Greeohoose Heating. 



A HOUSE VITH A LEAN-TO. 



I should be pleased to get some advice 

 as to heating a greenhouse with hot 

 water. The length is 200 feet, running 

 east and west. The width is twenty- 

 seven feet, with a 5-foot lean-to along 

 the north side. The height to the gut- 

 ters is seven feet and the height to the 

 ridge is thirteen feet ten inches. Tlie 

 length of the sashbars on the south side 

 is fourteen feet and on the north side 

 sixteen feet. There are movable sashes, 

 about two feet and a half deep, in the 

 south wall. There is no partition be- 

 tween the lean-to and the main house. 



I wiali to run two mains across the 

 center of the house, large enough to sup- 

 ply another house like the foregoing lat- 

 er on, with the flow pipes overhead. I 

 should like to use 1 14 -inch pipe for the 

 returns. How many and what size of 

 flow pipes shall I use and how many re- 

 turns f The desired temperature is 55 

 degrees, with the outside temperature 

 sometimes 15 degrees below zero. I 

 should like to have as many of the re- 

 turns as possible along the walls, and 

 also a few under the bench in the lean- 

 to for bottom heat. How many feet be- 

 low the ground should the return open- 

 ing on the boiler be? C. B. 



In order to successfully heat the 200- 

 foot house with hot water it will be 

 necessary to locate the boiler at one side 

 an(J 100 feet from either end; this will 

 then give the maximum eflScient length

of piping for hot water. If I under- 

 stand the dimensions of the room to be 

 heated *it is 27+5=32 feet in width by 

 200 feet in length. If this is the case 

 there should be a 4-inch flow pipe lead- 

 ing from the boiler in either direction to 

 the far ends of the house, and there di- 

 viding to return by twenty-two l^^-inch 

 returns or eighteen 2-inch returns, ar- 

 ranged on the side walls and under the 

 benches. If the boiler can be located so 

 the top of the shell of the boiler is below 

 the level of the return pipes in the house, 

 the return opening on the boiler will be 

 low enough. L. C. C. 



HEAT FOR ADDITIONAL HOUSE. 



I am going to erect a new house, 40x 

 120 feet, sixteen feet to the ridge, six 

 feet to the gutters. There will be two 

 feet of foundation and four feet of 

 glass in the side walls. The house will 

 run east and west. The temperature 

 runs to 10 degrees below zero, and once 

 in a great while to 16 degrees below. 

 I have a tubular boiler, 36x72 inches, 

 containing thirty-six 4-inch tubes, and 

 carrying 1,300 feet of 4-inch cast-iron 

 pipe. I wish to maintain a temperature 

 of 60 degrees. How much additional 

 pipe will I require and will the boiler 

 carry it? In horse-power the boiler 



A SAVING IN 

 PIPE COST... 



If you are increasinK your steam 

 beatiDK system, why not install a sys- 

 tem that requires smaller mains than 

 others and save in cost of pipe, fit- 

 tioKS, valves, etc.? 



At the same time secure advan- 

 tages and economy not possessed by 

 other systems.

 several things.

will rate fourteen to fifteen; it has two 

 inlets and two outlets for hot water. 

 Can I run one or two flow lines over- 

 head and place the returns under the 

 benches or on the side walls? The 

 boiler will be located at one end of the 

 range and can be sunk as low as neces- 

 sary. Would two or three flows over- 

 head and five or six returns under the 

 benches or on the side walls be prac- 

 ticable and what would be the best way 

 to arrange them? B. P. G. 



It is possible to give you only a 

 partial answer from the data given. 

 The boiler has a capacity to carry about 

 1,950 square feet of radiation. Your 

 house requires about 1,800, so you have 

 only a small margin on the right side.
