If you’ve ever stood in front of an electric fireplace on a chilly evening, feeling that gentle, warm glow but wishing you could tweak the heat just enough to skip reaching for another blanket or rolling up a window shade, you’re not alone. As someone who’s spent the last decade sourcing and fine-tuning electric fireplaces for homes across the country, I’ve lost count of how many customers stop by our showroom or email with that exact question: “How do I adjust the heat settings on my electric fireplace—especially when I want to balance comfort, energy use, and that cozy vibe without turning it into a space heater blast?” Electric Fireplace
Today, I’m breaking this down like I would for my next-door neighbor who just got her first electric fireplace and is still learning the ropes. No fancy jargon, no confusing tech terms, just straight-up, practical steps you can use, plus the little pro tips that come from working with these units day in and day out.
First, let’s start with the basics: why adjusting an electric fireplace is different from adjusting a gas or wood-burning one. Gas fireplaces let you crank up the flames with a dial, and wood ones rely on how much fuel you feed them, but electric units are controlled by electricity and thermostats—two things that give you way more precision, but also mean you have to know what each part of your unit does. Most electric fireplaces have two separate systems working together: the flame effect (that fake log, the glow, the crackling sound) which runs on low power 24/7, and the heating element, which only kicks in when you need warmth. That means when you adjust heat settings, you’re only tweaking the second part—so you don’t have to worry about messing up the cozy vibe if you decide you don’t need heat that day.
Let’s go through the most common setups, because there’s no “one size fits all” when it comes to adjusting heat. I’ve seen units with dials, touchscreens, remote controls, even wall-mounted panels, so I’ll cover each type you’re likely to encounter.
If your electric fireplace has a basic control dial (usually on the unit itself, near the bottom or back), this is the easiest to use. Turn it clockwise to increase heat, counterclockwise to lower it. But here’s the thing most people miss: that dial isn’t just an on/off switch with high and low. It’s connected to a built-in thermostat. So when you turn it, you’re setting the temperature you want the room to reach. For example, if it’s 65 degrees in your living room, turning the dial to “warm” will keep the heat on until the room hits around 68, then shut off the heating element temporarily until the temperature drops again. If you just want a little extra warmth on a 50-degree evening, turn it to the low setting—most basic dials have a “low” (usually 750 watts) and “high” (1500 watts) option, which is the standard for portable and smaller built-in units. I always tell customers to start on low first, even if they think they need more heat. 1500 watts is enough to warm a 400-square-foot room, so cranking it right to high from the get-go will blast you out of the room instead of making you feel cozy.
Next, remote controls—this is the most popular setup now, especially for wall-mounted or entertainment center electric fireplaces. The buttons are usually labeled with clear icons: a flame for adjusting the flame brightness, and a temperature or heat icon for heating. Most remotes let you set a specific temperature, like 68, 70, or 72 degrees, instead of just high/low. That’s a huge upgrade, because it means your fireplace will turn on and off automatically to maintain that number, so you don’t have to keep tweaking it every few minutes. A common mistake here is hitting the “heat” button without checking if it’s set to “energy saver” mode. Many remotes have two heat settings: high/low, and an eco mode. Eco mode keeps the thermostat running, but uses less power by turning the heating element on and off in cycles, instead of running it nonstop. If you’re only in the room for a few hours, eco mode is perfect—you get warmth without the spike in your electricity bill. I once had a customer who told me their electric bill went down 12% after switching to eco mode, and that’s not uncommon when you know how to use the right heat setting.
Then there are the smart electric fireplaces, which connect to your phone or a home assistant like Alexa or Google Home. This is the newest category, and honestly, it’s where the adjustment gets really flexible. You can set a schedule—like 5 PM to 10 PM, heat set to 68 degrees—so you come home to a warm room without having to do anything. You can also adjust heat from work, if you realize it’s going to get cold that night and want to pre-warm your living room. The key here is not overadjusting. Just because you can set it to 75 degrees in the middle of the day while you’re at work doesn’t mean you should—your unit will run all day, wasting energy. Stick to the temperature that feels comfortable for your daily routine, and use the schedule feature to match it to when you’re home.
Now, let’s talk about the settings you’ll find on almost every electric fireplace, because these are the ones that make adjusting heat easier, not harder. First, fan speed. Most units have a low and high fan setting. If you want gentle, diffused heat that feels like a natural fireplace, use low fan. High fan is good if you’re warming a room quickly, or if it’s extra cold outside, because it pushes the warm air out faster. A lot of people forget about fan speed and just crank the heat—switching to low fan on low heat is the secret to that cozy, not-too-warm glow that feels like a real fire, not a space heater blowing hot air at your face.
Then there’s the “auto shutoff” or “timer” feature. This is great if you like having the fireplace on while you fall asleep, because you can set it to turn off after 2 hours, 4 hours, or whatever works for you. I’ve had customers tell me they used to leave their fireplace on all night, only to wake up sweating and with a high electric bill—using the timer fixes that. When adjusting heat, pairing the timer with the thermostat is the best combo: set your desired temperature, set the timer for when you’ll be asleep, and your fireplace will take care of the rest.
Wait, but what if your heat isn’t adjusting like it should? I get this question a lot too, because even with these simple units, sometimes things go wrong. First, check the basics: is the plug fully inserted? It sounds silly, but a loose plug can make the heating element run on low power, making it feel like your adjustments aren’t working. Next, check the thermostat on the unit itself—if it’s covered by dust or debris, it can’t read the room temperature correctly, so adjusting the settings won’t do anything. Wipe it down with a dry cloth once a month, that’s a quick fix. Another common issue is placement: if your electric fireplace is blocked by a couch, bookshelf, or curtain, the warm air can’t circulate, so you’ll think the heat setting isn’t working when really it’s just trapped. Leave at least a foot of space around the fireplace for air flow, and that’ll help the heat adjust properly.
Now, let’s get into a few pro tips that come from being an electric fireplace supplier for years, because these are the things no instruction manual tells you. First, zone your heat. If you have an open floor plan, where your living room is connected to your kitchen, don’t set the fireplace to high heat—instead, use the low setting and close any vents that lead to other rooms. This concentrates the warmth where you are, so you don’t waste energy heating empty spaces. Second, adjust heat based on the outside temperature. If it’s 40 degrees outside, you might only need your fireplace set to 68 degrees; if it’s 20 degrees outside, 70 or 72 is enough. Going higher than that will just make the room feel stuffy, not more comfortable. Third, if you’re using your electric fireplace as the main heat source (instead of a secondary one), don’t forget to check your home’s overall insulation. A drafty window or poorly insulated attic will make your fireplace work harder than it needs to, so adjusting the heat setting to compensate will cost more than it should. Fix those small drafts first, and your electric fireplace will be more efficient.
I once had a customer come to me last winter who was frustrated because she adjusted her fireplace to high heat and still felt cold in her living room. When I came to check, I noticed two things: her couch was pushed right up against the fireplace, blocking air flow, and she was running the heat in the rest of her house at the same time, so the warm air was being pulled away. We moved the couch, closed the vents to the other rooms, and had her switch to eco mode on low heat—she said the next week was the first time she didn’t have to turn on her central heating all month. That’s the thing about electric fireplaces: they’re simple, but you have to use them right, which means adjusting the heat settings in a way that works for your space, not just the numbers on the dial.
Another thing I always emphasize: there’s no “right” heat setting. The whole point of an electric fireplace is comfort. If you like it warm enough to wear a sweater and socks, set it to that. If you prefer it a little cooler, even in the winter, that’s fine too. The goal isn’t to hit a specific temperature, it’s to feel cozy. I’ve had customers who love running their fireplace on low heat just for the flame effect, turning the heating part off entirely—this is totally normal! Electric fireplaces give you that flexibility, so don’t feel like you have to use the heat if you don’t need it.
If you’re someone who’s newer to electric fireplaces, I’d recommend starting small. Turn the unit on, play with the heat settings on low first, then move to medium, then high, and notice how the room feels. Adjust the fan speed up or down to match the heat level, and use the thermostat to fine-tune instead of cranking numbers. Once you get used to how your specific unit works, adjusting heat will become second nature—no more guessing, no more cold nights or overheated rooms.
As a supplier, I’ve spent years testing dozens of electric fireplaces, and the ones that sell best are the ones that are easy to adjust. At the end of the day, the best heat setting is the one that makes you feel relaxed, whether you’re reading a book on a Sunday afternoon or hosting friends for game night.
