Greenhouse Heating. 



HEAT FOE ONE NEW HOUSE. 



Kindly advise me as to the best way 

 of heating my new greenhouse. It is 

 20x50. The side walls are five feet 

 high and consist of two and one-half 

 feet of wood and two and one-half feet 

 of glass. Each end contains two and 

 one-half feet of wood and the rest is 



flass. The height to the ridge is eleven 

 eet. There are three benches, each 

 four feet eight inches wide. I have an 

 upright sectional boiler, four feet eight 

 inches high, with a 30-inch grate. This 

 boiler now heats two houses, one of 

 them 24x50 and the other 16x62. The 

 new house is for carnations. Do you 

 think the boiler can heat all three 

 houses? If not, would it do to put on 

 another section? In one of my houses 

 there are ten 1^-inch pipes under each 

 of the side benches, and, when the fire 

 is on, the soil in those benches is baked 

 all the time. If the pipes can be so 

 arranged in the new house that there 

 will not be many under the benches, 

 I shall be thankful. The center beds 

 are solid. M. C. M. 



The letter does not give the amount 

 of glass in the side walls of the present 

 houses, or the temperature at which 

 they are kept, and as this might make 

 a difference of 50 to 7') per cent in the 

 amount of radiation needed, I cannot 

 be sure about the ability of the boiler 

 to handle it, especially as the only 

 idea regarding the rating of the boiler 

 must be taken from its grate area. A 

 boiler with a grate thirty inches in 

 diameter is generally rated at 1,500 

 square feet of radiation and upwards, 

 and as the amount of radiation in the 

 three houses is likely to be consid- 

 erably less than this, the present boiler 

 -will probably be able to heat the three 

 houses. In case the rating of the 

 boiler as given by the manufacturers 

 is not more than 1,200 square feet, and
