 pipes heat the house to 58 degrees in 

 zero weather with two pounds steam pres- 

 sure at the boilers? W. J. E." 



The house heating expert of the 

 plumbers' paper says: 



"It is impossible for anyone not on 

 the ground to determine the quantity of 

 surface necessary to maintain a given 

 temperature in greenhouses, because of 

 the wide variation in the construction 

 and location. Those concerns who make 

 a business of building and equipping 

 greenhouses complete, can make very 

 close calculations as to the quantity of 

 surface required to maintain any given 

 temperature, for the reason that they 

 know exactly the construction, location 

 and exposure. Those who have had a 

 wide experience in furnishing heating ap- 

 paratus for greenhouses of various con- 

 struction and varying localities have 

 learned that two houses may be of the 

 same size and yet one may require fifty 

 per cent more heating surface than the 

 other. 



' ' Now, there are approximately 13,250 

 square feet of glass in this greenhouse, 

 and if one square foot of radiation is ap- 

 portioned to offset the cooling influence

of four square feet of glass, it would 

 give 3,312 square feet of radiation, ^or 

 7,650 linear feet of 1^4 -inch pipe. Of 

 course, this may be too much radiation, 

 but, on the other hand, we are inclined 

 to think that eighteen 1 14 -inch pipes is 

 too little. Arrangements should be made 

 with the owner to put in a given amount

 Then if the quantities are found insuffi- 

 cient, it is only fair that the owner 

 should pay for any additional surface, 

 required. In this way, he is only paying . '
