It was not heating until after World War II that transcontinental pipelines brought natural gas to nearly all parts of the United States, but since then upward of 35 million heating gas burners have been installed for home heating systems—twice the number that have oil heating burners. As a fuel, gas is more expensive than oil in many areas. But a gas heating burner is less costly to install than an oil burner: gas heat pollutes less than oil heat: and gas delivery does not depend on a truck’s ability to brave a blizzard. Most heating gas burners consume natural gas mixed with air in the ratio of about 1 cubic foot of gas to 16 cubic feet of air. The efficiency of the burner depends on the mixture, which a heating serviceman should adjust. Most other heating problems involve the pilot and its thermocouple safety device; this heating or furnace repair problems can generally be corrected by the homeowner.
How a gas heating works
When the contacts of a house heating thermostat close (page 300), current runs to a solenoid, opening up a diagram heating valve in a combination control. Gas flows (small arrows) from a supply line past a manual shutoff, through a heating manifold, then to tubes that mix it with air (broad arrows). The mixture goes to heating burners where ignited by a pilot. It makes heat that a heat exchanger turns to steam. Hot water or warm air; wastes go up a flue. The heating thermocouple and another solenoid stop gas flow if the pilot goes out.
Adjusting the heating pilot flame
A heating thermocouple (left and opposite, top shuts off gas if the pilot light goes out. But the pilot will not stay lighted if it is too low to heat the thermocouple. In many heating unit models the pilot flame may be raised or lowered by taking off the screw cap and carefully turning the adjustment screw on the combination control to regulate flow in the pilot supply line. Pilot reigniting procedures also varies they are on a metal tag attached to, or near. A-gas cock on the combination control. Over half the central heating systems in American houses are the forced-warm-air type-29 million units. Unlike hot-water and steam heating systems, a forced-air heating system uses no water, so there is no danger of burst pipes, no need for filling or draining. It warms and circulates air with a heating burner, a motor-driven fan—or blower—and a duct network.
Because it distributes warm air under draft, a forced-air heating system is more efficient than one that depends on the principle that warm air rises: it can send heat where needed and keep temperatures steady. So it provides comfort at lower furnace temperatures than its predecessor and burns less fuel. The heating unit or furnace may use oil or gas, a heating pump or an electric resistance coil. Most forced-warm-air heating systems humidify, or can be modified to do so and generally can be adapted to cool the house in summer. Cooling may be achieved simply by opening a panel to circulate basement air throughout the house or, more elaborately, by utilizing the ducts and blower in conjunction with a central air conditioner. Despite its versatility, the forced-warm-air heating system is so simple in construction and operation that the owner can deal with most of the problems that may occur.
How heating air circulates
The heating furnace, containing both the burner and the blower, is topped by a chamber called the warm-air plenum. This leads to a long main supply duct that feeds into branch ducts, which in turn supply openings called warm-air registers that release heated air into each room.
Dampers inside the main and branch ducts can be adjusted by lever handles to balance the flow, so that each register receives the desired quantity of warm air (page 312). Each register also has a damper to regulate air flow. Warm air flows upward from these registers (wavy arrows). Cooler, heavier air drops to the floor and flows through return air grilles to a return air duct leading back to the furnace. A small two-story house usually has one return grille per story. Larger homes may have return grilles in each room.
How a forced-air heating furnace works
Heating furnace, designed for a gas or an oil burner (not shown), circulating air enters at the bottom, where a filter traps dirt. The blower forces the air up into a compartment called a heating exchanger, which contains metal passageways heated to temperatures of several hundred degrees by combustion gases rising inside. The passageway exteriors heating the circulating air as the blower forces it past and on into the warm-air plenum of the network of ducts. A fan-and-limit control switches the heating blower off and on, and turns off the burner if circulating-air temperature rises too high. The combustion gases, which do not mix with circulating air, escape through a stack to the chimney. A forced-air heating system that included a heat pump would contain a second heat exchanger in the return air duct. The humidifier, which moisturizes dry air, also enhances the heating systems efficiency because people feel more comfortable at lower temperatures in moist air than in dry air. It operates on the same principle.
