Creenhonse Heating. 



SuBSOBiBKBS 8X6 invited to write the 

 Editor of this Department with regard to 

 any details of greenhouse heating that 

 are not understood. But please do not 

 ask The Review to make a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment advertised in this paper is, we 

 believe, the best for the trade to buy, 

 and each article the best in the special 

 field of its adaptation. 



HEAT FOR BOOTINO CONIFERS. 



We intend to install a heating system 

 in a shed attached to our packing house. 

 The shed is eighty feet long and will be 

 heated by a 7-8ection Moninger boiler, 

 located directly to the south. We wish 

 to know what piping will be needed 

 to heat this shed to the right temper- 

 ature for rooting cuttings of conifers, 

 etc. The temperature, I suppose, should 

 be 55 to 60 degrees in the coldest 

 weather. The height of the shed is eight 

 feet at the west side and twelve feet at 

 the east side, where there is a wooden 

 wall. The west or outside wall contains 

 three feet of concrete; the remainder 

 is glass. The south end also is glass. 

 There are three benches, arranged as 

 follows: A 3-foot bench against the 

 concrete wall on the west, a 6-foot bench 

 in the center and a 3-foot bench at the 

 back or east side. V. N. — N. C. 



The letter does not state the width 

 of the house, but from the width and 

 number of the benches we infer that it 

 ia approximately sixteen feet. We are 

 also in some doubt about the construc- 

 tion of the house. It would appear that 

 there is a wooden wall twelve feet high 

 on the east side and that the west wall 

 has three feet of concrete and five feet 

 of glass. The building is spoken of 

 as a "shed," but we infer that the 

 roof as well as the south gable is of 

 glass. 



If this is correct, there would be not 

 far from twenty-two feet of glass, meas- 

 uring from the top of the concrete wall 

 to the plate on the east side. For a 

 temperature of 50 to 60 degrees in zero 

 weather we would use a 2i/^-inch flow 

 pipe upon each plate and nine 2-inch 

 returns, distributed under the benches. 



PIPING A SET OF FRAMES. 



\ am enclosing a sketch of a pro- 

 posed set of ten coldframes, each ]2x 

 100, to be used in the spring, from 

 March onward, to take care of bedding 

 stock, geraniums, etc. They will be 

 about twelve feet away from the green- 

 house boiler room. How can I heat the 

 frames successfully with 2-inch pipe 

 for flows and l^/Vinch pipe for re- 

 turns? I shall use glass cloth if 

 practicable, sloping it to each side like 

 a roof, with a ridge along the middle 

 of each frame. The boiler pit is sunk 

 six feet below the surface of the ground. 

 How many of these frames can be heated 

 by a boiler rated at 750 feet of radia-

tion, when the outside temperature is 

 about 10 degrees above zero? The 

 frames will require a temperature of not 

 less than 45 degrees at night. 



Could I run the main flow and return 

 directly across the end of the row of 

 frames and just below the surface of 

 the ground, so as to allow teams to be 

 driven over? And can I attach a tee 

 for each frame, thence running the pipe 

 down one side of the frame and back 

 on the other side, dropping it down into 

 the return? How much more heat can 

 I retain by using glass over the glass 

 cloth? I intend to use the Skinner sys- 

 tem of irrigation in connection with 

 this arrangement. Can you give me any 

 suggestions on the proper installation 

 of the sprinkling system?

For a hotbed twelve feet in width 

 we would use, for a temperature of 45 

 degrees when the outside temperature 

 is 10 degrees above zero, one 2-ineh 

 overhead flow pipe, placed about one 

 foot below the ridge, and a 2-inch 

 return pipe upon each side wall. A 

 little later in the season, or if the plants 

 are such that it may be ])ossible to drop 

 the temperature to 40 degrees in cold 

 nights in March, one 2-inch flow

answer. They would also sufiice if 

 glass sashes are placed over the glass 

 cloth covering. Provided the top of 

 the boiler is two feet below the level of 

 the returns, there should be no diflB- 

 culty about running the main flow and 

 return pipes as proposed, but we prefer 

 to run an overhead flow, with two re- 

 turns on the sides of the frames for the 

 heating pipes. 



In severe weather, each of the frames 

 will require nearly 200 square feet of 

 radiating surface, so that a heater rated 

 for 750 square feet will only handle 

 four of the frames. Later on, it should 

 be able to heat from six to ten of the 

 frai7ies, according to the outside tem- 

 jioraturo and the amount of heat desired 

 inside the frames. 



There should l)e no difliculty in wa- 

 tering the frames with the Skinner sys-
