(ireenhoase Heating. 



Write the Eeview about your heating 

 troubles; state the details, giving a little 

 sketch of the way your houses are laid 

 out, and we will give you the benefit in 

 this department of the suggestions of one 

 of the best greenhouse heating engineers 

 in the country. 



THE NEEDED BOILER CAPACITY. 



Please state what capacity of brick- 

 set, return-flue boiler will be required to 

 heat, by steam, to 50 degrees in zero 

 weather, the following range of houses, 

 located in New Mexico: Four connect- 

 ed houses, 25x120 feet each, seven feet 

 to the eave line and twelve feet to the 

 ridge, with glass in one end and in the 

 sides of the outside houses to within 

 three feet of the ground; also six con- 

 nected houses, each 20x160 feet, both 

 gables glass, same height as first houses 

 mentioned. B. H. I. 



One sixty horse-power boiler, or pref- 

 erably two thirty horse-power boilers, 

 should have sufficient capacity for this 

 plant. L. C. C. 



HEATING A FRAME. 



1 should like to offer a few sugges- 

 tions in connection with the inquiry from 

 T. H., in the Keview of January 14, page 

 72, in regard to the heating of a violet 

 frame. The circulation in a hot water 

 system is almost identical with the draft 

 in a chimney. In the latter case it is 

 simply hot air rising and being replaced 

 by cold air, which may be drawn up or 

 down according to the power generated 

 by the hot air, rising in the upright stack 

 or chimney, in hot water circulation the 

 principle is the same and the drawing 

 of the return water uphill, so to speak, 

 is accomplished by the power generated 

 in the upward flow of the hot water in 

 or just after leaving the boiler or heater. 

 Therefore it is quite feasible to circu- 

 late hot water in a loop below the heater

A Positive F.ct^or^^^^ Fof Stcatn Heated Qreenhouses 



**Detroit*' Traps will keep entire system free from water at all times, making 

 every foot of heating eurface hot and efficient, returning automatically all water -of 



condensation directly into the boiler — hot — 

 and 'without a pump or injector. 



A great coal saver. 



An economical boiler feeder. 



Worth double the price. 



Ask Mr. Geo. Reinberg, flo- 

 rist, Chicago, III. He has 

 used other makes, also. 



Write us size of boiler and number of square feet of glass in your greenhouse. 

 It ■wiVL pay you.
