Florence Constrnctioo. 



There has been no change in the 

 d'sign of the FLORENCE since it was 

 jijst created. There have been, of course, 

 i iprovements and modifications, but 

 ro change in the principle. 



It is so perfect now that we don't 

 i.elieve it can be improved, but if it can, 

 :i, will be done. We don't beheve in 

 {-•eakish things or marvelous things, 

 . iid for this reason, the FLORENCE 

 l.as never swerved from its standard of 

 ( xcellence, save to grow better as science 

 jiows the way. 



FLORENCE HEATERS are man- 

 ufactured at Belvidere, 111., by the 

 Columbia Heater Co., where their main 

 otiice is also located. The Chicago Sales 

 Department is located at 36 Dearborn 

 St., Chicago, where you are cordially 

 invited .to inspect their samples on 

 exhibition. 



1907 catalogue will be promptly 

 mailed to you from either of the above 

 addresses.

Such estimates are modified somewhat 

 by the character of the greenhouse it- 

 self, such as shape and dimensions, and 

 whether constructed of brick or wood, 

 single or double-boarded, and also the 

 direction in which the greenhouse faces. 

 All of these factors modify the condi- 

 tions, so that the engineer must make 

 his calculations for the size of the boiler 

 required upon exact facts. The nature 

 of the fuel intended for use is another 

 point that must be considered, for 

 where soft coal is to be burned a larger 

 boiler is generally recommended than 

 for hard coal. The proper siding and 

 construction of the greenhouse insures 

 protection from cold outside drafts, so 

 that the heating is much easier arranged. 



Kind of Boilers. 



For small houses the ordinary round 

 boiler answers all purposes, and owing 

 to its cheaper cost, is most popular; but 

 for large houses sectional steam and 

 water boilers are necessary. A cast- 

 iron sectional boilet. properly made and 

 of the right dimensions gives satisfactory 

 results. They are safer, more durable, 

 and more economical for this kind of 

 lieating than common wrought-iron or 

 i^teel tubular boilers. If properly de- 

 >*igned they can be set independent of 

 brick-work and in such a way as to oc- 

 <upy less space. These considerations 

 liave made this type of boiler popular, 

 !>ut special steel boilers are largely used. 

 A boiler for a greenhouse should be 

 simple in management and capable of 

 •naintaining a steady temperature from 

 ight to ten hours without attention. It 

 also should be economical in operation 

 ;ind cost of repairs, and every part easy 

 of access for cleaning. The man running 

 •'' commercial greenhouse can not em- 

 I'loy an engineer to look after his hot 

 ''vater or steam plant, and he is not gen- 

 'Tally much of an engineer himself. For 

 *his reason the plant must be laid out on 

 f'iniple lines and with as few technicali- 

 ties as possible. The boiler must be 

 largely automatic in its operation.

Methods of Piping. 



The layout and dimensions of the 

 mains and radiating pipes should be so 

 as. to distribute the heat economically 

 and uniformly. It is fatal to a green- 

 house to have one part overheated and 

 another part underheated. A good deal 

 of the result will depend upon the size 

 and direction of the mains so as to keep 

 up an active circulation. The open tank 

 hot water apparatus probably gives the 

 best results. In a properly constructed 

 plant the entire control of the heat 

 should be regulated by the draught 

 damper on the boiler after the pipe 

 coils have once been heated. The fire 

 should be increased or decreased by the 

 draught regulator, so that the tempera- 

 ture can be made to suit any weather. 

 By means of the chimney draught the 

 temperature of the greenhouse is in- 

 creased or decreased automatically. 



In the open tank system of hot water 

 heating for greenhouses the dimensions 

 of the boiler are first made to suit the 

 needs of the house, or of such size as 

 necessary to heat the amount of radiat- 

 ing surface estimated essential for a 

 given space. The boiler is connected at 

 the bottom and top with the flow and 

 return mains, and branches are taken 

 from the mains to the coils of radiating 

 pipes. In the pipe header there should 

 be placed an automatic air valve which 

 will permit the air which accumulates in 

 the pipes to escape.
