Where There Is Coodeflsation 



— there is need for a Morehead Steam Trap. Condensation in 

 steam lines is akin to matter out of place — means wasted energy. 

 If your lines are sluggish — if your houses are not of uniform 

 temperature, write us. We guarantee to drain your lines per- 

 fectly — return the pure, hot condensation to your boiler without 

 pump or injector or make no charge for the trial. Obey that 

 impulse — write now.

will always 

 be main- 

 tained in 

 your steam pipes, no matter 

 now the preesure at the boiler 

 fluctuates, if you equip your 

 main lines with these valyes. 

 Oarry 40 or 50 pounds pressure 

 on the boiler, set the 



Hughson 

 Regulating Valve 



to carry 5 or 10 pounds on the 

 line and you will always have a 

 reserve in case of a sudden drop 

 in temperature. This valves 

 saves both fuel and worry. Ask 

 for catalogue and particulars.

PIPING IN NORTHERN OHIO. 



I should like to ask a question on hot 

 water heatinj;. How many 1^-inch 

 pipes will be needed in a house 20x100, 

 with a shed at the «ast end and a show 

 house at the west front? Will two 

 2-inch mains be sufficient to supply the 

 rest of the pipes? Which system would 

 give the better results, with the boiler 

 set in a "pit or on the level ground? 

 What size of pipe would you recom- 

 mend, 1-inch or 1^-inch? I could use 

 either size. K. H. 



For a house of the size mentioned it 

 will be best to tise an open tank sys- 

 tem, with the heater in a cellar or pit. 

 Use 21/^-inch pipe for thie flows and 

 2-inch for the returns. Of the former, 

 three will be required, one of which 

 can be upon each wall plate and the 

 other under the ridge. For the returns, 

 use three coils of three pipes each,

If a mercury generator, or any of the 

 other closed systems, is used, it would 

 be possible to heaf the house h) 60 de- 

 grees by means of three 2-inch flow 

 pipes and twelve 1^-inch returns, but 

 this system would not be as econom- 

 ical of fuel and would be less reliable 

 than the open system already described. 

 There would, of course, be considerable 

 saving in the cost of installation and 

 if other arrangements cannot be read-
