Drying clothes with coal

I have attempted in the past - without displaying propitiatory data - that it takes nothing less that Hi Pressure steam to generate exchange temperatures successful for a clothes dryer. Simple residential boiler water is useless and it is far more economical simply to run your home dryer on the setting that only brings in fresh unheated air.

This is your simple reminder -- YOU can search for the rest

I think it would be more efficient to simply vent the clothes dryer inside the home during the winter months. I have done this since November and all I did was attach the dryer exhaust to a bucket partially filled with water, then vented out the top with a filter screen. The water collects the lint and I just clean it out every few weeks. The added heated moisture to the air is where the recapturing of wasted energy occurs.

I've pondered coal fired clothes drying, getting real hot air from 180 degree boiler water causes longer drying times from what I can tell.

If that unit works, maybe a stock electric dryer could be modified but I think the real solution may be in Europe, and that is painfull to say.

A clothes drying cabinet, less air to heat, and not quite as warm, with longer drying times. Support from the better half would be required.

These are electric but might be a start, the temperatures are lower so hot water might do it, and they should be darn near silent, just a fan.
And no lint just like line drying, vent inside the house without lint concerns.
Just a starting point, for sure, cost seams high. I'm not sure how to build a wood cabinet that would handle the high humidity but maybe start with a fiberglass shower and add some stainless racks, it just gets messy. Maybe wood cabinet with hull paint, I just don't like wood for this.
