Im looking to save some money this heating season and one thing I was thinking about doing was having the blower speed set to low. I have a Trane xv80 with variable speed blower. I keep the blower set to on during the times we are home which keeps the air circulating at a lower speed all the time. The speed is currently set to mid-low.
If the speed gets reduced to low I think the heat output temperature will increase, but will this increase or decrease the amount of gas that will be used? What about electricity - will there be a meaningful cost decrease on low speed?
When I am away during the day( approx 8 hours) I have the temperature lowered and the blower off. If keep the blower on during this away time, will this keep the house warmer so that the recovery period will be easier?
Thanks in advance for ideas about this.
