Ever try wearing a sweater instead of touching the thermostat? I used to bump the heat up right away, but keeping a blanket on the couch fixed that for me. Now I stay warm without the guilt of wasting energy.
But what if you actually need the heat? I mean, a blanket is fine on the couch, but what about when you're walking on cold floors or just getting out of bed? Idk, maybe it's just me, but sometimes cranking it for a bit is the only thing that really warms the whole place up fast.
