I am concern of premature motor wear but does this save electrical cost as
perhaps causes the system not to turn on as much as the circulation of heat allows improved heat distribution.
could you give a percentage of cost savings if the fan is on constant?

LET'S START OVER. ON AN ELECTRIC FURNACE YOUR HEAT FOR YOUR HOUSE IS COMING FROM THE ELECTRIC HEATING ELEMENTS AND ALSO FROM THE HEAT GENERATED IN THE MOTOR DUE TO THE RESISTANCE IN THE WINDINGS. THE HEAT FROM ONE OR THE OTHER SOURCE COSTS THE SAME-PERIOD. THERE ARE TWO OPINIONS ABOUT RUNNING THE MOTOR ON "AUTO" OR "ON" POSITION. IT COMES DOWN TO THE OUTDOOR TEMPERATURE AND THE INSULATION OF THE HOUSE. DO WHAT IS MOST COMFORTABLE FOR YOU. THERE ARE SOME DIFFERENCES IN COST BECAUSE OF THE HEAT THAT MAY BE LOST IF YOU HAVE DUCT LEAKS OR THIN INSULATION ON THE ATTIC DUCTWORK AND YOU MAY HAVE SOME OTHER SLIGHT VARIABLES THAT I BELIEVE WILL NOT CAUSE YOU TO LOSE ANY MONEY DUE TO ELECTRICAL USAGE. IN SOME AREAS THE POWER COMPANY WILL DO A FREE HOME AUDIT TO SEE HOW YOU CAN REDUCE THE POWER USAGE. TAKE ADVANTAGE OF IT, IF THEY DO IT IN YOUR AREA. THE MOTOR WILL DRAW MORE CURRENT WHEN STARTING, BUT THAT WILL MAKE NO DIFFERENCE SINCE YOUR THERMOSTAT WILL SHUT OFF SOONER BECAUSE OF THE MOTOR HEAT. MOTORS USUALLY FAIL WHILE TRYING TO START AND IN MY OPINION THEY LAST LONGER IF LEFT RUNNING-ASSUMING THEY ARE LUBED PROPERLY. A GOOD MOTOR WILL LAST SEVERAL YEARS OR MORE IF PROPERLY SIZED.

No percentages here BUT the greatest draw on power is in the initial start of something whether it be a motor or it be a light bulb or a computer. If a fuse is gonna blow it would at this moment. Once heat has left the heater it moves upward and is out of the circulation path.

Having the fan run all the time is expensive in both operating and maintenance costs. You will get some advantage in the circulation of air, but generally it is not worth the cost.

Unless your heating system has a commutative DC drive blower motor, the electric bill will increase by about 15% with continuous blower operation, even though the heat strips will cycle normally to maintain your residence at a comfortable temperature.

I always have mine on auto, because of the power bill will be a lot higher if the fan runs all the time and I'm sure it would wear it out a lot faster get a maintenance plan like ever fall have it serviced.

It should not run all of the time...it also forces air out of windows,doors and cracks....set it on auto. If you need good circulation, get some ceiling fans, set them in reverse for down draft

it would cost more to leave it running than letting it stop and start
