Hi guys
sorry to jup in on the end , i bought tyre warmers from KLS --
www.kls.de i teamed up with 10 others and bought a set of GP-3D warmer with a 2 stage setting 60C and 80 C with a seamingly low power drain (nomal plug) heat up fast and with the 60C setting you can leave them on all day without and danger of damaging your tyres and just flick the switch over to 80C 20 mins befor you ride out they also us a carbon heat element rather that a metal wire for better heat transfer ...you have to ring for prices ect but they do team/club discount and also different coulor and lettering Hmmmmm nice.
