Condenser laundry dryer pump

  • This video is partly about a special purpose pump, but also explains how a very common European unvented tumble dryer works. They're extremely efficient and require no external exhaust vent.
    The simplicity of the design is stellar, with one main motor for drum rotation and the hot and cold air-path fans. The fans are the centrifugal type, so even when the machine changes drum direction briefly, the fans still push air around.
    The water extracted from the clothing is pumped up to a pull-out reservoir which can then be poured into a sink. Alternatively, some of these machines can be plumbed directly to a drain.
    By recycling the hot air in a loop, these machines have high efficiency, and also contribute to heating your home in winter. Unfortunately they also heat your home in summer, which isn't so good.
    They also do leak a small amount of fine lint which adds to the usual dust issue in homes, but most of the lint is caught in a small lint trap that is cleaned before each cycle.
    Because we have very high power available at all sockets in a UK home (32A 240V power circuits) we can plug these machines into any socket in the home. It's common to have the laundry equipment in the kitchen, but the dryer could be put in any spare room in the house.

    This also keeps the channel independent of RUclips's algorithm quirks, allowing it to be a bit more dangerous and naughty.

    This is practically very similar to those little fish tank pumps that circulate water. All washing machines use this type of pump. I remember our first washing machine. It was a Czechoslovakian TATRAMAT brand an when it finally gave up the ghost in the late 1990s I dismantled it and took the pump because it was working just fine. It was strong enough with enough pressure to serve as a garden pump for filling our water barrels.

    Interesting to see this broken down like this. We have a very similar machine but the water collection tray is at the bottom (identical condenser section), as a result there is no pump but yours would have the advantage that you COULD feed the output into a drain and avoid having to empty it. To do the same on ours your drain would need to be below the floor level.

    Great machines when the weather's to cold & wet for the washing line. For best use, empty water tank & clean lint catcher in door after EVERY session, pull out & clean the condenser every few sessions & most of all, use in a cool well ventilated room. This last point improves the efficiency of the condenser, reducing running times & saving energy as well.
    Also, as Clive points out (if you are confident in doing so) remove the back cover too & check & clean the heating element, incase of lint build up.
    Had my Hotpoint nearly 20 years now & all that's failed is a heating element/ thermostat part( which was easy & cheap to replace).

    We have a similar pump on our central air conditioner in the US.

When I took our old one apart to unclog it once, it was a similar arrangement, but the impeller had 3 wings, and the motor operated by float switch in a small reservoir.

    I suspect the rubber impeller is such that the vanes can sweep in the right direction, because single phase synchronous motors spin in a random direction when they start, don't they? Interesting choice to do it that way, instead of going for a shaded pole motor. I imagine the price difference is very small but it's still probably the reason.

    This is almost exactly the same dryer that I got, mine has a different "brand name" and also it has a lcd display, where you select programs. As mine is next to a sink, I just drop the outlet hose from the pump into the sink, so I don't need to empty the water container. A couple of years ago, it stopped pumping out water. Opened it up, and the rubber impeller in the pump had cracked open at the motor shaft, so no pumping was happening. I just replaced it with two zip-ties, and it has run happily ever since.
    Also, I think mine don't run the pump continuously.

    It should be pointed out that a condenser dryer and a heat pump dryer are two different animals. The condenser dryer still uses an electrical resistance element to provide heat. The heat pump dryer uses a compressor and refrigerant to provide heat. Condenser dryers are inefficient and are often less efficient than a regular "blow steamy hot air into the room" dryer. Heat pump dryers are on the other hand quite efficient. Mine runs at about a third of the energy as the old dryer.
    Incidentally even most heat pump dryers could be improved with an additional fan. You need a large airflow around the clothes, but the heat exchangers would work more efficiently if there were a slower loop of air. So the system should pass air around the clothes and then another fan bleeds off some of that air to pass it through the heat exchangers.

    Yes, we had a condensor dryer fitted in our previous house as we were unable to route a damp air vent outside for a regular dryer. Ours was a Bosch/Siemens. The pump sat in the reservoir and contained a float (ball in a tube) that acted on a switch. It would only switch the pump on when the level in the reservoir reached a certain level. The problem was that the reservoir would gradually get damp lint in that would stick to the ball causing it to stick, and the dryer would throw an error. I think that was time based - if it didn't sense the pump switching on after a set amount of time it would cut out rather than overfill the reservoir. Long story short, every couple of years I had to take the pump out to service it.

    We bought one of these condenser machines a few years ago (probably 8 at this point?), and me and my brother chose it back then as a gift to my mom specifically because it did not need a vent and instead just collected water in that comically long drawer reservoir, and I've always wondered exactly how it works. Turns out it really is stupid simple! I thought there would be something more complicated because of that strange "pump" noise, which for some reason I never really associated with _being_ an actual pump similar to washers!
    I've had to take a screwdriver to it once because water was condensing in the wrong place and tripping the breaker (the heater lol), but I didn't get an opportunity to explore it further. Besides that, it has been incredibly reliable, and yes, as soon as you pulled up that picture of the machine and said they all look the same, I can confirm that it looks exactly like ours.

      Isn't the reason for shutting off heat but keeping the fan running to prevent fires?
      Very hot, slightly damp clothes in a dense pile can sometimes auto ignite if they're left to sit like that. The manual for our dryer warns to always spread the clothes out so they can cool off quickly, if for whatever reason the dryer gets stopped while hot. The drying cycle always ends with a few minutes of cool air tumbling.
      To my understanding, what can happen is that some fabrics can begin to oxidise in a slightly exothermic reaction if the heat and humidity is just right, and if they're left undisturbed in a dense pile inside the tumbler then the heat cannot escape so the reaction slowly accelerates as the temperature increases until it starts burning. Same thing can happen in damp haystacks, where the initial heat comes from biological decomposition.

We have option of Bosch I think whirlpool and I can't remember the other brand but they're pretty much the European brands trying to hit the US market. We got one probably five years ago and it's kind of nice not putting all that heat out to the outside. Although I still think a gas dryer nothing beats it. What's nice is we got the washer as well and stacked them and then the washing machine just plugs into the 240 outlet on the back of the dryer which plugs in the 240 outlet on the wall. so one socket! I should probably say that the model we got has a hose off the back so no tank. It works reasonably well although occasionally the drain will get clogged up and then you put your laundry on and you come back and hour later to find that it errored out on a clogged drain.

    My Beko condensing dryer cycles the pump on and off as required, but it's a more fancy (things to go wrong) electronically controlled one.
    Also the evaporator delaminated slightly inside, resulting in some of the collected water flowing out of the tray it slides on to and ending up in the floor under the machine. "Fixed" by dremmeling out a notch at the back of that tray and adjusting the front feet to tilt the machine back slightly, so that the escaping water goes to the sump at the back where it would have originally.
    The part cut out is a lip for the seal of the condenser to mate against, without that it would have been a straight path from that tray to the sump.
    A new condenser on its own was around a third of the cost of the machine at the time and it was only three or so years old. Around two years later and it's still running ok.

      Hi Clive, I have the same model as shown. We had a safety modification done where lint could build up around the heating element. This involved fitting a brush arm to the rear of the drum which sweeps lint from accumulating preventing a fire. It was a manufactures recall mod and it works fine. I did have to replace the heating element due to the sump blocking up at the rear causing the rear fan blades slashing water onto the element so shorting it. I would suggest checking the sump drain hole to the rear tank every now and again so this does not happen again. Great video as always.

    My washer/dryer works slightly differently. There's a condenser that fills with cold water from the mains supply and the hot moist air from the drum blows across it. Condensate and the water from the condenser when it starts to warm up a bit just flow into the system that pumps the water from the drum at the end of the wash cycle. There are some sensors that measure the amount of condensate produced so the autodry program knows when the clothes are dry and shuts the machine down.

    Kind of… except the whole principle of these dryers is “condensation”, so essentially the colder the environment they’re operated in (ie. outdoor laundry) the better they perform!
    They still have obvious benefits come less humidity in a space, but the efficiency of drying is dictated by the difference between operating temp and ambient temp… hence the “condenser” effect.
    Although they still work fine for most households, especially when in comes to minimising humidity, they are particularly suited to the likes of wet rooms/mud rooms of European households. Using one a condenser dryer in moderate temp climates is actually less efficient than a normal dryer.

      My routine maintenance is to clean the lint from the heater air path and the sump.

    Particularly useful in winter because the heat input is not wasted but recycled into the room.

    They really dont sell much of this design in the US, they just call them ductless and are generally regarded as kind of bad. What we are seeing now are all in one washers and dryers using heat pumps for heating the air and then the cold side condenses the water out. Really slow, like takes 6hrs for a load but very efficient.

    Reminds me of the thing that they slap on the AC unit that cools the house. "AC Condensate Pump" is a good search term for them.

    We stayed at an AirBnB that had one of these washer/dryer units. It didn't work worth a damn. We ran the dryer for several hours and our 4 pair of jeans were still very wet. We finally just laid them out on the coffee table in the living room overnight and they were dry enough by the next morning.

      A common failure in the horrible washer/dryers is the condensate water valve. It results in the clothing just getting steamy and hot without drying.

    I would not have guessed that such a simple pump could move water up by about 30 inches. That pump is really reduced to its minimum number of simple components, but in way that considers the likely failure mode. We just switched to a heat pump condensing dyer in a US condo and it does seem to be more efficient.

    This all reminds me of the dryer that we had during my childhood and which was our only condenser dryer so far.
    I remember hearing the water pump activating after a while from the start of the cycle, presumably because of the float switch inside the sump.
    This dryer had a fan inlet on the back and the condenser on the front, which actually expelled (relatively) dry hot air.
    Also the condenser was crumbling to pieces and everytime my parents took it off to clean it there were pieces of hardened glue falling off of it, that had been previously put in it in an attempt to fix it.
    Nevertheless it worked quite well until The Great Fire of 2012 where it totally disappeared never to be found again.
    Now in my current house the dryer is of the vent type but I'm due to move out and might not be able to pipe a dryer exhaust oustide since I'll probably move to a rental flat.
    So I'll have to get either a condensing or heat pump dryer, however I'm not really sure what to choose.
    Any idea about the best choice ?

      Not sure the best choice these days. I've been happy enough with my indesit machine.
