I've always wanted to explore one of the classic American Peet boot dryers, but they never seemed to do a version for 220-240V countries.
While having a random browse for similar items I came across a single eBay listing for just one item and bought it to explore. The box came in a brown paper Amazon bag, but when I searched for the item it was shown as not being available.
It's interesting that this unit claims to be "the original". So which came first? The American-made Peet unit or this one?
The Peet-style units are quite neat in that they rely purely on warm air convection to warm boots or shoes and carry the humid air out. As such they are silent, but much slower than forced air versions. However, this also has the advantage of not overheating the footwear and damaging it.
The heater assembly is refreshingly simple with most of the structure being an aluminium shroud to protect the plastic pipes from heat damage. At the base a metal pin passes through holes in the aluminium shroud and then goes into a groove at each side and is locked in place by fins on the plastic cover. I'd guess that the heater assembly and plastic boot supports have evolved with time.

This thing is so big it doesn't even fit in my large filming area. It's the closest I can find locally in the UK to what Americans would call a peat boot dryer. P-e-e-t boot dryer. And the idea is that you place your boots on these stems at the top and it tilts them back so the toes points of upwards like that and it drizzles without any noise. It just drills a bit of heat up these tubes. Look at the flare out there, that's the pearl of black on black filming. but there's heaters in here and the heat rises up and it goes into the boots and it gradually just drives the moisture out. It's not a fast thing, but it's the sort of thing if you leave it on overnight. it should hopefully dry your boots ready for the morning. I've not clipped the base onto this yet because I don't want to clip it on because well, we're taking this small bit. It all comes to bits. We're taking this bit back to the bench so we can take a look inside it. So uh, back to the bench. We go one moment please. and now we're back at the normal bench where this still doesn't quite manage to fit in. It is a big thing. let's take it apart. Audrey This came. it was, uh, what brand was it? Let me just double check that it was at job site boot drawer. It's the only one I've ever come across. Uh, it comes an adapter for Europe and it's got the British plug on it and the power consumption is 40. Watts So 20 watts per heater in each of these tubes. Let's see if we can get the base off here and take a look inside and see what they're using as heaters. Although from the top looking down, it does look suspiciously as though they're using standard ceramic resistors. So maybe there's going to be some inspiration for cobbling something together out of random bits of plastic pipe. If you get stuck in a situation with wet boots that you kind of want dried out, so is this going to come off? Is this going to come off? No, it's not going to come up. Is it clipped on as well? Oh, there's a Oh, there's a hidden screw. The Bastards. There's a hidden screw. I've just punched the screwdriver through the level and here it is. That's the warranty button there. Not to worry, there's really not much to go wrong with this. This screw is also not really one to come out there. It is. it's out. now. What do we have? We have the incoming Supply live is broken via the switch and then goes out to these heater pillars which look very similar to the American one, which is not really surprising because it's probably a copy. So this is this going to come out? It's kind of sticking. I may have to plasma and Charlie while I Take this off camera because this is a knot easy. it's coming down to a certain degree and then it's kind of stopping. And I don't think it's the cables that are actually stopping it. here. it's oh no no, it's just come out on cue. I Think it's just the stickiness of the metal. Oh look, it's a ceramic resistor down. There is ceramic resistor with ceramic spacers that they've put this little stud through this little t-shaped bit through. They've got a ceramic bead the other side and then they fed the resistor leads through. Can I Get this more open Can I Get it more opener. There's that little ratchety clip thing I Don't know if they folded this around I Think they have folded this around. Bear with me one moment while I Try and get this open. Now here's the completely wrong type of screwdriver to do this: Cisco Reveal more. It's going to reveal resistors marked 25 watt, 700 ohm. so it's 225 Watts 700 ohm Resistors in the series by look of it and it's quite nice. The most important thing here is they've got them in this aluminum Shield that is basically stopping them from touching the plastic so the heat can rise through. this and the radiated heat isn't going to actually cause an issue with the plastic. That's very straightforward. That is about as simple as you could get, which is nice. I Pondered how they were doing I Thought it might be something more sophisticated. Apparently it's not. and the way these are held in, they're basically they've got these little fins sticking out, just not supposed to stick out as well I Think it is to actually keep it spaced from the pipe and then at the bottom, they're simply holding that in with a metal pin sat in to a ledge that stops that dropping back out again and that is presumably being held in by. Well it is. It's being held in by these little plastic bits that push against the middle of the pin. Well, there's not much to that is there. so that's fundamentally it. All that's in these devices and why wouldn't that come out is resistors to create heat? I Mean that basically speaking, uh, heating element is a resistor. Um, again, they've kind of like they've folded out to the tabs here, but oh, they've got little round ones here just to space away from the case. I Don't know. bend that down really helps or not I've just done it anyway. but the same again that resistor and then just stuffed up the tube again. Very neat. Not really much to go wrong with that is there. and if you had one of these and it failed, which I extremely doubt it would feel because, well, those resistors are pretty indestructible. If it failed, you could possibly just get another 700 Ohm resistor or whatever it is in your country in America It'll be a lower value to get the same power dissipation. I Shall leave notes about that in the description down below, but that's fundamentally it. You plug it in and it just runs all the time. The heat goes up these tubes and goes into your boots. The boots are tilted back so the heat goes up to the toe and then carries the moisture back down as it cools and takes out the boot while drying it in the process. And that is it. Quite a neat thing.

    Good god ! Do these things actually exist Clive ? I give up if you can't deal with wet feet then you should not be working outdoors .imagine turning up on site with one off those bad boys tucked under your arm ???? Oh the disgrace 😭

    couple of 12v 21 watt indicator bulbs in ally tubes, & a battery charger, stick em in series for (low).

    job done:)

    Nice simple design.

    Since the space shuttle program has stopped it is great to see that NASA is also developing other stuff.

    I cobbled together some pvc pipes, a hairdryer so I could suspend my drysuit from a rail and dry out the boots.

  6. Avataaar/Circle Created with python_avatars ChompChompNomNom says:

    No one heard of a hair dryer lol

  7. Avataaar/Circle Created with python_avatars Chase DeBoard says:

    Love the sorta passive drying these do, usually pretty safe for leather.
    Apart from drying wet boots, it’s great for daily driver shoes and gets out yesterday’s foot moisture.

    hmm… no fan huh?
    just relying on convection current to drive air into boots i guess?

  9. Avataaar/Circle Created with python_avatars Me Here says:

    Boot warmers, not dryers, surely? Very nice when it's -30° out.

  10. Avataaar/Circle Created with python_avatars Mark Scheutzow says:

    For the US they probably parallel the same resistors.

  11. Avataaar/Circle Created with python_avatars Aesop McLean says:

    In Canada we have plastic spikes with holes in them. Put the spikes over the vents, and put your boots or gloves on the spike. Air from the vent dries them.

  12. Avataaar/Circle Created with python_avatars George Wood says:

    I might’ve had 2 too many so my ohms law might be suffering if they wired the resistors in parallel I could use them here in North America 🇺🇸 (different plug)

    Seen the 8 hole DM's with yellow laces in the thumbnail and I thought " uh oh Clive must have been a Skinhead back in the day.." 🤣

    I have a Peet..110 volt (120).. Been plugged in for 9 years.. Works flawless. Peace Rolfie (Ralph)
