ceiling panel heater (electric resistance)
Does anyone have experience and brand recommendations for low-temp, low-wattage (probably well under 1000 W) ceiling panel heaters? That is to say, indoor electric-resistance radiant heaters that run off 120V power.
I was thinking about slightly undersizing my ductless mini-split system and using a handful of electric resistant heaters to supplement on, say, the 5% coldest days. These heaters could also help smooth out temperature gradients throughout the house, and finally can also serve as backup heat if the mini-split fails altogether.
Mind you, I know that many mini-splits have electric resistance heaters built-in for dealing with sub-0 F conditions. But this town really bottoms out at 5 F, so I’m not talking about that kind of functionality.
