How to Check for a Defective Heating Thermostat

If your room heat temperature drops 5° or more be-low the point at which you have set the thermo-stat and your heating system does not start, the first thing you should do is check the heating system. If you find nothing wrong with the heating system, test the heating thermostat.
Remove the heating thermostat cover and body from the wall, leaving in place only the wiring leading to the heating burner, and the back plate. Check the heating thermostat body and the back plate to make perfectly sure that there are no broken wires and that all of the wires are tightly secured under their terminal screws. If your heating system has an open-contact thermostat, clean the contacts at this time.
If you still have not located the source of your heating trouble, take a five-inch length of insulated wire and strip half an inch of heating insulation from each end of it. Holding only the insulated portion of the wire touch the bare ends to the heating terminals on the back plate. If the thermostat has a three-wire connection, carefully push the contacts closed with a block of wood. If the heating burner goes on, the heating thermostat is defective and must be replaced. But if the thermostat burner does not go on, the problem is elsewhere. Remount the heating thermostat and call your heating repair serviceman.
Heating warm-air systems offer the most possibilities for adjustment. The basic method is to position heating dampers inside the warm-air ducts to regulate heating air flow. Generally the heating damper con-trolling air flow to the most distant room is fully open, the one nearest the furnace almost closed. Adjust the heating air flow to all rooms by speeding up or slowing down the heating blower. On many heating units, this is done by adjusting the heating blower pulley to change the heating ratio between the motor drive and the blower. On other heating models, speed is regulated by moving a switch or by changing the blower's electrical connections. Lowering the heating temperature at which the heating blower turns on starts warm air circulating sooner and saves fuel by using all the furnace heat.
Improving the heating efficiency of any heating sys-tem is important in times of soaring fuel costs. Some of the most effective steps:
1. Insulate the attic. Six inches of heating insulation can cut fuel consumption up to 25 percent; Ten inches will work even better in cold regions.
2. Weather-strip doors and windows.
3. Add storm doors and windows; in cold areas they will pay for themselves in a few years.
4. When a fireplace is not in use, keep the heating damper closed; an open chimney wastes heat.
5. Put heavy draperies on doors and windows, and keep them closed at night and when rooms are not occupied.
6. Lower your heating thermostat gradually, a degree at a time, to accustom yourself to a lower heating temperature. You may actually find that you are more comfortable with less heat.
