Question about Fahrenheat Electric Convector Baseboard Heater, 240 Volt

We just bought a 3 ft Electric baseboard heater. 240 volts /750 watts3.1 amps. It doesn't seem to heat well. we just put a addition on to our home and put this is the bedroom we added on. Was wondering if maybe we have it hooked up wrong.. any suggestions. Its hooked to 110

The baseboard heaters out put goes down a lot more than you would think when used on 120 volts ... thats because not only is the voltage half of what it should be, the current is also half .. so the total power (the product of voltage and current) is one fourth of what it would be if operated on 240 volts .. you are operating at only 186 watts instead of the 750 watts you should have .. so you would have to have 4 times as many heaters for the same heat output .. you likely have the 240 volts available (most houses do) .. there are two phases .. each 120 volts .. when both phases are used together then you get the 240 volts total .. another option is you can use heaters designed for 120 volts .. the current would increase to a little more than 6 amps per heater .. some heaters have a jumper you can move for 120 volt service or 240 volt service... you can use those with either voltage ..

How much insulation in atic spce?cieling height? Assuming they are getting 220 volts,not 110?

You are correct that these heaters use a two-wire 240 volt supply, and the neutral is not needed.

2000 watts = 240 volt x Amps ==> Amps = 8.3 amps

30 amps x .8 safety factor = 24 amps

24 amps / 8.3 amps = 2.9 heaters per 30 amp breaker (3 heaters should be okay)

More info, pls let me know.

P.S. Where does the 2880-watt number come from ?

P.P.S. There has to be a ground bus-bar in the panel -- if it's a main panel (not a sub-panel) the ground buss and the neutral buss are connected in the panel. Could you clarify what you have in the panel.

My PLF504 detonated this morning (11-25-2010). It worked fine for two years then BANG. Room was lit by flame coming from center (left to right) of unit. I wrote Marley asking them to honor the 10 year heater element warranty. Also, no burnt wires at thermostat connection, no dust bunnies on the fins. Source of fire was the fluid filled encapsulated heater core. Thank God, circuit breaker tripped and wall was tiled.

HERE YOU GO CALCULATE THE HEAT @ 10 WATTS PER SQUARE FOOT , TAKE THE LENGTH X WIDTH X 10 AND THIS WILL TELL YOU THE AMOUNT OF WATTAGE YOU NEED . MOST ALL BASEBOARD HEATERS ARE RATED @ 250 WATTS PER LEN FT AS TO SAY A EX. A 4FT HEATER IS 1000 WATTS , MOST OF THE THERMOSTATS ARE RATED @ 20 AMPS AS IS THE 12-2-WG WIRE TO RUN TO HEATERS AND THERMOSTAT DIVIDE THE TOTAL WATTAGE BY THE LINE VOLTAGE USUALLY 240VOLT IN US .AND THIS WILL TELL YOU THE CURRENT DRAW ----WHICH CANNOT EXCEED 20 AMPS ON 12-3-WG AND THAT IS THE LIMIT OF THE THERMOSTAT AS WELL THESE STATES APPLY 99% OF THE TIME I DO REALIZE THERE ARE EX BUT HAVE USED THESE FORMULAS FOR 35 YEARS OF DOING MY WORK AND THEY DO FINE

check on the wiring diagram. You may be looking at 2-15 amp or 2-20 amp breakers.

take a close look at the tubular element with a magnifying glass. the volts value should be stamped into the element. most baseboard heaters are 240 volt at low, high and medium density. wattage could be from 750 to 1500 watts

a 750 watt heater at 240 volts draws 3.15 amps so a 2 pole 15 breaker with 14/2 wire would be fine

if the heater is 120 volt or 240 volt its really pretty easy. at either end is a cover. remove the cover and you'll see a wirenut or maybe just two wires. one side has an integral thermostat. connect your supply to the two wires on the thermostat. connect the other end in your breaker box with the appropriate sized circuit breaker. wire size feeding it will depend on its current draw. how many watts is the heater? 1500 watts will draw 6.25 amps at 240 volts so you can use 14 ga wire. 2000 watts will draw 8.3 at 240 volts - so 14 ga is still ok. 2500 watts at 240 draws 10.41 amps. 3000 watts draws 12.5 amps at this stage I'd use 12 gauge on a 20 amp breaker.
