Two flows and ten returns should answer tot the lean-to, unless there is glass in the outer wall. GOOD AND BAD CONNECTIONS. I am installing a hot water heating system in a greenhouse 30x100. The boiler pit is at the west end of the house. I am using 4-inch pipe for the main flow leturn. I shall uao a gravity system and I intend to connect the expansion tank to the return where it connects with the boiler. The tank will be ten feet above the boiler. I in- tend to run one S^^-inch flow and one 3-inch flow to the east end of the house, one on each line of pipe posts, connect- ing these flows at the east end with six 2-ineh returns on each side of the house. The return coils will drop back to the west end, where they will con- nect with the 4-inch return pipe. Would it be advisable to connect the flows with the return coils at the west end of the houst; also, and put valves in the branches that would be used to make the connection, or would it be best to make only the one Connection between tha flows and the return coils, at the east end of the house t M. W. B.—Kan. Nothing will be gained by connecting the flow and return pipes at the west end of the house, as proposed. On the other hand, while it would make no difference whatever so long as the valves are closed, whenever the valves are open it would tend to hinder the circulation in the coils. In this hindrance we can see no object to be attained, unless it is to reduce the heat given out by the coils, and this can be done by closing the draft and opening the fire door of the heater, if necessary. We can see nothing in particular to criticise in the plan outlined for in- stalling the piping, although we would connect the expansion tank to the high- est part of the main flow p
