While today’s fan heaters are pretty energy-efficient, they’re not suitable for leaving on for hours on end; they still consume a lot of electricity compared to, say, standalone oil-filled heaters. In fact, most of the models in this guide will cost between 35p and 70p per hour to run, possibly more given the current high electricity prices. 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. 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.

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.There’s no thermostat on this model, since there’s no compressor. Instead, the mini-cooler uses a thermoelectric cooling system, which means that it just chills the inside to between 16ºC and 20ºC below the ambient temperature, although the lowest temperature that it can achieve is around 5ºC. 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. In both cases, Russell Hobbs recommends that you leave the cooler for four hours to achieve the right temperature before putting anything into it, so you’ll need to plan ahead. Performance The last thing to note is the Russell Hobbs 12” Scandi Desk Fan's size. Pictures make this appear a fairly compact design – perhaps because the grill is see-through rather than solid like the MeacoFan 1056 Air Circulator – but in practice this fan is really pretty large, especially so if it's going to be sitting on your desk next to you. You will definitely need a desk larger than mine. This was a little disappointing considering nearly every other fan I’d tested came ready assembled – and because I couldn’t find anywhere that warns that the product would need self-assembly on the box.

However, there aren't really that many settings to choose from, so once you've chosen your desired setting, I suppose it's likely you might just leave it running without much adjustment. Still, it would have been nice to have the controls on the fan base stand. When it comes to air purification, this Dyson can filter down to 0.1 microns, which includes pollen, pet dander, bacteria, smoke, benzene, nitrogen dioxide and, in the case of this specific model, formaldehyde – a poisonous gas emitted by cigarette smoke, many household products and wooden flooring. In other words, this model doesn’t just heat – or cool – the air in your room, it cleans it too at a rate of up to 290 litres per second. At 76.4cm in height, the Hot+Cool Formaldehyde is quite a lot shorter than Dyson’s standard tower fans. Nevertheless, it still enjoys the attractive design for which Dyson products are well known. 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. Aside from these minor design foibles, the Capsule Fit heater performs exceptionally well. It comes with two simple controls: a thermostat dial and another for its three heat settings (up to an impressive 2.4kW). The highest heat setting also increases the fan’s speed for extra reach.This product comes with a free one year manufacturer guarantee.
