Greenhouse Heating. 



Subscribers are invited to write the 

 Editor of this Department with regard to 

 any details of greenhouse heating that 

 are not understood. But please do not 

 ask The Review to make a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment advertised in this paper is, we 

 believe, the best for the trade to buy, 

 and each article the best in the special 

 field of its adaptation. 



USING MOSTLY TWO-INCH PIPES. 



I expect to build two connected green- 

 houses, each 23x110, and five feet high 

 to the gutters. The houses will run 

 east and west and there will be two feet 

 of glass in the south wall. The roofs 

 will be three-quarter-span. I have a 

 lot of sashbars on hand, ten and one- 

 half feet long, for one side; what length 

 of bars will be needed for the other 

 side? Also state the size of pipes and 

 the number needed to heat the houses 

 to 55 degrees in this Ohio climate. As 

 I have a lot of 2-inch pipes, I should 

 like to makes use of them. "Would it 

 be satisfactory to have the returns on 

 the sides, under the gutters of the 

 houses? A. T. 



For a three-quarter-span house, twen- 

 ty-three feet wide, with sashbars ten 

 and one-half feet long for the north 

 side, it would be well to use bars six- 

 teen feet long for the south side. 



To heat a house 23x110 feet to 55 

 degrees in zero weather, use four 2-inch 

 flows and eight 2-inch returns. The 

 flows can be placed on the walls near 

 the plates and the returns can be car- 

 ried underneath, with the coils so ar- 

 ranged that each flow will supply two 

 returns. If the houses are much ex- 

 posed, it would be well to use one 2^^- 

 inch flow pipe in the south house, which 

 has two feet of glass in the outer wall, 

 and run one extra return, making one 

 21/^-inoh flow, three 2-inch flows and 

 nine 2-inch returns in this house. 



STEAM HEAT FOR ONE HOUSE. 



I should like to know what is the 

 best and cheapest way to pipe my house 

 for steam. What size of pipe will give 

 the greatest percentage of heat? Many
