Greenhouse Heating. 



Subscribers are 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 fhe best in the special 

 field of its adaptation. 



HAS INSTALLED ly^-ltJCK PIPES. 



I have just installed a hot water heat- 

 ing system in my greenhouse, which is 

 22x32, six feet high to the gutters and 

 fourteen feet to the ridge. The sides 

 and one end are double boarded. There 

 are three feet of glass in each side wall 

 and in one gable end. The boiler room 

 is at the east end of the house, with a 

 cellar for the boiler. The house is well 

 built, but is exposed to the northwest 

 winds. I have used a 3%-inch pipe to 

 lead from the boiler into the house. 

 The 3%-inch main then branches out 

 into four 2-inch flows, one for each 

 bench. Each flow is connected with four 

 1%-inch returns. I wish to heat the 

 house to a temperature of 60 degrees 

 when the outside temperature is 15 de- 

 grees below zero. The boiler is four 

 and one-half feet below the return pipes. 



F. O. W.— la. 



So far as can be determined from the 

 description given, there is no reason why 

 the system will not give a good circula- 

 tion, although the radiation is not sirf- 

 ficient to give a night temperature of 60 

 degrees when the temperature is 15 de- 

 erees below zero outside, except with 

 hard firing or with a system under pres- 

 Bure. As a rule, we prefer to use re- 

 turns larger than 1^-inch for hot water, 

 but in a short house, and with the top 

 of the boiler four feet below the re- 

 turns, they should give satisfactory re- 

 sults, especially when there are only 

 four for each 2-inch flow pipe. 



As nearly as we can determine, there

are at least 1,200 square feet of glass 

 in the house, for which at least 400 

 square feet of radiation should be used 

 and 450 square feet would be better, 

 while there are less than 300 square 

 feet in the system. At least twenty-two 

 1^4-inch returns should be used. We 

 would place a 2%-inch flow pipe upon 

 each plate and one under each purlin, or 

 about halfway from the gutters to the 

 ridge. With each flow pipe we would 

 prefer to use four 2-inch returns, al- 

 though 1%-inch or even l^/i-inch pipes 

 might be used, with eighteen of the 

 former and twenty to twenty-two of 

 the latter in the house. 



Since the piping has already been in- 

 stalled, we would suggest the addition
