Just be aware that Russell Hobbs doesn’t recommend that you use this product outside – and it shouldn’t be exposed to the rain. If you can afford it, the Dyson Purifier Hot+Cool Formaldehyde is a sterling choice for winter warmth and air purification. What’s more, when the summer months arrive, you can turn off the heater element and enjoy a cooling breeze instead. Safety features include overheat and tip-over protection. You’ll become aware of the latter the minute you take the heater out the box, because it feels like something is loose inside. Don’t panic, it’s part of the design. There are three speed settings – low, medium, and high – and then a toggle that you push in to make the fan oscillate left and right through 90 degrees, and pull out for static, directional airflow. Dyson Purifier Hot+Cool Formaldehyde purifying fan heater: Best fan heater-cum-air purifier for discerning stylistas

At this price, I expected the fan to be fairly noisy, and it is, especially on the medium and high speed settings. But whilst it definitely can't give the Duux Whisper Flex Smart Fan or MeacoFan 1056 Air Circulator a run for their money in the quiet stakes, it is still a lot quieter than the budget Honeywell Turbo Force Power Air Circulator Fan, and it's half the price and certainly looks far more stylish. The air it delivers certainly isn't as cold as the powerful MeacoFan 1056 Air Circulator can deliver, but it does make a difference when you're feeling hot and bothered. If you’re in the market for a saviour against the cold that’s easy to store away when not in use, then this dinky unit is most definitely worth the small outlay. MAXIMUM HEAT OUTPUT – Choose from 2 heat settings for complete flexibility during cold spells and winter months – 750W for low heat and 1500W for high heat. The limited settings are both a plus point – how nice not to be overwhelmed with 30 speed settings the Duux Whisper Flex Smart Fan boggles the mind with – but at the same time a little more variation would have been welcome in practice. You can take out the middle shelf entirely, which will allow you to fit in full-height bottles, such as the bottle of wine. Russell Hobbs says that it will hold two 1.5-litre bottles.

Unlike most fan heaters that blow out hot air from a front grill, here it is blasted out through the top of the unit in a 360-degree pattern. At just 30cm in height and 22cm wide, the Duux Threesixty 2 is unobtrusive – in fact, some may mistake it for a small waste paper bin. Despite the lower-quality build, we were impressed by this heater’s performance. It’s very keenly priced, too. For additional cooling space if you’re entertaining, added convenience in a home office or bedroom, the Russell Hobbs Scandi Portable Mini Cooler & Warmer does a good job of keeping contents cool, provided it’s kept out of direct sunlight. At temperatures above 25ºC, then, you’ll find that the inside of the cooler won’t get as cold as a regular fridge. Keep it out of the sun and hot rooms, however, and you’ll be fine. Nevertheless, the higher temperature variance means that, aside from temporary storage, I wouldn’t recommend using this cooler for items that can spoil, such as milk.

Second, compressors that use refrigerant are more efficient than the thermoelectric system used in the Russell Hobbs Scandi.

Take the edge off the colder months with our pick of the best fan heaters - they'll keep you cosy and warm while saving you money too

The controls aren’t very ergonomic or nice to the touch; they feel pretty basic. And the corrugated edges of the speed button in particular are quite uncomfortable to hold and left some big indents in the thumb after twisting through the settings. But, the controls are manual and don't involve any clever (faffy) touch screens or tiny (easily lost) remote controls to be operated, and they produce a good stream of air that has a cooling effect on a hot day. This retro heater is easy to use and features 2 power settings (750W and 1500W), an adjustable thermostat and fan only setting, making it ideal for use all year round. Build quality is excellent, it looks attractive and its compact size (it’s just 28.5cm wide and 16cm in height) means it won’t get in the way. It’s just the job for heating up a space without fuss. Using Dyson’s unique Air Multiplier technology combined with variable oscillation up to an impressive 350 degrees, the Hot+Cool delivers a good wallop of warmth. According to the company, this heater will provide full coverage in rooms up to 81m³. As well as a built-in thermostat, air flow can be altered using the included magnetic remote control or, if you prefer, via Dyson’s excellent app.

There’s no doubt the Dyson Hot+Cool is expensive, but for your spend you’re getting the best of three worlds: heating in the winter, cooling in the summer and arguably the best air filtration system in the business. Screwdriver found, and the screw undone and refitted, you then remove the base plate securing nut from the standing pole, thread the standing pole through the base plate, and refasten the securing nut. You don’t get many onboard controls on this sleek cylindrical ceramic heater; but, then again, it’s designed to work via an Apple or Android app, which lets you set your preferred room temperature and even set a schedule to turn it on and off over the course of a week. PORTABLE DESIGN – The lightweight design and 1.2m power cord are ideal if you need a heat source that can be moved around the home from room to room

This attractive Italian-designed model from DeLonghi arrives with a high-quality, cool-to-the-touch metal casing with legs attached. And with its maximum sound pressure of 48dB, it’s one of the quietest fan heaters you can buy. On average, the cooler’s internal temperature was 7.4ºC, although it hit a peak of 11.9ºC and a minimum of 4.4ºC. This temperature range is fine for cold drinks.
