Cost of running a dehumidifier

I don't think they run constantly, I think they modulate there use. But a 300w dehumidifier running 12 hours a day, on the average standard rate tariff (14.3p/kWh) it's 51.48p.

I think you would only need to run it for a few hours per day. Do you have ventilation strips on all the windows? They might not be effective but open them all. Keep kitchen and bathroom doors closed when using those rooms. Look at cleaning out your extractor fans in bathrooms or replace them. Open windows when having bath/shower, keep window open and door closed for a while after too.

You could start with airing the house with heating off for a day, open windows front and back to create a current through the house. Afterwards give plenty of ventilation once the ch goes back on.

Have you had cwi recently or is it a solid brick wall house or have you covered up any air vents, say with a new patio or rendering?

Hi, I suffer with condensation badly, always have, bought ebac 2 years ago, dec. ran it all the time, as you should, it,s got an inbuilt humdstat and it will work flat out until humidity drops, then it modulates itself after that.
All windows MUst be kept closed.
Cost approx 3p per hour
It cost me about £2.50 pw throughout the winter, 24/7 till april, still got condensation, but less.
This year leaving it off, too dear. just leave several windows on the nightlatch, locked overnight, windows clear next morning.
I,ve got a smart meter that tells you what each appliance uses, free off mse.
As soon as temp outside gets to approx 4>5 degrees. all my windows start to condense up.
Loads of air bricks, extractor fans etc.
Just one of those houses, my other was the same.It,s a pain.but incurable.
PS;As I,m typing this, 16.14 the temp outside is dropping and my windows are starting to steam-up from the bottom.

I've just had a week of leaving it switched off due to the running costs. Now I know for sure that it's worth every penny. I switched it back on yesterday after realising my house had become damp and difficult to heat. All my bath towels were still wet a couple of hours after use (that never happens with a dehumidifier). And even though the room thermostat was telling me the room was the usual temperature I felt chilly.

It depends on the size of your house;;and shape;;;bungalow;;;;;outside temps;;etc, There,s no set yes/no answer, just what ever,s best for you.
My house is dormer bungalow, z shaped, long, big, high ceilings, and condenses up all the time, and you need all doors open, and windows shut, to benefit fully from any dehumidifier, on 24/7.
horses for courses, glad yours suits you, for me, opening windows at night, although cool, keeps condensation at bay, which is my problem.
I would need 4 to benefit really, but at a cost.
Don,t put wet towels on rads, that,s asking for trouble.unless it,s bathroom, then, you don,t normally dehumid the bathroom, keep window open, if possible.
common sense really.
