CHATTANOOGA, Tenn. (WDEF)- EPB aims to assist residents and lower heating costs ahead of the winter weather. “A few tips we have is that we do recommend that you keep that thermostat set as low as possible, but still be comfortable in your home. So you know, if you can stand it at 70, put it at 70. If you can stand at 68 put it at 68 and we do recommend adjusting the thermostat one to two degrees at a time,” Nate Thomasson Engergy Pro with EPB.
