Blowing hot and cold

I was right, it's the electrical unit in the CH Boiler that is on the blink. Well, it's on more than the blink, it's on fire: a contact was arc-ing and smoke was coming from it. So, the nice man from Shelford Services shut the system down and is going to get a replacement. One day soon.
In the meantime, while the days are glorious, ie, clear blue skies, the temperature plummets at night, which is why you won't recognise me after sunset as I turn into an Eskimo, layer upon layer to keep the Imperial Bones from cracking.
My computer problem? Don't ask. But it will get over, as my dear mother used to say, with the help of prayer and the PC Doctor from Thetford.
