Re: electric baseboard heater
Typically, 240v baseboard heaters are approx 250 watts (or about 1 amp) per foot. At approx 2 amps, the resistance should be around 120 ohms. I would imagine a 120-volt heater of the same size would have half the resistance, or around 60 ohms.
The best bet would be to contact the manufacturer.

Re: electric baseboard heater
I would hook it up at 120 volts and see if it gets hot. A 240 volt heater operating on 120 volts will only produce 1/4 of it rated heat output. This should be obvious if the heater only gets warm.

Re: electric baseboard heater
Shouldn't that be 30 ohms for 120V?

Re: electric baseboard heater
For the samw power density, yes. I don't know if 120v baseboards are the same wattage per foot. You certainly may be correct.Originally posted by electricman2:

Re: electric baseboard heater
if i rember right the 2 foot baseboard heater useally rated either 250 or 350 or 500 watts depending on what voltage it is running i know there is 250 or 500 watt verison on 120 volt side but you can goggle the baseboard heater manufacters like Qmark i know one of them do make baseboard heater and few other do make it
Merci , Marc

Re: electric baseboard heater
If you don't know anything about them, are you sure you want to use them? For an extra cost, you could have them hauled away and buy something that comes in a box and that comes with the manufacturer's instructions. You might want to consider that cost in comparison to the potential cost of inadvertently making a wiring error.

Good point Charlie. Most of us would spend more than the cost of a 2' baseboard during a night out on the town.

Re: electric baseboard heater
I had an electrician at my house yesterday, giving me an estimate for a main panel replacement and some other work. I asked about replacing a pair of 4 foot baseboard heaters in the dining room area. They are over 10 years old, and put out almost no heat at all. He convinced me that it would be better to replace them with forced air units, instead of baseboard units. Better heat, better circulation of warm air, and about the same installed cost. Might be worth your looking into as well.
