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 the UK are saving big on their energy bills with this innovative £49 heater. Our testing showed that the Warmool heater has the highest heating performance while staying the most energy efficient.
Warmool Heater ended up being leagues ahead of all the other portable heaters we tried. It passed every test with flying colours, including the most important one – rapidly heating homes to keep us warm throughout winter
Many of Warmool Heater’s fantastic benefits are due to its advanced new features, which have never been seen in a portable heater of this kind until now. All the other devices out there need to take note – this is the next-gen tech we need for 2023. Here are 5 reasons why Warmool Heater obliterated the competition this winter.
1. Reduce your energy bill.
Warmool Heater comes with the latest generation of ceramic heating, a smart technology which keeps the heat in the room for longer without the need to keep wasting energy. With this cost-saving heater, you can quickly turn your desk or bed from cold and frigid to warm and cozy. It’s brilliant.
2. It heats up 10x faster than traditional heaters.
Unlike traditional central heating systems that take up to 1 hour to heat an entire home, with Warmool, you can feel the warm air instantly blowing in your direction with a simple press of a button.
3. It's lightweight and portable.
Forget about lugging around ugly and bulky heaters. Warmool Heater’s dynamic design allows it to be set up on any table, desk, countertop, or flat surface. The heater plugs into a standard outlet, so you can take this device with you wherever you go to make your environment more comfortable.
4. It improves air quality.
Warmool is the perfect solution for those who suffer from allergies. It also filters dust, unwanted bacteria, and prevents the growth of mould, leaving you with fresh, clean air unlike other heaters that give off a musky unpleasant odour.
5. It had a waiting list of 10,000 people.
When launched originally, Warmool was flying off shelves faster than you could imagine! So much so, that there was a list of 10,000+ people, eagerly waiting for a re-stock. As of April 20, 2025 it’s finally back in stock, if you want to secure one act fast and claim the exclusive 50% off discount while it lasts.
Thousands Of Britons Have Already Made The Switch
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.
How Much Does It Cost?
Normally a portable heater of this quality would easily go for £200+ so one would expect the Warmool device to be in this price range as well.
Usually this heater sells for £110 which would still be a great deal given all the features. However the company has recently announced a limited time 50% off sale bringing the price down to just £49 on their online site!
That is a small price to pay in order to stay warm and cosy all winter long without spending £1000s!
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.
A Recent Problem with Availability
Due to frequent media coverage, high consumer demand and a 50% Off sale, the Warmool has become very popular amongst many people in the UK.
That and some recent supply chain difficulties has lead to the heater being out of stock frequently.
Make sure to check stock levels and order only from the official website HERE.
If you’re still on the fence about it, just remember that the Warmool Heater comes with a 30-day money back guarantee, no questions asked.
So if you’re not sure, you can always buy one and just return it later if you don’t like it.
