P.S. I tried to get DH to install a Wave heater to help with battery use boondocking, but he declined b/c "The furnace will be fine for one night, Dear. For crying out loud, it's only 2 years old, let's use it first before we start adding expensive mods!"
LOL, he's a light sleeper, and after waking up every time the furnace kicked on (and sweating his buns off when it overshot thermostat control, yet another mod he declined to help me with... adding a Honeywell digital thermostat) he admitted that maybe a Wave is in our future.
