Greenhouse Heating. 



CAPACITY OF BOrLEE. 



I have a tubular boiler, of locomo- 

 tive type and containing seventy-five 

 square feet of heating surface. At 

 present it heats a house 16x50 feet, 

 used for a general stock of pot plants. 

 How much more glass will this boiler 

 handle, at carnation temperature, in 

 this Ohio climate? C. C. M. 



In a house 16x50 feet a tempera- 

 ture of 50 degrees can be secured with 

 250 square feet of radiating surface 

 if hot water is used, and 150 square 

 feet if the house is heated with steam. 

 For a temperature of 60 degrees the 

 amount of radiation should be increased 

 nearly one-third. With conditions 

 fairly favorable, a boiler of the size 

 mentioned should be able to heat 

 nearly twice your present amount of 

 space to the temperature required for 

 carnations. 



CRUDE OIL AS FUEL. 



I always appreciate the information 

 to be found in The Review and I wish 

 at this time to ask a few questions 

 on a Subject that is of interest to 

 many florists on the Pacific coast. Can 

 crude oil be profitably used as fuel 

 where the heating of greenhouses is 

 done by the hot water system and 

 where the cost of cord-wood is, on 

 the average, $5 per cord and the price 

 of soft coal is $6 to $9 per ton? About 

 how much oil represents the equiva- 

 lent of a cord of wood or a ton of 

 average soft coal? "What would be 

 the average cost of installation of oil 

 burners in a Great Northern boiler, 

 46 by 56 in. by 12 ft.? 



Electric power is obtainable. Would 

 it be possible or of advantage to use 

 compressed air as a substitute for 

 steam and have an electric motor to 

 furnish the pressure for spraying the 

 oil? Would such an installation pay 

 in a range which contains only 10,000 

 square feet of glass? Oil can be had 

 for $1 per barrel. I am located in 

 northwestern Oregon. J. G. B. 



To get the best results with crude 

 oil, it is usually necessary to connect 

 the burner with a steam jet. At the 

 prices given for wood and coal, crude 

 oil would be found an economical fuel 

 at $1.25 to $1.50 per barrel, and at 

 $1 per barrel it would, of course, be 

 materially cheaper. 



With electrical power, the use of

This book tells how to make 

 permanent repairs to boilers, 

 tanks, piping, etc., and how 

 to make greenhouse iron pipe 

 joints, using the well-known 

 Smooth-On i r on cements. 

 Every florist should have a 

 copy at once.
