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. 



WHAT'S THE USE. 



The manufacturer of an oil burner 

 used by many western florists says: 

 ♦♦Since the Standard Oil Co. has been 

 brought to time (Oh! Oh!) the good 

 people are having a harvest in oils, 

 there only being a raise of 6V> cents 

 a gallon on gasoline and 3 cents to 

 6 cents on fuel oil. One more haul to 

 the carpet and users of gasoline will 

 have to resort to grain alcohoL Only 

 a few can get fuel oil at any price, and 

 the oil companies refuse to make any 

 contracts, even at market price at time 

 of delivery, to guarantee delivery. Now 

 what is the use of an oil burner?" 



UNDEEGEOUND STEAM CONDUIT. 



My present place consists of about 

 18,000 feet of glass, and I am planning 

 a new place across the road, the boiler- 

 room floor of which will be about 

 twenty-five feet lower than the present 

 place and 380 feet distant from it. 

 Will it be practicable to heat the pres- 

 ent place from the new? If so, what 

 kind of conduit would you suggest, 

 and what size of flow and return? The 

 present place will be devoted to carna- 

 tions and peas, the new place to roses. 

 I am located in northern Maryland. 



J. P. K. 



There will be no trouble in heating 

 the present range of greenhouses from 

 the new heating plant, and there will 

 be relatively little loss of heat, es- 

 pecially if the 'steam is carried in the 

 conduit at a pressure of forty to eighty 

 pounds, with a pressure-reducing valve 

 on the main where it enters the green-

 the return, there will be no difficulty 

 in returning the water by gravity and 

 a pressure of five to seven pounds will 

 answer. 



Even with low pressure, the loss of 

 heat by radiation will not be great if 

 the pipes are properly insulated. For 

 the main feed pipe, using low pressure, 

 the size need not be more than 4-incli,
