u. -). A-eaiL5aAn5 ,aiA oa C u a Baker Williams on Shabona Lane in Indian Hill Estates, Winmette, tbrough *the use of a new type of gas-fired air heating plant. The new, system appears to be as. much in -advance of the even recently. new hotwater oil heat as that was *over furnace heat and as furnace heat was over stoves., We may expect rad- .ca1 evision in the design of oil bot-. water. systems if they are to meet this new coômpetition. For some* years, the forward look- ing housewife has been asking of the: engineer,and builder not only fresh warmairin irculationi in the winter -not the:dead desert.,air of the bot water or steam radiator - but'also cool, moving breezy air in ber bouse in 'the summertime., She says-and rig htly-"you. gave me mechanical re- frigeration, the 'vacùuum cleaner, gas for cooking-now give me this." And she gets wbat she wants. The fuel ed in the new beaters *is gas-witb uie '-mazinig efficiency of 94.6 percent claimed by the makers. Only suficient heat remains in the flue gases to assure a draft that will supply, the air reqiiired for combus- *tion., Indeed the outgoing burned *gases are so cool you can hold your band and cheek against the flue- pipe while the furnace is in fuit blast., At the saine time the air duct to the rooms is too bot to hold the band on with comfort. Itumidity la SuppiseI Humidity of tbe air - that great requisite to comfort and bealth-is supplied by a simple and econornical *metbod. Water for the air is taken f rom the gas-niot before but after *it is burned. Hydrogen in the gas-- if ,you will recall your first lessons in chenistry-unites witb oxygen in the 'air in burning and yields H20- wbich is water. That water vapor is condeused and run througb a lime- stone filter to take out impurities and then so much of it as desired is put into the air to the rooms. So any. degréee of bumidity desired can be maintained. Another controllifig feature of at-, niosphere -comfort.is air in controlled New, Systeu Hat Futuare: Another defin ite opportunity for the new systemn lies in the many old homes with "furnace heat" on the north shore.

Sucb an installation will not be 100 percent efficient but better'. than. any other system that supplies heat only -without -moisture and wit-hout cir- culation. Installation cs of the new type of hecater -iii Estates ,wâs found, to be some what low'er than a w4l designed oil hotwater system- and cost of gas because of the high. efficiency is, said, to be about the. saine, as oul for burn- ers using the lighter grades. Ce rtain it is tha t improved methods. of home heating are near at hand for several 'manufactur.ers are, after pe- riQds of rescarcli. and experimenta-, tion, ready to put on the market gas- using beating units of very high efficiency producing moving air of controlled humidity. .The developers of Indian Hill Es- tates had the foresight four years ago to instail gas pipes in that community of sufficient capacity at considerable additional cost so that every house there can be heated with gas as soon as the combination of mechanical and technical achievement and rates for gas make it possible.
