IT PAYS 



TO USE- 



ELASTIC FIRE BRICK 



Any Handy Man Can Install It. 



In All Your 

 Boiler Work 



Use it for patching when you cannot afford to cut a boiler out. 

 ELASTIC FIRE BRICK can be used for all fire brick purposes. 



Hocrber Bros., Geo. Wittiiold Co., Miller Bros., C. Haasermann, John Reading and Broadbeck the Florist 

 are using Elastic Lining. These are only a few of the thousands we are selling.

returns in each of the three coils. We 

 should not attempt to heat the house 

 with less than eight returns, in addition 

 to the three flows suggested above. This 

 would provide three returns in each 

 wall coil and two in the center of the 

 house, and we are confident that for the 

 above temperatures it will make a con- 

 siderable saving both in the firing and 

 in the amount of coal consumed if an 

 additional return is placed in the south 

 coil. Of course, if it will answer to 

 allow the temperature to drop to 50 de- 

 grees in severe weather and it will only 

 reach 30 degrees below zero a few times 

 during the winter, the additional re- 

 turn will not be required, but we should 

 feel safer if nine 2-inch returns are 

 used. 



While not over 250 square feet of 

 radiation will be needed, we should use 

 a boiler rated for 450 square feet, with 

 a grate at least twenty inches in diame- 

 ter. A good boiler with a grate twenty- 

 five inches in diameter would heat two 

 houses like the one described. 



DOUBLE HOUSE— ABOUT HEATING. 



I am sending a diagram of the two 

 houses we are about to build. There 

 is no wall between the two, and we 

 intend to use hot water heat. Have we 

 the flows and returns placed right? 

 What size of boiler should we use with 

 this arrangement? II. V. G. G. — 0. 



From the sketch we learn that the 

 houses are 21x50 feet, with thirty 

 inches of glass in the exposed walls. 

 A temperature of 40 degrees is desired 

 in zero weather. 



The sketch also shows the proposed 

 piping to consist of three 2-inch flows 

 in each house. Two of the flows are 

 on the wall plates and the other three 

 feet below the ridge. The returns arc 

 in three coils, each consisting of three 

 114-inch pipes. 



Good results will be secured from the 

 arrangement suggested. The piping will 

 provide the needed radiating surface 

 and it is properly distributed. There 

 should be no trouble in securing a good 

 circulation in the I'i-inch returns 

 when the coils arc less than fifty feet 

 in length, provided the top of the heater 

 is well below the level of the returns, 

 and we should favor the use of pipe of 

 this size under the above conditions 

 if it is on hand or can be obtained 

 cheaper than a larger size. However, a 

 little better circulation could be se- 

 cured with 114-inch pipes and only 

 eight would be required in each house. 

 Of these, throe could be on each of the 

 outer walls. 



Although only about 550 square feet 

 of rndiation will be needed in the two 



What Prominent Growers Think 

 About the Standard Recording Thermometer 



Erie, Pa., Dec. 16, 1919. 

 "Please send us another of those ther- 

 mometer cJocks, just like the one you 

 sent us about two weeks ago. We 

 would never be without one again."

The actuating element of the Standard Record- 

 ing Thermometer is of lamina metal, which, be- 

 sides being extremely sensitive to temperature 

 changes, is practically indestructible. Record 

 charts are furnished either daily nr weeVly, and 

 the whole mechanism is contained in an attractive 

 metal case fitted with lock and key, which insures 

 ^^^^^^ the record from being tampered with.
