( >jrn CUI/l'UlUL ESTABLISHMENT, KING'S EO AD, 'CHELSEA. 



THE WHOLE HEATED BY ONE BOILER. '. '. 



THE LY.S rTHENKD <>TICE of this Establishment, which appeared in the Gardeners 9 Chronicle of December 16, 1854, directed the attention of the Horticnlfom 

 iswi til* imit lmnroT«meiit* m*l« bf Meisro. Wekkb & Co. in the method they have recently adopted for heating it, and in order to give some idea of the character of the Establig^ 



whose distance from town a^T^ 



to numerous Correspondents 

 admit of their personally inspectin 





town do* M 

 it at present, the adjoi^ 

 sketch has been made, and the following observations *i^> 

 respectfully submitted to them and all others interest^ j, 

 Horticultural proceedings. 



This Establishment is now the most complete of any i n ^ 

 country, consisting of Conservatories, Greenhouses, Hotbo^ 

 and several Pits, with top and bottom heat, all appropriate* 

 their several purposes. 



Until very lately there were six boilers of various sizes, but iij 

 on the same principle, employed here to heat the difim 

 Houses and Pits, and although those boilers were fonnd boft 

 efficient and economical during eight years, each doing thr» 

 times more work than the common description of boiler, reetu 

 improvements convinced Messrs. Weeks & Co. that higfak 

 important results were attainable by substituting one boiler, of 4 

 similar construction, for the six; and now, the whole of th» 

 extensive establishment is heated effectually by ONE bob 

 5 feet high by 3 feet 6 inches in diameter, exposing to the iim*. 

 diate action of the lire a surface of 340 feet, superficial. The 

 expense attending this great alteration of connecting all tht 

 pipes of the various houses and pits to one boiler will be fofly 

 repaid in one season. The boiler is fed from the top, which it 

 nearly on a level with the surface of the surrounding ground, bat 

 there are furnace doors, and the usual openings in the brickwork 

 below, from which it is cleared out, and to cause a draught. The 

 glass-houses, which maybe said to be built round the four sides if 

 a long square, or parallelogram, which has a gentle rise to theeoi 

 farthest from the boiler, are certainly well placed for being ill 

 warmed from one boiler, which is effected as follows :— The boik 

 is placed at, say, the right-hand corner of the square. A 4-iock 

 flow pipe is led in a straight line from it on the same side totk 

 bottom of the square, or as far as there are houses, and the retail 

 pipe is brought back to the boiler in the same drain immediately 

 l>elow it. Another main 4-inch flow and return pipe is taka 

 through the show houses and down the other side of the square,! 

 furnish means of heating the houses on that side, and from then 

 two main pipes all the houses are warmed by connecting the pipe 

 which are carried round them with the two main pipes just me* 

 tioned, which are also made to pass through as many houses ft 

 lie in their way ; and in order that the heat they contain nwrk 

 turned to as good an account as possible, the drains in which thr? 

 are placed have been covered, inside the houses, with neat iis 

 gratings, which permit the warmth to pass through into t!» 

 houses. 



The whole of the several Houses and Pits can be heated ate* 

 time, or separately, with a full command of heat, and an? p* 

 regulated at pleasure. 





W 



If the 1 is and Pits w o placed in a line, they would ex- 

 tend about 1000 feet, exposing to the atmosphere upwards of 

 16,000 superficial feet of glass. The water circulates in tiv 

 various Houses and Pits through 5000 feet of pipe. 



An experience of upwards of thirty-six years as Ilorticultari! 

 Builders, and Hot Water Apparatus Manufacturers, harfc 

 afforded Messrs. Weeks & Co. constant opportunities for effecting 

 important practical improvements in Building and Heatinf, 

 induced them to build their present Nursery, so that the Nobility 

 and Gentry about to erect Horticultural Buildings, might haw 

 the means afforded them of inspecting an extensive variety of 

 Horticultural Houses and Pits with the Heating Apparatus to 

 full operation. 



The ^^^^^^7^ economy of the heating apparatus will perhaps be better understood by the following comparison of the work it does in Mean.
