GALVANIZED PIPE. 



What are the advantages or disad- 

 vantages of using galvanized pipe in- 

 stead of black pipe for steam heating 

 in greenhouses? E. N, 



The chief objection to galvanized pipe 

 is its extra cost, and, in the second place, 

 it is not as good a radiator as black 

 pipe. It might last a little longer, but 

 the difference would not justify the ad- 

 ditional cost, were it as good as black 

 pipe as a radiator. L. C. C. 



TO PACX HOT VATER PIPES. 



What is the best method of packing 

 4-inch hot water pipes? Subscriber. 



The joints of 4-inch pipe can be 

 packed with oakum and red lead, or with 

 a cement made as follows : Sal ammoniac, 

 two ounces; sulphur, one ounce; clean 

 iron filings or borings, reduced to a 

 powder, twelve pounds, and water enough 

 to form a paste. L. C. C. 



HOT WATER FOR ONE HOUSE. 



I have an even-span greenhouse, 26x125 

 feet; height from top of bed to ridge, 

 ten feet; height from bottom of walk 

 to plate, four feet; height of beds, two 

 feet. The whole of the end walls and 

 the upper half of the side walls are 

 glass. The house runs east and west. 

 What size of boiler would I require, and 

 what size of maili pipe? How many 

 flows and returns would I require, and 

 where would you place them? I should 

 want to heat the house to 65 degrees 

 in zero weather in Massachusetts. 



The boiler-house will be at the north- 

 east corner, about thirty-six feet from 

 the entrance of the present greenhouse. 

 I shall have another house close to. the 

 boiler-house, so I shall want a large 

 enough main pipe to supply both houses. 

 I shall use hot water, with a boiler for 

 each house. Or would you advise me to 

 have one boiler for the two houses? 



G. B. W. 



The boiler to heat your house should 

 have a rated capacity for at least 1,500 

 square feet of radiation. I should pre- 

 fer one boiler large enough to heat both 

 houses, rather than one for each. You

can use pipe from li.^-inch up to 4-inch, 

 as you wish. I like 2-inch pipe for hot 

 water and have figured the requirements 

 of your house accordingly. A 3 V^ -inch 

 flow pipe and fifteen 2-inch returns will 

 do the work. If you wish to use two 

 flows instead of one, substitute two 2V^- 

 inch pipes for the 3 ^A -inch. L. C. C. 



FROM STEAM TO HOT VAT?R? 



We have three houses, which, ^o^ever, 

 are cut through crosswise by a shed, so 

 they may be treated as six houses. On 

 one side of the shed they are each sev- 

 enty feet long; on the other side of the 

 shed they are sixty feet, fifty-five feet 

 and thirty-five feet long, respectively. 

 We have been heating them with steam, 

 supplied by a twelve horse-power tubular 

 boiler, but as it is too small to do the 

 work, a change of some kind is neces- 

 sary. I have been thinking of putting 

 in hot water heat. Would you think it 

 advisable to do sot What size of hot 

 water boiler would I want? The houses 

 are eighteen feet wide ; ten feet to ridge. 

 The outside temperature at times goes 

 down to 20 degrees or 25 degrees below

zero here in Michigan. How many lines 

 of 2-ineh pipe would be required? How 

 many would you use for flows and how 

 many for returns? I should want to 

 heat the 35-foot house to 60 degrees; 

 the 55-foot house and the 60-foot house 

 should both be heated to 50 degrees. Of 

 the 70-foot houses, one will require a 

 temperature of 50 degrees, another of 

 60 degrees and another of 55 degrees. 

 We also have a shed running across the 

 ends of the houses, about forty feet long 

 and not over Ave feet high in the high- 

 est place. 



Do you think it would pay to make 

 the change, considering the difference-
