and return by fif- 

 teen 2-inch returns in each of the out- 

 side houses and fourteen 2-inch returns 

 in each of the middle houses. The boiler 

 plant should have a capacity for at least 

 2,500 square feet of radiation. I would 

 further suggest that the boiler be pro- 

 vided with two 4-inch openings and each 

 line of 4-inch pipe be taken off inde- 

 pendently. 



Put the expansion tank up high, twelve 

 or fifteen feet above highest point in 

 the piping system, and connect it 

 directlv to the main return close to 

 the boiler. L. C. C.

HOUSE IN OHIO. 



I have a greenhouse 20x70, with four 

 rows of 2-inch pipe down each side and 

 two rows of 4-inch pipe down the center. 

 I heat with hot water. The boiler has 

 six sections, with an expansion tank of 

 thirty gallons. This system will not heat 

 my house. Where is my trouble, and 

 how can I fix it to heat to 70 degrees in 

 zero weather? 



How far should a bench be from the 

 side of the greenhouse, and how far from 

 the pipes? Will the bench affect the 

 heating of the house if it is over the 

 pij)es? D. B. 



In the first place, the use of two large 

 flow pipes so retards the flow of hot

water in the system that the heat is 

 largely given off before it reaches the 

 true radiating pipes. The only function 

 of flow pipes is to convey the hot water 

 to the returns to do its work. The two 

 4-inch pipes should be replaced by one 

 3-inch pipe. The radiation in the house 

 is not suflScient for the temperature de-
