The Review is glad to answer in this 

 department any inquiry with regard to 

 greenhouse heating. Give all the details 

 of your problem, not only as a guide to 

 an intelligent answer, but so that others 

 similarly situated may derive a benefit. 



RANGE ON A HILLSIDE. 



I wish to inquire about the piping of 

 a new house, which I will designate as 

 house No. 1. It is 18x100, with side walls 

 four and a half feet high. It is built 

 on a hillside, sloping two feet from the 

 upper side of the house to the lower 

 side". The boiler will be more than fifty 

 feet farther down the hiUside, as I am 

 planning to build three more houses, 

 Nos. 2, 3 and 4, between house No. 1 

 and the boiler. Thus the bottom of the 

 boiler will be at least sixteen feet below 

 the level of the highest point of the flow 

 pipe in house No. 1, which is the only 

 house concerned in this inquiry. 



I wish to use no pipe above 2-inch 

 size for the flows. The expansion tank 

 will be about two feet above the highest 

 point of the flow, and I can place the 

 tank still higher if necessary. What 

 size of pipe will be best for the re- 

 turns, and how many will be required 

 to heat the house for common, mixed 

 bedding stock! I should prefer to use 

 11^ -inch or 1%-inch pipe. Where would 

 it be best to connect to the expansion 

 tank — at the highest point of the re- 

 turn, or should I run a pipe back to a 

 point near the boiler? I have plenty 

 of boiler capacity. 



Which is better — to slope the house 

 away from the workroom, so as to allow

the water to flow in the gutter to the 

 back end, or to slope it toward the 

 workroom and lead the water away in 

 pipes? How much fall is necessary? 



The space to be covered by the pro- 

 posed houses, Nos. 2, 3 and 4, is now 

 occupied by two detached greenhouses, 

 which will later be removed, and con- 

 nected houses will be built, with sepa- 

 rate flows running from the boiler to 

 each house. The workroom extends the 

 whole length and at house No. 1 will be 

 two stories high, for the expansion tank. 

 If I attach the expansion pipe close to 

 the boiler, I must have a pipe about 

 fifty-five feet longer than would other- 

 wise be required, but I would do this 

 in case the system would be better.
