There is on the market a covering for radiators which is very satisfactory. There is more heating surface in this type too. The water content is ¹⁄₂ the content of other radiators. This means quick and positive venting for steam, vapor, or hot water installations and provides rapid circulation, causes radiator to heat up more rapidly. AIR VENT (STEAM HEATING) The air vent on each main, allows the air to escape so that the heat arrives more rapidly to radiator. This of course, saves fuel. HEAT CONTROLS To take the heating of your home out of the area of dreams and out of the expensive realm of “feeling,” some sort of heat regulating device is recommended. It is foolish to say “Do you think it is warm enough?” to a group in the room. For no two will think alike! Apart from this, the perfect thermostat not only tells you at what temperature is your house, not only keeps the house evenly heated, but in doing this saves you fuel, expense, illness and what not. By simple mechanical means the thermostat opens and closes the door of the furnace as the heat needs to be lowered or increased. In this way if less heat is required, the door closes, and less coal is used etc. Thereby another simple yet ingenious device. The thermostat can be set to do these things at any _time_ you wish it to be done. If you want the damper opened at 7 A.M., so it will be done--and you don’t need to go in your pajamas boiler-ward! There are two or three excellent thermostats on the market and many not so good. Be sure you consult before investing. The best thermostats have no corroding, or wearing parts, look well and prove themselves thoroughbreds. The thermostat prevents cooling off of the boiler which means starting a fire over again--which means wasted fuel. All means must be taken against such waste. Much coal is lost in uneven combustion, some coal being entirely wasted. The thermostat prevents this, by ordering a steady, definite consumption of coal. It takes far less coal to heat hot or tempered return water than to heat cold--the thermostat prevents the cooling down entirely. THE BUNGALOW OWNER There is now on the market a hot water boiler which is compact and good-looking which if put into a cellarless house heats it with the efficiency of the subterranean boiler! This is done through pipes and radiators and with a maximum comfort and a minimum care. HEAT’S INFLUENCE It is usable in schools, cottages, etc., and bids well to civilize sections of the world which have starved for heat and consequently have been stunted in physical and mental growth. This boiler is the Ford of boilers, giving unto every man the right to be comfortable wherever he lives! HEATING WITH OIL Oil heaters for special rooms are made by the principal oilstove makers. These give good results but of course are not comparable to hot water heating, steam etc., plants. ELECTRIC HEATING
