is to run four 4-inch flows, two at each 

 gutter, and eighteen 2-inch returns. 

 Would it be more satisfactory to run 

 one flow at each gutter, and one at 

 each purlin? Is l^^-inch pipe as satis- 

 factory as 2-inch for returns? If so, 

 how many returns would I need? Does 

 painting the pipes reduce their heating 

 power? What size of boiler would I 

 need to heat the house to a temperature 

 of about 60 degrees in this Illinois 

 climate? W. B. W. 



If four 4-inch flows are used, thirteen 

 2-inch returns will be needed to main- 

 tain a temperature of 60 degrees in 

 the house described. However, it will 

 be found that four 2i^-inch flow 

 pipes will 8u£5ce to maintain the de- 

 sired temperature, with fifteen 2-inch 

 returns, and this arrangement is sug- 

 gested, placing two flows on the pur- 

 lins. In shorter houses 1^-inch returns 

 answer quite well, but when the houses 

 are over seventy-five feet long, it is 

 better to use 2-inch pipes for the re- 

 turns. A boiler with a rating of 1,500 

 square feet will be ample. If a paint 

 composed of lampblack and equal 

 parts of turpentine and linseed oil is 

 used, it will not impede the heating. 



HEAT FOR SERVICE BUILDING. 



We have a two-story frame ofiice and 

 service building that we want to heat 

 with a separate system from any other. 

 We recently purchased a heating outfit 

 that had been used for steam. We 

 have thirteen direct flow 16-foot wall 

 coils, 1-inch pipe, of eight pipes each, 

 manifold tapped 1-inch. We have 

 about 1,000 feet of 114-inch, 2-inch, 

 214-inch, 3-inch and 4-inch pipe to go 

 with it. Our building is 40x130 feet, 

 two-story frame, with building paper 

 for inside walls. The first floor has a 

 10-foot ceiling, the second floor an 

 8-foot ceiling. We want to heat with 

 hot water. Could we use the steam 

 piping by reversing the flow and return 

 pipes? We want to place the boiler at 

 about the center of the building on one 

 side. Could you tell us what size of 

 boiler we woiild need and also the size 

 and amount of pipe needed, providing 

 we could not use the pipe we have?
