Just What You Want to Keep the 



Coal Bills Down 



When your boilers have become incrusted with scale you have treated them with 

 one of the many scale removers and found temporary relief. Next time try 



SCAi 



A 



Scaline will clean your boilers and KEEP THEM CLEAN. Fed into the boiler, it works its way 

 through the scale until it reaches the hot metal. Then it spreads along the metal surface and, expanding, 

 forces the scale to give way. In place of the heat-resisting scale there is now a thin HEAT-CONDUCT- 

 ING FILM which prevents further scale from forming and gives the boiler protection against corrosion 

 and galvanic action. One-fiftieth of an inch of scale within your boiler means the waste of a hundred 

 pounds of coal in every ton burned. Can you afford that? 



Order a barrel of Scaline today. Money back if not satisfied.

will make your smoke stacks, water tanks, pipes, 

 etc., proof against corrosion, acid and gas fumes.

Where is the proper location for the 

 flow and return pipes in all houses, also 

 what is the best way to carry the flow 

 and return pipes across to the separate 

 house? I desire a temperature of 50 

 to 65 degrees in zero weather. 



J. K. H.— Pa. 



As nearly as we can determine from 

 the data given, it will require about 

 2,000 square feet of radiation to heat 

 the houses as described. To make al- 

 lowance for the surface of the mains 

 and connecting pipes, and especially 

 since boilers are usually rated at their 

 capacity when hard coal is to be burned, 

 we should select one with a rating of 

 2,500 to 2,800 square feet, according to 

 the coal to be used. 



In the larger houses we should use 

 three 2%-inch flow pipes, and three 

 2-inch flows in the smallest house, 

 placing one flow on or near each side 

 wall plate and the other two feet below 

 the ridge. For returns we should use 

 ten 2-inch pipes in the 20-foot house, 

 nine in the 16-foot house and eight in 

 the 15-foot house. There should be a 

 coil on each side wall or under the side 

 benches of each house and another 

 under the middle bench. The wide 

 house should have four returns in the 

 outer coil and three in each of the 

 others. In the 16-foot house they 

 should be similarly arranged, except 

 that there should be only two pipes in 

 the middle coil. The 15-foot house 

 should have three pipes in each wall 

 coil and two in the middle coil. The 

 flow to the separate house can be carried 

 in the shed, or, if the top of the boiler is 

 three feet below the surface, it may be 

 run underground through a sewer pipe.

We have been told by a man who has

 life that his most successfully heated 

 houses have been by the following sys-
