carrying the 2*4 -inch flow direct from 

 the boiler through the large house and 

 the 2-inch flow from the other opening in 

 the boiler direct to the smaller house, 

 I think the results will be more satis- 

 factory than to attempt to heat both 

 systems from a single flow. If one flow 

 were to be used it should be 3-inch at 

 least. L. C. C. 



DEFECT NOT APPARENT. 



My boiler is a No. 4 Kroeschell, thir- 

 tj'^-six inches wide, thirty-four inches 

 high, nine feet long; the grate is thirty- 

 six inches long and the boiler has four- 

 teen 3Vj-inch flues seven feet long. The 

 house 1 am heating is 30x101 feet, five 

 feet to the plate, thirteen feet to the 

 ridge. T have the up-hill system, all 

 pipes under the benches. I use 4-inch 

 boiler flues. There are two flows out of 

 the boiler. They lead out one and one- 

 half feet above the top of the boiler. 

 The front flow goes across the house, ris- 

 ing two inches to the other side, and 

 eight inches to the farther end of the 

 house. The returns come back about 

 four inches below the flows. To every 

 flow there .-ire two returns, with the ex- 

 ception of one flow and one return I 

 put in later. I have fourteen strings 

 in the house, five flows and nine re- 

 turns. It is hard to keep it up to .50 

 degrees at night when 10 degrees below 

 zero outside. What is the defect? 



C. H. T. 



I can not detect any defect, either in 

 the installation of the pipe or the 

 amount supplied. In fact, the house 

 should be heated with fewer pipes. If 

 the water can be heated to 180 degrees 

 and the circulation is good there should 

 be no diflSculty in carrying this load. 

 You have only about 1,500 square feet 

 of radiation and the No. 4 Kroeschell 

 is rated to carry 3,500 lineal feet of 4- 

 inch pipe, or about 4,100 square feet 

 of radiation. L. C. C. 



CARE OF APPARATUS. 



Should the water be removed from a 

 hot water boiler during the summer? 

 Should hot water pipes be emptied alsof 

 If they are not emptied, what is the 

 damage done? Should a small fire be 

 started when the pipes and boiler are 

 empty to dry out the boiler? What 

 causes the pipes to sweat in summer? 

 Should the pipes be painted to preserve 

 them? How long does it take hot water 

 pipes to rust through? Should a Fur- 

 man steam boiler be emptied in summer? 



H. & C. 



At the close of the season, and sev- 

 eral 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 w;iter 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 sur- 

 rounding air, which causes the moisture 

 of the atmosphere to condense upon their 

 .surface. 



Although some growers paint the 

 pipes to preserve them, I believe it is 

 false economy, and pipes should never 

 be painted. A rusty pipe is a more 

 oflficient radiator than a painted pipe. 

 In other words, more heat can be re- 

 covered from a given amount of coal 

 with rusty pipes than with painted ones. 

 You lose in fuel more than you save in 

 pipes that are painted. L. C. C.

A NEW ESTABLISHMENT. 



I am a beginner and have just ar- 

 ranged to erect two houses and ask you 

 to help me in regard to heating them. 

 The two houses are connected, of wood 

 construction, each 20x75, eleven feet to 

 the ridge, and aide walls five feet. One 

 wall has two feet of glass, the houses 

 running ea.st and west, with the boiler 

 shed butted against the east end of the 

 houses. The west ends are glass. These 

 houses are for growing a general line of 

 greenhou.se plants, to be heated with hot 

 water. What size boiler will I need? 

 How will I place it and how will I pipe 

 the houses to a temperature of about 60 



Boilers made of the best material; shell, flre-boz 

 sheets and heads of steel; water space all around, 

 front, sides and back. Write for Information.

Since you have asked for suggestions 

 in addition to the question regarding the- 

 heating of your houses my flrs^t is, if not 

 too late, that you change the direction 

 of your houses from east and west to 

 north and south and that you place your 

 boiler pit and potting shed at the nortb 

 end of the houses. North and south- 

 houses get more sun during winter than 

 cast and west houses when buijt even-
