T have a greenhouse 21x68 feet; the sides aro yix foot hi^h with thirty-six inches of open glass, and tlie height at j^ablc is eleven and one-halt' feet. The west end of the house is glass and ex- posed. The east end is adjacent to the boiler room. I have a boiler with a .30x48-inch grate and o)ie •2\i,-im'h flow and nine IMi-inch return pipes. What are the heating requirements for the house mentioned at .') degrees below zerof H. H. W.—lud. A boiler with a pirate 30x48 inches should be capable of heating Two houses ? of the dimensions described. According to description, the house has three feet of tilass in the two side and one end wall. To heat such a house to 57 degrees when it is .> below zero, .-ibout 700 square feet of hot water radiation Avill be recpiired. This is al- togetlicr too mucli to be supplied by one l!i/a-inch flow pipe. ^Vhile fairly good results would be secured with two liVy- .inch flow pipes, it would be advisable to use three. In addition to the flow l)ipi's, use fifteen ly^-inch, or preferably twelve •_'-inch, ret'urns. To supply 700 square feet of hot water radiation, a 4-incli main flow pipe with a return main of the same size could be used. If the mains are only a few feet in length, it would be possible to use Ibinch ]iipes. Place one flow pipe on each of the side wall plates and the other four feet be
