No, not without making some major changes in the heating unit. Even then, I'd question whether it was safe or not. It would be cheaper and safer to buy a 120 volt unit if one is available. But, the heat output on a 120 volt unit will not be the same.

Can a dimplex baseboard heater rated at 208v be connected to a 240v system


if you want to risk burning your house down . call an electrician and see what they can do to reduce the line voltage you have .

I need to wire a remote thermostat to my electric wall heater in the bathroom. Not sure if I run the wire from the panel to the heater first or to the remote thermostat then the heater.


Run the wire to the thermostat then to the heater

Can a 240 volt outlet be ran off this breaker and can a 240 volt electric baseboard heater be wired to it or should i use double pole breaker?


You need 240 breaker:
Notice that your 240V breaker is twice as wide as regular 120V breaker.
Notice that both switches are tied together on 240V breaker, making this a double-pole breaker.

No hot or warm water what is the voltage reading susposed to be on the heating elements? I have 122 volts on each terminal on both elements but no action, what am i doing wrong?


If water is totally cold, then upper element is not getting 240V. Since element tested for 120V, then that says upper element is burned out, upper thermostat is bad, or circuit breaker is bad.
Best thing is to buy multimeter and do 30 minute troubleshoot:
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

Also read information below for understanding how water heater works.

Testing elements for voltage can be misleading.
If water heater has 2 elements, then tank is 240Volts.
240V water heaters have 120V on each element at all times.
So elements have hot 120V power, but they are not turned on until the circuit is complete with 240V.
Open following links to read specifics about 120V and 240V
http://waterheatertimer.org/B220C.html
http://waterheatertimer.org/How-water-heater-thermostat-works.html

240V is made from two 120V Hot wires from breaker box.
Each 120V line from breaker is called a 'leg.'
So 240V circuit has two legs, and both legs need to be turned on to complete 240V circuit.

Water heater thermostats turn off only one leg.
The other leg is Hot all the time.
So when you test screws on an element, for example test between a screw and any bare metal part of tank, then the screw will always show 120V.
That is just one leg of the 240V circuit.
But the 240V circuit is not turned On until both legs are connected.
Every residential circuit needs two wires to complete the circuit, and in the case of 240V, those two wires are both 120V.

When the thermostat turns on, it turns on the second leg to the element and that completes the 240V circuit.

Where do i connect load wires to 240 volt baseboard heater


this is tricky to some you must connect heater to the load side of thermostat must will have a black set and a red set wires look at the directions to find the line side which you hook wires from panel to them I will tell you some switches are different so with out seeing the schmatics its hard to tell you email me a picof thomastat and i can tell you hope this helps

I have 2-240V (4.2V) basebaord heaters, Need Wiring Diagram


you get 120V from any phase (black OR red) to neutral
you get 240V from phase to phase (between black and red) and in this scenario you don't need the white wire.
So for you, connect the black to 1 pole of the breaker and the red to the other pole, connect the green wire to the ground strip and you are done.
A white wire is NEVER connected to a circuit breaker anyway, it is a grounded wire, it would be like connecting a green wire to a black wire, bad idea.
the National electrical code specifies red and black wire color for 240VAC circuits.
As Ask Hank mentionned, nothing wrong with 10/3 wire.

Heater is excessivly noisy, can be heard over tv


first, my research into the Cadet model #09954 is a 240v unit. if it is wired to only 120v that may be your problem. I am not even sure it work work on 120v.

Properly installed electric baseboard heater won't work.


I am an electrician. You must measure the voltage across the black and red wires. Measuring each wire to the neutral will not cut it. If both your red and black wire are on the same phase the heater will not work.

To double check your wiring, measure the voltage across the two screws feeding your subpanel, they should be 240v or 208v depending on your power company. Then do the same at the breaker feeding your thermostat. Again it should read 240v.

If you have no potential across the screws it is possible that you installed an incorrect breaker. Not all breakers with two screws on them are 240v breakers. There is what is called a twin or split breaker that has two screws that are on the same phase. These are for wiring two 110v circuits, when you run out of spaces in the panel.

Double check everything. This is a relatively easy circuit to wire, even for homeowners. If the heater does not work them something is wrong so do not leave the circuit energized.
