This varies according to the design, size and extraction rate. Generally speaking, desiccant dehumidifiers use more energy per hour than a compressor model, but can also work more effectively at removing moisture, which means costs tend to even out.

Look for one which draws less than 330 Watts and you will never spend more than 10p per hour. It’s often much less on lower power settings. Dehumidifiers are generally cheap to run. What size dehumidifier do I need? All dehumidifiers do the same basic job of removing excess moisture from the air. However, there are three different technologies that do all the hard work. CONVENIENT & EASY TO USE: With a large removable 6.5 Litre water tank or the continuous drainage feature to remove up to 20 Litres of moisture today, this dehumidifier will suit everyone's needs. With a two-litre tank, it might need emptying more regularly than some models, but there’s a 1m hose if you need continuous draining into a sink or drain. And while there’s no timer, you do get a laundry mode and a choice of quiet and turbo functions, and the rotary control is – as advertised – simple and easy to use. However, it’s worth looking out for newer and more energy-efficient designs. For example, Meaco’s MeacoDry Arete One 20L costs around 6p per hour to run, based on an electricity rate of 28.3p per kWh, while some models will cost significantly more at the same rate. Use your dehumidifier daily for a couple of hours and the difference soon mounts up.HIGH EFFICIENCY & LOW ENERGY CONSUMPTION: Squeezes Up to 250ml of water a day from Humid Air.

Compressors are generally efficient at room temperature, but they can’t handle the winter cold so well. If the temperature drops below three or four centigrade, they will tend to stop working. That’s not the case with desiccants, although they can be more expensive to run. How to use a dehumidifier PORTABLE & EASY TO STORE: Portable & Easy to move with casters and Lightweight compressor Four castor wheels are conveniently located on the underside of the dehumidifier to allow for easy moving without having to lift the unit each time.

Key specs – Dehumidifier type: Desiccant; Tank size: 2l; Extraction rate: 6 litres per day; Dimensions: 48.5 x 29 x 17.5cm; Weight: 6kg; Warranty: 2 years If you’re only planning to dehumidify occasionally – for a few hours here or there in a kitchen or bathroom, for instance – you can get away with a mini-dehumidifier with an extraction rate of less than one litre. It will be cheap to buy, cheap to run and perfectly effective. The same applies if you’re trying to fight damp or mould in a smaller area, such as a wardrobe, utility room or box bedroom. It’s simply a matter of setting the desired humidity level and the unit will do the rest. What you will need to do is empty the water tank from time to time. Where should you place a dehumidifier? It all depends on how much space you need to dehumidify. Dehumidifiers are often rated in terms of their extraction rate: how much water they can remove from the air in a single day. This is separate from their water tank capacity, which covers how much water they can store before you need to empty them out.

What are the best deals on dehumidifiers?

If you’ve ever had reason to ask yourself ‘what is the best dehumidifier?’ it was probably with a sense of desperation over mould in your bathroom that just won’t shift, or window condensation forever puddling on the sills.

These can be easily fitted or removed according to preference. If you’re pulling out 15 to 20 litres per day, the dehumidifier needs to have a tank with the capacity to handle it or you will be emptying it out every few hours. Three litres is the absolute minimum, while five or six litres will give you a bit less emptying to do. Is there anything else worth looking out for? Dehumidifiers don’t have to be noisy, and there are some good near-silent options.

So keep the interior doors open and the exterior windows shut.” How much does a dehumidifier cost to run? Don’t get too excited about any claims of silent running – we found that, while actively dehumidifying, it puts out around 50dB on all of its three settings, so you won’t want to sit and watch the TV while it’s on.

And at 9kg it’s light enough to take from room to room, making this a great dehumidifier for the average flat or small to medium-sized home.
