HEATING SMALL PLACES. 



In a previous installment, published 

 April 18, various phases of hot water 

 systems for heating greenhouses were 

 discussed. The hot water method is so 

 much to be commended for small places 

 that we will take up the consideration of 

 some of the other points: 



Expansion Tank. 



The expansion tank oonuected with 

 such a system is located over the boiler 

 above the highest point in the system. 

 This tank is connected by a pipe to the 

 return main and also to the water sup- 

 ply. It is equipped with a glass water 

 column and an overflow pipe leading to 

 some outside drainage. The object of 

 this expansion tank is to prevent the 

 waste of water by overflow, and hence 

 to save fuel and hot water. In appara- 

 tus of this description water heated, say 

 from 40 to 212 degrees will expand 

 about one-twentieth of its volume, and 

 unless an open expansion tank is pro- 

 vided the waste through overflow will be 

 considerable. 



Good Greenhouse Heater. 



A good, effective boiler for green- 

 house work should have a coal area of 

 about fifty per cent larger than that of 

 the grates, which is essential for main- 

 taining a proper temperature during the 

 cold winter nights. Anything short of 

 this amount of space may cause trouble 

 at critical moments. The firebox should 

 be tinusually deep to provide ample space 

 for good combustion of the gases, and 

 the fire channels over the fireboxes to 

 the boilers should incline toward the fire, 

 so as to direct the heat directly against 

 the boiler surface. The concentration of 

 the fire in a series of currents thus pro- 

 duces more force than if scattered. 



The firebox should pf operly be con- . 

 nected with the smoke pipe so that no 

 smoking or back-draft can follow. By 

 means of a wide U-shaped flue extend- 

 ing a considerable distance parallel with 

 the boiler a good part of the escaping 

 heat is utilized in heating the water. 



The grates should be of ample size 

 and designed to receive and hold a good 

 bed of coals, and when cleaned be sim-

FLORENCE HEATERS 



When most push nipple boilers need 

 repairing, you have to take the whole 

 boiler apart; you do not have to do this 

 with the Florence Heater, as each sec- 

 tion forms its own base. This does away 

 with the "separate base," and enables 

 you in making a repair to take out any 

 one section desired, and simply draw 

 the boiler together again, with but a 

 slight loss of time and almost no trou- 

 ble. 



Another feature of the Florence is 

 that it is so conservatively rated that the 

 difference in the capacity of the boiler 

 when running under this condition would 

 scarcely be noticeable, enabling you to 

 get along until repairs arrive. 



As a matter of fact, Florence Heat- 

 ers, on account of their superior con- 

 struction, are not ordinarily subject to 

 strains in the weakest point, which break 

 so many heaters; consequently purchas- 

 ers are relieved of the great expense for 

 repairs so common with most of the 

 present-day heaters.

pie of operation. The loosening and 

 discharging of clinkers without any 

 great skill is an important consideration. 

 Without properly designed grates the 

 heater never will give satisfaction, and 

 all the improvements made in other 

 parts of the plant will be nullified. 



What Makes Circulation* 



The application of the principle of 

 hot water circulation to greenhouse heat- 

 ing is due to its adaptability. In in- 

 stalling such a plant it must be remem- 

 bered that it is gravity which produces 

 the circulation of the water through the 

 system. It is the difference in the 

 weight between ascending and descend- 

 ing columns of water in the perpendic-
