The first cold night of the season hit, and my room felt like an icebox. I wasn’t ready to commit to blasting the central heating, so I grabbed the Greenhouse Thermostat Heater to see if that tiny plug-in device could actually warm a whole corner of my room… or if it was just another pretty little gimmick.
What Is the Greenhouse Thermostat Heater?
The Green Thermostat Heater is a compact plug-in personal heater designed for small spaces. It has a built-in thermostat, adjustable temperature settings, a timer, and a fan-style heating system meant to spread warmth around quickly. It’s marketed as an energy-saving alternative for bedrooms, offices, and small nooks.
Why I Tried It
My goal was simple: stop freezing in my room without running the full heater for the whole apartment. I wanted something I could just plug in beside my table, get warm air on demand, and move around when needed.
My Experience Using It
I’ll be honest, my expectations were low. But once I plugged it in beside my bed, I actually felt the warm air immediately. Not crazy powerful like a full space heater, but enough that I wasn’t shivering anymore.
I used it mostly at night. I set the temperature to around the mid-range and let it run while I worked on my laptop. The warmth stays concentrated within a few feet of where it’s plugged in, so for me, it worked perfectly as a personal heater rather than something meant to heat an entire room.
One thing I appreciated was that it didn’t trip my outlet or make any strange burning smell (something I’ve experienced with other small heaters). And every time I switched positions, from my bed to my vanity, it was easy to unplug it and move it with one hand.
Is it a whole room heater? No. But for sitting close to it, doing my skincare, typing, or reading, I found it genuinely helpful. I wasn’t expecting to keep using it daily, but I ended up doing exactly that.
Pros & Cons
Pros
- Starts producing warm air immediately
- Perfect for close-range use
- Lightweight and easy to move
- Quiet enough for nighttime
- Didn’t overheat or smell weird
Cons
- Doesn’t heat a whole room
- Works best only when you’re sitting or lying near it
- Timer buttons are small and a bit fiddly
Build & Feel
It has a smooth matte plastic body that doesn’t get hot to the touch. No weird chemical smell, even during the first use. The warm air coming out is steady and surprisingly comfortable… not dry or harsh.
Product Claims vs. Reality
- Claim: “Heats up your entire room.”
Reality: It warms your immediate area. My bed space, yes. My whole room? Not really. - Claim: “Energy efficient.”
Reality: It didn’t spike my bill in any noticeable way, so I’d say yes on this one. - Claim: “Fast heating.”
Reality: The warm air starts blowing instantly. Full comfort warmth takes a few minutes.
Is Greenhouse Heater a Scam?
From my experience, no. It works exactly like a personal plug-in heater should. But it’s not a full-on room heater, so if someone bought it expecting that, they’d probably be disappointed.
How to Use
I plugged it directly into the wall (not an extension), set the temperature to a medium setting, and left it near the space I wanted warmed. Using it by the bedside gave me the best results.

Conclusion — Would I Recommend It?
Yes, for someone who wants a personal heater for their bedside, workspace, or small corner. No, for someone expecting it to heat an entire room. I ended up using it far more than expected because it genuinely kept me warm, which is all I needed it to do.
