dehumidifier versus panel heaters

The heat you get from a dehumidifier is the same as you would get from a small refrigerator with its door open.

Well I can set my dessicant dehumidifier to produce 350w, and various settings up to about 800w. I suppose if a small fridge produces 800w with its door open, it must be a very large small fridge.

Btw, there's no similarity in operation between a fridge and a dessicant dehumidifier, as you appear to think.

A dehumidifier has a cooling coil and a fan to draw the air over the coils.

The same components as a fridge.

The reason is that a dessicant one works by blowing warmed air over the dessicant material to evaporate the water (i.e. you put in the latent heat of evaporation to evaporate it!), then the warm moist air is cooled over a heat exchanger where the water condenses out (releasing the latent heat you've just put in).


Yes, that sounds about right to me, but there is an energy release that comes before the cycle you describe when the dessicant wheel initially absorbs the moisture.

So, you haven't googled 'dessicant dehumidifier' yet.

Not the same components as a fridge at all, and no similarities whatsoever.

The one I have has a coil and a fan.

So what? It's irrelevant to this discussion what you have.

Not sure what that means.

But you have incorrectly disputed several times how dessicant dehumidifiers work, and therefore misled the op who requested some guidance. No problem with people occasionally getting things incorrect (as I sometimes do), but it seems stange to me when it goes on over several (lazy) one-liner posts without any attempt to research the correct situation even after being pointed in the right direction.

From what the op says, i agree with others that some type of dehumidifier is likely to have advantages over a panel heater in his/her situation. If you have a cogent argument why it wouldn't, then I'm sure the op would appreciate that input too.
