PIPING IN WYOMING. 



I am satisfied that I could build a 

 greenhouse by following instructions I 

 find in back numbers of the Review. 1 

 followed your instructions in the one I 

 built, 16x100, and it is a success. Now 

 I want to build one for bedding plants 

 and carnations. It will be 23x100, with 

 a three-quarter span to the south. It will 

 be built against a sloping hill on the 

 north side, and will be nicely protected. 

 Will one flow pipe feed eleven 2-inch re- 

 turns? Should I put the returns under 

 the beds or on the side? Will eleven 

 returns be enough? The flow will come 

 from a different opening in the boiler 

 than the one that feeds my vegetable 

 house. Should I put the flow pipe under- 

 ground or overhead? I use hot water 

 heat. May I not have the highest point 

 in the system at the boiler, using an over- 

 head flow, the downhill system and one 

 expansion tank for both houses? The 

 boiler is between the houses. The re- 

 quired temperature is 53 to 55 degrees. 

 The outside temperature sometimes falls 

 to 25 degrees below zero. 



What length should the rafters be on 

 each side for a three-quarter span, and 

 what would be the right pitch? 



E. W. O. 



While it would be possible to supply 

 eleven 2-inch returns by means of one 

 3-inch flow pipe, it will be better to put 

 in three 2'/^ -inch flows, one of which can 

 be upon each wall near the plate, and 

 the other either under the purlin or two 

 feet below the ridge. Under the severe 

 <'onditioiis mentioned, it will be safer to 

 use twelve 2-inch return pipes, instead 

 of eleven, as suggested. If the sashbars 

 on the south side are fifteen feet and 

 those on the north side of the house are 

 ten feet, it will give about the right 

 pitch. 



The best results can be obtained when 

 the downhill system of piping is used, 

 and one expansion tank will answer for

both houses, provided it is connected at 

 the highest point and the piping is such 

 as to permit the air to escape from the 

 system through the pipe which leads to 

 the expansion tank. 



WRONG SYSTEM OF RETURNS. 



I am taking charge of a range of new 

 houses in southwestern Pennsylvania, and 

 we expect to add to the range in the 

 spring. As the heating system, which 

 was installed by a local plumber, is un- 

 satisfactory, I should like to get your 

 opinion. There are two houses, 23x100, 

 running east and west, with a hot water 

 boiler in a deep pit. A 4-inch pipe rises 

 to the highest point, over the boiler, and 

 from there extends to the far end, where 

 it branches to two 3-inch returns, one 

 under each side bench, running back to 

 the boiler. There are six cast-iron wall 

 radiators, 2^^x11 feet, rising at inter- 

 vals from this 3-inch return on each side. 

 The return, being a continuous flow, gets 

 hot, but it requires from three to four 

 hours to heat up the radiators. The 

 boiler is a 5-section Ideal, and the fire- 

 box is 3x31/4 feet. J. W. O. 



The description given of the piping is 

 not sufficiently definite to show just what 

 the trouble is or to indicate the heating 

 surface of the radiators. While it would 

 not ordinarily be considered an ideal way 

 to heat the houses, there is no reason why

the water should not circulate in the 

 radiators, provided the connecting pipes 

 are properly put in and they are high 

 enough above the boiler to provide for 

 a free circulation. I infer that the radi- 

 ators are but little above the level of the 

 3-inch return pipes, and if these returns 

 have direct connection with the boiler it 

 is not strange that the circulation in the 

 radiators is slow. The correct way to 

 arrange the piping would be to connect 

 each of the radiators with the 3-inch 

 main, using a 2-inch pipe if they furnish 

 more than 150 square feet of radiating 

 surface. There should be no direct con- 

 nection of these main returns with the 

 boiler, but there should be another return 

 pipe on each side of the house to connect
