Oh man, the struggle is real! Half of our lower level is below grade too and on a concrete slab and I think both of those things contribute to the challenge. I've just grown weary of the HVAC contractors' theories of how to fix the problem. The only other possible fix would be to run larger ducts and registers lower on the wall, this would require cutting into the drywall. So far none of their ideas have made any difference and have only costed us major $$$.

I think the wood stove will be a nice back up heat source and would be nice aesthetically. Unfortunately the auger that feeds the pellets into the stove runs on electricity but I think I'm going to buy one of those larger battery power banks for emergencies. The larger ones should power the auger on the stove for 5-7 days. We can use that for camping and roadtrips too.

Our portable infrared heater has been our savior. We bought one in 2016 and have used it in multiple apartments and now at the house.

Thanks! It's been a long road to (almost) 80. I just discovered PeakD rounds up. Yes, my family in Ohio said they're getting drenched.
