LARGE PIPE. 



Please inform me how many running 

 lengths of 4-inch cast-iron pipe, in hot 

 water heating, will be required for a 

 house 20x50 feet, which I intend to erect 

 this summer. The boiler will bo below

tively sheltered location, eight lines of 

 4-inch pipe should be sufficient to main- 

 tain a temperature of 55 degrees during 

 the coldest weather in your Michigan 

 climate. It would be desirable, however, 

 to have at least ten lines of pipe, five 

 along each side and running part way 

 across the end of house not protected

STEAM OR HOT WATER HEATING. 



Which is the better system of heating 

 a greenhouse, steam or hot water? I 

 want to install a boiler and am at sea as 

 to which to get. I have two houses, one 

 20x75 and the other 12x60, with 4-foot 

 walls and 7-foot ridges. "Would I require 

 as much pipe for steam as I would for 

 hot water? The average temperature 

 here (state of Washington) last winter 

 was 12 degrees above zero, the coldest it 

 has been for years. I cannot very well 

 use a pit, for the water is too near the 

 surface; so I would have to place the 

 boiler on the surface. One house stands 

 east and west, the other north and south, 

 on the sides of a square. C. J. J. 



The only satisfactory method for heat- 

 ing your houses will be by means of hot 

 water. Secure a boiler of a low, hori- 

 zontal type and set it just as low as 

 possible. For the 20-foot house carry a 

 21/^ -inch flow pipe from the top of the 

 boiler along under the ridge of the house 

 to the farthest end; then drop below the 

 benches or along the side walls and di- 

 vide into eight 2-inch returns, four on 

 each side. For the 12-foot house provide 

 one 2-inch flow pipe and six 1^-inch re- 

 turns. The expansion tank should be lo-
