Greenhonse Heating, 



SuBSCEiBERS are invited to write the 

 Editor of this Department with regard to 

 any details of greenhouse heating that 

 are not understood. But please do not 

 ask The Review to make a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment advertised in this paper is, we 

 believe, the best for the trade to buy, 

 and each article the best in the special 

 field of its adaptation. 



WILL READERS PLEASE ANSWER? 



In connection with a proposed cen- 

 tral heating plant, we desire to know 

 if other florists have metered their 

 condensation of steam so that they 

 could tell the proportion of pounds of 

 steam for a carnation house per square 

 foot of glass, as we are considering 

 buying heat in this way and wish to 

 compare with present cost of heating. 

 We sometimes have a temperature of 

 25 degrees below zero.

GREENHOUSE AND RESIDENCE. 



Can I heat a greenhouse, about 15x30 

 or 15x40, from a furnace under the 

 dwelling house! Could the furnace be 

 used for heating both the dwelling and 

 the greenhouse? We have a large cel- 

 lar under the residence and it is damp; 

 so I want furnace heat and thought I 

 might use it for both purposes. The 

 greenhouse would be near the dwelling, 

 say about ten feet away. 



M. J. E. T.— Mo. 



The letter does not state what kind 

 of furnace it is proposed to use. Al- 

 though not as satisfactory as a hot 

 water or steam boiler, a coil could be 

 placed in a hot air furnace and con- 

 nected with heating pipes to be carried 

 to the greenhouse. 



I would prefer to install a hot water 

 boiler for heating both the dwelling 

 and the conservatory. The connecting 

 pipes could be carried in sewer pipes 

 under the ground and, if these were 

 properly insulated, only a little heat 

 would be lost. It will require about 

 two-thirds as many feet of 1%-inch 

 pipe to heat the house as there are 

 square feet of glass. 



PIPING A PARTITIONED HOUSE. 



Please advise me about the piping 

 of a greenhouse, 28%xl75, fourteen 

 feet high to the ridge and six feet high 

 to the plate, with four feet of 

 side glass and glass in both gables. 

 The boiler is at the center of the north 

 side of the greenhouse, which runs east 

 and west. I wish to maintain a tem- 

 perature of 56 to 60 degrees in one 

 half of the house and 48 to 50 degrees 

 in the other half, in zero weather. A 

 hot water system is to be used, with 

 the boiler top two feet below the re- 

 turn pipes. 



I should like to have the outlet pipe 

 from the boiler large enough for fu- 

 ture extension, and I should also like.

O^^ty 



The immense amount of direct self-cleaning: heating surface 

 and the thin vertical waterways cause this type of boiler con- 

 struction to heat water quicker than any other form of boiler. 



Hundreds of Florists' Review readers are using the 

 Kroeschell Boiler and mighty is their praise. The 

 past year has brought an enormous number of new 

 customers who have seen our boiler in operation at 

 other places. We attribute the large sales of the 

 1914-1915 season to the good work the Kroeschell 

 Boiler is doing everywhere. With our policy — "the 

 customer's interest first" — perfection of construc- 

 tion — factory-to-user prices — honest and "true blue" 

 boiler ratings — you simply cannot lose.
