Greenhouse Heating. 



. One of the evidences of the wide read- 

 ing given the Heating Department of The 

 Review is the receipt of a heating query 

 from a florist in Denmark. 



BOILEB ON GROUND LEVEL. 



We have a greenhouse 32x100 feet. 

 The sides are of 10-inch double-flue 

 tile and are four and one-half feet high. 

 There is a double roof. We wish to 

 extend the house seventy-five feet and 

 place the boiler between the two houses. 

 What size of common flue boiler would 

 be the most economical to use? How 

 many runs of 1-inch or 114-iiich pipe 

 will be required to heat the house to 

 65 degrees in zero weather? 



Would it be practicable to have the 

 floor of the boiler room on a level with 

 the greenhouse floor? We have a re- 

 turn trap to force the water into the 

 boiler. Could we set the trap at the 

 side, on a level with the boiler, and 

 have it work satisfactorily with less 

 steam? We are located in northeastern 

 Ohio. M. G. C. 



To heat the house described to 65 

 degrees in zero weather, it will be ad- 

 visable to use two 2-inch flow pipes 

 and fifteen IVi-inch returns. The boiler 

 can be placed on a level with the floor 

 of the greenhouse, provided arrange- 

 ments can be made to return the wa- 

 ter, and the trap can also be at the 

 same level under the same conditions, 

 but the pressure required will be even 

 higher than when the boiler and trap 

 are below the level of the floor. Most 

 of the traps would work with five 

 pounds of pressure and some with even 

 less. 



While a t w e n t y-fi v e horse-power 

 boiler would heat the houses described, 

 if further additions are to be made 

 they should be provided for by put- 

 ting in a somewhat larger boiler at 

 this time. 



IN MARYLAND CLIMATE. 



I have been a subscriber to your pa- 

 per for a number of years, and now 

 that I am building a new greenhouse I 

 write to ask your opinion in regard to 

 heating same. This house will be 30x85 

 feet, height of side walls five feet, with 

 two feet of glass and two and one-half 

 feet of concrete. The height from the 

 ground to ridge pole is fourteen feet 

 three inches, and the glass used will be 

 16x24, double, exposed on all sides, no 

 sheds adjoining. I have in use a Fur- 

 man sectional hot water boiler. I wish

The Standard 

 Steam Trap 



Ib acknowledged tl:e best for the 

 florist, because it is durable and does 

 its work without trouble and annoy- 

 ance, saving its cost by the economy 

 in coal bills.
