My husband was skeptical at first, but quickly realised that the simple controls are much nicer than dealing with all kinds of complicated menus. I usually turn it on for a targeted, limited time, fitting right into my routine, so in the end, I can say it suits us really well as an extra heat source.

What makes us different?
InstaWarm Pro allows for efficient zone heating—heating only the room you are currently using (such as your home office, living room, or bedroom) rather than wasting energy warming the entire house via central heating. Powered by advanced ceramic PTC technology, it reaches comfortable temperatures quickly and maintains them efficiently using the built-in thermostat and timer.
Not at all! No electrician, installer, or drilling is required. The InstaWarm Pro is a completely portable plug-and-play solution. Simply place it on a flat surface or mount it using the included hassle-free bracket, plug it into a standard UK wall socket, and enjoy immediate warmth.
The InstaWarm Pro offers a high heating output of up to 2,000 W, making it suitable for heating rooms of up to 51 m² (approx. 550 sq. ft.).
Safety is our top priority. The InstaWarm Pro comes equipped with an integrated overheat protection system and an automatic tip-over safety switch that immediately cuts off power if the unit is knocked over, ensuring complete peace of mind around children and pets.
The InstaWarm Pro is designed for whisper-quiet operation (operating at low noise levels around 16 dB). It is ideal for undisturbed sleeping in bedrooms, watching television in the lounge, or maintaining focus while working from home.
Advanced heating technology delivers rapid warmth while minimizing power consumption to keep electricity costs low.
No Installation Required
Plug it directly into any standard wall outlet for instant comfort—no wires, tools, or complex setup needed.
Built-In Safety System
Equipped with integrated tip-over protection and auto shut-off features for safe, worry-free operation around pets and family.
Wide Coverage
Powerful output efficiently warms large spaces, bedrooms, and living areas up to 51 m² evenly and quickly.

Fast heat that spreads evenly
Good supplementary heating shouldn't just produce heat — it also needs to distribute warmth effectively throughout the room.
That’s why InstaWarm Pro combines its powerful PTC ceramic heating technology with active air circulation. Warm air circulates across the room, making the heat feel noticeably more pleasant and even.
With adjustable heat settings and individualised temperature controls, you can easily tailor its performance to your personal needs.
Thanks to the integrated timer, you can also set exactly how long the unit stays on for.

InstaWarm Pro is more than just a portable heater. Thanks to its 2-in-1 functionality, you can use the device on cold winter days as well as during warm summer months.
In winter, the integrated PTC ceramic element provides pleasant warmth. In summer, the fan mode delivers a refreshing airflow with powerful air circulation.
This allows you to flexibly enhance comfort in your living room, bedroom, or home office — right where you are.

Comfortable heating with integrated safety features
Safety plays a crucial role, especially when it comes to portable heating devices.
That’s why InstaWarm Pro features integrated overheat protection and a tip-over safety switch. This provides extra protection for the unit if it becomes too warm or accidentally falls over.
With adjustable heat settings, you can also adapt the heating output to suit the situation and only use energy when it’s actually needed.

Individualised temperature control
Timer for convenient operation
Energy-efficient operation tailored to your needs
Not every moment requires maximum heating power.
With multiple heat settings and precise temperature control, you can easily adapt InstaWarm Pro to your desired level of comfort. As soon as less heat is needed, you can simply lower the output.
This makes the device particularly practical as a flexible supplementary heater when you don’t want to heat the whole house, but only the room you are currently in.
In fan mode, the device operates without a compressor or chemical refrigerants, relying on air movement to deliver a pleasantly cooling wind-chill effect on the skin.
2-in-1: Warmth in winter and a refreshing airflow in summer
With InstaWarm Pro, you don’t need a separate device for every season.
In winter
The powerful PTC ceramic element quickly provides noticeable warmth. Active air circulation helps distribute the heated air evenly throughout the room.
Ideal as a portable supplementary heater for:
Living room
Bedroom
Home office
Workspaces and guest rooms
In summer
The fan function sets the room air in motion, creating a refreshing airflow that feels pleasantly cool against the skin.
Please note that this is not a traditional air conditioner with a compressor. Instead of actively lowering the room temperature using refrigerant and an exhaust system, InstaWarm Pro provides cooling through air circulation and the resulting wind-chill effect.

Note on the cooling function
InstaWarm Pro is a portable climate-comfort device featuring a fan function and PTC heating technology.
This unit is not a traditional air conditioner equipped with a compressor, split system, or monoblock design using refrigerants and an exhaust hose.
The cooling effect relies on circulating indoor air to create a gentle breeze. This produces a pleasantly refreshing wind-chill effect against the skin, similar to that of a high-performance fan.
It does not actively reduce room ambient temperature in the way a conventional air conditioner does.
Perceived performance may vary depending on factors such as ambient temperature, humidity, unit positioning, room size, and duration of use.

Customer Reviews
Overall rating: 5.0 / 5 from 180 reviews.
In my sewing room, it has been handy because the safety features give me a bit more peace of mind. I found positioning it in the right part of the room made a difference. The warmth comes through quickly enough that I do not feel the need to leave it running for ages before sitting down. So far, it has done exactly what I wanted.
The room feels more comfortable sooner because it is convenient when the main heating does not need to be on everywhere. I found positioning it in the right part of the room made a difference.
We mainly use it in the bedroom before bed; it is much less bulky than the old heater I had before. It is most useful in the rooms we actually spend time in.
I was looking for a straightforward top-up heater; it is convenient when the main heating does not need to be on everywhere. I found positioning it in the right part of the room made a difference. I like having a separate option for the room I am using instead of adjusting every radiator in the house. The convenience is what stands out most to me.
I was looking for a straightforward top-up heater; it is ready to use as soon as it is plugged in. I was looking for targeted warmth, not a replacement for the boiler.
We tried it first in the back room; the heat feels strong for such a compact unit. It is most useful in the rooms we actually spend time in. For us it makes most sense as a room-by-room top-up rather than something to run in every area at once. I am glad I chose a portable option.
I wanted something simple for our living room, and it is much less bulky than the old heater I had before. It is a compact heater, so expectations should be sensible. The setup was simply a case of finding a safe position, plugging it in and choosing the setting I wanted. It has made working from home more comfortable for me.
I was fed up with turning the heating up everywhere, so I tried this in the study; it feels well suited to everyday, room-by-room use. I found positioning it in the right part of the room made a difference.
It has made the conservatory more comfortable because it gives a useful boost of warmth without heating every room. I found positioning it in the right part of the room made a difference. It does not dominate the room, which matters in a smaller space with limited floor area. It feels like a practical bit of kit rather than a gimmick.
I keep it near the conservatory, and it feels well suited to everyday, room-by-room use. I mainly use it for extra warmth rather than as the only heat source.
There is no fuss with it: I can use it only in the room I am actually occupying. I tend to use it in shorter periods rather than leaving it on all day. The fact that it does not need fitting or mounting was important because we are renting. So far, it has done exactly what I wanted.
This sits in my reading corner most days, and it starts giving off noticeable warmth very quickly. I mainly use it for extra warmth rather than as the only heat source. We have moved it from the office to the spare room and back again without any hassle. I have ended up using it more often than I expected.
We have a room that always feels colder than the rest, and it saves me from turning the thermostat up for the whole house. For larger open spaces I still rely on the main heating.
Once the weather turned colder, I started using it in a small home gym, and the warmth is noticeable within a short time. The room size and how well insulated it is obviously matter.
On colder mornings, I like being able to use it where I need warmth most. I use it as a top-up when a room feels colder than the rest of the house. The setup was simply a case of finding a safe position, plugging it in and choosing the setting I wanted. It feels like a practical bit of kit rather than a gimmick.
The first cold morning I tried it, it takes up very little floor space. I would judge performance by the room rather than the headline coverage figure.
It has been most useful in the room above the garage, where it is easy to store away when it is not needed. I still use the main heating when the whole house needs warming.
I use it mostly in my sewing room, where it warms the area around me faster than I expected. I use it alongside, rather than instead of, the rest of my heating. I like having a separate option for the room I am using instead of adjusting every radiator in the house. It has been a useful addition at home.
I like being able to heat one space at a time; it works well as supplementary heat rather than heating the whole home. I mainly use it for extra warmth rather than as the only heat source.
For the lounge in the evening, this has been surprisingly useful because it fits neatly beside a desk without being intrusive. I usually switch it off once the room feels comfortable. I appreciate the built-in safety features, although I still keep plenty of clear space around it when it is running. I like the flexibility more than anything else.
I wanted something simple for a draughty box room, and it is easy to store away when it is not needed. I usually switch it off once the room feels comfortable.

For someone who hates fiddly setup, the fact that it fits neatly beside a desk without being intrusive is a real plus. It is a compact heater, so expectations should be sensible. I have found it particularly useful during work calls when I am sitting still for long periods. I would buy it again for another room.
My partner and I share it between rooms, and I can use it only in the room I am actually occupying. I use it as a top-up when a room feels colder than the rest of the house.
For quick extra warmth in a cold spare room, I have found that it warms the area around me faster than I expected. I still use the main heating when the whole house needs warming. I tend to switch it on while I am at my desk and turn it off again once the room feels comfortable. It has been reliable for the way I use it.
