PIPING NEEDS READJUSTMENT. I have three connected greenhouses, each 22x75 and eleven feet high to the ridge. There are two feet of glass and three feet of boards iu the side walls. The south end of the houses is glass; the north end adjoins the workroom. I should like to keep a temperature of 60 degrees in zero weather. At pres- ent there are in each side house six 2-inch flows and seven 2-inch returns, and in the middle house three 2-inch flows and three 2-inch returns. The boiler is large enough, but I could not maintain a temperature of 54 degrees in cold weather, though the water in the boiler was at 242 degrees. Kindly tell me whether there is sufficient ra» diation in the houses for this New York climate. If not, how much addi- tional piping will be required? A. H. For heating the houses with hot water, using an open tank system, the radia- tion is insufficient, and the addition of three returns in the outside houses and six in the middle house would be neces- sary to maintain the femperature de- sired in the coldest weather. It is stated, however, that a temperature of 242 degrees in the boiler will only main- tain 54 degrees, from which it is evi- dent both that the system is a closed one and that the circulation is ex- tremely pooV, as with the water in the boiler at 242 degrees there should be no difficulty
