One of my Hotpoint workshop dehumidifiers appears to have just died - at just
the time when I've also using the conservatory for extra space, so will really
need another one too.
It's running, but getting warm rather than cold, so I suspect a terminal
degassing in some unfixable manner.
Any suggestions for favoured models to replace it? I'm looking for reliability
over a good few years, more than a quick bargain.
I got 3 from homebase, probably almost 10 years ago, which get trundled
around the family when someone needs one. They were 75% off in a store
which was closing down. They are New Widetech Industries Co., Ltd, who
I think mostly make OEM models for other people. Mine happen to look
exactly like an Ebac model, but this model is obsolete now. The rating
plate says 400W, but they actually draw 250W (although the compressor
switch-on surge can blow 5A fuses).
All 3 get lots of use (in clothes drying cupboards, mainly). One of them
had an early failure on the simple control circuit board - a zener diode
failed, which I chose to fix myself rather than go through the warranty.
The other issue is that the defrost cycle is not very good about kicking
in soon enough, and when operating below about 13C, they can end up with
the evaporator encased in a solid block of ice, and once this happens,
the defrost cycle can't thaw it out. I worked around this with one of
them which operates in colder conditions so that if the temperature is
below 15C, it switches off for 5 seconds every 30 minutes, as whenever
it starts up, it runs a defrost cycle for the first 3 minutes anyway,
and this is enough to keep it from forming a solid block of ice. Max
ambient operating temperature is 30C, and in a drying cupboard you can
manage this by plugging in via a thermostat which cuts off above 30C.
These have water tanks, but can be plumed-in instead - something you
might want to consider.
