Heat Equation - solved

I have finally solved a heat flow problem - the defective extension cord was to blame. With my new 2000-Watt heater/fan in action, cushions are drying, I'm sure. Alas - Gary's SSP06 wrap-up party turned into an all-nighter in Seven and I have to hope the bells of the cathedral will wake me from this strange loft in time to lead the Trek to Molsheim.
