    Yes. It will blow/overheat!

    Although check it because a lot of transformers will accept 110V - 240V.

    So you want to use a 110 V device on 230 V supply, is that what you're asking?

    If so I think Jonathan means "Yes" as in, it will overheat or blow a fuse...as in DO NOT do it!

    As above. You will be supplying it with double its rated load.

    Think you'd actually be supplying 4 times it's rated load. Around 86W by my calculations. That thing would melt for sure.

    Op, given that it's a device for heating something I doubt it has a transformer, probably a simple heating element so you most
    definitely cannot plug this in here.

    Yes sorry Redsie you are correct, il know in future not to pull figures off the top of my head without calculating.

    P= V x I
    I= 20w/110 I= 0.1818181A

    V = I x Z
    Z= 110v/0.1818181A Z= 605ohms

    P= V*squared/Z
    P= 240*squared/605ohms P=95.20w

    95.20watts
