Greenhouse Heating. 



GOOD OIL BURNER WANTED. 



I am a young florist, with one year 

 in my own greenhouses. I have been 

 burning soft coal, but find it to be much 

 trouble and dirty. I would like to burn 

 crude oil next year, but I do not know 

 ot any good burner. I have 7,350 square 

 feet of glass. Do you know of any 

 good burner? If not, will you please 

 ask the readers of The Review if any 

 florist is using the crude oil in his 

 boilers, also what kind of a burner he 

 is using? K. L. K. 



If any reader can recommend a 

 burner The Review will be pleased to 

 publish the name and address of the 

 maker. 



BOILER IS TOO LARGE. 



This summer I put in a new boiler. 

 Everyone advised me to put in one large 

 enough for present needs, with a good 

 margin, saying it would not take much 

 more fuel than a smaller one. I did as ad- 

 vised, but think it takes more fuel than 

 one which would do the work for fifty 

 per cent or more of the time. I do not 

 regret putting in the big boiler, but 

 should like to know whether I could 

 save enough on fuel to justify me in 

 installing also a smaller boiler. During 

 fifty per cent or more of the winter 1,000 

 linear feet of 1-inch pipe, with ten 

 pounds of steam, give me the required 

 temperature. Only three or four times 

 during the winter do I need the 

 maximum of about 3,500 feet of 1-inch 

 pipe. 



My boiler is a return flue boiler, 44 

 inches x 12 feet, and contains forty-six 

 3-inch flues. The grate is 45x48 inches. 

 The stack is twenty-four inches wide 

 and thirty feet high. I think the com- 

 bustion is practically perfect. Would a 

 smaller boiler be a paying investment, 

 and what percentage could I save? 



L. C. B. 



The boiler is evidently of about forty 

 horse-power and should be large enough 

 for 6,000 or 8.000 linear feet of 1-inch 

 pipe in the coils. If 3,500 linear feet is 

 all that is required in the most severe 

 weather, it would save at least twenty- 

 five per cent of the fuel if a twenty 

 horse-power boiler could be installed, 

 and perhaps fifty per cent at limes when 

 only 1,000 linear feet is needed. These 

 figures are mainly approximations, as 

 nothing is stated regarding the size and 

 construction of the house. 



It is, of course, always well to have

Hughson Regulating Valve 



In connection with a steam heating plant. Carry 40 or 

 60 pounds pressure on the boiler and set the valve for 6 

 or 10 pounds— it will do the rest. You'll b© free from 

 worry this winter, if you follow this advice: " Install a 

 HuKhson Regulating; Valve when making your 

 repairs " Ask for our Catalogue, which also shows

A SUCCESSION OF TROUBLES. 



We are having trouble in the heating 

 of our greenhouse, which is 15x20, with 

 a shed on the north end, eight feet 

 wide. When we purchased our boiler, 

 a Wilks hot water heater, 36x24, we in- 

 stalled it with an outlet connecting to a 

 pipe on each side, which formed a con- 

 tinuous circuit, with bends at the ends, 

 until they connected at the south end 

 with the inlet pipe. We placed four 

 pipes under each bench, and these, with 

 the inlet, made five under the middle
