Creenhonse Heating. 



RELATIVE HEIGHT OF PIPES. 



I should like to get a little advice on 

 heating. I have a hot water boiler, rated 

 at 1,300 square feet. At present it is 

 heating about 600 feet of 2-inch pipe. I 

 wish to know whether the boiler would 

 heat my new house satisfactorily if 

 the flow pipe is about two feet lower 

 than in the older house, where the pipes 

 are on the posts. In the new house I 

 wish to place all the pipes under the 

 benches. This would cause the pipes 

 to be about one foot lower than the low- 

 est return in the old house and about 

 two feet lower than the flow pipe. The 

 boiler shed is between the two houses, 

 which run east and west. As the flows 

 are all tapped, could I place tees on 

 them, so as to get more branches? 



A. L.— Mo. 



So many things have to be taken into 

 account when considering a question 

 like the foregoing that it is not pos- 

 sible to give a definite answer. About 

 the only fact relating to the heating 

 system that is stated is the capacity of 

 the boiler, which should readily handle 

 three times the present radiating sur- 

 face. While we are informed that the 

 flow pipe in one house is two feet lower 

 than in the other, and that there will 

 be a difference of one foot or more in 

 the height of the returns, nothing is 

 said regarding the height of the differ- 

 ent pipes above the boiler, upon which 

 the whole matter largely depends. 



In a general way, we will say that if 

 the lowest part of the returns in the 

 house to be heated is two feet above the 

 top of the boiler, there will be no diffi- 

 culty in securing a good circulation in 

 all of the pipes, although it may be nec- 

 essary to have a valve upon either the 

 main flow or the main return pipe in 

 the other house, in order to regulate the 

 circulation of the water and secure a 

 uniform temperature in the two houses. 

 This will be more difficult if the returns 

 in one house arc one foot below the top 

 of the boiler while they are one foot 

 above the Imiler in the other house, 

 since the better circulation will be in 

 the higher returns, especially when the 

 lower ones are below the top of the

boiler, but even then the circulation can 

 he regulated to a large extent by means 

 of valves on the higher pipes. 



If the flows are sufficiently large, 

 other pipes may be added if needed, but 

 we would not care to furnish more than 

 200 square feet of radiation with a 

 2 inch flow, 400 square feet with a 2^^- 

 inch flow or 750 square feet with a 

 3-inch flow pipe, unless more than four 

 feet above the boiler. 



A SASH HOUSE. 



Would it be presuming too much to 

 ask you to give me a detailed descrip- 

 tion and plan of a sash house in which 

 to put geraniums a little later? I wish 

 to build one about sixty feet long. What 

 would be the best width for 3x6 sashes? 

 What would be the proper height of the 

 walls, without glass in the sides? Could 

 the house ])e built and heated in such a 

 wav that there would be no need for

benches, so that I could. plant chrysan- 

 themums to follow geraniums? Could 

 the pipes be hung on the posts, with 

 the mums in the beds, and a path ex- 

 cavated to any depth needed? 



What would be the best way to pipe 

 this sash house and how much 2-inch 

 pipe would be needed for 50 degrees in 

 zero weather? I have some 1^-inch 

 pipe; could it be used with success in 

 a house of this size? I wish to do away 

 with the benches if I can; if not, I will 

 build them. The soil is a sandy loam, 

 through which the water drains away 

 readily. Any information will be 

 greatly appreciated.

For such a house as the one described, 

 we would set two rows of posts so that 

 they can be used to support the walls 

 of a house measuring ten and one-half 

 feet wide outside, and would construct 

 the walls of sheathing and siding, using
