They become resistive electric heat around -5/-10.
They work just fine, but costs more. If you hire a joe blow to size and install, and they dont do a schedule J, they might undersize, leading to freeze.
If you've got a cheaper, non-variable $/BTU option, keep it for cold weather. We dont live in the UP tho, they're fine as your primary in maine.

Wrong btu output drops massively when you approach the op limits my 36k btu rated to -30 puts out 8k btus at -20.
Try fuckin heating your house @-20 with 8k btus, so many uneducated jackasses in this sub its ridiculous. And i install them for a living

Why the shit you people talking -30 like it's at all common? Yea, cap drops there, but we might get 8 hours of -30 temps in a decade?
Checked mine - i'm still getting nearly 30k/36k at -15f, the record low point this winter. Which was like maybe 8 hours. Since we expect these temps, any competent installer would size for the realistic scenario.
