Ireeflhonse Heating. 



TWO PARALLEL HOUSES. 



Kindly tell me how much hot water 

 pipe would be required to heat to 60 de- 

 grees two greenhouses, both in one block, 

 each house 16x65 and nine feet six inches 

 to the ridge. The walls are four feet 

 six inches, with two feet of glass, and 

 the south gable is glass. The houses have 

 even-span roofs and run north and south, 

 with a shed, 10x32, at the north end. I 

 should like to use 2-inch flow pipe and 

 1^-inch or IV^-inch returns. Would a 

 boiler rated at 350 square feet of radia- 

 tion be large enough? The temperature 

 never goes below zero in this part of 

 Oregon. C. K. 



Each of the houses 16x65 feet should 

 be provided with at least one 2-inch main 

 flow pipe and nine 1%-inch returns. If 

 the houses are built with a common par- 

 tition wall, five of the nine 1%-inch radi- 

 ating pipes can be placed on the outside 

 wall and four on the inside, in each 

 house. The two houses together require 

 a little over 600 square feet of radiation. 

 It will, therefore, be economical to in- 

 stall a boiler rated to carry not less than 

 750 square feet of radiation, and one 

 rated at 1,000 square feet will be still 

 safer. L. C. C. 



POOR CIRCULATION. 



Will you kindly inform me as to 

 where the trouble Ues in my heating sys- 

 tem? I have two connected, even-span 

 greenhouses, 20x50 feet. They run north 

 and south and the boiler is at the north 

 end of the west house. From the boiler 

 I have run one 3-inch pipe in both 

 houses, to the extreme south end of the 

 houses, returning by 2-inch pipes. There 

 are seven 2-inch pipes on the west side 

 of the houses, seven 2-inch pipes on the 

 east side and seven 2-inch pipes in the 

 center, where the two houses are joined, 

 there being no partition between them. 

 The expansion tank is located about six

feet directly over the boiler, which is a 

 4-piece hot water boiler, with a 28-inch 

 grate. 



Now, what I should like to know is, 

 what is the reason that I cannot get hot 

 water in all of those 2-inch pipes? The 

 best I can do is to get hot water in four 

 of them. The other three have cold 

 water, but still the return pipe, which is 

 located at the extreme north end of the 

 house, has hot water, and also the water 

 in the expansion tank is hot. The ex- 

 pansion tank has a circulation through 

 both the main and return. J. H. S.
