(ireeDhoase Heatiog. 



A THERMOSTAT is SO inexpensive that 

 hardly any greenhouse owner can afford 

 to be without one. 



It is September 1 and those who have 

 not already looked to their season's sup- 

 ply of coal are beginning to ' ' sit up and 

 take notice. " 



Coal has been boosted another 10 

 cents per ton. It is reported that a num- 

 ber of the Illinois operators have capitu- 

 lated to the miners' demands and that 

 work is being resumed. This is apparent- 

 ly substantiated by the fact that there 

 are fewer idle coal cars than at any time 

 since spring. The indications point to 

 a car shortage that will far surpass that 

 of last winter and it behooves the flo- 

 rists, who do not want a freeze-up this 

 winter, to buy now. 



HEAT FOR RESIDENCE. 



We want to heat our residence from 

 our greenhouse boiler, and should like 

 to know what size of flow and return 

 will be necessary, Jibing water und<j^ a 

 generator pressure. The dwelling, whi(*li 

 is 100 feet from the boiler, contains 

 four rooms fifteen foet square and two 

 rooms 6x15 feet. How should the flow 

 and return be protected in the ground, 

 in this Indiana climate? What size of 

 radiator is necessary to heat a room 

 fifteen feet square to 70 degrees in 

 zero weather? The house is of frame 

 construction and nearly flEew, with build- 

 ing paper under the drop siding and a 

 solid concrete foundation. 



M. A. B. 



The amount of radiation would vary 

 considerably with the height of the 

 room and the amount of exposed glass. 

 An average for the larger rooms de- 

 scribed would be about sixty square 

 feet of radiation. A simple way of de- 

 termining the amount required in a 

 dwelling, with hot water heat, is to take 

 one square foot of radiation for each 

 square foot of glass, one square foot

Mr. Florist, if you were shown: 



That by the installation of a good tilting steam trap 

 you would effect a saving in fuel sutlicient to pay for 

 the trap in from three U) six months. 



That you would increase the otticiency of your 

 steam lines by draining them of all condensation. 



That this pure hot condensation could be returned 

 to the boilers a.s ftvd water by means of this trap 

 withouUthe assistance of pump or injector. 



Would it not be a matter of considerable import to you ? 



The MOREHEAD Tilting: Return Steam Trap will do tliis and more.

Is acknowledged the best for the

 Its work without trouble and annoy-
