Winter is around the corner, so it is time to start thinking about updating the electric heaters in your home or business. Whether you are updating one or two heaters in your home, or you are renovating a commercial space and installing new heat options, you will need to know how much voltage, amperage, and wattage the circuit can handle.

Where do I find the voltage on my existing heater?
You can find the voltage of your heater on the product’s label:
What if I scrapped my old heater without checking the voltage?
If you are not able to figure out the voltage from the product label, you can check the circuit breaker to figure out the voltage. What Are The Different Types of Heaters?
To determine what your room or area can handle, start by examining your electrical breaker panel. Electrical circuit breakers should have their amperage marked on the toggle handle or on the top part of the module. Generally, a 240 volt circuit breaker will have a double pole due to the large supply of energy that is needed to power the heater. A 120 volt will normally have a single pole.
What if my breaker does not look like the pictures above?
No problem, some circuit breakers will look differently. In that case, you will need to use a voltmeter to test the power coming to the heater. This will require caution, if doing it yourself, because you will be testing live wires. It is suggested that you contact a licensed electrician when dealing with hazardous electrical wires. Choosing Between a Baseboard Heater and a Wall Heater?
You should never...Assume you know the right voltage. Hooking up the wrong voltage heater can be dangerous! If you are unfamiliar or uncomfortable with electrical wiring, please contact a qualified technician or licensed electrician.
Should I get a 120V or 240V electric heater?
If you are replacing your current heater with a new one, you want to make sure to match the power supply that you already have. If you are adding in a new heater, 240 voltage heaters are recommended because they have the capability to support more wattage.
However, we do not recommend hooking up a 240 voltage heater to a 120 volt circuit. Hooking up the wrong voltage heater to the wrong circuit will cause you to only receive 25% of the wattage it was designed to deliver. Check out our Employee's Choice Heater: Cadet CEC163TW
