With three flows one is generally located under the ridge. For the two larger houses, three 2^4- inch flows are desirable, but two will answer in the other house. Instead of arranging the main flow pipes as de- scribed, it will be better to carry them up to a point about one foot below the ridge and then to run them toward the houses. Take off two 2 V^-inch flow pipes and drop them down to run along the eave plates. Then reduce the size of the flow to two and one- half inches and carry it along under the ridge of the longer houses. If three 2-inch returns are connected with each of these flows, a temperature of 50 to 55 degrees can be obtained. In reference to the other house, it would appear that the ridge in the connect- ing shed is not more than six feet high. If head room will still be allowed, either one 3-inch flow pipe or two 2^4- inch flows can be run under the ridge, or one 2i4-inch flow pipe can be car- ried upon each eave plate. For the main part of the house use one 2V^- inch flow under each eave plate and connect these with four 2-inch returns. After they reach the connecting shed the number of returns on each side can be reduced to two. SIZE OF COIL HEATEB. Will you please tell me how many feet of 2-inch pipe will be needed in a coil heater to supply 150 feet of 2-inch pipe used as radiation? I am located in Kansas. L. C. B. While the amount of pipe needed would vary with the way it is arranged in the heater, it will be advisable to use about twenty feet of 2-inch pipe in the heating coil for 150 feet of pipe in the radiating coils. For larger amounts of radiation the proportionate amount would be reduced nearly one-half. STEAM FIFES ON INCLINE. We are
