Greenhouse Heating. 



One of the largest concerns supplying 

 Pocahontas coal to florists, and it is the 

 favorite fuel with many growers, gives 

 it as its opinion that the labor troubles 

 that are imminent in the coal trade will 

 be rather long drawn out. 



HEAT FOR FLORIST'S DWELLINa. 



Will you kindly inform me what size 

 of radiators, or how many square feet 

 of radiation, will be required to heat 

 two rooms in my dwelling, adjoining 

 the greenhouses? I am using overhead 

 mains. Will special radiators be need- 

 ed? The water in the boiler is most of 

 the time at 180 degrees and I want a 

 temperature of 70 degrees in both rooms 

 when the outside temperature is 25 de- 

 grees below zero, the coldest we had 

 this winter. The two rooms have no 

 doors leading to the outside; they have 

 8-inch cement walls, plastered outside 

 and finished inside with siding all over. 

 One room is eleven feet long, six feet 

 wide and eight feet high; it has one' 

 window, 21/2 X 5 feet. The other room 

 is eleven feet square and eight feet 

 high; it has two windows, each 2V^ x 5 

 feet. There is a connec|;ing door be- 

 tween the two rooms. There are other 

 rooms in the rear of these two rooms. 



H. S. 



The amount of radiation depends to 

 some extent upon the amount of wall 

 surface exposed to the outside air. The 

 arrangement of the rooms is not quite 

 clear, but supposing that each of the 

 rooms has two walls exposed, and that 

 the rooms to the rear are heated, it 

 should be possible to heat the smaller 

 room, 6x11 feet, by using a radiator 

 containing forty square feet of radiat- 

 ing surface. The larger room should 

 have sixty-four feet of radiation. 



DEEPEN THE BOILER PIT. 



A short time ago I wrote to you ask- 

 ing for information on the heating of 

 my greenhouse. However, I did not give 

 as full particulars as I might and a 

 brother florist has advised me to write 

 again, giving more explicit details. I 

 have run the steam system for two 

 winters and have not got satisfactory 

 results. My boiler, I think, is large 

 enough, but perhaps there is not enough 

 pipe for radiation. When I build a 

 larger place, I shall probably install a 

 hot water system, but I must use the 

 steam system for the present. My green- 

 house is 12x60 feet, six feet high to the 

 eaves and nine feet to the ridge. It 

 has an even-span roof. The house runs 

 east and west. The gables are glass 

 and there is a foot and a half of glass 

 in the south wall. The required tem- 

 perature is 60 degrees when the outside 

 temperature is zero. 



The boiler is of the round, upright 

 type, for steam, and is six horse-power. 

 It contains thirty 2-inch flues, three

WHAT THE USERS SAY 



Better than All Others 



I have flred boilers for the last forty years. Th* Kro«sch*ll Is th*Ib*st I hav* •v«r 



us«d. I have two cast iron boilers, also a locomotive boiler coupled with yours, but did not 

 need to use the cast iron boilers this winter. Your No. 7 boiler is rated at IS.OOO sq. ft. of 

 class and carries 25,000 sq. ft. of glass until the outside temperature goes down to 10'' of 

 frost. We have no trouble to keep temperatures in our houses with easy firing since we in- 

 stalled your boiler. From the boiler to the farthest end of our violet houses and return is 800 

 feet, and circulates very quickly. The Saltfoed Flower Shop.

More Heating Surface

and less water space than 

 is contained in any other 

 boiler. (Note the many 

 flues set close together.) 

 This is one reason why 

 the users of the 



"^Superior Standard" (ireenhoiise Boflers 



find them perfectly satisfactory. We frequently receive re-ordera 

 from florists who have tested these boilers thoroughly and found 

 them even " Superior" to our claims.
