They don't work below a certain temperature because condensation collects on the cool side, creating frost, and makes them less efficient than baseboard radiative heat. The lower boundary is about -10c. Not to mention gas is just way cheaper than both of those options. But it does emit greenhouse gas. I don't know why this topic comes up so much recently. It's just not common at all where I am for a reason (Canada).
