be free, as far as possible, of the ob- 

 jectionable features. 



As may be learned from any steam 

 table in a text book, water will boil 

 or vaporize at 212 degrees at the sea 

 level and at atmospheric pressure, and 

 at 98 degrees in a perfect vacuum. It 

 follows that if confined in a vacuum 

 of any degree between these two 

 points, water will boil, or vaporize at 

 a corresponding temperature. 



In the simple or ordinary vacuum 

 heating systems, the steam after con- 

 densing in an ordinary radiator or coil 

 is discharged as water from that coil 

 through a vacuum valve that is sup- 

 posed to only allow the water of con- 

 densation and the air to escape. This 

 discharge is into a partial vacuum, as 

 the entire return system is under this 

 partial vacuum and is produced by a 

 vacuum pump at the end of a return 

 line. 



As, even when heating under steam 

 at atmospheric pressure, this water of 

 condensation has 208 to 210 degrees 

 when discharged through this vacuum 

 valve into the partial vacuum, and as 

 water at 2U2 degrees will vaporize un- 

 der a vacuum of five inches (or 2 1-2 

 inches negative pressure), it follows 

 that this water still has heat enough 

 to allow at least a part of it to vapor- 

 ize when traveling along these return 

 pipes toward the vacuum pump; as a 

 result, a jet of cold water is injected 

 into this return pipe just before it 

 teaches the pump in order to con- 

 dense this re-evaporation and so al- 

 low the pump to handle it. 



Now, in condensing 1 this vapor the 

 units of heat in it have to be destroyed 

 by the jet of cold water, and all the 

 benefit derived from such loss of heat 

 is in allowing the pump to continue 

 the vacuum by handling this vapor; 

 advantages of the vacuum system are 

 enough to warrant this extravagance, 

 and with a vacuum system, it has al- 

 ways been considered absolutely nec- 

 essary to indulge in such. 



To secure a further economy in util- 

 izing the units of heat in radiating 

 surface, that are destroyed by the jet 

 of water in the simple system, by con- 

 ducting the water of the condensation 

 through a secondary coil, or radiator, 

 that contains the same partial vacuum 

 as the return system we can utilize the 

 heat of this vapor in giving out heat 

 to this secondary coil; this coil acting 

 as a surface condenser in doing the 

 same work as the cold water under the 

 other plan. After this re-evaporation 

 is again condensed, it passes to the 

 vacuum pump as solid water. 



With such a system it is not neces- 

 sary to carry any steam pressure on 

 heating system, as when the weather 

 is moderate, steam at one-half pound 

 to one pound below atmosphere can be 

 carried, or even lower, and a perfect 

 circulation secured at a corresponding- 

 ly lower heat. The vacuum pump al- 

 ways removes the air and water at any 

 reasonable pressure below atmosphere 

 it is desired to operate it under, so 

 that every square inch of radiating 

 surface is heated surface. The steam 

 mains can be considerably smaller 

 than for gravity steam, or for hot 

 water. The returns are very much 

 smaller than with either steam or 

 water systems. 



It is not necessary to carry return 

 pipes back under ground, as they can, 

 as well, be carried overhead. No air 

 valves are needed.
