Sreenhonse Heating. 



Subscribers are invited to write the 

 Editor of this Department with regard to 

 any details of greenhouse heating that 

 are not understood. But please do not 

 ask The Keview to make a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment advertised in this paper is, we 

 believe, the best for the trade to huj, 

 and each article the best in the special 

 field of its adaptation. 



IF THE TRAP NEEDS REPAIRING. 



Can you tell me what to do in case 

 the trap on my steam heating system 

 should happen to stop or be put out of 

 commission in auv way? 



T. B. S.— la. 



Just what can be done when a 

 steam trap fails to work, will depend 

 to some extent upon the construction 

 of the trap and the arrangement of the 

 heating system. It may be possible to 

 correct the difficulty so that the trap 

 will be at least fairly efficient. In 

 some traps there are valves which need 

 grinding, or stuffing boxes that require 

 packing, while in others some slight ad- 

 justment is all that is required. Some- 

 times increasing the steam pressure 

 will remove the trouble. In most cases 

 there should be a cheek A'alve upon the 

 drip pipes on both sides of the trap. 



If the water level of the boiler is at 

 least three feet below the returns, the 

 water will return by gravity if low 

 pressure is carried. Provided the trap 

 cannot be made to work, it can be taken 

 out and either an injector or a steam or 

 electric pump substituted, unless a new 

 trap is procured. 



FIRING CONNECTED BOILERS. 



I am heating my range with an 80- 

 horsepower tubular boiler, using gas as 

 fuel. In extremely cold weather, how- 

 ever, there is not a sufficient pressure 

 of gas to keep up the necessary steam. 

 Attached to this boiler by main steam 

 and return lines, and set so the two 

 can be fired together, is a smaller 2- 

 flue boiler, of twenty liorsepowcr. This 

 smaller boiler is not connected with the 

 gas mains. I fear that firing one l)oiler 

 with coal and tlie other with gas will 

 produce too uneven results for connect- 

 ed boilers. What would be the best 

 way to handle the small boiler, in using 

 it as an aid to the larger one? I am

W. C. K.— Pa. 



If the water level in the two boilers 

 is the same, we should not expect any 

 serious trouble if the pressure in the 

 large boiler does not exceed five pounds. 

 There sliould, of course, be check 

 valves in the return pipes near each of 

 the boilers. 



BETTER USE FOUR FLOWS. 



I intend to build another greenhouse, 

 28x125, with 6-foot side walls, con- 

 taining three feet of glass and three 

 feet of concrete. I have a cast-iron, 

 sectional, hot water boiler, with a grate 

 measurement of 28x32 inches. Will this 

 boiler be large enough to heat the house 

 to .'SO degrees in zero weather? I in- 

 tend to use three 214-inch flows, each 

 connected at the farther end witli four 

 2-inch returns. Would that system of 

 piping be amply sufficient to give the 

 desired temperature? E. F. C. — Pa. 



While the capacity of boilers varies 

 to a considerable extent with the effi- 

 ciency of the fire surface, if the boiler 

 in question is in any degree efifective

we would consider that it will handle 

 1,500 to 1,600 square feet of radiation. 

 As not over 1,200 feet will be needed 

 ill the house described, this should 

 leave a safe margin. 



The piping suggested affords all the 

 radiation required and is fairly well 

 balanced. While no more radiation is 

 required, the flows will be loaded to 

 their full capacity and we would pre- 

 fer to use four instead of three. We 

 would then expect better results with 

 ten returns than with twelve returns 

 and three flows. Valves should be 

 placed upon one or two pipes in each 

 coil, so that they can be cut out in 

 mild weather.
