Greenhouse Heating. 



SuBSCBiBERS are invited to write the 

 Editor of this Department with regard to 

 any details of greenhouse beating that 

 are not understood. But please do not 

 ask The Beview 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. 



RETURN WATER UNUSUALLY HOT. 



I am about to build a violet house, 

 16x100, with no glass in the sides. It 

 will be a duplicate of another grower's 

 house in this vicinity, which is heated 

 by a Wilks hot water boiler, 36x48, 

 in a pit two and one-half feet below 

 the surface, with two 3-inch flows and 

 four 3-inch returns. While this gives 

 excellent results, the owner claims that 

 the water returns to his boiler rather 

 hot, and we are both curious to know 

 whether it would be better to use three 

 3-inch returne on each side instead of 

 two. I have the 3-inch pipe on hand. 

 I shall be much obliged for any in- 

 formation that you can give. 



A. E. B. 



From the facts presented, it would 

 appear that the principal reason for the 

 water in the returns being unusually 

 hot is the large size of the boiler. To 

 heat a house 16x100, in your Massa- 

 chusetts climate, to a temperature suit- 

 able for violets, not more than 500 

 square feet of rttdiation will be needed 

 and twenty-five per cent of this can

generally be cut out, except in zero 

 weather. To supply this amount of 

 radiation, the boiler need not be more 

 than twenty to twenty-four inches 

 square, according to its construction. 

 Two 3-inch flow pipes and four 3-inch 

 returns would be ample, and valves 

 should be placed upon two of the re- 

 turns so that they can be cut out in 

 mild weather. A better way of pip- 

 ing the house would be to use two 2%- 

 inch flows and six 2-inch returns. 



PIPINa SWEET PEA HOUSES. 



I have just built three houses, each 

 141/^x75 and six and one-half feet high 

 to the gutters. I heat with hot water. 

 I intend to run two 2-inch flows and 

 four 1%-inch returns in each house. 

 Would this be sufficient to maintain a 

 temperature for sweet peas in this part 

 of Colorado, where the outside tempera- 

 ture sometimes drops as low as 20 de- 

 grees below zero? Would it be better

to place the returns near the ground or

 so I cannot lay the returns under them, 

 but I intend to hang them on the gut-

By firing heavily when the outside 

 temperature is below zero, it will be 

 possible to grow sweet peas success- 

 fully by using two 2-inch flow pipes 

 and six 1%-inch returns, provided a 

 closed system is used. There are sev- 

 eral so-called generators or circulators 

 on the market, by means of which the 

 water is run under pressure, and, by 

 being able to raise the temperature of
