Greenhoase Heating. 



WRONG INSTALLATION. 



[ liavo ail oast ami west ^loenliouso, 

 14x40 fret, heated by a \Vilks hot water 

 lieater. There are three benches, with 

 three lijiuch llow pipes under each side 

 bencli and four under the middle bench. 

 Tliere is one lVL>-incli return pipe under 

 each b(>ncli. Tlio boiler is about two 

 feet lower than the pipes, which grad- 

 ually rise about lifteen inches. The ex- 

 pansion tank is at the highest point. 

 This arranj^enient did not prove entirely 

 satisfactory. It Mas hard work to keep 

 the heat up on extremely cold or windy 

 days. What change would you suggest, 

 using the l^ij-inch pipe? I am planning 

 to .build a 10-foot lean-to and wish to 

 U^ 4-inch pipe. How should it be ar- 

 'ranged? E. W. G. 



If I read the description of your heat- 

 ing plant correctly, it is little wonder 

 you have difficulty in maintaining heat 

 in the house. It is installed wrong end 

 to; that is, you have too nuiuy llow pipes 

 and too few and too small returns. If 

 you will rearrange the heating plant by 

 carrying one 2-inch pipe from the boiler 

 under the ridge to the far end of the 

 house, there divide it to supply three 

 coils of li/{>-incb pipe of four pipes each 

 under each of the three benches, and 

 then reunite these near the boiler into a 

 common 2-inch return, you will have the 

 plant right end to and sufficient for a 

 temperature of 60 degrees. Connect the 

 expansion tank by a v4-inch pipe to the 

 main return within a foot of the boiler 

 and carry it six to ten feet above the 

 highest point in the heating system, and 

 note results. 



GREENHOUSE CHIMNEYS. 



There is one matter which I have sel- 

 dom se(>n mentioned in the columns of the 

 ]\EViK\v. luimely, the chimney. I have 

 an iron stack now, ami need anotlier. 

 Would a brick chimney be l)etter.' What 

 would be the inside dimensions of the 

 chimney and the thickness of the walls.' 

 J have one boiler and wish to set another 

 for emergencies. I should like to use 

 the same stack for both. Would it be 

 better to have a .separate flue for each.' 

 What height would be best ? I have a 

 hot water heater and use coke for fuel. 

 Would it be best to have a door at the 

 bottom of the stack for accumulation 

 of soot? L. Y. 



The brick cliimiu-y is more permanent 

 than the metal stack, although the ini- 

 tial cost of the chimney is much greater 

 than that of the metal stack. The gen- 

 eral rule used to determine the size of a 

 stack is as follows: The area of the 

 cross section of the stack should be 

 equal to one-ninth the area of the grate 

 surface of the boilers. If metal stacks 

 were to l»e used, we should advise putting 

 up a stack for each boiler, but if a 

 brick stack is to be employed and the 

 boilers are arranged in battery, use a 

 breeching to connect them with the main 

 stack. The area of the stack shouM be 

 one-ninth the combined area of the grate 

 surface of all the boilers to be cared 

 for. The height of the stack is a mat- 

 ter of location and the character of draft 

 desired. Tall stacks give stronger nat- 

 ural draft than short ones, but the pre- 

 vailing type of construction on large 

 power plants today is a short stSck and 



Money Saved 



Money saved in operating expenses— and at 

 the same time increasing the elliciency of 

 your plant — must be an interesting subject 

 to every florist. The installation of 



&niSteKi 



^p^ 



in your greenhouse means positive money-saving in operating ex- 

 penses. For instance, less coal. 



liAiiii liHds., Monett, Mo., testify: 



"We believe the Capitol Boiler to be the best Hoiler for KreenHouse heating 

 on the market, being easy to handle and economical on fuel. One of our com- 

 petitors has liO.OOO square feet of glass with a fioiler and used over 



SI. 000 worth of coal during the same time that we, with 1.5,000 square feet of glass, 

 with our Capitol Boiler, only used $158 worth of coal." 



This is only "ONE" of the salient advantages of CAPITOL BOILERS. Send today for our 

 descriptive cataloo, or call or write our nearest Branch or Sales Igency.
