Greenhouse Heating. 



' ScBSCKiBERS are invited to write the 

 editor of the Heating Department, de- 

 scribing their troubles or askmg any 

 questions regarding the heating of green- 

 houses, thQ piping or boiler-room. But 

 please do not ask us to make a choice of 

 apparatus for you. Each article adver- 

 tised in this department of The Review 

 is good, and the advertisers sell them on 

 their merits. 



THE CHEAPEST FUEL? 



1 am building a greenhouse, 32x130 

 feet and about eleven feet high, for 

 growing lettuce, cucumbers and to- 

 matoes. I intend to heat the house with 

 hot water, but I cannot figure out which 

 would be the cheapest fuel. Here, in 

 southwestern Oregon, wood costs $8 per 

 cord; coal, $8 per ton; gas, $1.50 per 

 thousand cubic feet, or at the rate of 

 $1.25 per thousand for 15,000 feet and 

 $1 per thousand for 30,000 feet. I 

 shall greatly appreciate any informa- 

 tion you may give me on the sub- 

 ject. E.V.M. 



So much depends upon the character 

 of the coal and the heating qualities 

 of the wood that no really positive an- 

 swer can be given to this question. 

 Besides, the amount of wood in a cord 

 varies in different parts of the coun- 

 try; while it is a pile eight feet long 

 and four feet high, the length of the 

 wood may vary from sixteen inches to 

 four feet. However, even if it is 4- 

 foot wood, it is hardly probable that a 

 cord would have a heating value equal 

 to that from a ton of coal. 



If the coal is a good grade of run 

 of mine, one ton would probably equal 

 at least 10,000 cubic feet of gas, so 

 that at $8 per ton it would be cheaper 

 than gas at the minimum price of $1 

 per thousand feet. Even though the 

 saving of labor in the wav of firing 

 and removing the ashes when gas is 

 used is well worth considering, it is 

 not likely that under any circumstances 

 the gas would be found as economical 

 as the coal. 



A KANSAS CARNATION HOUSE. 



We are building a small greenhouse, 

 20x40, and should like to know whether 

 the piping we have planned is enough 

 to heat it for carnations, in this Kan- 

 sas climate. We are planning to use 

 two 2-inch flows along the roof, two 

 1%-inch returns on each side of the 

 solid bed, four li4-ineh returns under 

 each bench, and then a 2-inch return 

 back to the boiler, which is in the

basement of the house. The green- 

 house runs north and south and is about 

 four and one-half feet high to the 

 eaves, with eighteen inches of glass 

 in the east and west sides. The south 

 end contains a good deal of glass; 

 the north end is a solid stone wall, 

 with two small windows. We erpect 

 to bank up the north end with manure 

 above the windows in Winter. The side 

 walls and south end are stone also 

 up to the glass; that is, to the height 

 of about three feet. The height to the 

 ridge pole is nine and one-half feet. 

 We could put another l^-inch pipe all 

 around the solid bed if necessary. We 

 shall be grateful for suggestions con- 

 cerning the matter, as it is rather new 

 to us.- C. C.

of 50 degrees, it would be desirable to 

 have about seven square feet of ra- 

 diating surface for each foot in length 

 of the house. Two 2-inch flow pipes 

 would be sufficient to supply this 

 amount of radiation. In addition to the 

 radiation provided by the flow pipes, 

 5% feet will be required in the returns. 

 As 114-iiich pipe gives four and one- 

 third square feet of radiating surface
