Heat Exchange

This one is a variation on a theme.

Today’s Gratitude Item: Finally getting my computer back from the technicians. They had to put on the software that they removed when they re-imaged my machine (long story). Whilst it’s still a case of ‘two steps forward, one step back’ at least some progress is being made. Needless to say have learned a lot from this week’s disasters so it’s not a total loss.
