Throw it out and buy a new one.

Okay I see what you're doing now....I was a little confused by your explanation.





condenser / heat exchanger ...more or less the same thing working in different ways ...not exactly. In this instance a heat exchanger is used to condense the moisture in the air, but a heat exchanger comes in many different forms and has many different functions.

For instance a radiator in an automobile is a fin and tube heat exchanger, used to reduce the temperature of the engine coolant..no condensing there. A shell and tube heat exchanger can be used to transfer heat from one liquid to another...no condensing there. The pulp and paper mill I am employed in has many different functions for heat exchangers. One being the condensor for our turbo-generator to condense the steam to increase pressure differential across the turbine, and another condensor on the output of our multiple effect evaporators to maintain a vacuum to aid/increase steam flow, both shell and tube heat exchangers.

So you see there are many forms and functions of heat exchangers, and I've just touched the tip.

what I meant was they were one and the same in the instance I was talking about ..nothing more

It pulls the moisture out of the warm dryer air. By cooling the air the moisture condenses and drops out. Without the moisture you can use the still warm air to heat your house. or garage.

so if you run cold water through that gas boiler heat exchanger ..then blow hot air from the dryer over it or through it externally ..water in the hot air will condense on it....

don't overdo it with the water flow ..or you wont get any saved heat back .

I am thinking of running the "hot" air from the dryer threw some tubes (Evan talked about using pop cans) and then pass the room air over these tubes. The insides of the tubes would collect condensation and need a way to drain off. I would think the then cooled and "dehumidified" air from the dryer after passing threw the tubes could be used as the source to blow across the tubes? Instead of a second fan or whatever blowing air across the heated tubes? Yes no?

That heat exchanger above. That I called a condenser ..works in cycles by the dryer taking cold air from inside the room ....so cooling it down ..then after a say 20 seconds blowing cold air through it, it blows the warm air from inside the drum over it ..

You could have a condenser as in the picture hung on the wall further up ..by running cold water through it. maybe using a gas boiler matrix as the condenser.

one of these things with cold water going through it

I've read your description over and over....at least a half dozen time and I'm still confused. One thing I do know is a condensor is used to change a gas to a liquid...but I'm ignoring that thought and just thinking heat exchanger.

That is very interesting! I remember Evan posting a heat exchanger he built for his dryer and I have been thinking of doing the same thing.

[aboard_epsilon]

My rear bearing is an oillite bush in a swivel housing ...not on its schedule or anything ..but every couple of years I have to service it ..or it locks into one position in its housing...then the drum locks! ....last time I used ptfe high melting point grease ..its been four years now and no trouble .



The condensing dryers have a container for the water and a removable lint filter . the container, when full, stops the dryer and puts a neon light on .the water container needs emptying every 2 - 3 cycles, the lint filter needs cleaning after every drying cycle.

it has a removable aluminium condenser that I have to remove and flush through every 20 or so drying cycles ...I flush it in the bath because there is enough room under the taps to get it in ..as it I measures about 16 x 12 x 4 inches

condenser part 146.
water container part 346

The chances are you will be inside there to repair it again in a couple months in the very least.

Everything comes from the same factory in China and has a different label slapped on it. My old dryer looked the same internally. On mine the value engineered for profit, rear bearing went out. That's a pretty simple and cheap part and I probably could make my own if I wanted. The problem is when the rear bearing goes out, the tub tips forward and both makes a hideous noise and destroys the complicated seals/bearing thing at the front of the tub. After replacing the back bearing the front seal will still grab and rip up clothes. Yup the tub is only supported at back hurray for value engineering. Anyway the front bearing/seal apparatus is like $100+ on a $300 discount dryer its not worth it and there's no way I could make an entire new injection molded front of the dryer.

Or the TLDR is while you're in there, replace the rear bearing before you get stuck having to replace the whole front of the dryer.

Heat in winter does get dumped in the house some. Great way to bring the humidity back up some.

[Doozer]

Me thinks you could wire up 3 or 4 red-eye
range cooktop elements in there and have
a more robust element system. I think
red-eye elements are like $8 at Home depot.
Might make a good retrofit and last longer.

At one time they were selling a dryer heat vent that sent the heat into the room and not outside.

The problem with them is that you are also dumping lots of water into the house, not to mention the lint that is not caught in the lint trap.

[kbertoson]

Did you get the dryer repaired and running again. At one time they were selling a dryer heat vent that sent the heat into the room and not outside.

Looks more robust than our European offerings we have here ..our heating elements are usually in a little tin box about 7 x 3 x 3, but very cheap to replace, can be had for under £10.
Knowing what I know, I would chuck the thing out and if available on your side ..buy a condensing dryer .

As these (in the winter) have a dual purpose ...all the waste heat will heat your house ..meaning you're not chucking the waste heat out of a hole in the wall.
edit ...having said all that, I see that there also European ones that are like a giant cooker hob solid element.
but as for my advice on condensing ones , I'm sure is this is the way to go . if you have expensive electricity in your parts ..UK price is about £0.15 pence per kwh..Most dryers have a 2.0 -2.5 kw heater in them ...so depending on the heat setting can cost up to £0.45 per hour to run with the motor adding to it.
