ENERGY EFFICIENT
We found the Warmool Heater to be 50% more energy efficient than all other devices.
We Bought & Tested The Most Popular Heaters, Here’s Why Warmool is our #1 Pick
Summary: Thousands of people in Ireland are saving big on their energy bills with this innovative €59 heater. Warmool is a powerful portable heater that puts a stop to bone-chilling coldness. Our testing showed that the Warmool heater has the highest heating performance while staying the most energy efficient.
UPDATE April 18, 2025: Due to frequent media coverage and high consumer demand, Warmool is currently sold out in retail stores nationwide. However, it may still be available on their online website HERE.
I grew up in Washington before moving to Ireland and remember living practically next to the heater during the winter months, whether it was reading comics, doing homework, or watching TV.
But after a kid at my school got badly burned from touching the smouldering 200°C metal on their Heater, I didn’t dare to be close to my family’s heater ever again.
Instead, I had to get used to wearing layer upon layers of clothes.
I’ve tried portable heaters before, but I’ve never been impressed!
They usually sound like my vacuum cleaner, but constantly.
And they don’t produce nearly enough heat to cover a big room, yet they scorch me if I stay too close.
And yes, I’ve seen some of the more expensive “portable” heaters on the market, but come on.
They look ridiculous, occupying the whole room like the monolith from 2001!
Can you imagine the power consumption of that thing?
Little did I know, there would come a time in my life when I would be praising a specific little portable heater that transformed my arctic cave into a lush tropical paradise.
And best of all, allow me to wiggle my toes freely now that I didn’t need 3 layers of socks!
First Impressions
The package we ordered arrived in a couple of days so we were off to a good start already. I personally hate having to wait weeks for something I ordered online to arrive.
Upon my first inspection I noticed something strange about the package, it was…tiny.
“Oh no, I’ve been ripped off!” I thought. The package was way too small to be a heater!
That’s basically how we as people have been thinking since forever. Isn’t it funny how we are always quick to reject new solutions, ideas and technology throughout history?
Look at the inventions of seatbelts, elevators or the idea of washing your hands before surgery, all of these ideas were rejected and opposed for many years before finally being accepted!
The point I’m trying to make is this: I initially thought that something so tiny couldn’t possible heat up a room and that I’ve been ripped off.
In reality, I should have been intrigued and grateful that I was about to review a new innovative technological idea!
Design
The problem with previous budget portable heaters that I had tested was that they were made with cheap, low quality materials. However after examining the Warmool Heater I was immediately impressed with it’s design. It was very light, making it easy to move from room to room but at the same time it had a very solid feel to it.
We’ve all experienced the difference of a cheap or brittle product and a high quality one, whether its sunglasses, clothes or shoes… well heaters are no different and this one felt and looked amazing.
Testing
Now it was time to dive into the testing. I was excited to see how this tiny device would perform. The instructions were really simple. just plug it into the well, set the desired temperature and press the power button.
I did all that and nothing seemed to happen. I rushed to find the instruction manual again, thinking I did something wrong.
After returning back to my room I felt a surge of hot air hit me. I panicked, thinking I left the stove on or something was burning.
In hindsight and probably to anybody reading this, it was obvious that the new heater was warming up the room. However at the time I still thought that it wasn’t working…
And why did I think that?
Because the heater was making NO SOUND AT ALL!
I was shocked because the heaters I tested previously made a very loud whirring noise which was very distracting whether I was trying to work, relax or sleep. The Warmool heater was remarkable silent yet very effective at heating up the room. Eventually I came out of my confused daze and realised where the heat was coming from.
Controlled Testing
After that little bit of confusion I decided to run a more controlled test to see how effective the Warmool heater really was.
This time I plugged it into my kitchen outlet since the mornings where I live are absolutely freezing. I cranked the temperature way up to 31 C just to stress test the heater and see how powerful it was.
I measured the temperature in the room at the start, it was sitting at a chilly 18 C… in just 7 mins I was sweating as the temp hit 28 C. I had it turn down cause of how hot it was getting but I was convinced that this heater is damn POWERFUL.
Energy Efficiency
During our testing we found the Warmool Heater to be extremely energy efficient. At it’s highest setting, it doesn’t use more energy than a standard hairdryer.
The average cost per kilowatt-hour in Ireland is around 20 cents. When we took energy readings from the Warmool Heater, it clocked in at around 22 cents per hour the unit is operational. That was at the HIGHEST heat setting.
We have had reports of people saving up to 30% on their electric bills using this device which can really help out during a cold winter.
Safety Features
Safety is another very important aspect to consider when buying a portable heater. You don’t want to worry about one of those old heaters which can tip over and set your house on fire.
Thankfully the Warmool heater was designed with complete safety in mind. The safety features include:
Tip Over Protection – In the case the Warmool is knocked over, it doesn’t immediately shut off. Instead, it blows out colder air for 30 seconds to immediately cool itself and its surrounding before cutting the power supply.
Overheating Protection -If Warmool Heater’s internal temperature gets higher than 50C, it will automatically lower it to 40C. If the new lower temperature isn’t reached within 30 seconds, or if the temperature goes up again and above 50C times in succession, Warmool will automatically shut down.
Flame Resistant Materials – The Warmool Heater is made out of flame resistant materials for extra safety.
What Else Can It Do?
More than you may think!
✅ Set Your Perfect Temperature – You can set the temperature at whatever feels the coziest for you.
Portable – The outer casing of the heater doesn’t get warm so you can move it from room to room easily.
Air Quality Control – The built in antimicrobial filter will catch dust and prevent any mold from growing. Great for people with allergies & pets.
Fast & Efficient – Don’t wait around in bone chilling cold, heat up any room in just minutes!
Lightweight & Easy to carry – Compact and easy to carry. It comes with its own carry handle.
Extremely Quite– This was the quietest heater we tested. Whether you’re working from home, relaxing watching the TV or having a nap, this heater won’t disturb you with noise.
Energy Efficient– Users have reported savings of up to 30% over the winter time using this heater.
But...Is It Really Worth All This Hype?
So far, the Warmool Heater has sold multiple thousands of units directly to consumers. It’s has been selling out every time they re-stock, it’s become THAT popular.
All of the success can be attributed to word of mouth referrals. People like you and I are loving it so much they’re posting about it on social media.
Here’s what people are saying about this revolutionary hearing aid on social media:
It’s clear that the Warmool Heater is developing a cult like following online.
Value For Money
Normally a portable heater of this quality would easily go for €150+ so one would expect the Warmool device to be in this price range as well.
Usually this heater sells for €120 which would still be a great deal given all the features. However the company has recently announced a 50% off sale bringing the price down to just €59.95 on their online site!
That is a small price to pay in order to stay warm and cosy all winter long.
How Can It Be So Affordable?
There are two reasons why the Warmool Heater is so affordable right now. One is that they sell only through their online store, saving the cost of renting out multiple brick and mortar stores.
The second reason is that big brands spend billions on advertising and pass all those costs on to the consumer unlike Warmool which just relies on word of mouth referrals for sales.
Purchase & Delivery Process
The Warmool Heater is easy to purchase as long as they are in stock. They offer free delivery & an iron clad 30 days return policy in the case that you are not satisfied with the product. We got our package delivered in just a few days.
