Inside a boot dryer (possible Peet clone?)

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.
The heat source is two ceramic 700 ohm resistors with a power rating of 25W.
In the UK they are wired in series meaning there is 120V across each resistor. That calculates as a current of I=V/R I=120V/700ohm I=170mA
Power dissipation per resistor is P=IV P=0.17A*120V P=20.4W
In 100-120V countries the same 700 ohm resistors could be wired in parallel or two 330ohm or 390ohm resistors could be used in series.
