SIZE OF STEAM LINE. 



What size steam line will it take to 

 supply three houses each 18x200 for car- 

 nations and one house 21x200 for roses 

 and what size opening will it take in the 

 boiler to supply the size line that is re- 

 quired? The houses are five feet to the 

 gutter and ten feet to the ridge. T. J. 



To supply the four houses in question 

 with steam, the main supply pipe should 

 be a 6-inch. If the boilers are provided 

 with 4-inch openings and are worked in a 

 battery of two or three, better satisfac- 

 tion will be secured than from using one 

 large boiler. The boilers can be yoked 

 together by a cross line of 6-inch pipe 

 fed from the boilers through 4-inch. 



PIPING IN KENTUCKY. 



I wish to know how many runs of 2- 

 inch pipe it will take under each bench to 

 heat a house 43x54 feet. I use hot water, 

 and wish to heat to 50 degrees. Some- 

 times we have zero weather or lower 

 for a few days. I wish to grow carna- 

 tions and bedding plants. The house will 

 have six raised benches and one bed six 

 feet wide, with 2-foot walks between. 

 Will one 2-inch flow and two 2-inch re- 

 turns under each bench be sufficient! I 

 have at present in my house 15x40 feet 

 two 2-inch flows and three 2-inch returns, 

 or about 500 feet, which is satisfactory. 

 In the house 10x45 feet I have about 600 

 feet of 1%-inch pipe. What size boiler 

 should I have to heat the whole plant? 

 Mine is rated for 1,700 square feet of 

 radiation. Is it necessary to lower the 

 boiler, which is at the lowest corner, on 

 account of the slope of the ground, and 

 if so, how much? K. Y. 



The quantity of pipe you have esti- 

 mated, viz., one 2-inch flow and two 2- 

 inch returns under each of the seven 

 benches of the house 43x45 feet, should 

 be sufficient to maintain the temperature 

 specified. As the three houses require in 

 the aggregate about 1,000 square feet of 

 radiation, a boiler rated to carry 1,500 

 square feet of radiation would be suffi- 

 cient for your work. 



CAHE OF APPARATUS. 



Should the water be removed from a 

 hot water boiler during the summer? 

 Should hot water pipes be emptied also? 

 If they are not emptied, what is the 

 damage done? Should a small fire be 

 started when the pipes and boiler are 

 «mpty to dry out the boiler? What causes 

 the pipes to sweat in summer? Should 

 the pipes be painted to preserve them? 



M, C. 



At the close of the season, and several 

 times during each season, the boiler and 

 heating pipes in either a steam or hot 

 water heating plant should be drained 

 and washed as thoroughly as possible, 

 but never should be left empty. If after 

 draining, as above noted, the plant can 

 be filled with rain water, there will be 

 less deterioration than with the use of 

 well or spring water. Before starting 

 the fires in the fall, drain off the water 

 that has stood in the plant during the 

 summer, refill with fresh water and go 

 ahead, if all joints are in good repair. 



Never make a fire of any kind in an 

 empty boiler, whether it be a steam or a

hot water boiler, unless you wish to 

 ruin it. 



The so-called sweating of water pipes 

 is due to the fact that they have a lower 

 temperature than that of the surrounding 

 air, which causes the moisture of the 

 atmosphere to condense upon their sur- 

 face. 



Although some growers paint the pipes 

 to preserve them, we believe it is false 

 economy, and pipes should never be 

 painted. A rusty pipe is a more efficient
