Greenhouse Heating. 



Subscribers are invited to write the 

 editor of the Heating Department, de- 

 scribing their troubles or asking any 

 questions regarding the heating of green- 

 houses, the piping or boiler-room. But 

 please do not ask us to make a choice of 

 apparatus for you. Each boiler adver- 

 tised in The Review is a good boiler, and 

 the advertisers sell them on their merits. 



ONE HOUSE AND ADDITION. 



Would three coils of pipe — two coils 

 of four li^-inch and ohe coil of four 

 2-inch pipes — heat a . house 25x100, 

 twelve feet to the ridge and six feet to 

 the eaves, -with four feet of glass! We 

 are building a 16-foot addition to our 

 present house. Would 1-inch or 1%-inch 

 pipe be preferable? We expect to heat 

 with steam and wish to keep a night 

 temperature of 50 degrees in both 

 houses. Our location is southern Kan- 

 sas. C. W. E. 



There is no reason why the amount of 

 piping you suggest should not keep up 

 your temperature properly. I would 

 prefer the 1%-inch pipe to the smaller 

 size. I would suggest that, instead of 

 bunching your pipes in coils, you dis- 

 tribute them through the house more. 

 Two pipes on each side, with the others 

 about even distances apart, would give 

 you a more uniform heat through the 

 house than is possible with coils placed 

 so far apart. A. P. J. B. 



HEATED WITH FLUE AND COII*. 



I am seeking information on the 

 heating question. I have one house, 

 15 X 75, and am heating it with a 

 brick flue. Now, I wish to ascertain 

 whether I can put a coil in the fire- 

 box, install an expansion tank, pipe 

 the house from the coil and make it 

 work successfully. The temperature 

 in this part of Washington state 

 rarely, if ever, falls to zero. Please 

 tell me what size and what quantity 

 of pipe will be needed and what will 

 be the best way to arrange it. 



W. T. J. 



The question does not afford such 

 information as would make a definite 

 answer possible, but it is inferred 

 that for some reason the flue does not 

 heat the greenhouse satisfactorily. As 

 a rule, a combination of flue and hot 

 water heating is not recommended, but 

 in cases like this, where it is desired 

 to supplement a flue already con- 

 structed, hot water might be intro- 

 duced, provided the furnace is four 

 feet long and there is a good draft. 



For the heating coil in the furnace 

 use three runs of 2-inch pipe, running

a 2-inch flow up from the front end of 

 the coil and connecting with an expan- 

 sion pipe at the highest point. Then 

 run the flow downhill, about two feet 

 below the ridge, to the farther end, 

 and connect with two 2-inch returns 

 to be carried back to the heater, one 

 on each side of the house. 



PAINT FOE STEAM PIPES. 



We wish to repaint the iron gutters, 

 posts, hot water and steam pipes. Please 

 inform us whether the asphalt paints 

 commonly sold are suitable for this 

 purpose, or is the effect injurious to 

 •roses, carnations and other plants when 

 used on steam and hot water pipesf 



A. F. C. 



Great care should be taken in the se- 

 lection of paints for use on greenhouse 

 boilers and heating pipes, as if they 

 contain tar the house will be rendered 

 practically worthless for growing plants 

 untiL tl|e p^int has been burned off. A 

 heamig pipe with 'a lough surface viill 

 give off more heat than one with a 

 smooth, glossy surface; hence the heavy 

 asphaltum paints, though all right for 

 boilers, are not desirable for radiating 

 surfaces. If asphaltum is used, care 

 should be taken that it is of good qual- 

 ity, or serious harm may result.

For heating pipes a good paint can 

 be made by stirring up enough lamp- 

 black and turpentine to make a fairly 

 thick paint and then adding one-half as 

 much linseed oil. 



HEATING A PAETITIONED HOUSE 



I am building a greenhouse, 22x85 

 feet, running north and south. The 

 side walls will be four feet high, of 

 boards. The south end will be joined 

 to the boiler-shed. The north end will 

 be glass, except the lower four feet, 

 which will be solid, like the sides. 

 The house will be eleven feet high to 

 the ridge. Will two 2Vi-inch feed 

 pipes and four l^/^-inch returns be 

 about right for a temperature of 50 

 to 60 degrees? If not, please advise 

 me how to pipe it. I should like to 

 run a glass partition through the 

 house, twenty-two feet back from the 

 boiler-shed, to enclose a room for pot 

 plants. Can I do this and have that 

 end warmer than the other endt I 

 want to use the most of the house for 

 carnations. I shall use a hot water 

 system. I shall have solid beds for 

 the carnations and raised benches for 

 the pot plants. My location is south- 

 ern Indiana. F. H. H,
