Wiring for 240 Volt wall heater

Circuits and connections for 240 Volt wall heaters

Questions about electricity:How do you wire a thermostat for a 240 volt heater?
I’m trying to install a 240 volt wall heater with a fan built into the thermostat. The heater has two red wires. The circuit breaker is a double so I guess I need to connect white and black (12-2 wire) to both poles of the circuit breaker and copper to the panel ground screws. Where should I place the thermostat in the circuit?

This wiring question comes from: Chris, a homeowner from Vancouver, BC.

Response from Dave:
Thanks for your wiring question Chris.

How to wire a 240 volt wall heater

Application: Wiring for 240 volt wall heater.
Skill Level: Intermediate to Advanced – Preferably performed by a licensed electrician or electrical contractor.
Tools needed: Basic hand tools Tool bag, power drill, drill bit and extension cord.
Estimated time: Depends on personal qualifications, ability to work with tools and installation of wiring.
Caution: Identify the control board circuit, turn it off, and label it with notes before working with the wiring.
Note: Installation of additional circuit wiring must be done in accordance with local and national electrical codes, licensed, and inspected.

Example of wiring a wall heater

Chris, based on the information you provided, I can suggest that you pay attention to the installation instructions that came with your fireplace.

  • Typically, a 240 volt heater will have three wires in the junction box or connection area.
  • A dedicated circuit contains 3 conductors, two will be the 240 volt line and one will be the ground wire.
  • Circuit size is determined by the required electrical load of the heater measured in watts or amps.
  • It is extremely important that the new dedicated circuit is correctly sized.

Types of Thermostats for Electric Fireplaces

  • There are generally two types of thermostats:
  • The thermostat is mounted directly on the heater, located at both ends
  • Or a thermostat placed on the wall of the same room where the heater is installed
  • The thermostat will be related to the size and type of wire required by the electrical circuit or some thermostats are low voltage type where the control circuit is contained inside the electric heater.

IMPORTANT: Refer to the heater installation manual for circuit dimensions and specific installation instructions.

Installing a 240 Volt Support Heater: 5 Easy Steps

Here’s how you can install a 240v radiator in 5 steps

Step 1: Route the power cables

To get started, start by turning off the power to the heater. Carefully inspect and locate the wires and screws on the wall.

Remove the cable compartment cover. And select the side where you want to make the wired connection.

Remove the slotted outlets from the cable compartment and insert the cable clamp connector. You will need to route the power wires through the strain relief connector.

Most baseboard heater manufacturers do not supply a strain relief connector with the product. In this case, you will have to buy them separately. We present to you the following cheap cable tie connectors which will give you excellent value for money –Product-1 Product-2

To wire a wall thermostat, you will need to route the power cord a bit. Route the power wire from the circuit breaker to the thermostat, all the way to the end of the heating element.

Step 2: Install the baseboard heater

Locate the screws on the wall behind the fireplace using the stud finder.Find studs without rivet findercan be a bit difficult. But you can find the studs by estimating the distance between the studs and the socket.

Try to hit the wall 16 inches from the wall. If the knock sounds like a “knock”, you’ve definitely found your fingernail!

The fireplace must be attached to at least 2/3 of the wall studs. Secure the heater to the wall studs before connecting the ground wire to the ground screw. The ground screw is usually green as an indicator.

Step 3: Connect Baseboard Wire

Before wiring the water heater, you must first check the voltage and the circuit breaker.

Almost all motherboard heatsinks require three power cords to operate. If you are using a 240V heater you will have 2 hoes and 1 earth to wire it up. No neutral is required for wiring a 240V heater.

Connect the other power wire to the second hot wire. Use black tape to wrap the white wire to identify the hot wire.

Turn on the power at the main control panel after screwing the compartment covers back on. Pay attention to maintenanceColor coding for home wiringcorrect.

Step 4: Connect the circuit breaker

Now that we’re done with the wiring, it’s time to connect and install the circuit breaker.

Your 240v baseboard heater will require a new 20 or 30 amp double pole circuit breaker. New wiring is also required to power many heaters. The circuit is dedicated to the heater only.

Find an empty slot in the control panel to install the circuit breaker. Then turn on the main circuit breaker after closing the control panel. For easy identification, highlight the dashboard index. You will also need to determine if the white and red wires are hot by bonding them to black.

Step 5: complete the installation

Run your heater on the highest setting for about half an hour. You may notice smoke coming out of the fireplace. Do not worry about that. These are just residues from the manufacturing process.

If everything is working correctly, the heater has been installed successfully.

In the event that the machine begins to overheat and suddenly shuts down, immediately turn off the circuit breaker. If the heater does not start, check if there is somethingtrip the knife.

Additional hints

If you are replacing an old heater with a new one, check the circuit breaker first. Operating the heater at a higher voltage than recommended could damage the unit. Likewise, a low voltage supply will prevent the heater from heating up properly.

It is better to useswitched GFCI outletfor your fireplace. They may indicate tripped circuit breakers.

And finally, always remember to maintain safety measures before approaching the activity.

Frequently Asked Questions

Question: Can you run a 240v water heater on 120v?

To respond:It is possible to run a 240v heater on a 120v circuit. But even if there is no big security risk trying, you will face performance issues. A 120v circuit will not provide enough power for your 240v heater. Thus, your heater will give off less heat and may sometimes stop working.

Question: Do double pole circuit breakers need neutral?

To respond:The double pole circuit breaker does not need a neutral. The double-pole circuit breaker supplies a supply of 240 V, 20 to 60 A. In this case, it only needs two hot conductors. On the other hand, if it is a 120v device, it will need two hot and neutral conductors.

Question: What size wire is needed for 240V?

To respond:Running a 240V appliance with a 20A circuit breaker will require at least 12 test leads. The larger the circuit breaker, the larger the wire required. You should opt for 10 test leads for 240v devices.

I am not much for home wiring projects so I was a little intimidated by trying to wire in a 240 volt heater but after reading, researching, and talking to a lot of people, I figured i could handle this little project. I did have an actual electrician install the 240/30amp outlet in my garage some time ago so I didn’t have to worry about adding anything into my main panel. I don’t recommend messing with anything in there as that could very easily kill you! Now a contactor is really just a relay for AC power that provides a safer, more reliable way to turn on and off heavy loads. There are a lot of videos out there that show garage heater installs, but I haven’t seen any that install a heater in this manner, so I figured I would show you all how I did mine. Running the wire wasn’t bad, and wiring it was pretty straight forward once I understood what I was looking at. Lastly, yes, I tied my heater into my RV outlet. I know I probably shouldn’t do that, or try to use both of them at the same time, but I won’t, and I will definitely change this in the future. Remember, I AM NOT AN ELECTRICIAN!

Update: I have been calling my outlet in my garage an RV outlet, I was mistaken, this is not an RV outlet. This is a 240/60amp service which is much more than what an RV would take. Just wanted to clarify that.
