Big commercial laundromat air to air heat exchangers post 7 to 15% efficiency gains depending on fuel and ambient temperatures... Electrolux of Europe has some online documentation if you want to google it.

The 'new' tech drier hydronics is just better control of a heat source to evenly heat a normal forced air clothes dryer system. You can bet there is a 'smart' motor spinning the drum & the forced air exhaust may be variable to better ramp up temperature of wet clothes to where it will shed moisture faster. The fact they are offering retrofit options they promise to install in thirty-minutes should warn us of something, just not clear as to what!

hokeysmokes - their website has terms and conditions as the default page!

I probably violated umpteen of their provisions talking about it before you voloate them by going to the page to see where we are getting sued from!

Their 'terms' fail to provide a scroll bar in both firefox and internet explorer, selecting all and pasting into another document will yield six and one-half pages of legalese...

Let's all go out with a good solution in search of a problem in their honor!

I don't understand how they rate them.
Some must claim '7 to 15% efficiency gains' (I believe you), some claim to 'increase efficiency 25%', others claim 'heat-transfer efficiency of 98%' (link).
Swinging from 7 to 98%?

I figure a lot of it is based on cost.  When gas was cheap, it wouldn't make much sense to spend $500 on a ulta efficient heat exchanger for a consumer drier.  It would have made sense to spend $10 for 15%.

Now it might make sense to use a 100W compressor heat pump exchanger.
I expect it would retail under $100, mass produced.  Smaller, lighter, but not a lot different parts than the $89 dorm fridges.
