In case of emergency, steam at any 

 pressure up to twenty-five pounds 

 (2G5 deg.) can be used and can be se- 

 cured on a moment's notice, as the 

 boiler pressure will be about that all 

 of the time, and the pressure needed 

 in system, regulated by a reducing 

 valve as required; usually less than 

 one pound pressure (212 deg.). The 

 temperature of secondary coil is from 

 170 deg. to 195 deg., according to 

 vacuum carried. 



Such a system allows of controlling 

 the heat in any or all coils, as desired, 

 as it is not necessary to have the en- 

 tire coil either entirely free of steam 

 or completely full as, the vacuum 

 pump keeping the coils free of air and 

 water, the steam valve can be opened 

 to admit only sufficient steam to heat 

 as much or little of the coil as desired, 

 and this will continue as long as these 

 conditions exist. 



An automatic heat regulator will 

 give much closer and more economical 

 results than can be possible by hand 

 regulation. Also, being on guard all 

 of the time, such an apparatus is al- 

 ways ready to take care ot any condi- 

 tions that may come up, and owing to 

 the quick change secured by the steam 

 in the radiating surfaces, an approxi- 

 mately uniform temperature is se- 

 cured, according to the temperature 

 the thermostat is set at, in the room. 



The sun may break through the 

 clouds fifty times a day and give suffi- 

 cient heat for a few minutes' time that 

 would result in overheat if the artifi- 

 cial heat was used at the same time, 

 with an automatic regulation. How- 

 ever, this heat is shut off before any 

 overheating takes place, and remains 

 off as long as the temperature is main- 

 tained by this outside source. 



To better illustrate the economy in 

 automatic heat regulation, it Is only 

 necessary to consider that as ordinari- 

 ly figures, the radiation in any build- 

 ing is considered ample to heat that 

 building to a certain temperature when 

 the outside temperature is zero, or 

 even ten degrees below zero. And 

 while in reality such conditions do not 

 exist very many days and ofttimes the 

 outside temperature is very moderate 

 for days, during which time the entire 

 radiation is not needed, it follows that 

 all of the time any part of it is shut 

 off, the demand on the boiler is re- 

 duced that much, and a corresponding 

 decrease in coal should result. 



The thermostat acts as a very re- 

 liable servant, who keeps close watch 

 of the thermometer, and when the prop- 

 er temperature is secured, immediately 

 closes the steam valves on the coils, 

 allowing them to remain closed until 

 the thermometer shows the temper- 

 ature to be dropping, when these 

 valves are opened again. With these 

 vacuum systems the boiler can be set 

 on the ground level, or even above, if 

 desired. Everything can be made 

 automatic, as both pumps and dampers 

 can be controlled mechanically, to 

 conform to the conditions giving the 

 best results.
