Stratification and furnace blower
I have a new home equipped with 2 Weather King Furnaces, one for each level. The second level of the home is a loft type and open to the lower level via a 8x7 foot opening.
My question is given the effect of stratification, warm air rising while cool air sinks, would it be more efficient to have the unit blowers run continuously on one or both of the units in order to keep a uniform temperature throughout? It seems the lower floor unit runs much more then the loft area and I attributed this to the fact the heated air from the ground floor is infiltrating the lost area and minimizing the need for the upstairs unit to fire up. Am considering closing the opening to the Loft area but that is expensive and would like to explore other ideas first. I seem unable to find the power usage of the fan motors so don't know what if any would be the bottom line savings.
All rooms in the home have ceiling fans but it seems running one blower fan would be less expensive then running 4 or 5 ceiling fan motors.
Thanks for any advice you can afford me.
There should be an electrical rating for the furnace on the model # info inside the unit. In general those motors draw at least 3 amps unless they are the high tech ECM variable speed type. Watts = volts x amps. 120 volts x 3 amps =360 watts. Approx 1/2 a kilowatt. I pay 8 cents/kwhour so it would cost about 4 cents/hour x 24 hours/day = $1/day to run the average PSC standard motor. An ECM motor uses about 80 watts. If it makes the house more comfortable it may be worth it. But it will wear out the motor sooner and the electricity ain't free.
Appreciate the input, thanks
