11 Space Heaters That Won’t Trip Breaker Boxes

Space heaters that won't trip breaker boxes draw less power. See why heaters overload a circuit, what to look for, and 11 options, four reviewed in detail.

Quick answer

Space heaters that draw 400 to 800 watts are the least likely to trip a breaker. The four picks here are the LifePlus 700W oil-filled, GiveBest 400W, VERSAINSECT 500W plug-in and Teioe 400/800W. Do not share a circuit with other big appliances.

During winter, it is important to make sure your home is comfortable. 

Cold temperatures can cause illnesses and physical problems, not to mention how hard it can be to go about your daily life when it is freezing in your house.

While your home may have a central heating system, you probably don’t need to heat every room. For situations like this, a space heater is an excellent solution.

Unfortunately, some space heaters tend to trip circuit breakers, which is inconvenient and frustrating. Not all of them will do this; some can run long without drawing too much power. 

Knowing your options for space heaters that won’t trip breaker boxes can help you find the perfect solution for your home’s heating needs.

Why Do Space Heaters Trip Breakers?

There are several reasons why space heaters will trip circuit breakers in your home. One of the most common reasons is that the heater plugged into the specific circuit is overloaded. 

Your home most likely has several circuits, all of which power different areas of the house. Space heaters draw a lot of current from household circuits, which can overload them, which triggers the breaker to trip instead of heating up and starting a fire. 

This usually happens when the heater is plugged into a circuit with other high-current items, like refrigerators and dishwashers. Plug any space heater directly into a wall outlet, not an extension cord or power strip. 

Space heaters that won’t trip breaker boxes generally have a lower wattage. A 1,500 watt heater draws about 12.5 amps (watts divided by 120 volts), most of what a common 15 amp circuit can carry, while a 500 watt heater draws about 4 amps. 

Because of this lower wattage, they don’t draw as much power from the circuit, keeping them from tripping the breaker. 

With a low-wattage space heater you have much more room on the circuit, but it can still trip the breaker if the same circuit also runs a refrigerator, dishwasher or other high-draw appliance. You can also run it without going down to the basement to flip the breaker switch.

What to Consider Before Buying Space Heaters That Won’t Trip Breaker Boxes 

Before you start shopping for space heaters that won’t trip breaker boxes, it is important to know what to look for. 

Understanding your needs and the specs of different space heaters will help you make the best decision. 

Room Size 

The room size you are trying to heat is one of the most essential factors when picking space heaters that won’t trip breaker boxes. 

The higher the wattage is, the more hot air the space heater will put out. It will also draw more current from the circuit and increase the likelihood that the breaker will trip. 

Most standard space heaters are 1,500 watts. However, you can find heaters that are as little as 400 watts. 

Space heaters that won’t trip breaker boxes are usually between 400 and 800 watts. 

Finding a happy medium between a powerful heater for the size of the room you want to heat but with a low enough wattage to not trip the breaker will be your best bet.

Price of Operation 

The price to run your space heater is also an important consideration. 

Depending on where you live, power may be more expensive than in other areas. Fortunately, a space heater that won’t trip breaker boxes will also be cheaper to run. 

Home electricity is sold at a certain price per kilowatt-hour. One kilowatt-hour is the energy a 1,000 watt appliance uses in one hour. 

Since most space heaters that won’t trip breaker boxes draw less than one kilowatt, they will be cheaper to run than the heaters that are over 1,000 watts. At the U.S. average residential price of 18.31 cents per kWh (July 2026), a 500 watt heater costs about 9 cents an hour on its highest setting and a 1,500 watt heater about 27 cents. 

Average Temperature

Before deciding on a space heater, consider how cold it gets in your area. 

If it regularly gets into the twenties or below, getting a higher-wattage heater may be worth it. If, however, your winters only average the low-to-mid 40s, you can most likely stick with a small, low-wattage unit. 

Knowing your needs and how cold it gets where you live will help you make the best decision when shopping for space heaters that won’t trip breaker boxes.
