The Black Wires from the md26 are your load(the heater) and the red lines are your line(power). The lines are also paired up on the thermostat with a red and black on the left and are red and black on the right. In the actual heater connect the black to the black wire and the white to the white and connect the grounds. In the thermostat connect the black from the heater to left side black( remember there are pairs left(black, red) right (black, red) and the white to the right side black connect the black from your power to the left side red and the white from your power to the right side red. Should be ready to go.

These are only 1500 watt heaters.

They 'could' heat a 20 x 20 foot room (with good, tight construction), with a slow temperture rise.

SOURCE: what braker for 240 volts 500 watts 2-1 amps

if you are running a new circuit for this one heater than a simple 2-pole 15 amp breaker will do fine, it is also acceptable to use a 2-pole 20 amp breaker, as long as you are in the united states. since you have such a small unit you can put 7 of these heaters on one 20 amp breaker.

I have a new heater with diferant terminals from the old one so not sure how to atach the wires


There is no need to rewire the internal of the heater!
Just bring in the electrical supply to the heater, it can be either 120 or 240 volts.
If the heater you have is like the picture associated with your post, then all then have to do is change the supplied plug from 240 to 120. It comes pre set for 240. That plug is inside the cabinet.

If any other brand, then you need to change the wires at the transformer of the heater. All heaters need to be supplied with primary voltage: 120 or 240. Then the control system is supplied with secondary voltage out of the transformer. The secondary voltage is no more than 28 volts. and these wires are normally colored as blue or yellow.

Secondary power is already wired within the heater. NO need to change where they are. You will only need to deal with the Primary wiring.

There are many varieties of transformers that transform high primary voltage to a low secondary voltage of 28 volts. and these transformers have many wires: primary & secondary.
I will try to make this easy to understand.

If you have a Gas Heater Transformer with these colors:
  • Red
  • Black
  • White
  • Green
Or...
  • Red
  • White with Red Stripe
  • Black
  • White with Black Stripe
  • Green
These are Dual Voltage Transformers, you can bring in either 120 Volts or 240 Volts

If you bring in only 120 Volts...
1st example:
The Red wire will not be used! Hot wire to the Black, and the Neutral/Common, to the white wire. Green to ground.

2nd example:
Connect the Red wire with the White with Red Stripe together and connect these to the incoming Neutral/Common wire, normally White.
Connect the Black Wire with the White with Black Stripe to your incoming Hot Wire, which is normally Black.
Green to ground

If you bring in 240 Volts...
1st example.
1 Hot wire to the Red, the Other Hot wire to the Black, and White wire is not used. Green to ground

2nd Example:
Wire nut the two Striped wires together. then one incoming Hot wire to the Black, the other incoming Hot wire to Red.
Green to ground

Or This is only a Low voltage - 120 Volts Only
  • Black
  • White
  • Green
Or either any of these combinations...
  • 2 Blacks w/Green
  • 2 Reds w/Green
  • 1 Black, 1 Red w/green
This type will only be a high voltage, 240 volts only
Picture below is what a transformer looks like and it is where your incoming supply wires go. The smaller leads with the spade connections will go to a specific location & is the 'Secondary" .

Good Luck

You need to take a meter and see if you have 220 volts between the black and white. if you do have 220 then hook white wire to the red on the on the thermostat and the black to the black wire on the thermostat. on the other side of the thermostat hook the red and black to the red and black to the heater

Hello Fixya Guru ! I am in the process of installing several Marley PLF series 2000 watt/ 240 volt electric "Hydronic" baseboard heaters. I am using 10/3 bx with a 30amp breaker. To my...


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.

Charlie

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.

1st you will belucky if you actually have 240 v, most
homes are usually 220v. In youyr case you need to start at the breaker panel.

This is an example:
You have a Double Pole Single Throw breaker. Black
Wire is hot and goes into one side of breaker,if you havea red wire that goes into the other have of the
breaker.

The white wire ties in the nuetral bar and the bare wire into the ground bus bar. At the unit you hook up the red and the black wire which will supply the 240
Volts, you could tie the white and the ground wires together into the grounding terminal

240v/750watt heater on 20amp


Yes, a 20-amp, double pole breaker will easily support that heater.

The calculation:

Watts = Volts x Amps

750 watts = 240 volts * x

x = 3.1 Amps

Maytag model MDE7057AYW 5600 Watts dryer runs ,but


5600 watts will not operate off 120 volts.
This is a 220/240 volt hookup.
There are 2 legs of 120 volts each that operate the dryer.
The only part requiring 220v is the heater.
Otherwise 120v routes through the various controls and relays.
