Are space heaters silent? Here’s the honest answer.
If you’ve ever tried to warm up a bedroom, office, or living room with a typical space heater, you already know the truth: most of them are not silent. There’s usually a fan whirring, a motor cycling, or that faint clicking sound. It might be tolerable during the day, but at night or while you’re work? It can feel like a tiny airplane lives in your room.
So… are space heaters silent?
Most aren’t. But Kelvin is. And the reason comes down to a totally different kind of heating.

Why most space heaters make noise
Traditional space heaters usually rely on convection. That means they heat the air, then push that air around the room so the warmth spreads. To do that, they often need:
-
Fans
-
Blowers
-
Mechanical thermostats
-
Moving parts that expand and contract
Even “quiet” models still tend to hum, circulate air, or click on and off. Noise isn’t a bug in these heaters — it’s part of how they function.
Infrared heaters, like Kelvin, work differently.
Infrared heating: warmth without the noise
Infrared heating is one of the most efficient and comfortable ways to heat a space because it warms the objects and people in the room first.
If you’ve ever stood near a fireplace and felt cozy instantly, that’s the same principle. The warmth feels natural and balanced because it’s radiant, not windy.
Why choose infrared heating?
Infrared heating has become popular for one simple reason: it delivers comfort with less waste.
Here’s what makes it stand out:
Completely silent
No fans. No moving parts. No motor noise. Just steady heat.
Energy-efficient by design
Because infrared warms objects directly, the warmth is absorbed and slowly released back into the room. That means you don’t need to keep blasting heat nonstop to feel comfortable.
Many people find they can turn the temperature down a few degrees and still feel the same level of warmth — which saves energy without sacrificing comfort.

Kelvin Infrared Space Heater
Kelvin takes all the natural efficiency of infrared heating and adds smart, modern control, all while being completely silent.
It’s designed for people who want a heater that feels great, runs efficiently, and blends into daily life without fuss.
Whether it’s for a home office, bedroom, living space, or a calm environment like a studio, Kelvin is built to deliver warmth quietly and intelligently.
Key benefits of Kelvin
1. Cost-effective heating
By using infrared technology, Kelvin heats more efficiently than traditional space heaters. That translates directly into lower running costs over time.
2. Smart control in the Boldr Energy app
Kelvin can be managed from your phone, letting you:
-
monitor energy use
-
adjust temperature
-
set schedules
-
control heat remotely
So you can stay comfortable without heating your space unnecessarily.
3. Maintenance-free design
With no moving parts and a solid infrared panel build, Kelvin requires essentially zero maintenance.
Plus, ongoing software updates mean its performance and features keep improving over time.

Kelvin - cost effective, smart electric heater
Smart features that prevent wasted heating
Kelvin doesn’t just heat efficiently — it makes sure energy isn’t wasted.
1. Smart zoning
Control each room independently where a Kelvin is placed. Heat only the spaces you’re actually using, and stop paying to warm empty rooms.
2. Remote access
Turn Kelvin on before you get home, or adjust settings from anywhere from the Boldr Energy app.
3. Cost monitoring
Kelvin tracks real-time energy use so you always know what it’s costing to stay warm.
4. Smart scheduling
Set heating routines that match your day. Kelvin warms your space when it matters, and stays off when it doesn’t through it’s Smart Scheduling feature.
Smart home compatibility
Kelvin fits smoothly into your existing smart home setup, working with Alexa, HomeKit, Apple Home, SmartThings, Google Home and Google Assistant for hands-free control.

So… are space heaters silent?
Most space heaters aren’t. Fan noise, airflow, and cycling parts are standard in traditional designs.
But Kelvin is different.
Because it uses infrared radiant heat — with no fans and no moving components — Kelvin is completely silent while still delivering fast, even, energy-saving warmth.
If you want heat you can feel but not hear, that’s exactly what Kelvin was made for.
