TRAVIS GREENHOUSE ROCKER GRATES 



For hard, continuous, economical firing, with a small amount 

 of attention, use the Travis Rocker Grates. It is no longer 

 necessary to experiment with rocker grates. Your neighbor can 

 tell you what make of rocker grate he has and you can quickly 

 decide where you can get a rocker grate that will, or will not, 

 answer your purpose. Let us send you names of customers who 

 are now using our grates. The best advertisement is a satisfied 

 customer. We want our grates to tell their own story. We have 

 proven to many greenhouse operators that they have been wasting time, patience and fuel, while using eittier stationary or poorly 

 constructed rocker grates. There is nothing gained in neglecting your grates, which are the vital point of your range. Every cold 

 winter night your mind is centered on your fire. What is the condition of your grates? Can you control them? We guarantee 



that you will feel confident of getting the very best results obtainable when using our grates... _.^ i.

Greenhouse Heating. 



Subscribers are invited to write the 

 editor of the Heating Department, de- 

 scribing their troubles or asking any 

 questions regarding the heating of green- 

 houses, the piping or boiler-room. But 

 please do not ask us to make a choice of 

 apparatus for you. Each boiler adver- 

 tised in The Review is a good boiler, and 

 the advertisers sell them on their merits. 



SIZE OF BOILER. 



Kindly let me know what would be 

 the necessary horse-power of a tubular 

 steam boiler to heat 25,000 square feet 

 of glass here, in central Illinois. 



E. R. 



The size of the boiler will vary with 

 the temperature desired. While one 

 rated at fifty horse-power would answer 

 when 45 to 50 degrees is needed, it will 

 be advisable to have at least sixty 

 horse-power if a temperature of 60 de- 

 grees is to be maintained, and the ca- 

 pacity of the boiler should be propor- 

 tionately increased for higher tempera- 

 tures. ' 



AMOUNT OF RADIATION. 



Will you kindly let me know the 

 number of square feet of radiation re- 

 quired for a plant house having ap- 

 proximately 5,000 square feet of glass? 

 The house measures 40x60 and the ridge 

 is about twenty-five feet above the 

 floor. Steam heat will be used, under 

 about five pounds of pressure. The pip- 

 ing will consist of wrought-iron pipe 

 coils, made of IVt-inch pipe, with the 

 coils one pipe high. A temperature of 

 70 degrees inside is desired, and this 

 should be maintained when the outside

will add to the ef- 

 ficiency of Your 

 Heating System 

 and Reduce Your 

 Coal Bills. 



To keep steam coils 

 drained of condensation 

 leaves full area of pipes 

 for the transmission 

 of heat — hence more 

 efficient heating sys- 

 tem. To automatically return that con- 

 densation directly to the boiler before its valuable heat is lost 

 makes for a more efficient boiler. "Detroit" Traps do both. 

 Bulletin No. 326- WF tells how it is done. Yours upon request.
