turn pipes, with one extra return in the 

 coil on the east side of the house, having 

 glass in the side wall. 



Eun the flow pipes downhill, and con- 

 nect the highest point in each flow pipe 

 with the expansion tank, which should 

 be at least two feet higher. 



BOILER'S CAPACITY. 



I have a Kroeschell boiler. It has a 

 fire box thirty inches wide and forty- 

 eight inches long. It has fourteen 3- 

 inch flues and is tapped for two 4-inch 

 flows and returns. It has a 14-inch 

 smoke pipe. What is the capacity of 

 this boiler and how large an area of 

 glass will it heat when the outside tem- 

 perature is 10 degrees below zerot I 

 have one house, 20x50, but intend to 

 build another one, 25x75 feet. 



G. W. L.— Pa. 



A Kroeschell boiler of the size de- 

 scribed will easily supply from fifty to 

 100 per cent more radiation than the 

 two houses will require, according to 

 the kind of coal used and the skill of 

 the fireman. 



To heat the new house, it would be 

 advisable to use three 2% -inch flow 

 pipes, placing one on each side-wall 

 plate and the other two feet below the 

 ridge. For the returns use either eleven 

 2-inch or thirteen 1%-inch pipes, with 

 four of the former and five of the latter 

 on the walls or under the side benches, 

 and the other three under the middle 

 benches. 



If the flow pipes run downhill and 

 the expansion tank is connected with 

 the highest point in the main 4-inch 

 supply pipe leading to this house, no 

 air valves will be required. 



SYSTEM FOB SMALL HOUSE. 



I am building a small greenhouse, lOx 

 25. It will have three feet of concrete 

 wall, with two feet of glass above the 

 eaves. Is there a small heating system 

 on the market suitable for such a 

 house; one that will give a winter tem- 

 perature suitable for pot plants and 

 flowers for cutting? I know one man 

 who used an ordinary hard coal heater 

 for such a liouse, but I do not know 

 just what results he secured. Is the 

 Areola all right? L. C. E.— O. 



To heat the above-described house to 

 60 degrees in zero weather, about 160 

 square feet of radiation will be re- 

 quired, but it would be advisable to 

 use a hot water boiler rated at about 

 250 scjuare feet of radiation. Nearly 

 all of the manufacturers of hot water 

 boilers have them of about this size. 

 The Areola, manufactured by the Amer- 

 ican Eadiator Co., is an excellent boiler 

 for small houses. 



To heat the house, it would be advis- 

 able to run one 2%-inch flow pipe under 

 the ridge to the farther end of the

PIPE and FLUES 



A LL SIZES of second-hand pipe, with 

 ■** new threads and couplings, in ran- 

 dom lengths or cut lengths. Also 

 make a specialty of handling boiler 

 flues for retubing boilers or for green- 

 bouse piping. All flues are trimmed 

 and thoroughly cleaned by machine.
