TVO VIRGINIA ROSE HOUSES. 



On page 74 of the Eeview of February 

 4, I read the inquiry o5 D. G. G. and 

 the answer, and i wish to take the lib- 

 erty of disagreeing with the instructions 

 given. As the heading says "Two Vir- 

 ginia Rose Houses," I do not think it 

 would be necessary to put in twenty-two 

 pipes in each house, or nearly that num- 

 ber, for we around Chicago never use 

 more than eighteen pipes to the same 

 space, and some use only fifteen and have 

 no trouble in keeping warm. 



I should suggest that D. G. G. put 

 three pipes under each bench, if he in- 

 tends to build six benches to the house, 

 and the best and cheapest way to install 

 them would be as follows, assuming, of 

 course, that the houses run east and 

 west: Run the main, 4-inch in the first 

 house and 3-inch in the second, across the 

 two houses at the center walk, with a tee 

 at the center of each of the three north 

 benches, opening at the top. From 

 these branch with a li/^-inch pipe to the 

 bench on each side, down to just below 

 the bottom of the crosspiece under the 

 bench. Then run each 1%-iiich pipe to 

 the farther end of the house, run along 

 the end of the house and return under 

 the three south benches to the center, 

 connecting there with the return pipe, 

 which would only need to be 2-inch, with 

 a fall of one inch to twenty-five f«et. 



This system will give perfect satisfac- 

 tion, and as the pipes under the farthest 

 north bench return under the farthest 

 south, there will be plenty of pipe at the 

 ends to keep them warm. Allow not less 

 than two inches of space between the 

 cross pipes at the ends, for expansion. 

 One-inch valves at the flow pipes and %- 

 inch valves at the return would be large 

 enough. W. J. K. 



THE WATER "BLOWS OFF.** 



I recently installed a new hot water 

 boiler, rated at 6,400 feet of 2-inch pipe, 

 and have had trouble ever since. There 

 are two 4-inch perpendicular pipes run- 

 ning up from the second and third open- 

 ings in (he boiler. These connect into 

 3-inch pipes, which connect with the 3- 

 inch flow pipes running to the farther 

 end of the two houses, and there enter- 

 ing manifolds that supply the return 

 pipes under the benches — ten 2-inch re- 

 turns in one house and eleven in the 

 other. These returns connect with a 

 3-inch pipe at the bt iler end of the house, 

 and the 3-inch pipe connects with a 

 4 inch return which enters the boiler. 

 Altogether, there are twenty-one 2-inch 

 returns fed by the two 3-inch flows. The 

 drop in the 3-inch flows, from where they 

 enter the houses to the farther end, is 

 about thirty inches. The 2-inch returns 

 have a gradual drop to the boiler end of 

 the houses, and the 3-inch pipe which 

 they there enter has a straight drop of 

 two feet and then connects with the 

 4-inch, which has a gradual drop to the 

 boiler. The flow pipes have separate 

 connections to the boiler, one on each 

 side of the boiler. 



The expansion tank is a 20-gallon 

 barrel, and connection is made to it from 

 one of the returns, about twenty feet 

 from where it enters the boiler. The ex- 

 pansion tank is about two feet higher 

 than the highest part of the system and
