Hello,

I wanted to inquire about the 208/240V ratings that are available in most electric baseboards. Does it mean that the baseboard is compatible for 1-phase, 208V as well as 1-phase 240V connection? And also that when connected to 1-phase, 208V the output wattage would be 25% lower than, when connected to 1-phase 240V?

Thank you.

Yes.

And all that means is that it would have to run longer to heat up a room the same amount. Less watts, more time, same kWh.

Yeah, less watts & more time...but also due to slower heating rate @ 208V may require more heaters &/or better [higher R number] insulation system in colder climates in order to attain desired room temperature - see ASHRAE standards, prevailing building codes, etc.

208 Volts is common in larger apartment buildings and condos. Most users are not aware that the heating of baseboard heaters, electric stoves, clothes driers and similar 208V/240V appliances is taking longer.

Probably because the architects, engineers, designers and tradespeople have all done their jobs reasonably well...[smile]
