Heated Clothes Rack vs Dehumidifier Electrical energy Managing Costs & Room Heating Efficiency of Desiccant Dehumidifiers

Sharing is caring!

Continuing my obsessive posting about the price-of-living disaster, I have been seeking into the advantages of employing a desiccant dehumidifier above a heated outfits rack for drying clothes.

Yesterday, I reviewed the Dry:Quickly 3-Tier Heated Airer. It is about the best-heated dresses airer/rack on the current market, but it is out of inventory, and I am not very as impressed with it as all the glowing evaluations you see online.

A prevalent suggestion for drying outfits is to use a desiccant dehumidifier and inserting it in a small room or working with a clothing rack which is lined up with a sheet.

Desiccant Dehumidifiers vs Compressor Dehumidifiers

Desiccant dehumidifiers use very a ton of electric power compared to compressor dehumidifiers this sort of as the Ebac 3850e. This is due to the fact they clear away h2o by organic absorption. They then use an electrical heater to continually regenerate the adsorbent material (dry it out).

There are some arguments from this style of dehumidifier. Simply because it will continuously extract humidity, it then attracts it in from outdoors, generating them inefficient to run. It is claimed that they will take away all around 3 periods more moisture than is expected for an average British home with 4 occupants.

Nonetheless, in this circumstance, they must operate effectively.

Pros of a Desiccant Dehumidifiers vs Heated Dresses Airer / Rack

A desiccant dehumidifier will extract h2o from the air and expel heat when it regenerates the adsorbent materials. They can expel very a lot of warmth, so when utilized in a modest home or under a lined rack, they can heat the bordering air fairly a ton. The quantity of warmth the desiccant dehumidifier is why it is advantageous more than a compressor for clothes drying and home warming.

This heat, reduced, humidity air really should, in concept, dry your outfits very promptly.

The further reward is that it will lessen the humidity in your house much too. Whereas a clothing rack will increase the humidity. High humidity in a cold climate can lead to condensation and mould complications.

Heating Effectiveness of Desiccant Dehumidifiers

One particular of the attention-grabbing issues about desiccant dehumidifiers is that they are very successful as a heater. With a COP (Coefficient Of Overall performance) of close to 1.25-1.5 they are not as efficient in contrast to a dedicated air supply heat pump, which may have a COP rating of 2.5-4. But they are far more productive than electrical heaters, which have a COP of 1. In essence, an oil radiator will give off 1kW of heat for 1kW of electricity.

Working with a desiccant dehumidifier in a room for heating isn’t an suitable remedy. You never want to convey the humidity down also lower, and they will typically shut off at a specific humidity.

Drying apparel in a home to insert humidity also decreases heating performance simply because it will attract warmth from the air to evaporate dampness from the outfits.

Even so, they can be utilised to complement current heating while also staying extremely economical at heating a area and drying garments.

Heated Apparel Rack vs Dehumidifier Energy Running Expenditures & Functionality

At last, having all around to how well the desiccant dehumidifier performs versus my Dry:Shortly heated airer.

Carrying out a like-for-like take a look at has been tricky, and I need to have additional time to use them both in different scenarios. I have also positioned my Airthings View As well as in the exact area, so I can get a superior plan over the upcoming couple of months of how a great deal big difference each strategies make on the overall place setting.

A single of the challenges I have is that heated dresses racks have so-so overall performance. All the item photos your see has men and women draping the apparel around the heated pipes. With Dry:Shortly, I have the equipped address, which is intended to increase overall performance by making it possible for the air close to the dresses to heat. In truth, I discovered it was not a perfect resolution, and you genuinely need to be rotating your clothing to dry them successfully and speedily. You can lay them flat on the rack, which substantially raises drying time but lowers potential.

For the Dry:Before long, this meant that drying periods could be wherever amongst 4 and 10 several hours relying on how I put the dresses on the rack and how considerably I fiddled with them.

The Dry:Shortly employs extra than the quoted 300W. I calculated it was closer to 348W about a 4-hour period.

The dehumidifier I utilized was the EcoAir DD1 which I acquired 5 many years ago for £130. It is nevertheless on Amazon, and you can acquire it for £150. I then used this sat below the Dry:Soon rack with the fitted cover shut. It was found in our front space, which is very large. Drying functionality will probable be enhanced by transferring it to a boxed area, but I could not be bothered with the faff, and I required to gain from the heating outcome it would have on that place.

The dehumidifier with its location dialled up to max attracts 668W, and this will auto shut off when the water reservoir is total, or the humidity drops very low sufficient.

In my first take a look at, I ran the dehumidifier with a whole rack of outfits until it made use of 1.5 kWh of energy. In this scenario, the clothes ended up even now damp, whereas the Dry:Quickly a lot more or fewer dried my outfits when put flat on the rack.

Switching it on once more and continuing it to run for a further 1.5 kWh of electricity, it had dried nearly all the products. I had also positioned some lesser garments objects on the cold radiators in the very same place, which were almost fully dry.

Moreover, I monitored the temperature in the room for the additional pair of hours it ran, and the home warmed up by 1°C heading from 17.4°C to 18.4°C.

The subsequent working day I employed the Dry:Soon. Dresses have been a mix of laid down flat, and it took 8 hours for the the vast majority of them to dry, a couple bits were being nonetheless a little bit damp. Humidity grew to become a authentic challenge, hitting 81% when I switched it off and with condensation on the home windows.

Temperature also greater very a little bit, but I assume this is partly due to everything warming up concerning 5 am and 12 pm.

In my third take a look at, I ran the dehumidifier for 5.7 hours working with 3.71kWh of electrical power. This is about 1kWh far more than the Dry:Shortly exam I did the working day in advance of.

In this take a look at, the clothing were being dry, and the humidity in the area was significantly minimized. The temperature failed to go up as considerably as expected, but I feel that is for the reason that the external temperature is rather a little bit cooler currently (the working day prior started off awesome, but the afternoon before long was incredibly hot).


I will carry on to do additional tests to test and form a more accurate viewpoint on overall performance.

Both alternatives do the job nicely. Heated dresses racks are well founded as being a beneficial expense-successful option for drying clothes in the wintertime months.

My major intention of this submit was to see desiccant dehumidifier could give a similar level of general performance. My preliminary impact is that, factoring in all the variables, certainly, it would.

Even though it didn’t dry as promptly and did use far more electrical energy vs laying dresses flat on the heated rack, it did dry a much larger number of clothing, reduced humidity and warmed the room.

Contemplating that heated clothing racks have sold out at most places, I would suggest that a dehumidifier is an exceptional alternative.
