HOT WATER COIL. 



Would you kindly tell me how large a 

 coil I will need to heat from 1,800 to 

 •JjOOO lineal feet of 2-inch pipe? vWhat 

 size of pipe, and how many lineal feet 

 (»f it. will be required to make such a 

 ooil? A. B.C. 



1 take it from what you say that you 

 desire to construct a hot water heater out 

 of pipe and make it capable of heating 

 2,000 lineal feet of 2-inch pipe. If such 

 a coil were to be constructed from 2-inch 

 pipe it should contain 250 lineal feet of 

 2-inch pipe. If built from 1%-inch pipe, 

 320 lineal feet of pipe will be needed in 

 its construction. L. C. C. 



PAINTING STEAM PIPES. 



We notice in a recent issue of the Ke- 

 viEW an article on painting steam pipes, 

 and would like to ask your advice in this 

 connection. About a week ago, during 

 the absence of the superintendent, one of 

 our men gave the steam pipes in some of 

 our rose houses a coat of paint made of 

 white lead and oil. Do you think that 

 this will prove injurious to the plants? 



C. F. 



There is no danger to roses from the 

 fumes arising from white lead and oil. 

 The oil, however, gives off a disagreeable 

 smell when heated, and the white lead 

 will prevent proper radiation. If the coat 

 of paint is not heavy, there may be little 

 difference in the radiation, but all paints 

 with a heavy body, when used on steam 

 pipes, retard the dispersion of heat.

PIPING IN NEV MEXICO. 



We are sending you under separate 

 /•over plans of our heating system, which 

 is not satisfactory, and wish you would 

 give us some directions as to its improve- 

 ment. We have the Wilks No. 30 hot 

 water boiler. The expansion tank, which 

 has a capacity of ten gallons, is two feet 

 above the highest point of the flow pipe 

 and eight feet above the boiler. 



The fault we find with the system is 

 the slow circulation of water in the pipes, 

 as it takes two hours or more to get the 

 heat returned to the boiler. We are using 

 hard coal and, as it costs from $16 to 

 $23 per ton, we do not like to waste much 

 <^f it if we can be informed how to get

a better circulation. Would it be an im- 

 provement if the pipe of the expansion 

 tank were connected to the main return 

 near the boiler? F. 0. S. 



Your houses have almost the exact ra- 

 diation for a temperature of from 60 to 

 65 degi'ees in New Mexican climate, pro- 

 viding the plan sent is drawn to the ordi- 

 nary architectural scale of one-quarter 

 inch to the foot. The chief criticism I 

 would make of the system is in regard to 

 the location of the boiler and the manner 

 of carrying the flow pipes. If possible I 

 should cut out the loop in the riser in the 

 house adjacent to the boiler-room. Run 

 the riser direct from the boiler to the 

 main riser through this house; cut out 

 the expansion tank at this point. This 

 will make the distance traveled by the 

 water about twenty-five feet less in this 

 house. The 88-foot house, which stands 

 at right angles to the smaller one, I 

 should handle as follows: Use all pipes 

 now in the house as returns and carry the 

 main riser from the point where it enters 

 the house to a point under the ridge;
