HEAT FOR A FERN HOUSE. 



We have a carnation house 21x100, 

 heated by hot water. We wish to change 

 it to a fern house, after puttying and 

 lapping the glass. It is heated by two 

 4-inch flows and ten li^-inch returns, 

 five on each side. There is a board wall 

 four feet high on each side. The height 

 from the ground to the ridge pole is ten 

 and one-half feet. We are now just able 

 to keep the temperature at 60 degrees 

 with the ventilators closed. What addi- 

 tional piping will be required for zero 

 weather f We are located in Utah. 



F. E. W. 



The piping described should be sufii- 

 cient to maintain a temperature of 50 

 degrees in zero weather. If 65 degrees 

 is desired, it will be well to add four or 

 five 2-inch pipes. If 60 degrees will- 

 answer, the addition of three 2-inch pipes 

 will prove sufficient. 



CAPAQTY OF BOILER. 



I have several greenhouses, measuring 

 seven feet to the gutter and comprising a 

 total of 77,240 cubic feet of space, from 

 floor to ridge. I am heating this with 

 one horizontal tubular boiler, fourteen 

 feet by forty-eight inches, and containing 

 twenty-seven 4-inch flues. The grate sur- 

 face is 4x4 feet. There is a good brick 

 stack, with splendid draft. I aim to carry 

 ten pounds or less. 



I have added to my range two new 

 houses that contain 62,200 cubic feet of 

 space. These are built with concrete side 

 walls and will be as tight as putty, glass 

 and brains can make them. The total ex- 

 posed glass surface of the whole range, 

 including the ends, one side and the roof 

 will be about 18,000 square feet. Can I 

 safely heat this to an average of 56 de- 

 grees with the one boiler, in this Missouri 

 climate! W. J. B 



From the dimensions given, the boiler 

 can be safely rated at forty to forty-two 

 .o^X?^t^- ^* *^« outside figure, 2,800 

 to 3,000 feet of radiation would be re- 

 quired. There should be no difficulty, 

 therefore in heating the houses in ques- 

 tion, BO far as the size of the boiler is 

 concerned.
