5.0 out of 5 stars Excellent value, stylish, compressor-driven dehumidifier, 30 Nov. 2013
This review is from: ELA RD12D Digital Dehumidifier up to 12L/day extraction
For a compressor driven dehumidifier, this ELA RD12D is fabulous. It is very similar to the manually-controlled models carrying the Dimplex and Honeywell names, but with improved moisture-extraction performance and digital controls, at roughly the same power consumption and price. Bargain!

This RD12D weighs a very reasonable 10½kg, and at 49cm(H) x 37cm(W) x 22cm(D) it's very stable yet still easily movable from room to room. The quality of the plastics and tactile nature of the front-mounted light-touch membrane digital controls give this unit an air of robust quality. It certainly feels as if you've got your monies worth!

It has a generous set of features too: You can pre-set the humidity level to 50%, 60%, 70%, 80%, Continuous operation or Automatic (where the unit will self-adjust humidity level based on temperature). In use, the display always shows current humidity (it's accurate enough when measured against a professional meter), and the fan can be set to either high or low speed; at low speed, even with the compressor running this is a remarkably quiet machine given it's impressive 12 litres a day maximum extraction rate (although actual performance depends upon room temperature and the actual moisture content present in the atmosphere).

There's a timer too; you can pre-set the unit to run for up to 24 hours in 1hr increments (rather than the 12hrs maximum it states in the manual) before shutting off. Best of all though, the fan shuts down completely once the humidity level has been reached - a feature which is very unusual for a machine with digital controls. In this state, it uses just 2w of power. The fan will quietly re-start periodically just to sample the air (14w at low fan speed, 20w at high), deciding then if to re-start or sleep once again. This is good news for the energy conscious and those who prefer a generally quieter environment, and gives confidence to those that don't want to waste money yet intend to let this dehumidifier run for longer periods to alleviate general damp, condensation and mould problems.

What is particularly impressive is the energy efficiency for a machine with this much moisture extraction potential; it states 260w maximum power consumption, but in reality it measures a paltry 148w at low fan speed with the compressor running - that's a maximum cost of roughly 2½p an hour at current electricity costs, remembering of course that for much of the time it's only monitoring air at 2w consumption. On average then, this is a remarkably cheap unit to run. It has to be said though - in common with all compressor driven dehumidifiers where the maximum extraction rate is gauged at 30c @ 80%RH - that is a somewhat ambitious/ unrealistic measurement criteria in our cooler British climate! Never-the-less, moisture extraction rate in real-world environments is good, and equal to/better than many other dehumidifiers I own: It dried a full-load of washing in an enclosed room in just a few hours, and cleared a steamy shower room exceeding 99%RH in no time at all. It comfortably maintains a less-than-ideally insulated 3-bed detached house heated to 18c at 50%RH when placed on an upstairs landing - that equates to a dry, pleasant, more easily heated home that's free of damp, condensation and mould problems. When run continuously it managed to achieve a constant 37%RH! That's a little too dry for daily living, but a very impressive achievement for such a compact compressor unit.

There's a removable/washable/re-usable air filter, and an automatic defrost function when used for extended periods at lower temperatures intended to keep the machine operating optimally. There's a 2.3 litre bucket for catching condensate, and the ability to connect a hose (not included) direct to a drain if preferred. Once the condensate bucket is full the machine automatically shuts down, indicated with an LED on the front panel. However, with the bucket being all white plastic with no transparent panel, you cannot visibly tell when the bucket might be approaching full without physical removal; removal will automatically shut the dehumidifier down until the bucket is reinserted. It's a minor annoyance, and the only criticism I can personally level.

Other than that, a first-grade good looking compressor dehumidifier that's as cheap-as-chips to run, and exceeds all expectations at this price point. It's one I'd heartily recommend for those looking to reduce moisture in warmer home environments - and of all the dehumidifiers I own, this is the one I leave running permanently in my own home. For those looking for a domestic dehumidifier to work efficiently and effectively at sub-15c temperatures though, check also ELA's DD822 Dessicant Dehumidifier.
