PSA: The condensate from your dryer is distilled water (slrpnk.net)

It's the first time I own a dryer. When I poured out the water it has collected (a few liters per run) I quickly tested the EC and pH and found out, that it is almost identical to the one made by my reverse osmosis filter!
No wonder, since the dryer is basically just a big distillation machine.

Thats super neat. It will save me a lot of work filtering tap water.

I will collect it from now on and use it for watering my plants.

Why does it matter?

Plants really don't like tap water. Even in a country like mine, where no chlorine/ fluoride/ whatever is added, the dissolved minerals cause trouble. They will build up over time and make nutrients unavailable, even if you adjust the pH.

The buildup and nutrient lockout will harm the plants a lot in the long term, and you will have way more trouble checking and correcting EC and pH.

Yeah no, it has to be on 2x as long everytime I use it. I don't give a shit if it uses more energy if that means I can spend 3 hours doing laundry and not 6.

Any savings are lost when the machine has to be on and working for twice as long

    1. That makes no sense because if it's on for twice as long but uses less than half the watts then it doesn't lose any savings does it.

    2. You sit and watch the machine when it's on? Do you do the same thing with your dishwasher? Mine takes 5 hours but if it took 20 it literally wouldn't be an issue

    Heat pump driers use a bit of electricity to get up to temperature then a tiny amount to run the compressor and keep the heat topped up thought the cycle, they can take longer for some fibres (ones they have high resistance to airflow and also like to hold on to water) but they use far less energy to do that. The amount of energy used is not consistent through the wash.

    Some loads my machine takes just over 1kWh (25p) to dry, maybe 2.5 hours, other loads take 30mins and 0.3kWh. (~8p)

    If this is supposed to be some kind of contradiction to me saying watts, then obviously you need to integrate it over time and arrive at the total used. It was just an example of how something could take longer but use less in total, not a detailed description of how a drier works. But thanks anyway

    My electricity bill is much higher because I have to do multiple loads that used to be able to do in one. I don't care if the machine is technically more efficient if it takes a considerable amount more time to do the same amount of laundry. (My electricity is generated by hydro electric and without oil and gas and coal so efficiency isn't a big concern of mine.)

    A task that should take 2.5 hours takes over 5 hours. It's not at all like a dishwasher and you can damn well understand if your dishwasher sucked so bad you had to do multiple loads it isn't as simple as starting it and forgetting it. Also you never have to unload your dishwasher each load to put them into a dish dryer, so that's an incredibly shitty and useless comparison. Nor do your dishes need to be folded for that matter.

    I do other chores when I'm waiting between loads like a normal person. What the hell are you trying to say?
