Let’s talk about something a lot of people wonder:
Do bathroom heater lights use a lot of electricity?
If you’ve ever stood under one on a cold morning, soaking in the warmth, you might have thought, “This is great… but is it running up my power bill?”
It’s a fair question. We all love to stay warm and comfy, especially in winter. But no one wants to waste power or get a shock when the electricity bill shows up.
What are bathroom heater lights?
First up, a quick refresher. Bathroom heater lights are those ceiling lights that do more than just light up the room. They also give off heat, and some even come with a built-in exhaust fan to pull out steam.
They’re super handy, especially during chilly mornings. You walk in, flick a switch, and straight away, you’ve got light and warmth right where you need it.
At Elite Electrical Solutions, we install lots of bathroom heater lights across the Sunshine Coast, in places like Noosa, Maroochydore, Coolum, and Buderim. They’re a common pick in both new builds and renos, and for good reason: they’re simple, effective, and make cold mornings way more bearable.
So, do they use a lot of power?
Here’s the short answer:
Yes, bathroom heater lights do use a bit of electricity, but only when they’re on, and they’re not meant to run all day.
Most bathroom heater lights use heat lamps. Each of these lamps is usually around 275 watts. If your unit has two heat lamps, that’s 550 watts. Some models have four lamps, which brings it up to 1100 watts.
To give you some perspective:
- A normal LED light bulb might use 10 watts.
- A microwave might use 1000 watts when running.
- A split system air con can use anywhere from 1000 to 3000 watts.
So yeah, compared to a regular light bulb, bathroom heater lights use more power, because they’re heating up a room, not just lighting it.
But here’s the key: you only use them for a few minutes at a time. Most people turn them on during a shower or when they’re getting dressed. That’s maybe 5–10 minutes, sometimes 15. They’re not running all day like a fridge or air conditioner.
Let’s talk about cost
If you’re the numbers type, here’s a rough idea:
Let’s say you have a 4-lamp bathroom heater light (1100 watts), and you use it for 10 minutes a day.
That’s 1.1 kilowatts × (10 ÷ 60) hours = 0.183 kilowatt-hours per day
If power costs around 30 cents per kilowatt-hour, that’s about 5.5 cents per use.
Over a month? Around $1.65.
Even if you use it every day, the cost stays pretty low.
So no, bathroom heater lights don’t drain your wallet, as long as you’re using them the right way. Find the right energy plan.
How to keep electricity use low
Here are a few tips to make sure your bathroom heater light isn’t using more power than it should:
1. Only use the heat when you need it
Most units let you turn on the heat and light separately. So if you just need light, don’t use the heat.
2. Turn it off when you’re done
It sounds simple, but lots of people forget. Once you’re warm and dry, flick it off.
3. Use a timer switch
Want to make it even easier? Ask us at Elite Electrical Solutions to install a timer switch. Set it to run for 10 minutes, then it turns off by itself. Easy.
4. Pick the right size for your bathroom
Too big, and you’re wasting energy. Too small, and you’re not getting enough warmth. We can help you choose the best fit.
5. Keep the room well-insulated
A bathroom with gaps or cold tiles will lose heat faster. Simple fixes like a door seal or bath mat can help.
Are bathroom heater lights worth it?
Absolutely. For the small amount of power they use, bathroom heater lights give back a lot of comfort.
There’s nothing worse than stepping out of a hot shower into a freezing cold room. That blast of warm air from the heater light makes your whole morning better. And because you only use them in short bursts, the cost stays low.
It’s one of those small upgrades that makes a big difference, especially during winter on the Sunshine Coast. Even though we don’t get freezing winters like down south, mornings can still be pretty cold, especially inland areas like Cooroy or Pomona.
