Heating a Modern Eight-Room Dwelling P. W. Rathbun in the National Builder discusses the PressureSystem of Hot Water, and the Economy of such an Installa-tion. The accompanying plans show a con-venient eight-room dwelling Avhich wasrecently erected at a cost of $2,000. Itis of frame construction with cementblock cellar walls and concrete floor inthe excavated part of the basement. Theprice given above does not include heat-ing or plumbing. The heating will betaken up in this article. Hot water heating has for many yearsbeen a problem on which numerous ex-perts have worked to bring about effici-ency and the construction of a first-classapparatus at a reasonable price. A fewyears ago there were several pressure. E Piping Plan in Basement. apparatus put on the market to revolu-tionize hot water heating. Practically the entire public and pros-pective builders have been misled bytheoretical writers^ whose theories madea hot water heating system cost the partyinstalling it a vast sum of money, morethan was absolutely necessary, and whichpractically goes to the pipe manufac-turer for large piping and to the wastingof an endless amount of physical exer-tion in cutting, threading and assemblingsame, to overcome friction. By practi-cal experiments and experience, the writ-er found that with pressure heating ateleven (11) pounds applied to the waterin the system, either by the use of regu-lating valves or mercury appliances, thepipe areas can be safely reduced 50 per 12 cent, and the radiation 15 per cent., withtappings from 60 per cent, to 80 percent, smaller than are used with the oldopen tank system.
